Notices of new or Uttle-hnown Genera and Species of Coleoptera.
By Francis P. Pascoe, F.L.S., &c.
Part I.
It is difficult to form any adequate idea of the number of new forms, to say nothing of new species of insects, which exist in, or are being constantly added to, our cabinets*. Many of these are almost hope-
* Mr. S. Stevens has just favoured me with the sight of a collection of Coleo- ptera (perhaps about a thousand species) made by Mr. Squire at Petropolia (a sort of Brazilian Cintra, and a short day's journey from Rio), and although the district has been repeatedly worked, and Mr. Squire was there scarcely two months, yet the result of his visit has been the discovery of a vast number of novelties and some new forms of a very interesting character.
Mr. F. P. Piiscoc on new Genera and Sjyecies 0/ Colcoptcra. .'^7
Icssly entombed in private as well as in public collections, or have long boon accumulating in my own. To record the most remarkable, and such, at the same time, as can easili/ be recognized by figures and descriptions, if confined to a private collection, is one of the objects of this Journal, and the following is the first of a series of papei-s which will be devoted to the Colcoptcra. As it will be im- possible to follow any systematic plan beyond the limits of each paper, a classified list will be given hereafter to diminish this incon- venience.
It must not be forgotten that many of the insects to be described will be either uniques, or, belonging to others, cannot therefore be mutilated by dissection ; but as every new genus will be figured, it is hoped that the absence of the usual analyses will not create any difficulty. Practically, we are satisfied with referring species to their genera from their external resemblances ; but although it is verj" often quite impossible to ascertain the affinities of an insect without dissection, there is the danger of attaching too great import- ance to organs whose characters cannot always be determined satis- factorily, and which, moreover, because they occm- in one species, are sometimes erroneously assumed to be present in others. Indeed, it may be doubted if even individual species are so invariable as to justify the minute descriptions of many naturalists.
A\Tiile believing in the existence of genera quite as much as in the existence of species, is it satisfactorily established that they can always be distinguished by technical characters, such as we are in the habit of emplojing ? In all large genera, I believe, it will be eventually found that they possess no one character in common that is not also possessed by the group or family to which they respect- ively belong, and hence it is quite natural that the limits of such genera cannot be verj^ strongly defined. This is especially the case in the Longicom families, which with endless differences in habit agree in a certain similarity of details, so that the generic characters often become mere questions of degree, — while, on the other hand, many Heteromera alike in habit are found to vary remarkably in structure, and in fact to belong to very different groups than those in which their general appearance would seem to place them.
These and other points of the same kind will be often exemplified in the course of these ' Notices ; ' but in considering the difficulties which beset aU attempts at a satisfactory limitation and arrange- ment of species into families, genera, &c., it will be as well to bear in mind the remark of our great naturalist, — " Nature is less of a svstematist than Man."

Omojphron Brettinghamce.
O. ovato-rotundatum, nitidum, testaceum ; capite^ prothoracis disco, ely- trisque (marginibus exceptis) viridi-seneis.
Hab. India (Dacca).
Shortly ovate or nearly orbicular, moderately convex, very smooth and shining ; head sparingly punctured, brassy-green ; labrum, epistome, and small triangular spot above the latter brownish-testaceous ; prothorax finely and remotely punctured, and with the elytra rich brassy-gTeen, bordered externally with testaceous, — the border much wider on the latter, which are also very finely punctured in rather distant rows; eyes and tips of the mandibles dark brown ; antennae, palpi, and legs pale testaceous ; body beneath with the sterna pitchy, the abdomen deep testaceous. Length 2 lines.
For the possession of this and many other Coleoptera from the same locality, I am indebted to Dr. Ernest Adams of University College, the author (;inter alia) of some exceedingly interesting and learned papers on the " Yemacular names of Insects," in the Transactions of the Philological Society, who received them from India*, where they were collected by Mrs. Brettingham (to whom I have dedicated the exquisite little Omophron just described) in the compound attached to the quarters of Charles Brettingham, Esq., in medical charge of the Kamroop Regiment of N'ative Infantry sta- tioned at Dacca. They comprised above seventy species, belonging to nearly as many genera. Of these there were only six or seven that were not represented in Europe, viz. Adoretus, Heteronychus, Anisotelus, Macratria, a Mtidulid, and two, or perhaps three, obscure Heteromerous genera, which I have not been able to refer to any hitherto published. Except that there were very few Staphylinidae, they were mostly such forms as would be found in this country in the debris of a flood ; and it is, therefore, most likely that they were collected in the rainy season. Dacca is nearly in the latitude of Calcutta, lies very low, and as it is subject to inundations from the Ganges, it is probable that it affords a larger proportion of European forms than would have been the case in a drier or more elevated district. So little is really known of the Entomology
* Upwards of a thousand specimens, some nearly an inch long, although gene- rally much smaller, enclosed in two large-sized pill-boxes, were transmitted by post in the ordinary way in a single letter. A wine cork hollowed out in the middle, and a Uttle trimmed at the sides, would be an excellent, and at all times available substitute for a box.

of India, that it would bo premature to speculate as to its cha- racter ; but idthough in its animal productions there is a remark- able amount of Northern temperate forms, they could never have been expected to predominate to such an extent in any one group, as it now appears they do, judging, however, solely from the facts here stated*. There is one point in connexion with this subject which can only be just alluded to here, viz. the apparent tendency of animals to migrate to the south, and not the reverse, or very slightly sof. The idea first occurred to me in noticing the very few Austra- lian forms of Coleoptera occurring in Mr. Wallace's Indian Island collections contrasted with the number of these Indian forms in Australia, especially its northern parts ; — compare also Natal \nth the Cape, or the United States -with Mexico or Cuba ; notice Upper Egj-pt, Arabia, Persia, itc, just receiving a tropical form here and there.
Casnonia [Carabidae].
LatreiUe, Icon, de Coleop. d'Europe, ed. 1. p. 77.
Casnonia aliena,
C. picea ; capita infra oculos profunde lunato-impresso ; prothorace capite breviore, postice transverse cori-ugato; elytris leviter striatis, singido macula flavescenti apicem versus ornate.
Hab. Australia (Moreton Bay).
Pitchy, shining ; head rather broad, a deep semicircular impression between the eyes and the epistome ; prothorax not so long as the head, somewhat elliptical, smooth anteriorly, but with delicate transverse folds behind ; elytra about the length of the head and thorax together, and three times the width of the latter at its base, faintly striated with an oblong yellowish patch towards the apex of each ; antennas dai*k brown ; legs pitchy, femora at the base and tibiae in the middle (nearly obsolete, however, in the anterior pair) testaceous-yellow ; body beneath pitchy-brown, shining. Length 6 lines.
Although the genus Casnonia is found in India as weU as in South America, this is, I believe, the only species yet detected in
* While this sheet was passing through the press, Dr. Adams received another collection from Dacca, evidently made in a more favourable season ; still, altlioiigli there is an addition of many tropical genera, European vastly predominate ; a}id it is worth notice, that nearly all these tropical genera liave a very wide range, as for example, Anthia, Chrysochroa, Protcetia, Xyloni/chus, Ccrosfenia, Olenocamptus, Gknea, Apomecyna, Batocera, Xylorhiza, &c., all of wliich are represented by the commonest species.
t The same tendency has been noticed in plants, so far as those of America and Australia are concerned.

Australia, and so far it appears to be absent from the Indian Islands. The present insect is rather larger, with a shorter thorax, than any Casnonice that I am acquainted mth.
SosTEA [Parnidae].
Head small, completely retractile within the thorax. Antennae re- ceived, in repose, in a cavity beneath the eye ; 11-jointed, the first very large, laminate, the second dilated inferiorly, the remainder forming a compact fiabellate mass. Eyes rounded, entire. Mandibles bidentate at the apex. Maxillae with lobes, short and broad. Maxillary palpi short, the last joint very large, cylindrical ; the labial claviform. Mentum transverse, lobed in front. Labium dilated anteriorly. Prothorax transverse, convex, nearly semicircular. Elytra ovato-triangiilar, very convex, gibbous towards the base. Legs slender, coxae distant, tarsi short. Prosternum received in a notch of the mesosternum.
These characters are drawn up exclusively from S. Westwoodii ; but the other species so completely resemble it, that there can be no doubt as to theii' generic identity. In all, the elytra have nine rows of punctures on each. The structure of the antennae will be better comprehended by the figure* than by any description, but owing to their minuteness, I was unable to detach completely the large basal joint ; when in repose it appears to act as a valve, closing in entirely the rest of this organ : all the joints composing the fiabellate mass are what may be called boat-shaped, except the last, each being re- ceived at its base, and for the greater part of its length, in the con- cavity of the preceding one, — the first, however, being so much more dilated as so far to enclose the succeeding or fouilh joint, that it is only visible at its free extremity ; and unless this is attended to, the antennae Avill appear to be composed of ten joints only.
I have dedicated the first species to J. 0. Westwood, Esq., M.A., F.L.S., (ke., and have adopted his views respecting the position of the genus, of which, indeed, there can be no doubt.
Sostea Westivoodii (PI. II. fig. 6.)
S. ovata, fusco-atra, nitida, longe setosaj scutello triangularis pedibus

tSostea carhonaria. S. suboblong-o-ovatn, atra, nitida, breviter setosa; scutello oblonjro ; tarsia
riifest'oiitibus. Hob. Moluccas (Iktehian).
Ovate, a little inclining- to oblong, shining black, with short scattered black setose haira ; scutelluni oblong; tarsi fen*iiginous-red. Length U line.
Smaller than the last, with which it agrees in shape (except that it is a little longer proportionally), punctuation, ttc. ; but it is at once distinguished by its oblong-ovate scutellum.
Sosfea ceneipennis. S. ovata, nigra, nitida, longe setosa ; scutello triangiilari ; elytris eeneis ;
pedibiis rufo-ferrugineis. Hub. Borneo (Sai-awak).
Ovate, shining bluish-black, with long setose hairs ; prothorax rather sparingly punctured ; scutellum triangular ; elytra brassy ; legs reddish- ferruginous. Length 2^ lines.
Sostea cyanoptera. S. ovata, atra, nitida, setosa ; scutello triangulari ; elytris Irete cyaneis ;
pedibus feiTugineis. Hab. Borneo (Sarawak).
Ovate, shining black, with moderately long setose hairs ; prothorax finely punctured ; scutellum triangular ; elytra rich ultramarine blue ; antennae pale testaceous ; legs ferruginous. Length 2 lines.
Sostea secuta. S. ovata, fusca, subnitida, setosa ; prothorace g;riseo-pubescenti ; elytris

Byesax [Colydiidae].
Head small, vertical, hidden above by the prothorax. Eyes large, rounded, partially divided by the cheek. Antennae retractile, shoi-t, gradually increasing upwards; the first joint rather slender, the second shortest, the third and fourth longest and equal, the fifth triangular, the sixth -to the tenth transverse, the eleventh shortly ovoid. Labrum and epistome very small. Palpi short, linear, the terminal joint ovate. [Mentuui transverse ; labium oblong, entire, as seen in situ.'] Prothorax very transverse, gibbous in the middle, bicornuted anteriorly, the mar- gins dilated and crenidate. Elj'^tra short, very convex, tuberculate, with broad crenulate margins. Legs of moderate size ; tarsi with the first three joints veiy short, equal, with fine hairs beneath. Presternum strongly compressed. Mesosternum toothed.
In habit this genus closely resembles the Diaperis horrida, 01., with which Mr. Walker's Askla horrida is probably identical. Its real affinity, however, if we are to be guided by the tetramerous tarsi, is with Endophloeus, Pristoderus, and some other little-known and even undescribed forms among the Colydiida3, but diifering from all in its head being perfectly hidden by the prothorax when viewed from above*.
Byrsax coenosus. (PI. III. fig. 7.) B. rotundatus, pellicula ftisco-murina indutus, infra piceus ; antennis
palpisque brunneis. Hub. Singapore.
Nearly orbicular, very convex, dark brown, covered wnth a thin vello wish-brown pellicle, which readily peels off*; prothorax with two short porrect horns in front ; scutellum small, triangular ; elytra each with three tubercles placed near the suture, the two anterior much the largest ; body beneath pitchy ; antennae and palpi light brown. Length 4 lines.
The figures represent the head as seen from below, and the inter- mediate tarsus.

S. subdepressus, nigi-o-piceus ; prothorace aequo ; elytris rotimdatis, basi paullo convexis.
Hab. Borneo (Sarawak).
Subdepressed, dark pitchy inclining to black ; head slightly convex, finely punctured ; prothorax smooth, even, with minute areolated punctures, its anterior angles rounded j scutellum very large, triangular ; elytra with a nearly rounded outline, the base towards the shoulders very slightly convex, covered with delicate elongate punctures ; an- tennae, palpi, body beneath, and legs, where not exposed when the animal is rolled up, feiTuginous. Length li line.
The occurrence of a genus so purely American as Sphceromorphus in Borneo may w^ell excite surprise, as, a priori, it might have been supposed, if any of that group occurred at all in the Indian Archi- pelago, it would have been either a new form, or the Madagascar Synarmostes. I cannot, however, find, from dissection o{S. acroinialis, any variation of character sufficiently marked to warrant its separa- tion from Sphceromorphus. Dedicated to Mr. A. Wallace, to whose researches in the Indian Archipelago we owe so much.

Scrohiger albocinctus. S. ater; prothorace subtilissime punctate j elytris fasciis duabus albis,
una subobsoleta, altera, pone medio, obliqua. Hab. Moreton Bay.
Nearly allied to S. idoneus, Newm., but the eyes are smaller and less prominent, the prothorax more finely punctured, the anterior band on the elytra nearly obsolete and more median, and the posterior directly oblique, not curved. Length 5 lines.
CoRMODEs [Cleridae]. Head rather short, broad in front. Eyes ovate, vertical, scarcely emar- ginate. Antennae as long as the thorax, arising laterally in front of the eyes, 11-jointed, the first largest, the second shorter than the third, the last three foraiing a slender pointed club. Palpi with the terminal joint of the labial secmiform, of the maxillary cylindrical. Labrum small, hairy. Prothorax subdepressed, rounded in fi*ont and at the sides, contracted posteriorly, — the pronotum confounded with the para- pleura. Scutellum transverse. Elytra depressed, naiTowed at the base, gradually expanding at the sides, with a strongly marked carina at the shoulder, but no humeral angle. Wings none. Legs stout, femora clavate, tibiae and tarsi short, the first tarsal joint nearly covered above by the second j claws simple. Abdomen of five segments. Although very dissimilar in habit to the Cleridae in general, there is no doubt that this genus is closely allied to Natalis. It is, I believe, the only one of its family without vdngs, — a condition due, as Mr. Darwin tells us, in reference to other insular apterous Co- leoptera, to " the action of natural selection, but combined probably with disuse," and therefore it would not, perhaps, be very difficult for the advocates of his theory to suppose Cormodes a descendant of Natalis, to which it certainly bears a very peculiar resemblance. The absence of a real humeral angle, but its simulation by an ele- vated and narrow carina (absent in all other Cleridae), and the, in other respects, well- developed elytra, do not appear to lead to the conclusion of the gradual reduction of the wings which such an ex- planation implies, because corresponding with this presumed reduc- tion we have an unaccountable and apparently unnecessary increase of the elytra, combined, however, with the absorption of the humeral angle. I possess a Longicorn, closely allied to Mr. WoUaston's oceanic genus Deucalion, also without humeral angles, but having perfect, although excessively small, wings, and of course entirely useless for the purpose of flight ; but in this case the wings might at any time

In these and other instances of abnormal variation, which in almost every case seem to have some speciality of their own, we look in vain for the '* advantage " which is supposed to have been acquired in the "■ struggle for life." An insect so suggestive of Mr. Darwin's theory should appropriately bear his name.

Aulicus instahiUs, Newm., the type of the genus, is such a variable insect, that it is quite possible this may be but one of its protean forms ; nevertheless, besides its smaller size, it is more convex, the prothorax narrower and less depressed, its greatest breadth being behind the middle, and the posterior and anterior margins being nearly equal ; its head is also shorter, the eyes proportionally larger, and the antennae longer ; moreover I have never seen any specimen of A. histahilis approaching this in colour.

Rather narrow and depressed, black, shining, finely punctured, covered Avitli short setulose hairs ; head scarcely as broad as the pro- thorax, black; oral organs and palpi yellow, except the tips of the man- dibles, which are black ; prothorax reddish -yellow, the anterior border black, three mammillated prominences on the disc, placed transversely ; scutellum small, black ; elytra deep black, shoulders rather prominent ; femora and tarsi black, coxae and tibise yellow; antennae black, the basal joint yellow; body beneath black, shining, except the prothorax, which is yellow. Length 3 lines. The joints of the antennae are strongly produced on one side, as
in the majority of the species of this genus, beginning from the
third. I have only seen a single specimen, which is in my o-^ti
collection.
Choeesine [Cleridae].
Head small, transversely triangidar in front, slightly exsei*ted behind. Eyes rounded, prominent, entire. Antennae 11-jointed, linear, not half the length of the body, arising in front of the eyes; the first joint twice as long as the second, which is only a little shorter than the third, the fourth and fifth slightly longer, the rest subequal. Labrum transverse, entire. Mandibles strongly curved, bidentate at the apex. Palpi clavi- fomi, the joints very short and transverse, the maxillary much larger than the labial. Maxillae roimded, two-lobed. Labium obovate. Pro- thorax subquadrate, constricted posteriorly before the base ; pronotum distinct from the parapleurae. Scutellum small, triangular. Elj-tra convex, nearly hemispherical, advancing at their insei-tion on the base of the prothorax. Legs slender; first joint of the anterior tarsi nearly covered by the second above ; the middle and posterior tarsi with all the joints fi'ee, the three intermediate of all fiu^nished with lamellae. Abdomen slender, of six ? segments.
The habit of this very remarkable insect approaches in some respects the Melyrideous genus Chalcas ; the structure of the tarsi, however, is that of a Clerid, and although a very isolated form, I see no difficulty in placing it in the subfamily Enopliinae.

DoLiEMA [Tenebrionidae].
Head short, transverse. Eyes lateral, contiguous to the prothorax, par- tially divided by the antennary orbit, larger below than above. Labruni small, rounded in front. Mandibles thin, triangular, bidentate at the apex. Antennae short, perfoliate, moniliform, and gradually increasing in thickness from the fourth joint to the seventh or eighth. Mentum subquadrate. Labium small, entire ; labial palpi stout, clavate, the maxillary with its terminal joint subsecuriform. Maxillae two-lobed, the lobes ciliated (the inner armed* ?). Prothorax depressed, contracted behind, broadly emarginate in front, its anterior angles rounded. Elytra very depressed, parallel, abruptly bent down at the sides ; the epipleural plait narrow, terminating before reaching the apex. Legs short ; coxae distant ; tibiae spmTed, the anterior serrated externally ; tarsi slender, the first joint of the posterior as long as the last. Pro- and mesosterna broad and flat, the former roimded posteriorly, and received into a slight emargination of the mesosternum.
A remarkable genus, which might readily be taken for a Pla- tisus, but which is very closely allied to, if not identical with, Mr. "Wollaston's Adelina. As, however, the characters of his genus were drawn up from an insect which he suspects may not be con- generic with certain representatives in the British Museum of M. Chevrolat's original, but unpublished Adelina (but which unques- tionably includes the species now to be described), and his detailed description differs in several, although somewhat secondary points, from that given above, and he has taken no notice of the peculiar elytra, I have thought it better to consider my species the type of another group ; and I do so with less hesitation, as the name of Adelina has been long preoccupied by a genus of Gasteropods. Doliema, thus restricted, has a remarkable range, D. platisoides oc- curring in Ceylon, Manilla, and the Moluccas, while a closely- allied species, differing in nothing apparently but in having a somewhat broader head, is found in the valley of the Amazons.

Stiljpnonotus eurypiformis (named, but not described, by Mr. G. R. Gray in the Englisli edition of the ' Eegne Animal ') appears to me to be referable to Mr. Kirby's Eurypus, a genus not alluded to by M. Lacordaii-e in his great work. Mr. Kirby's species, E. ruhenSy from the fig-ure, seems to be a much broader insect than the present, which it is not impossible may be identical with Olivier's Tenehrio nitens. The pronotum is confounded with the parapleurse, and the anterior coxte are contiguous and greatly exserted, two characters which do not accord well with the Tenebrionidae : the possession of antennary orbits forbids its association with Lagriidae. In habit it is shghtly assimilated to Camaria.
CEdemutes [Helopidae].
Head transversely subquadrate ; epistome large, deeply inserted m fii'ont. Labnun short, transverse, broadly emarginate. Eyes rather broad, sub- lunate. Last joint of the labial palpi seciu-iform, of the maxillary nar- rowly triangular. Antennae very short, clavate, 11-jointed, the first joint nearly concealed by the antennaiy orbit, the second short, third longest, the rest gradually increasing in breadth to the seventh, which, with the remainder, forms a sort of club. Prothorax transverse, slightly convex, carinated at its sides, the base closely applied to the elytra. Scutellum small. Elytra ovate, very convex.

Length 12 lines {S), 14 lines ( $ ).
Elacatis [Melandryidse].
Head broadly triangular, as wide as the prothorax. Eyes distinct, large, ovate, contiguous to the prothorax. Antennae arising from beneath a narrow orbit, eleven-jointed, the two basal joints thick, the second shortest, the third to the eighth subequal, slender, the last three forming a short ovate club. Labrum small, rounded anteriorly. Mandibles short, with a single tooth in the middle. Palpi robust, claviform. Maxillae with two ciliated lobes. Labium small, subcordate. Mentum transverse. Prothorax subquadrate, posterior angle emarginate, the parapleurae distinct. Elytra as broad as the thorax, tapering posteriorly, the epipleural plait very narrow. Legs short ; anterior coxae conical, contiguous, their acetabula closed behind, the intermediate subapproxi- mate, oblique, furnished with trochanters, the posterior transverse ; tibiae spurred; tarsi very slender, the first joint long, the penidtimate entire ; claws simple. Mesosternum narrow, truncate behind.
Genera and Species 0/ Colcopteru. 53
I have not placed tliis genus among the Melundryidce without hesitation, on account of its antennary orbits, and its acetabula closed behind ; on the other hand, its paraplcurie, distinct from the pronotum, make its location in any other family still more difficult. Except the comparative shortness of the maxillary palpi, it agrees with the Melandryida) in most of the characters given by M. Lacor- daire, according also in form with some of its genera, "udthout, how- ever, being related to any of them. Like Tetmtoma, it has the antennae terminating in a club, but only composed of three joints. In the drawing the maxillarj^ lobes are much too large, compared to their palpus.
Elacatis delusa. (PI. II. tig. 5.)
-E. griseo-testacea, punctulata ; elytris fasciis tribus dentatis, maculaque basali nigris.
Hub. Borneo (Sarawak) ; New Guinea (Dorey).
Greyish-testaceous, finely punctm'ed, a short setulose hair arising from each pimctm-e ; prothorax with three or four very minute teeth at the side, and a shallow transverse impression near the base ; scuteUuni long and narrow; elytra wdth three black, toothed bands, the first often interrupted or replaced by a few spots ; a patch of the same colom*, also sometimes broken up into spots, at the base near the scuteUmn ; antennoe and legs testaceous-yellow, more or less clouded with brown ; body beneath ferruginous, slightly tomentose. Length 1^-2 lines.
My New Guinea specimen agrees perfectly well with those from Borneo ; but they aU. vary a little in colour, some being darker than others, and the black band and scuteUar patch being more or less interrupted. A second species, and a much finer one, from the Moluccas, is in the collection of W. W. Saunders, Esq.
BioPHiDA [Melandryidae ?].
Head moderately long, tumid in front, suddenly contracted behind into a nan-ow neck. Eyes distant, lateral, reniform. Antennae arising close to the eye, filiform, half as long as the body, 11-jointed ; the second very short, the rest subequal. Labium transverse, inserted below the line of the front. Labial palpi filiform ; the maxillary elongate, with the last joint narrowly secm-iform. Prothorax depressed, semicircular, as wide as the elytra behind, its parapleurie distinct. Elytra depressed, rather broader behind. Legs moderate ; anterior and middle coxte con- tiguous, the former conical and elongate ; tibiae spurred ; tarsi slender, the first joint of the fom- posterior as long or longer than the rest together, the penultimate bilobed ; claws undivided, strongly toothed beneath.
This is another of those puzzling genera, of which there are so
54 Mr. F. P. Pascoe on some neiu or little-Tcnown
many among the Heteromera ; in its habit it resembles Scraptia ; but as the more important characters are those of Melandryidse, and that family is also one which contains several anomalous forms, it seems less objectionable to place it in that group than in any other.

Entirely of a light-brownish testaceous colour, rather closely covered with short stiiRsh paler hau^s j a large fovea on each side of the pro- thorax near the posterior angle ; scutellum transverse, rounded behind j eyes a little darker. Length 4 lines.
IscHALiA [Pedilidae ?].
Head small, contracted behind, and narrowed anteriorly below the eyes. Antennae shorter than the body, linear, 11-jointedj second joint smallest, the rest subequal. Eyes reniform. Epistome and labrum large, covering the mandibles. Maxillary palpi robust, the last joint secm^iform ; labial much shorter, terminating in a broad triangular joint. Maxillae short, obtuse. Prothorax narrowed anteriorly, irregular above, its posterior angles produced, the epiplem'se confounded with the pronotimi. Elytra broader than the prothorax, subparallel, bent at the side, and concave on the disc, the epipleural plait narrow. Legs moderate, anterior acetabula open behind j all the coxge approximate, the anterior and intermediate conical ; tibiae unarmed ; tarsi short, first joint longer than the rest together, the penultimate bilobed ; claws simple.
I refer this genus doubtfully to Pedilidae, notwithstanding that it agrees in two characters which M. Lacordaire considers of high im- portance, viz. the anterior acetabula largely open behind, and the complete contiguity of the posterior coxae. The family, however, as it stands at present, is not a satisfactory one, and its learned pro- poser will probably see reasons for modifying it eventually.

Emydodes [Lagriidae].
Head very small, rounded behind the eyes, then contracting into a neck, which is nearly immersed in the prothorax. Eyes large, oblong, emar- ginate, transverse, and approximating both above and beneath. Labial palpi very small ; maxillary elongate, the temiinal joint ovate, pointed. Antennae robust, shorter than the body, arising close to the eye, the first joint tumid, the second very short, the third to the tenth thick, triangular, with a bifid prolongation at the apex of each on one side, the eleventh elongate-ovate. Prothorax slightly transverse, roimded anteriorly, twice the breadth of the head, but much narrower at the base than the elytra, its parapleurae confoimded with the pronotum. Elytra depressed, with a subovate outline, the epipleura strongly bent in beneath. Legs robust ; anterior coxfe large, approximate, shortly cylin- drical ; tibiae not spurred, the four posterior thickened in the middle ; tarsi short, the penultimate joint subbilobed; claws undivided, slightly toothed at the base.
A very curious genus, which, if rightly referred to Lagriidae (and of this I have little doubt), differs entirely in the remarkable structiu'e of the antennae, in which it somewhat resembles the Pyrochroidae. From my solitary specimen, I cannot make sure that the anterior acetabula are closed ; they appear to be so, however. As far as I

Legs slen- der; tibiae bicalcarate; penultimate joints of all the tarsi small, tri- angular.
Differs from Cantharis, with which only it is likely to be con- founded, in the short penultimate joint of its tarsi : the claws appear to be undivided, from the close application of their two divisions.

I have elsewhere mentioned my suspicions that this genus is syno- njmous with Dendropemon, Schon., and M. Jekel is inclined to take the same view of it ; as, however, the name was previously used by Perty, or what will be considered to amount to the same thing — for his orthography was Dendropoemon — another name must be adopted, and Nessia having been aj^plied to a group of Saurians, I have thought a modification of it to Nessiara will be attended with the least inconvenience. Stenocerus platip>ennis ! Montrou., is evi- dently nearly aUied to the species just described, and his three other Stenoceri probably belong likewise to this genus. S.

Elono-ate, subcylindrieal, with a short dark brow-n tomentum, slightly varied with greyish-white ; head shortly ovate, eyes rather large ; pro- thorax a little longer than wide, varied anteriorly and at the sides with greyish ; scutellum minute ; elytra punctate-striate, the alternate interstices raised and spotted with white, the spots a little before, as well as behind the middle, elongate, forming an indistinct, oblique, band-like mark ; antennae dark brown ; legs paler, varied mth greyish ; body beneath greyish-brown. Length 3 lines.
This species, together with B. per eg Anus and B. ingratus from Port Essington, described by me in a recent number of the ' Annals and Magazine of Natural History' (Dec. 1859, pp. 432, 433), itc, differ from B. nitidicutis, Jekel, the iy^o of the genus, in their nar- rower and more elongate form, and their brown, not ashy, colour.
DnfORnoPALA [Curculionidae].
ead small, abruptly contracted below the eyes into a short rostrum. Eyes large, roimd, prominent. Antennae short, sti*aight, arising close to the eyes in a cavity formed between them and a short thick process, twelve-jointed, the first subppiform, elongate, the second shorter, sub- cylindrical, the third to the eighth slender, gradually diminishing in length, the last four forming an ovate compact club. Prothorax sub- triangular, lobed at the base, narrow anteriorly, irregular above. Eh^ra large, much wider than the prothorax at the base, very irregular and spinous. Anterior and iutennediate legs moderate, the femora clavate and unidentate beneath, each tibia with a single ciu-ved spm*; the posterior longer, their femora slender at the base, abruptly clavate at the apex, and armed with a strong tooth, their tibioe strongly com- pressed and curved; the tarsi of all short, the penultimate joints broadly lobed; claws toothed beneath; anterior coxae approximate, intermediate and posterior widely apart. Meso- and metasterua very large.
The affinity of this genus is no doubt with Tachygonm, and judging from its posterior legs, it is probably also saltatorial. As the import-

ance of the geniculation of the antennae is now only recognized as a secondary character, I think M. Jekel* has done good service in referring all the groups of Schonherr's Orthocerati, after eliminating those which evidently belonged to the true Curculionidae, to four families. Tachygonus is one of the genera so removed, and this M. Jekel seems inclined to place near CeutorJiynchus.

The figure, which is in no degree exaggerated, wiU give a better idea of this singular little insect than the most lengthened descrip- tion. It was taken, with other very interesting species, by an Enghsh officer at the time of our recent occupation of Eangoon.

From the slender and elongated tarsi, particularly the posterior, I should be inclined to refer this genus to the neighbourhood of (Edopeza, rather than to Monohammuii,v^\\cYc formerly I had doubt- fully placed it. Except the slightest possible variation in the patches on the elytra, there appears to be no difference between the Batchian and Dory insects.

Calonecrus rufipes.
C. rufo-flava ; oculis elytrisqiie nigris.
Jlab. Borneo.
Entirely reddish -yellow, except the eyes and elytra, which are hlack ; head and prothorax finely, elytra more coarsely punctured ; sides of the latter, pygidium, femora and tihise pubescent. Length 3 lines.
Proportionally a more slender form than C. Wallacei, Thoms., and altogether less robust, with the antennae and legs reddish-yeUow, and not black as in that species.
Peostomis [Cucujidse]. LatreiUe, Fam. Nat. du Regno An. p. 397.
Prostomis morsitans. (PL V. fig. 6.)
P. oblongus, testaceus vel piceo-testaceus ; prothorace transverse j elytris pimctato-striatis.
Hah. India (Darjeeling).
Larger and proportionally broader than P. mandihidans, the pro- thorax transverse, the antennae shorter, &c. Length 4 lines.
In the only two specimens which I have seen (in the British Museum), one is very much darker than the other. Mr. Bakewell has another very distinct species from Melbourne.
Ehyssopeea [Cucujidae].
Head small, slightly exserted, nan*owed anteriorly. Antennae of moderate length, the first joint thick, abruptly contracted at its base, the rest more or less ovato-triangular, the last three stouter, forming a loose oblong club. Eyes transverse, rather prominent. Mandibles bidentate at the apex. Labrum long, narrow, roimded anteriorly. Palpi claviform, the last joint broadly ovate, obliquely truncate, the maxillary much larger than the labial, and widely separated at their origin. Mentum subqua- drate, not larger than the labium, which is transverse and emarginate anteriorly ; external maxillary lobe broad, strongly ciliated, inner very narrow. Prothorax subcordate, scarcely sinuated in front. Elytra much broader than the prothorax, parallel, slightly depressed. Legs

JR. fusca, sparse flavo-pubescens ; prothoracis basi latiuscula; clytris areolatis.
JIab. Tai^mania.
Opake iimber-browu, with a sparse yellowish or almost golden pubes- cence, especially on the head and prothorax, the latter about as broad as long, rounded at- the side, produced into a short acute angle ante- riorly and slightly contracted behind, with four tubercles on its disc ; scutellum transverse ; elytra with their external margins serrated, each with three rows of coarsely punctured hexagonal nearly equal cells, the walls of which are formed by narrow raised lines ; labrum, palpi, and legs ferruginous. Leng-th 4 lines.
Rhyssopera illota. (PI. VII. fig. 4, trophi only.)
It. fusca, sparse griseo-pubescens ; prothorace longiore, basi angustata ; elytris subareolatis.
Hah. Australia (^Melbourne).
Like the last, but the prothorax is longer and much narrower poste- riorly, the lines bounding the areola? and punctures less inarked, and the pubescence of a greyer hue.
Glgeania [Trogositidae].
Head small, rounded and dilated below the eyes, emarginate in fi-ont. The labrum entire. Antennae short, eleven-jointed, the last three fonn- ing a subunilateral, compressed club. Eyes round, prominent. Mandi- bles entu-e at the apex, toothed in the middle. Palpi robust, with the terminal joint subcylindrical ; maxillary lobes finely toothed, the inner narrow. Labium quadrate, slightly fringed. Mentum large, quadrate. Prothorax subquadrate, narrower anteriorly, broadly sulcated at the side, and slightly margined. Elytra scarcely broader than the pro- thorax, subdepressed, the sides nearly parallel. All the coxse distant ; femora broad, compressed ; tibiae dilated below, terminating in a series of small teeth; tarsi slender, slightly ciliated beneath, the basal joint minute, the second as long or longer than the third and fourth together ; claws toothed at the base. Prostemum rounded behind ; mesosteraimi depressed.
The Trogositidae do not appear to have any very definite characters, if we except the minuteness of the first tarsal joint, and include genera varying very much in their form. Of the foiu' subfamilies

G. fuseo-picea, subla3vigata ; prothorace antics excavato ; elytris seriatim punctatis.
Hab. Brazil (Rio).
Rather depressed, dark pitchy-brown, nearly smooth and shining ; head and prothorax minutely punctured, the latter with a long V-shaped excavation in front, with the side broadly and deeply grooved, the groove bounded internally by a gradually elevated ridge, which ante- riorly forms a well-marked angular process projecting slightly over the head, the external border of the groove formed "by a narrow uniform line, parallel to, and very slightly removed from the margin of the pro- thorax ; scutellum very transverse ; elytra with about seven rows of minute punctures on each, the shoulder with a short broad ridge gra- dually passing into the disc posteriorly ; anterior and intermediate tibiae rounded and denticulate externally at the extremity, with the posterior strongly spurred internally ; body beneath scarcely punc- tured.

Length 4 lines.
In this cui'ious species, the lines on the elytra are nearly covered by the longer and more densely set scales. In all the Australian and New Zealand Leperlnce which I have examined, I have never noticed any other than simple, undivided eyes.

Length 2^ lines.
A broader species than the last, with the prothorax especially di- lated at the sides and deeply emarginate anteriorly ; hereafter it may be found necessary to separate it generically from Bitoma.
Bitoma jejuna.
B. angusta, rufo-brunnea ; prothorace quadrato, granulato, utrinque tri- costato, costa interna antica abbreviata.
Hab. BrazU (Rio).

Closely allied to the former, but is smaller, less convex, the elytra nan'ower, and their base being depressed, they are on the same line with the prothorax ; the disposition of the tubercles is almost precisely the same, except perhaps that they may be a trifle less marked ; the colour in both species is somewhat variable.

104 Mr. F. P. Pascoe on some new or little-Tcnown
Rather depressed, dark bro^vn, tonientose ; sides of the protliorax, and a large patch on the disc of the elytra, which, commencing at the base, is contracted in the middle and again expanded behind, and a smaller spot at the apex, greyish -white ; disposition of the tubercles (which are all more or less conical) nearly as in the last; antennae, palpi, and legs dull reddish-brown ; under surface dark brown, covered with nimierous small tubercles, and but slightly pubescent. Length 2i lines.
The few characters which Erichson has given of Rechodes accord perfectly well with the insects described above, except that the last joint of the maxillary palpi is scarcely securiform, although very broad and truncate. Rechodes is closely allied to Ulonotus and En- dophloeus. To the former of these genera, M. Lacordaire refers, and I think correctly, BoUtophagus antarcticus, White ; and I would also refer to it Asida serricoUis, Hope. The genus Pristoderus of the latter author, founded on the Dermestes scaber, Fab., is probably identical with Ulonotus.
DiSTAPHYLA [Colydiidae].
Head small, transverse, scarcely visible from above, slightly dilated below the eyes, with a broad antennary gi'oove beneath. Antennae short, stout, 11-jointed, the two basal incrassated, the third longer than the rest, which are very transverse, the last two forming a short compressed club. Eyes large, round. Mandibles bidentate at the apex. Palpi robust, the terminal joint of the maxillary elongate, subcylindric, of the labial obovate; maxillary lobes narrow, ciliated. Labium very small, subcordate, fringed with long cilia. Mentum large, narrowed in front, rounded and dilated at the sides. Prothorax nearly qua- drate, very irregular anteriorly, the margin granidate and setose. Elytra elongate, subcylindrical. Legs short j coxae not contiguous ; tibiae gi-adually enlarging at the extremity, teraiinated by two small spurs, and bordered externally ^dth a row of stiff setae ; tarsi with the three basal joints short, hairy below. Prosternum rounded posteriorly, the mesosternum depressed.
Judging from the position which Erichson has assigned to his genus Phloeonemus, this must be a near ally, although it cannot be by any means likened to Colohicus.

A. rufo-picea, fulvescenti-hirta ; elytris subseriatim tuberculatis, tuberculis setiferis, fasciculis sextis nigris in medio obsitis; pedibus ferrugineis nigro variis.
JSah. Brazil (Rio).
Reddish-pitchy, rather sparingly clothed with short, scale-like, grey- ish-yellow or almost golden hairs ; head and prothorax with a few grey- ish seta?, the latter with about five dark spots on its disc ; scutellum rounded behind, closely covered with white hairs ; elytra uneven, with several small granular tubercles, ranged in more or less inter- rupted lines, each tubercle bearing at its apex a black erect rigid seta, in the centre six dense fascicles of stiff black hairs, the first and third of these nearer the suture than the second, an oblique stripe (composed of more closely set hairs) below each shoulder, and towards the apex another oblique patch of pure white hairs (composed, however, of two distinct spots) ; legs dark ferruginous, with scattered grey hairs, the femora varied with black, the tibiae with a black ring in the middle ; antennae and palpi pitchy-ferruginous ; body beneath pitchy-brown with pale gi'eyish hairs. Length 3 lines.
This appears to differ from A. tuberculifera, Biu-m. (which, however, I have not seen) in its larger size, the black fascicles, the yellow, almost golden, tinge of its scale-like hairs, the absence of the shining chestnut colour of the apices of the tibiae, knees, tarsi, &c. Bur- meister in his description of this genus has overlooked the basal joint of the antennae, and describes the second (last) joint of the club as composed really of two, soldered together, and in this he is followed by M. Lacordaire. I can find no trace of any such union, which, if it existed, would give twelve joints to the antenna?, and not eleven.

Differs from the last in its much smaller size, comparatively naiTower and longer elytra, in the more nmnerous tubercles, and brown fascicles of hairs, the almost unvar^dng hue of the pubescence, although near the shoulder and apex may be traced rather more densely set patches of 'hairs than elsewhere, and the more uniform colour of the legs.

Head vertical, rounded in front, and prolonged at the sides into two short peduncles bearing the eyes. Antennae short, eleven-jointed, the last two forming a short ovate club. Prothorax short, very transverse, narrower behind, broader than the head anteriorly, the sides strongly denticulate. Elytra nearly regular above, not broader, except at the base, than the prothorax. Legs slender, first tarsal joint scarcely longer than the second.
The other characters of this genus are the same as those of Acropis, to which, indeed, it is nearly allied ; the form, however, of the pro- thorax, added to the apparent absence of asperities, and the peculiar scaly crust, which covers the whole of the upper surface, as if a layer of opake varnish had been applied to it, obviously prevent its union with that genus. The shortness of the first tarsal joint, being more of a comparative character, is, perhaps, of less importance.

Obloug, broAMi ?, covered above as well as beneath witli a scaly crust of a pale yellowish or greenish grey, with very short hooked hairs, particularly on the margins of the prothorax and elytra, curving for- wards on the former, and backwards on the latter 5 head (including the peduncles) narrower than the prothorax, this with seven well-marked but obtuse teeth on each side ; scutelluni punctiforni ; elytra a little wider posteriorly, each with three very slightly raised gibbosities near the sutiu'e, another at the shoulder, and externally towards the apex two or three more, but which are considerably less prominent ; antennae pitchy, shorter than half the length of the head ; legs pitchy ; eyes dark browii. Length 1^ line.
In one of the two specimens now before me, the hairs are scarcely evident even on the margins, being, apparently, more enveloped by the scaly layer described above. In Mr. Fry's collection.
ExnELEMA [Colydiidae].
Head vertical, rounded anteriorly, and prolonged at the side into a short peduncle bearing the eye. Antennae as in Acropis, but more robust. Labium short, transverse, fringed with long hairs. Maxillary palpi robust, the terminal joint short, stout, obliquely truncate ; the labial -vsath the two basal joints small, the third large, broadly subovate, slightly truncate. Mentum quadrate, very large. Prothorax as broad as the head, transverse, regidar and convex above, naiTowed anteriorly, the sides margined. Elytra oblong, nearly parallel, the surface smooth and regular. Legs rather slender ; tibiae not ciliated extemall}^, ter- minated by two short spines. Prostemum produced behind.
The above include the characters which, combined with the total absence of tubercles, chiefly separate this genus from Acropis.

Larger and stouter in proportion in all its parts than the Cey- lonese D. porosus, but otherwise very closely allied.
I am unable, at present, to give any oral details of this (jurious genus, which Mr. Walker has only very briefly characterized, at the same time associating it with the Hydrophilidse ; it is, however, an undoubted Colydian, and evidently nearly allied to Emmaglceus of M. Leon Pairmaire. The large primo-abdominal segment and distant posterior coxae suggest also an affinity with Bothrideres and Berata- phrus ; but its head, vestiture, and habit altogether, point to a distinct subfamily. It may be mentioned that all the coxae are widely apart; the femora canaliculate beneath for the reception of the tibiae, which are fringed with stiff hairs externally, and the anterior ter- minated by two spines, the inner of which is much longer and curved, whilst the outer, under a strong lens, is seen to be tridentate ; the mouth is almost entirely closed below by the prolonged mentum ? (as in Berataphrus), the small, pointed maxillary palpi protruding at the sides.

Anaemostes [Colydiidae].
Head subquadrate. Antennae short, eleven-jointed, the two basal incras- sated, the third longest, the rest gradually decreasing in length to the eighth, the last three forming an ovate, compressed, perfoliate club. Eyes large, round, slightly divided in front. Maxillary palpi sub- cylindric, the last joint obliquely truncate, the labial smaller, subacumi- nate. Prothorax elongate, narrower posteriorly, deeply sulcate, not con- tiguous to the elytra. Scutellum punctiform. Elytra elongate, nearly parallel, ribbed, wider than the prothorax. Legs short ; coxae not con- tiguous ; tibiae spurred, somewhat dilated and more or less toothed externally near the apex ; tarsi slender, hairy beneath, the basal joint subelongate. Presternum prominent, keeled in the middle. Abdominal segments gradually diminishing in size.
Allied to Sosylus, with which it also agrees in habit, but at once distinguished by its triarticulate club and sulcate prothorax. I have not dissected the mouth of my specimen (which I owe to the kindness of Mr. Fry, by whom alone, I believe, it has been taken) ; but the mentum seems to be very small, and attached internally to the large subquadi'ate jugular plate, which M. Lacordaire has, apparently, denominated the "sous-mentorC^ ; the point of insertion of the palpi is, however, not covered by it, but is more than usually obvious.

Prosternmn produced. The first two abdominal segments larger than the others.
Although the second abdominal segment is fully as large as the first, yet, as they exceed the remainder, this genus cannot be placed in any group in which the segments are equal ; otherwise, as its posterior coxae are not contiguous, it might be associated mth Pycnomerus, Ape'istus, &c. In its scaly pubescence it differs from Bothrideres, Sosylm, and all the genera of that group (and the cha- racter, as well as the absence of vestiture, like the sculpture, appear to me to be of importance in this family). The antenna3, described as ten -jointed, may probably have eleven, the club being composed of two, soldered together. In the figure eleven joints are given, but the third should be united with the second.

I believe this genus will be found to include that portion of Erichson's Pycnomerus which is characterized by its eleven-jointed antennae. Dechomus, distinguished by having eight only, has been recently separated by M. Jacquelin du Yal. The two European species, P. terebrans and P. inexsjpectus, with ten joints, will, there- fore, alone represent the true Pycnomeri, The species described below has very slightly impressed antennarj^ grooves, a character which, among the Pycnomerinae, does not appear to be of generic importance.

Hyberis [Colydiidae].
Head short, transverse, immersed in the prothorax nearly to the eyes. Antennae of moderate length, arising beneath the lateral border of the head, moderately thick, ten-jointed, the joints ovate-elongate, setigerous, the first rather incrassated, the third longest, the tenth forming a pyri- form club. Eyes lateral, round, rather prominent. Mentum nearly quadrate. Palpi claviform, terminal joint of the maxillary much larger than the others, shortly ovate, truncate, of the labial oblong-ovate. Prothorax transverse, bisinuated in front, rounded and strongly ser- rated at the side, narrowed behind. Elytra much wider than the pro- thorax, broadly ovate, convex. I^egs moderate ; coxae distant ; femora robust; tibiae fusiform; tarsi short, the basal joint longer than the two following. Abdominal segments nearly equal.
As the only specimen I have seen of this insect belongs to the British Museum, I am unable to give any account of its oral organs ; but there can be no doubt that it is nearly allied to Ajpeistus, and it would therefore be interesting to know if it be

Pharax [Colydiidas].
Head short, transverse, rather widely dilated below the eyes, and deeply inserted in the prothorax. Antennae short, eleven-jointed, the two basal incrassated, and nearly concealed above, the third longest, the rest gradually diminishing in length and becoming transverse, the last two forming a compact ovate club. Eyes small, round. Mentum rounded at the sides and in front. Terminal joint of the maxillary palpi triangular. Prothorax transverse, largely dilated and rounded at the sides, narrowed posteriorly, the disc very convex and irregular. Elytra connate, much broader than the prothorax at the base, short and irregular. Legs moderate ; all the coxre distant ; femora robust ; tibia? fusiform, bordered externally with scale-like hairs ; tarsi short, the basal joint longer than the second or third. Abdominal segments nearly equal.
This genus, in habit like Vlo7iotm, is allied to the last (Rybens)^ from which the eleven -jointed antennse and biarticulate club will at once distinguish it. The description of the mentum and palpi must be received with some hesitation, as they were examined in situ. The two specimens now before me are among those almost inexhaustible

The number of undescribed genera which are almost sure to be found in every extra- European collection that may be formed by an accomplished naturalist, should not be overlooked by those who are inclined to question the necessity of the multiplication of new names.

Head transverse, much narrower than the prothomx and deeply inserted in it, its supra-antennary borders slightly produced. Eyes large, and very rough, from the facets being prolonged into short spines. Antennae short, slender, eleven-jointed, the first and second slightly incrassated, the third longest, the remainder to the ninth gradually decreasing in length, the tenth and eleventh forming an abrupt ovate club. IVIaxillary lobes ciliated, the external sub triangular, the internal narrower. Palpi short, claviform; the terminal joint of the maxillary ovate-cylindrical, of the labial ovate-oblong. Mentmn subquadrate. Labium ti'ans- verse, ciliated anteriorly. Prothorax very transverse, narrowed and sinuated anteriorly, as broad as the elytm at the base.

Abdominal segments gradually decreasing in size.
The widely separated posterior coxae narrow considerably the number of Colydian genera with which Chorites may be compared ; at the same time, although the first abdominal segment is in every way larger than the others, there is not the decided diff'erence we see in Derataphnis, Sosylus, &e. ; and if we exclude these genera.

Although Erichson has characterized Discoloma in very few words, I cannot doubt that the insect described above is correctly referred to that genus, as indeed Mr. Fry had pre^iously suggested to me ; the only difficulty is, that Discoloma is said to have the basal joint of its antennae simple, or not enlarged, which is not the case in the present species. However, the habit of the typical form appears to agree with this, and is so remarkable — resembling some of the Nitidulidoe {Amplwtis for example) — whilst the structure so nearly
I 2

accords with Cerylon, in close proximity to which Erichson has placed the genus, that this discrepancy need not, for the present at least, necessitate the generic separation of the two insects. In addition to Erichson's description, the following generic characters (most of them the same as in Cerylon) may be noticed in D. Fryi : — Eyes narrow, transverse, scarcely prominent; external maxillary lobe long and very slender, ciliated at the apex (inner lobe not seen) ; maxillary palpi short, the first joint very small, the second greatly enlarged, the third siibcyhndrical, the fourth minute, acicu- late ; the labial palpi mth the second joint enlarged, the third shortly conical ; mandibles bidentate at their extremity ; mentum small, quadrate^ labium rounded anteriorly ; tarsi very short, the three basal joints oblique, and hairy beneath.

The few characters which Erichson has given of this genus, its very peculiar habit (resembling an OntJiophilus), combined with the acicular palpi of the Ceryloninae, and its habitat of Brazil, would seem to leave no doubt that the insect described above is correctly referred to Glyptolopus. The antennae, however, are certainly twelve-jointed, while Glyptolopris is said to have onlj- eleven. Has

Mandibles very slender, curved, not toothed. Palpi robust. Prothorax transverse, semicircular, not dilated at the sides. Scutellum rather large, tri- angular. Elytra as broad as the prothorax at the base, gradually rounded at the sides, narrow and flattened posteriorly. Winged. Legs mode- rate ; intermediate coxae not approximate ; tarsi slender, the fourth joint not bilobed.
Although I do not hesitate to refer this most extraordinary insect to the Lampyridae, yet it must be confessed that it is a very aberrant form, and suggests no affinity with any Malacoderm genus that I am acquainted with. Its head (composed, at least externally, almost entirely of eyes, which are constricted in the middle like an hour- glass) is fully exposed; the narrow vertex descends behind the upper portion of the eye, and fills in the space behind and between the constriction, and is prolonged in front to terminate in the labrmn, although, from the presence of numerous coarse hairs, the existence of this organ cannot be positively asserted. The antennae are very short, scarcely extending to the prothorax, and show no traces of being serrated. I am indebted for the only specimen I have seen to Dr. Ernest Adams, of University CoUege, after whom I have named it. The abdomen of the specimen having been cut away, apparently to facilitate (?) the mounting, the number of its segments cannot be ascertained : the abdomen itself, however, appears to have been very small ; the metasternum must have exceeded it in length as well as in breadth.

CoTXJLADEs [Tenebiionidae].
Head subquadrate, exserted, but not constricted behind. Eyes small, lateral, round. Antenna) subnioniliforni, short, thick, veiy hairy, the basal joint longest, the rest to the tenth subequal, very transverse, the eleventh smaller, truncate. Labrum small, rounded anteriorly and ciliated. Mentmii subquadrate, produced at the sides. Labium trans- verse, rounded in front. l*alpi short, clavate, tenninal joint ovate. Prothorax subquadrate, wider anteriorly. Elytra ovate, convex. Legs short; all the tarsal joints, except the last, very short.
To this genus belongs the Tagenia leucospila of Mr. Hope ; the head, however, not contracted behind into a neck, and other cha- racters show that it is veiy distinct from Tac/enia ^Stenosis'] ; at the same time it is difficult to point out a nearer ally. In this and the following genus the intermediate legs appear to be without trochanters.
Cotidades fascicularis. (PI. YII. fig. 5.)
C. niger, rugoso-punctatus ; elytris obsolete albo-fascicidatis.
Hah. Australia (Melbourne).
Dull brownish-black ; head and prothorax covered with large, coarse, nearly confluent pmictiu-es, and sparingly furnished with stift', decum- bent, scaly hairs; elytra coarsely striato-pimctate, each with three indistinct ridges and with eight to ten short fascicles of brownish- white hairs, indeterminately arranged, but sometimes nearly wanting (fi'om abrasion ?) ; claws pale ferruginous ; body beneath strongly punctured. Length 3 lines.
Elascfs [Tenebrionidae].
Head rather elongate, scarcely exserted. Eyes small, lateral, undivided. Antennae short, hairy, eleven-jointed, the first longest, the rest trans- verse and more or less equal, except that the last is smaller than the preceding one. Palpi moderate, filiform, the tenninal joint ovate, sub- acuminate. Mentum transverse, the angles roimded. Labium small, transverse. Prothorax subquadi-ate, irregidar, much broader than the head, projecting in front, and lobed posteriorly, slightly dilated and seiTated at the sides. Scutellum very small, quadrate. Elytra nearly parallel, broader than the prothorax. Leg-s short ; femora and tibiae compressed, the latter ciliated externally ; tarsi very short and slender, the last joint nearly as long as the rest together.

Elascus crassicornis. (PL YII. fig. 7.)
JE. subdepressus, fuscescenti-varius ; antennis medio abriipte incrassatis.
Hab. Australia (Melbom-ne).
Hatlier broadly depressed, covered with coarse, curly, dusky-brown hairs varied with paler or greyish markings ; head and prothorax grey- ish-brown, the latter with foiu' tubercles on its disc and the projecting anterior portion strongly bilobed ; elytra bordered with hooked hairs, with three waved costae on each, tenninating posteriorly in as many tubercles, between which and the apex is another and larger one, a small oblique stripe behind the shoidder and a broad band near the apex ; antennae greyish-brown, the terminal half darker, with the third joint much thicker than the two preceding, the fom-th and succeeding joints gradually diminishing in thickness; legs dark brown; body be- neath pitchy, with yellowish-brown scaly hairs. Length 3 lines.
I have only seen two specimens, both of which were taken by Mr. Bakewell, at Melbourne, under the bark of trees composing a stock-yard fence.
Elascus lunatus. (PL VII. fig. 8.)
K subangustatus, fuscus, nigro-varius ; elytris albo-fasciatis.
Hab. Australia (Melbom-ne).
Rather narrow, slightly depressed, covered with coarse scaly hairs, which are yellowish-grey on the head, but considerably darker on the prothorax and elytra, or nearly black, the latter having three whitish bands (the two anterior crescent-shaped, but sometimes nearly coales- cing, the posterior straight) ; prothorax with four tubercles on its disc, the anterior projecting portion rather broadly bilobed, each lobe form- ing (so to speak) an additional tubercle ; elytra coarsely seriato-punc- tate, each with three costae, the inner nearly obsolete except at the base ; antennae not abruptly thickened in the middle, yellowish varied with dark brown, especially the three terminal joints; legs ferruginous, more or less marked with dark brown ; body beneath covered with greyish-yeUow scaly hairs. Length 2^ lines.
The post-prothoracic lobe is less developed in this species than in the former, or, in other words, it is broader and less abruptly de- fined. The two specimens (also captured by Mr. Bakewell) now before me difier considerably in depth of colour and amount of white on the elytra ; but in this, as in other instances, the pattern is the same.

Doc A LIS [TenebrionidajJ. Head rounded, exserted, the untennarv orbit nearly dividing the eye. Antennj\3 short, covered with numerous small liattish hairs, the first three joints longest, the rest transverse, the tenth larger than the eleventh. Mandibles stout, bifid at the apex. Palpi robust, terminal joint of the maxillary short, stout, of the labial obconic, obtuse j external maxillary lobe short, triangular, fringed, the inner narrow, toothed. Menluni arising within the jugular plate. Prothorax subquadrate, scarcely wider than the head. Elytra ovate-oblong, broader than the prothorax. Legs short, the intennediate furnished with trochantei-s ; coxa) not contiguous; tibife not spurred ; tarsi -with all the joints ex- cept the last very short and fringed with spiny hairs. Prosternal pro- cess quadrate. Mesosternum depressed.
The Tagenia funerosa of the Rev. F. W. Hope is, I think, refer- able to this genus ; and, trusting solely to recollection of his type, now in the Taylor Institute at Oxford, it is very close to, if not identical with, my D. degener ; but without certainty on this point, it is better to assume that they are distinct. The genus seems to be referable to the Scaurina), and, so far as my knowledge of the group extends at present, it might follow Ammopliorus. The struc- ture of the mouth, in reference to what I have called the " jugular plate," but which appears to be the " sous-menton " of M. Lacordaire, is very similar, judging from that author's description, to that of Nyctoporis, which genus immediately precedes Ammopliorus. The larger penultimate joint of the antennae is suggestive in a slight degree of the club of many Colydian genera ; indeed, there are so many points of resemblance between several of the Heteromera and the Colydiidas, as to justify a doubt whether they may not be more than mere analogies.
Docalis exohtus. (PI. VIII. fig. 9.)
/>. oblongo-ovatus, fuscus ; prothorace transverse.
Hah. Australia (Melbourne) j Tasmania.
Oblong-ovate, dark brown, everywhere covered, but not very closely, with semi-erect, stiff black scales (hairs), intermixed, especially on the head and prothorax, with rusty-white ; prothorax slightly broader than long; scutellum roimded behind; elytra co.arsely seriato-piuictate, marked with several slightly elevated longitudinal lines, which are severally crested with a row of whitish scales ; body beneath pimctured, each puncture enclosing a short rusty hair. Length 2 to 3 lines.
For my knowledge of this and the species of the two preceding genera, I am indebted to Robert Bake well, Esq., who informs me that they, and many other insects as well, are found beneath the
122 Mr. E. P. Pascoe on some new or Uttle-hioivn
bark of logs which are piled one on another in the formation of stockades. Few of the many collectors in Australia appear to be aware of the novelties which a careful examination of such localities would afford them.
Docalis degener. D. oblongo-ovatus, praeeedenti angustior, niger ; prothorace eequali. Hah, Tasmania.
Narrower and darker than the last, with the prothorax at least as long as it is broad, the scales whiter and less numerous and the pimc- tures larger, and the longitudinal lines on the elytra more prominent. Leng-th 2 lines.
Sphaegeeis [Tenebrionidse].
Head small, transverse, abruptly contracted below the eyes. Antennae eleven-jointed, very short, gradually increasing in thickness from the third, which is longest, the second minute, the first incrassated. Eyes lateral, very small, round. Labrum naiTow, not covering the man- dibles, which are bifid at the tip. Maxillary lobes narrow, the ter- minal joint of their palpi subsecuriform. Mentimi subcordate, nar- rower behind. Labium bilobed and ciliated anteriorly; labial palpi long, the terminal joint ovate, pointed. Prothorax short, transverse, narrower anteriorly, rounded at the sides. Elytra shortly ovate, very convex. Legs short, more or less covered with spinous hairs j tibiae triangular, strongly spurred, the anterior sinuated externally; tarsi short, the basal joint longer than the second. Prosternum compressed, cariniform.
Closely allied to Mr. White's genus Choerodes (Voyage of the Erebus and Terror, Ins. p. 12. tab. 2. fig. 12), but differs essen- tially in the antennae, Choerodes having {inter alia) a triarticulate club {see PI. V. fig. 10) ; in both, however, they are eleven -jointed.

ec'cond minute, tln> third lon^'-est, the rest more or less moniliform and beeomiiifx «rradiiully thicker upwards. E3X'S lateral, small, round. Maxillary palpi strongly securiform, the labial very short Jind thick. Prothorax narrowi'r than the head, much contracted liehind, Scu- tellum none, l^lytra connate, veiy convex, broadly elliptical. Legs moderate; anterior coxa) globose, not contiguous; tibiae unarmed, hairy at the base internally ; tarsi short, thick, hairy beneath, the basal joint longer than the second, the penultimate bilobed. Prosternum produced, rounded posteriorly, and remote from the mesosternum.
An examination of the mouth might throw some light on the affinities of this very curious little insect ; but as the only specimen I have seen belongs to the British Museum, and moreover is not in very good condition, this cannot be done at present. In habit it resembles the Anthicidae, but the globose anterior coxae separate it from that family ; the bilobed tarsi, an uniLsual character amongst the Tenebrionida3, suggest an analogy, or perhaps an affinity, with Phyinatodes and Phohelius, It is one of the many important cap- tures of Mr. Bates in the valley of the Amazons ; and as that gen- tleman is preparing a series of papers on some of the insects of his extensive collections, it is to be hoped that this and many other curious forms which he possesses will be at no distant date more amply illustrated.

C. niger, nitidus ; prothorace elytrisque tuberculatis, tuberculis setigeris ; tarsis paUidioribus.
Ilab. Brazil (Ega).
Black, shining; head coareely punctured, with scattered, erect, setulose hairs, a semichcular groove between the antennary orbits; prothorax and elytra covered with large tubercular elevations, arranged in rows on the latter, each of which bears a long, erect, setose hau- ; tarsi and base of the tibiae internally with pale silky hairs ; labial and maxiUary palpi at the base pale ferruginous ; antennae setigerous, as long as the head and prothorax together. Length 2 lines.
DiFSACONiA [Tenebrionidae].
Head small, rather narrow and elongate below the eyes, deeply inserted in the prothorax. Eyes transverse, undivided. Antenna rather short, submonilifonn, slightly hairy, the basal joint incrassated, the second very short, the third longest, the remainder gi'adually decreasing in length, but becoming broader and ti'ansverse, to the ninth and tenth, the eleventh subovate. Labrum rounded anteriorly. Maxillary palpi rather long, claviform, the last joint large, ovate, truncate ; the labial very small ; external maxillary lobe broad, strongly ciliated. Mentum

quadrate. Labiimi very transverse. Prothorax narrower than the elytra, transverse, sinuated anteriorly, its surface regular. Elytra rather long, slightly rounded at the sides. Legs moderate ; tibiae bi- calcarate, ciliated externally ; tarsi slender.
Allied to Ulodes, Er., which differs in the following points. In Ulodes the head is short, not being prolonged below the eyes ; the joints of the antennae are subequal and transverse, surrounded by a dense whorl of squamose hairs ; the surface of the prothorax is very irregular ; the elytra are short, and the body generally is covered with short crisp scales. To Ulodes I refer Bolitophagus Saphira, Newm., and Endo^hlosus variicornis, Hope. My genus Byrsax (ante^ p. 42) is also a member of this group of Tenebrionidse (Bolitopha- ginae) : it is true I cannot quite satisfy myself that it is hetero- merous, but I have no doubt a minute basal joint exists; and in other respects it appears to be congeneric with Diaperis horrida, 01. {Askla Jiorrida, Walk.). Tro^v cornutus, Fab., is also referable to Byr'SCLV.
Dipsaconia Bakewellii. (PL VII. fig. 6.)
D. elliptico-ovata, pilosa, fulvo-brunnea ; elytris nigro-variegatis.
Hab. Australia (Melbourne).
Elliptic-ovate, brownish-fulvous, covered with short decumbent hairs, among which others longer, nearly erect and slightly curved, are interspersed ; prothorax nearly as wide as the elytra at the base j scu- tellum rather indistinct, subtriangular ; elytra nearly parallel at the sides, rounded at the apex, striato-punctate, each with three costae, and varied wdth four or five dull-black band-like marks ; antennae brown ; body beneath ferruginous-brown, very sparingly pubescent. Length Sp- lines.
In this and the following species, both of which we owe to Mr. Bakewell's researches, may be noticed, in certain lights, a glowing fiery-red tubercle at the bottom of each elytral puncture.

TiTHAssA [Tenebrionida)].
Head small, exsorted, its antc'rior border incrassated. Antcnnrc stout, modi'rati'ly lon<r, the tirst and second joints scarcely thicker than tlio third, which is longer, the remainder to the eighth short, the last three fonning an oblong, loose, compressed club. Eyes small, lateral, round. Epistome and labrum narrow, not covering the mandibles, the latter broadly eniarginato. Mandibles bifid at the apex ; terminal joint of th(; palpi ovate, subacuminate, the second joint of the labial larger than the third ; maxillary lobes subequal, fringed. Mentum subquadrate. Labium rounded. Prothorax transversely subquadrate, narrower than the elytra, its margins dilated. Elytra large, convex, broadly ovate. Legs small ; cox?e not approximate, the anterior cylindrical, transverse ; tibiae not spurred; tarsi pubescent beneath, the penultimate joint di- lated. Prosteruum pointed behind; mesostemum depressed; post- intercoxal process triangidar.
The majority of the characters of this genus point, as it appears to me, to the Diaperinte, but the differently-formed tarsi and the disproportion between the prothorax and elytra forbid its union with that group. At the same time, the antennae come nearer those of PentaplujUus " in plan " than any other heteromerous genus that I am acquainted with. It seems to be a common Eio insect.

Head moderate, subquadrate. Eyes large, transverse, contiguous to the prothorax. Antennae short, clavifonn, the first joint nearly concealed above by the antennary orbits, the four or five terminal joints com- pressed and, except the last, more or less transverse. Labrum rounded anteriorly. Maxillary palpi with the last joint securiform, the labial ovate, truncate ; maxillary lobes short, strongly ciliated. Mentum subquadrate. Labium slightly expanded at the sides, entire and ciliated in front. Prothorax transverse, nearly as broad as the elytra at the base, rounded at the sides, scarcely emarginate anteriorly. Elytra elongate, their greatest breadth behind the shoulders, slightly curved

This unpublished genus of Dejean's was placed by him nearly at the end of his Tenehrionites, an heterogeneous assemblage, including as it does Melandrya, Pytho, Pezodontus, Camaria, &c. With the last of these genera, however, and with its allies, Chariotlieca must be placed.

In characterizing (Edemutes (ante, p. 51), the semilunar, sulcated anterior portion of the head was described as the epistome, and M. Lacordaire appears to have done the same in his description of Sphce- rotus *. The real epistome, however, is inserted heneath the anterior border, and in Splicer otus curv'ipes is completely hidden by it ; but, on the other hand, it is almost entirely exposed in another common Species, Sphcerotus gravidus. In Omolipus (at least in the species described below ; for the character scarcely seems to be of generic value), the labrum, which is rather strongly developed, also appears to be inserted dii^ectly beneath the anterior border of the head, and the epistome is therefore not apparent. The nearest affinity of Omo- lipus is probably Misolampus, from which, among other characters, the presence of a very distinct scutellum will at once distinguish it. This genus is another exception to the absence of the hook on the internal maxillary lobe, a character which at one time was supposed to distinguish the Helopidae from the Tenebrionidae. Another excep- tional character is the approximation of the base of the labial palpi, which are inserted in front of the broadly transverse, membranous lower lip.

Ovate, dark pitchy-brown, sparin<rly fiiriiislied above with pah- yeUow- ish-green scales; rostrum loiifjer than the head, gibbous bcdow the eyes, and separated from them by a semicircular depression, with a broad longitudinal furrow in the middle; prothorax shortly ovate, closely granulated, and covered with coarse deep punctures ; scutellum none ; elytra very short, pei-pendicularly bent down behind, roughly punctato-granulated, slightly convex in the male, with the posterior angle produced into a long flexible process, flat and depressed in the female, and without any prolongation ; legs moderate, furnished with stiff scattered hairs, the femora orange-red, except at the apex (in the female darker) ; antennae black, shorter than the body, slightly hairy ; body beneath pitchy, coarsely punctured. Length 3^ lines (d)j 8 lines ( $ ).
Blapsilon [Cerambycidae].
Head short, scarcely convex in front. Eyes small, lateral, deeply eraargi- nate. Antennae shorter than the body, sublinear, distant at the base, the first joint thickened, shorter than the third, which is longest, the fom'th moderate, the remainder very short and subequal. Labrum small, slightly emarginate. Mandibles robust. Palpi stout, the terminal joint elongate-ovate, truncate. Mentum very short and transverse. Pro- thorax broader than long, nan*ower in front. Scutellum elongate, pro- duced anteriorly. Elytra ovate, broader than the prothorax at the base, elevated in the middle, and produced at the shoulder into a short, hooked, horizontal process. Legs moderate ; coxae distant ; tarsi short, very slightly dilated. Prostemum received into a notch of the mesosteraum.
The scutellum of this genus is remarkable. It is not only un- usually narrow and somewhat hexagonal in form, but it is projected forwards on the prothorax, which is probably notched for its recep- tion, although this point cannot be ascertained without risk of in- jury to the specimen. BJapsUon must be placed near Tmesisternus.

apex ; antennae as long as the breadth of the head behind, the first joint punctured, the rest glabrous with a few hairs only on the club ; prothorax shining black with the anterior angles obtuse, the sides rounded rapidly to the base, the posterior angle nearly obsolete, covered with oblong punctures, those at the side only granulated ; scutellum transverse, with 6-8 punctures in two rows ; elytra dull black, seriate - punctate, the punctures coarse, oblong, and in double lines, the inter- vals smooth, and slightly elevated ; femora and tibiae simply punctured ; body beneath pitchy black with granulated pimctures. Length 7 lines.
Melamhia memnonia.
M. subelongata, atra ; prothorace transverso, disco subplanato, antice incrassato, basi lata, angulis posticis acutis ; elytris obscure fuscis.
Ilah. Ceylon.
Subelongate, black; head covered with rather closely set, oblong, granulated punctures, mandibles with small simple punctures extend- ing to the bifid apex ; prothorax black, slightly shining, punctured as on the head, but less closely, and the punctures with granulated bases confined to the sides, anterior margin thickened immediately above the vertex, the disk flattened behind the thickened parts, side slightly rounded, then shortly curving inwards, and terminating at a sharp angle in a broad base ; scutellum transverse, with eight or ten scattered punctures ; elytra opake, nearly black, with a slight chestnut-brown tinge, punctured in double rows, the outer row with its punctures about a third or a fourth of the size of the inner, which latter are more or less impressed on the side of the raised lines between the rows ; legs pitchy, the femora and tibiae punctured ; body beneath, under side of the mandibles, and palpi reddish-pitchy, the former with scattered punctures, each nearly entirely occupied by a smooth granule. Length 6 lines.
In the form of the prothorax this species approaches M. gigas, Fab., and apparently also M. striata, Or., both from Senegal ; but the former is larger and more robust, with bluish-black elytra, &c., and the second is distinguished by its more punctured and remark- ably transverse scutellum, &c. 31. crenicollis, Guer., from India, seems to be a smaller species with a differently shaped prothorax, with its sides sufficiently crenated to suggest the specific name.
Melamhia funehris.
M. subelongata, obscure atra ; prothorace transverso, disco leviter convexo, basi sublata, angulis posticis acutis.
Hah. Cambodia.

not iu tlio least tliickt'iicd ; elytra with llie lines between each double row ot'punetures more raised, the punctures (more nearly equal in size) and the lines themselves gradually disappiMiring towards the shoulder; colour a didl black, without any tingo of brown.
It is quite possible that this may be only a local variety ; but, with tlie members of a genus so closely allied as they ai'c in Melambia, this cannot be assumed until we obtain intermediate forms.

Hab. Sydney.
Ferruginous brown, covered with short, dark, setulose hairs ; head rather exserted, the vertex somewhat depressed; eyes dark brown; antennae longer than the body, with a shght greyish pubescence, the first joint nearly as long as the four next together; prothorax rather broadly elongate, covered with numerous large shallow punctures, the sides denticulate, the anterior angle occupied by a strong triangidar tooth ; scutellum transversely pentagonal ; elytra clo.sely punctate- striate, becoming gi'adually darker towards the sides ; legs pale fen-u- ginous ; body beneath dull ferruginous, closely punctm-ed. Length 4 lines.
Brontes nigricans.
B. fuscus; prothorace lateribus denticulatis, dente antico incrassato; elytris striato-punctatis, nigricantibus.
Hab. Queensland (Moreton Bay).
Dark ferruginous brown, covered with short, black, setulose hairs ; head slightly exserted ; eyes dark brown ; antennae longer than the body, the first joint shorter than the four next together; prothorax broadly elongate, rugose, slightly punctated, the sides equally denticu- late, the anterior angle occupied by a moderately thickened tooth ; scutellmn transversely pentagonal ; elytra punctate-striate, of a uniform dark brown ; legs feiTuginous ; body beneath dull ferruginous, closely punctured. Length 4 lines.
From Brontes denticulatus, F. Smith (also from Australia), the two species described above differ in the comparatively elongate, not transverse, prothorax and other characters. Brontes miJitari.^, Er., is smaller and less robust, narrower prothorax, differently coloured, differently punctured, &c.

Ino [Cucujidae]. Laporte de Castelnau, Etud. Entom. p. 135.
Ino ephijppiata. (PI. XYI. fig. 9.) /. nigTa, nitida; elytris disco pallide flavescente, abdominis segnienta
tria ultima liaiid obtegentibus. Hah. Dorey (New Guinea).
Deep glossy black ; bead and protborax about equal in breadth, finely punctured, the latter very mucb contracted at the base ; antennae balf as long as the body, black, the basal joints paler ; palpi pale brown ; scutellum black, transversely ovate; elytra narrowed at the base, gradually widening posteriorly, where they are as broad as long, the sides straight, the disk with a large pale-yellow spot occuppng nearly the whole of the base, except the shoulder, and expanding below the middle towards the side ; part of the third and fourth and fifth abdo- minal segments dull black, not covered by the elytra ; legs light glossy- brown, tarsi testaceous ; body beneath paler. Length 1| line.
Ino trepida.
I. fusca, nitida ; elytris singulis flavescente unimaculatis, abdominis seg- menta quatuor ultima baud obtegentibus.
Hah. Dorey (New Guinea).
Dark olivaceous brown, shining ; head and prothorax equal in breadth, finely punctured ; antennae about one-third the length of the body, the two basal joints yellow, the remainder black ; scutellum and el}i:ra as in the last, but the yellow spot on the latter is smaller, nearly round, and situated below the middle and towards the outer margin ; abdo- men dark brown, shining, the last four segments not covered by the elytra ; legs olivaceous brown, the tarsi paler, inclining to testaceous. Length 1| line.
Ino is a very singular genus, and was placed by M. de Castelnau among the Staphylinidse, after Antliohium. The species described by him (J. picta) from Madagascar has slightly elevated lines on the elytra, and it is possible that the two described above may hereafter form another genus.
Phenace [Dasytidae]. Head short, rounded in front, the epistome and lip concealed beneath its margin. Eyes large, prominent, entire. Antennae filifoim, distant, arising below the eyes, the first joint rather short, obconic, the second very short, the remainder to the tenth longer and subequal, the last longest of all. Maxillary palpi long, the terminal joint fusiform. Mandibles long, slender. Prothorax rounded at the sides. Elytra broader than the prothorax, elongate. Legs slender ; tibiae spurred ; tarsi very long, the basal joint longer than the second.
In general appearance this genus has a wonderfully striking re-

semblance to sonic of the (Edemeridoc ; itH very distinctly five-jointed tarsi, however, independently of otlier characters, show at once that it can have nothing to do with that family. But there can be no hesita- tion, I think, in referring it to the Dasytida^, notwithstanding tho structure of the mouth and the presence of two well-marked spurs to the tibiae : in regard to the first, the lip and epistomo are so com- pletely hidden by the scarcely prolonged anterior margin of tho head, that, Avithout dissection, their existence can only bo assumed ; be- tween tliis margin and the mandibles there intervenes a sort of cavity, and the latter, not being covered in the usual way by the lij), arc fully exposed almost to their base. My specimen, which is unfortunately, I believe, unique, was taken by the well-known traveller Anderson, in Southern Africa, in the country near Lake N'Gami.
Phenace oedemerina. (PI. XVI. fig. 6.) P. gracilis, fuscescens, parce pilosa ; scutello elytrisque pallidioribus. Hah. N'Gami.
Slender, dark olivaceous brown, sparsely clothed with rather long, pale-gi'eyish hairs ; head and prothorax shining, dark brown ; scutelluiu elongate, rounded below, a depressed longitudinal line in the middle ; elytra narrow, elongate, nearly parallel, the shoidders rather promin«'ut, substriate, olive-bro\A-n, paler as it recedes from the base ; mandibles bright ferruginous ; legs reddish brown ; body beneath dark brown, hairy. Length 3^ lines.
OcnoTYEA [Lampyridae].
Head partially exposed, short, broad in front. Eyes very large, contiguous beneath, constricted behind. Antennas very short, 12-jointed, the two basal thickened, the rest sen-ated. Prothorax transverse, naiTOwer than the head. Elytra broader than the prothorax, subparallel, shorter
^ than the abdomen. Legs moderately short, all the cox£E nearly con- tiguous; tarsi slender. Abdomen eight-jomted in the male, the joints gradually decreasing in breadth to the apex.
This genus is allied to Dioptoma (ante, p. 118), and the nearest affinity of the two is apparently with Luciola, Lap. {^Colophotia, Dej.). In the only example I have seen of the former the abdomen has been removed, but, judging it from what wo now see of this, it is probably also exserted, with the same number of segments — the normal number, in fact, in the males. The females of both are un- known.
Oeliotyra semiusta. (PI. XVI. fig. 7.) (). pallide fulva ; capite prothoraceque piceo-fuscescentibus. /frt6. India (Malabar).
Pale fulvous yellow, very sparsely covered with greyish nppressod
hairs ; head pitchy-browni, concave between the eyes, epistome with
324 Mr. F. P. Pascoe on some new or liUle-'known
stiff gi'eyish hairs; antennae not extending beyond the eyes, pale yellow, strongly serrated, broadest in the middle ; eyes dark browTi, shining ; prothorax light pitchy brown, darker on the disk ; scutellum rather large, triangular ; elytra about twice the length of the head and body together, depressed, and almost concave posteriorly, with elevated nervures in the middle, ^. e. not extending to the base or apex ; legs clothed with stiff hairs, particularly on the tibiae ; abdomen dull whitish yellow. Length 4 lines.
In the Plate the figure of this species is longer than it ought to be.
Ethas [Tenebrionidae]. Head elongate, broader than the prothorax, rounded and dilated anteriorly, naiTowed into a neck behind. Eyes remote from the prothorax, lateral, partially divided posteriorly. Mentum somewhat pentagonal, narrow at the base, concealing the labium. Maxillary palpi robust, the ter- minal joint subcylindric, of the labial ovular. Antennae stout, eleven- jointed, the first largest, the second shorter than the third, which, with the remainder to the tenth inclusive, are ti\insverse and cup-shaped, the eleventh small, shortly cylindric. Prothorax sulcated, subquadraugular, broadest in front, the anterior angles rounded, the sides keeled. Elytra elongate-ovate, wider than the prothorax, ribbed. Legs robust ; femora slightly clavate ; tibiae not spurred ; tarsi ciliated beneath ; presternum produced, rounded anteriorly.
The ribbed prothorax and elytra will at once distinguish this genus from Stenosis, which has exactly the same habit. The structure of the mouth varies a little from that genus, in Ethas the large angular mentum filling up more of the oral cavity, and entirely concealing the labium.
Ethas carbonarius. (PI. XVI. fig. 2.)1
E. niger, subnitidus ; prothorace leviter trisulcato ; elytris singulis lineis quinque elevatis instructis.
Hab. Malabar.
Punctured, black, slightly shining ; head convex between the eyes, with three rather shallow grooves, and on each side a somewhat deeper groove in which the eye is placed ; prothorax a little naiTower than the head, marked witli three lightly impressed lines or gi'ooves, the spaces between, especially the two middle, slightly elevated and convex ; scu- tellum punctiform ; elytra scarcely wider than the prothorax at its base, each with five narrow elevated lines rather thickened at the suture, but scarcely forming another ; legs slightly pitchy ; palpi ferru- ginous ; body beneath black, shining, sparingly punctured.

ArosYLA [Tenebrionida).]
Head convex and subtriangular in front, slightly elongated behind the eyes. Antennse short, eleven -jointed, gi*adually increasing from the base, the first joint partially concealed by the antennarj' orbit. Eyes large, round, entire. Epistome and lip short, very transverse. Palpi with the terminal joint narrowly triangular. Mentum transverse. Prothorax subcordate, scarcely longer than broad. El}^ra narrow, sub- parallel. Legs moderate ; anterior coxa) large, subcylindrical, greatly exserted ; tibia) spined ; tarsi slender.
But for the large and greatly exserted anterior coxsd, I should not hesitate to place this genus near Calcar, although the antcnnary orbit is so contracted as to leave the eye perfectly free, and the epistome, although short, is of great breadth and apparently distinct from the front. Whatever its affinities maybe, I cannot myself see, at present, that it can be better placed than near Calcar and Boros.

Elytra subdepressed, carinated, scarcely broader than the prothorax, and slightly rounded at the side. Legs rough, moderately robust; tibiae fusiform; tarsi narrow; the claw-joint as long as the rest together ; pro- and mesostema simple ; post-intercoxal plate broadly truncate anteriorly.
ITotwithstanding the small size of this insect compared with Zoplierus and Nosoderma, there can be Httle hesitation, I think, in placing it near those anomalous genera. Judging from the exami- nation of the oral organs made in situ, they appear to offer only a slight modification of those of Nosoderma, the mentum, however, being considerably larger and in great measure hiding the palpi and base of the maxillge, the part between its lateral margin and the insertion of the antenna offering a deep canity, as in that genus, for the reception of its basal joints when that organ is in repose. The propectus has no antennary canal at its side as in Zoplierus, in this respect agreeing better with Nosoderma ; on the other hand, the latter has only a ten-jointed antenna, but this is again modified by the fact that N. ohcordatum, Kirby, has eleven.

This species differs considerably in habit from C. ChildreniijW est., and in that respect bears a marked resemblance to Thecaceriis hino- dosits, Lap., belonging to the same family. It may be necessary eventually to propose a new genus for its reception.

Probably most akin to 0. iopterus, Westw., but is narrower, with the prothorax more convex, etc. In C. iopterus, too, the prothorax is a dark metaUic green, and the elytra a very deep pui-ple with violet reflections, particularly at the sides.

Ovate, convex ; bead and protborax smootb, glossy black, very finely punctured ; scutelluni small, triangular ; elytra pale ferruginous with a tinge of grey, covered vritb irregular lines of black tubercles wliicli, under the lens, are seen to be composed of smaller ones (from 2-10)^; amongst these, in the intervals, a few deeply impressed punctures j legs bright reddish-feiTuginous, anterior and intermediate tibi?e with a small rounded tooth near the extremity internally ; antennae at the base and palpi ferruginous; body beneath dark brown, coarsely punctured. Length 4 lines.
This very interesting and distinct species agrees generically, ex- cept as regards the mouth, which has not been examined, with 0. picipes, save in the toothed tibiae, which in this instance can only be considered of secondary importance. Both species have more or less of a gloss, which has the appearance of being due to varnish ; the black shining prothorax of the present, however, contrasted with the elytra, is very marked, and recalls many Adesmice, to which also it is very similar in form. A single specimen sent by Mr. Thwaites from Ceylon is in my collection.
OzoTYPTjs [Helopidae].
Characters nearly as in Osdara, Walker*, but differs in the epi- stome not being separated from the front by any groove, by the absence of the scutellum, by the form of the tibiae, wliich are fusi- form and attenuated most at the extremity, and by the shortness of the tarsi, the claw-joint being as long as the rest together. As secondary characters, the form is narrower and more convex, the antennae shorter, and the prothorax gibbons anteriorly. As in Osdara, the prosternum has a sharp-keeled process which is received into a corresponding notch of the mcsosternnm, and the intercoxal plate is broad and rounded anteriorly. The same varnished appear- ance is also as noticeable, but only on the elytra. In Ozotypus the tubercles which cover the upper surface are smaller, more regularly arranged, and each tipped with a short curved hair, which is not the case in Osdara. In both genera the tarsi are all nearly of equal

On a superficial examination this might be taken for a small variety of the above ; but in addition to the distinctions noted in the description, it may also be observed that the spots in this species are much larger and form a less numerous series along the sutiu-e. Mere colour, in the Anthribidse, is not to be depended on unless ac- companied by a certain variation of pattern, as is the case in this instance.

Head small, not contracted below the eyes, rostnmi very short. An- tenna? 12-joiuted; verj^ slender, much longer than the body, arising from a cavity beneath and a little in front of the eye, the first joint swollen at the base, gradually diminishing upwards, and terminated in a truncated apex, the second as long as the first, but slenderer and obconic, the remainder to the eighth inclusive subequal, filiform, their apices more or less tumid, the apical third of the ninth and three ter- minal joints forming an oblong slender club. Eyes large, lateral, deeply emarginate beneath. Antennary cavity gi-ooved above. Epistome and lip forming together a small triangle covering the centre of the man- dibles. Palpi filiform. Prothorax convex, rounded anteriorly, as wide as the elytra at the base, the carina immediately in contact with the base at the middle, but slightly and gradually diverging towards the side, fonning a sharp angle at its flexm*e, then continued to half the length of the prothorax, where it suddenly ceases. Elytra convex, not gibbous at the base. Legs of moderate length, first tarsal joint elongate.
The insect which has served for the above generic description is exceedingly like Frotcedus moerens, Pasc* On examination, how- ever, they will be found to be not oven gcncrically identical, the twelve-jointed antennae and its club, composed not of three only ]>ut also by part of a fourth joint, being, I believe, unparalleled among the Anthribidae, and the emarginate eye and tho position of the abbre- viated carina being quite different in ProtcEdus. I do not here more than allude to the enormous size of the two intermediate tarsal joints, as it is just possible that that miiy be only a sexual character. The

emargination of the eye corresponds to a kind of groove in the upper portion of the antennary cavity, and is obviously intended to allow the antennas to be thrown well back ; this structure does not exist in Protcedus. Another peculiarity is the form of the basal antennary joint, which has a pyriform shape, but with the small end at the apex, which is the reverse of what generally occurs ; but some slight approach to this is made in Protcedus, where the greatest diameter is in the middle.

Hab. New Guinea (Mysol).
Elongate-ovate, somewhat sparsely covered with dull black, varied with white, coarsish, slightly curved hairs ; head with the pubescence nearly entirely white ; prothorax with two large black patches on the disk, divided by a very narrow median line, and two smaller ones on each side ; scuteUum rounded below, very indistinct ; elytra obsoletely punctate-striate, the sides and middle black, the basal and apical por- tions white with a few oblong black spots ; pygidium white ; antennae dark brown, paler at the base ; eyes and mandibles black ; maxillae, palpi, and labrum rufous ; body beneath and legs white. Length 2i Unes.
Owing to the somewhat sparse pubescence, the darker ground is seen beneath the white hairs, thus giving them a pale-ashy hue. The appearance of the markings seems to show that the proportion of the two colours may vary.
PicENiA [Anthribidse].
Head rather broad in front, the rostrum very short, slightly emarginate at the apex for the insertion of the small epistome and lip. Antennae short, eleven-jointed, arising from a cavity beneath the rostrum and close to the eye, the first two joints ovate, thickened, the remainder to the eighth inclusive more or less conic, the last three fonning an ovate, compact, depressed club. Eyes large, round, nearly entire. Palpi slender, hairy, the last joint of the maxillary fusiform. Prothorax transverse, roimded in front and at the sides, the carina basal, and terminating close to the anterior border of the prothorax. Elytra short, convex, parallel to the base of the prothorax. Pygidium small, narrow. Legs rather short. Tarsi short, the basal joint scarcely larger than the inter- mediate two. Claws strongly toothed at the base.

Narrow, subcylindrical, black, covered with a short, thin, greyish pile ; head rather short, narrowed below the eyes, the vertex length- ened ; lip and epistome small ; mandibles black, palpi ferruginous ; eyes (for Niphona) large, black ; antennae shorter than the body ; pro- thorax about equal in length and breadth, constricted anteriorly, the lateral tubercle obtuse, with an indeterminate base ; the disk deeply trisulcate, with three or four shorter sulci on each side ; scutellum very transverse j elytra coarsely and remotely punctured, a little broader than the prothorax at the base, gradually tapering in nearly a straight line to the apex, which is shortly divaricate and very deeply emarginate, with the two apiculi formed by the emargination nearly equal in size and much produced, the base with two short crests, the inner pilose, at the apical third an oblique indistinct huffish patch ; legs and body beneath covered with long greyish hairs. Length 8 lines.
At first sight this species might be readily taken for N. FercUnandiy Paiva ; they are, however, abundantly distinct. Touching only a few characters, it may be remarked that the shorter head and larger eye brings this latter organ in pretty close approximation to the base of the mandibles ; the palpi ferruginous, not pitchy black ; on the prothorax the sulcations are deeper, and the two central elevated lines are entire ; the elytra are longer and narrower, the apex shortly divaricate, the emargination very considerably broader and deeper, and the inner as well as the outer apieulus equally prominent and pronounced (in N. Ferclinandi, the inner apieulus is sloped away obliquely^ ; there are also the two crests at the base, and the patch posteriorly on the elytra, no trace of either of which exists in N. Ferdinandi. Numerous specimens of both species have been re- ceived from M. Mouhot.

Subcyliudrieal, black, covered with a short, very pale ashy pile, varied with light fulvous, and spotted with coarse black punctures; head rather narrow^, the vertex very convex ; antennae nearly equal in both sexes, not so long as the body, dark brown, not spotted, and very slightly ciliated beneath ; prothorax nearly equal in length and breadth, the anterior margin scarcely narrower than the posterior, the side a little rounded, although irregularly, the disk with the two usual shallow transverse depressions; scutellum subtriangular, rounded posteriorly; elytra subparallel, the apex entire, several black shining granules arranged in irregular rows, and extending to near the apex, two white irregular spots on each side partially margined with dark brown ; legs and body beneath covered with a similar varied pile ; the second abdo- minal segment in the male larger than in the female, and densely covered w^th short erect bail's. Length 8 lines.
A more cylindrical species than most others of this genus, in general colour approaching S. fronticornisy Fab. ; but the two white spots on the sides of the elytra will readily distinguish it. The peculiar structure of the second abdominal segment is very rarely met vdih. among the Longicoms, and appears to be confined to the males. There is nothing to distinguish St/mpJu/Ictts from Rlujtiphora, Serv., except that the latter has not the lateral tooth on the protho- rax, which generally characterizes the former ; the last joint of the antennse, ^'apice repente curvato,^^ which Newman gives as a character, is only found in two or three species. How Pcnthea, Lap., is to be distinguished I don't know ; it is a stouter form, with shorter and more robust legs, than either Symphyletes or lihyt'iphora. My Pentheu conferta (Am), from its toothed mesosternum and absence of an ten - nary tubercles, must be excluded from the genus. Perhaps it should be placed near Coptops, Serv.

Rather naiTow, dark olive, shuiing, with a very thin, scarcely notice- able pubescence, irregularly and coarsely punctured ; head rather small, a deeply impressed line between the eyes; antennas longer than the body, a little shorter in the female, brown, ciliated beneath ; prothorax nearly as broad as long, the anterior margin narrower than the posterior, the sides scarcely rounded, the disk slightly sulcated with three indi- stinct, interrupted, yellowish bands ; scutellum transverse, rounded posteriorly ; elytra broadest at the shoulder, gradually tapering to the apex, which is sinuated ^dth a short process on each side, almost free from pubescence, except the small yellowish tufts which dot their surface; legs dark olive; body beneath with the pile pale greyish, slightly clouded with buff. Length 6 lines.
A rather common species in collections, and having apparently a wide geographic range. Its nearest affinity is with S. albo-cinctus, Don. ; but, in addition to other characters, it wants the white band at the sides of the elytra. The females of Symphyletes appear to have a longitudinal impressed line in the middle of the last abdominal segment.

Pitchy-black, with a short palo-nr^'vish (or inclining to yellow) pil<j sprinkled with numerous small black spots; head rather broad in front, the spots irrcprular and confused ; prothorax subtransverse, with three obtuse tubercles on the disk (2.1), the posterior divided by a deeply impressed lon«ritudinal line, the two lat<^'ral teetii very distinct; scu- tellum j.Teyish ; elytra rather short, broadest at the shoulders, slifxhtly depressed behind the scutellum, clothed with a pali-{rreyish pile, slightly mottled with a darker grey, and thickly sprinkled with small black spots, which are formed almost entirely by the pimctures ; an- tennre scarcely longer than the body, the basal joint prejish, spotted with black, the rest black, except the second and bases of the succeeding ones to the ninth inclusive which are ashy-white ; eyes and mandibles dark brown ; legs grejdsh, spotted vai\\ black, the tarsi black, the two basal joints white ; body beneath covered with a coarse greyish pile, the sides of the abdomen spotted -with black. Length 10 lines.
The difference between this species and the last is greater than might be imagined from a comparison of the two descriptions, but it may be rendered more obyious by remarking that, while the spots are larger in A. pardaJis,thcy have invariably around the puncture, which forms the centre of each, a circle of black pile, and that these spots often become confluent, having a more or less patchy appearance ; but in A. vomicosa the spots are confined chiefly to the punctures, which then almost entirely constitute the spots ; the two basal joints of the tarsi, nearly of a pure white, offer a remarkable contrast to the deep black of the remainder.
From Abryna, as originally proposed by Mr. Newman, I think it will be necessary to separate those species which approach Dorcadion in fonn and, except veiy partially in one or two of them, in the total absence of pubescence. For these I propose the terra ''Apro- phata," with the following characters : —
Apbophata.
Head rounded, not dilated below the eyes in the male, the vertex and front very convex. Eyes deeply emarginate. Antennjc scarcely longer than the body, not arising from tubercles, the basal joint short, slightly incrassated upwards, the third joint longest, the fourth nearly as long, the remainder shorter and subequal. Prothorax more or less quadrate.
342 Mr. F. P. Pascoe on some neiv or little-hnown
Elytra short, ovate. Legs short, robust. Prostemiim slightly produced posteriorly ; mesosternum with a corresponding process anteriorly. Ex- ternal angle of the anterior cotyloid canities very large.
The principal points which distinguish Ahryna from Aprophata are the rounded head, especially convex in front and on the vertex, the ovate elytra, and the large angulation of the anterior cotyloid cavities; but the habit is so very distinct that it would be doing violence to aU our ordinary notions of generic identity to keep them together, although, it must be confessed, the technical characters are not very important, and perhaps rather questions of degree. I have, however, repeatedly compared aU the species one with another, and I find every character, so far as they can be ascertained without dissection, usually considered of generic importance, and not men- tioned above, more or less variable. The species of Aprophata are excessively rare in collections, very little known, are natives of the Philippine Islands, and have all been described by Mr. Newman in a work which is now very scarce (the * Entomologist '). The follow- ing dignoses of the three species may therefore be useful : —
Aprophata eximia. A. viridi-metallica, nitidissima ; prothorace elytrisque
maculis piligeris griseis omatis. Aprophata fausta. A. nigro-chalybeata, nitidissima ; elytris cyaneo-me-
tallicis, immaculatis. Aprophata 7iotha. A. nigra, subnitida ; sternorum lateribus abdominisque
segmento basali margine hirsutis, ferrugineo-fulvis.
The last species has sometimes a slightly purplish tint, and has been recently received from Manilla (v{a Germany), ticketed "Doliops, n. s." In this species, too, the two prothoracic tubercles are wanting.
Meton [Lamiidae].
Head subquadrate in front. Antennae setaceous, longer than the body, arising from two diverging tubercles, the basal joint rather short, gra- dually thicker towards the apex, the third and fourth equal and longest, the rest more or less equal. Eyes small, deeply emarginate. Lip nar- rower than the epistome. Palpi small, slender, the terminal joint elongate-ovate. Prothorax nearly equal in length and breadth; a short, strong tooth at the side, with small tubercles above. Elytra wider than the prothorax, the sides subparallel, the base more or less crested. Legs robust; tibiae clavate; tarsi straight, the distal end thickened and covered with short hairs ; tarsi narrow, the joints trans- verse, except the basal of the intermediate and posterior, which are triangular; claw-joint moderate; pro- and mesosterna simple.

Dark browii, covered with a fine gi'eyish pile, varied with fulvous j head narrow, elongate, with a deeply impressed longitudinal line ex- tending from the epistome to the prothorax ; eyes large ; antenna more than three times as long as the body, arising from two approximate nearly erect tubercles ; lip and epistome short ; prothorax about equal in length and breadth, narrowed anteriorly, swelling out considerably at the side, and armed with a small but very distinct tubercle, the disk with a slightly impressed longitudinal line ; scutellum rounded poste- riorly, hairy, the centre glabrous ; elytra rather elongate, subtrigonate, rounded at the apex, granulated at the base, indistinctly punctured, sprinkled with fulvous, behind the middle a small black spot on each ; body beneath dull brown ; legs elongate, especially the anterior pair, which have also their tibise seiTated internally, and armed near the extremity with a short spine, the two basal joints of the tai-si of the same pair dilated at the sides. Length 17 lines.
The above description is cbawn up from a remarkably fine male, with the antennae alone four and a quarter inches long. The female has a smaller prothorax, nearly parallel elytra, shorter legs, and an- tennae not more than half as long again as the body. It is allied to M. Alcanor, Newm., hipunctatus. 8chon., and fulvo -irroratus, Blount, all of ;which are referable to M. J. Thomson's IViamses, a genus which I have not adopted, inasmuch as the single character which separates it from Monohammm — the spined protibia) of the male — is so graduated that in some species, plorator, AnUnor, etc. for examjde, it is difficult to decide if the little callus, which represents the spine, is sufficient to constitute it a Rhanises. The habit, too, is just as variable as in Monohamim(s.

Head narrow, quadrate in front. Antennae longer than the bodj; setaceou8> arising from two approximate tubercles, the basal joint elongate, nearly cylindrical, the third longest, the remainder gradually decreasing to the tenth, the eleventh as long, or a little longer.

Prothorax small, trans- verse, narrow in front, gradually expanding into a strong spine, at the side, near the base ; the spines more or less connected by a transverse ridge, contracted at the base. Elytra trigonate, convex. Legs short; tarsi narrow, the basal joint scarcely longer than the second, claw-joint elongate. Prostemum simple, slightly compressed j mesosternum pro- duced anteriorly.
