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." 38 Mr. F.

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.

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. 40 Mr. F. P. Pascoe on some new or little-hiown 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 rufescentibus. Hab. Borneo (Sarawak). Ovate, shining brownish-black, covered with scattered long black setose hairs ; prothorax sparingly punctured ; scutellum triangular ; elytra strongly punctured ; legs brownish-ferruginous.

Shortly ovate, dark brown, with long setose hairs, strongly punctured above ; scutellum subcordate ; legs reddish-ferruginous. Length 1^ line. Broader and more rounded at the apex of the elytra than any of its congeners, and proportionably shorter. 42 Mr. F. P. Pascoe on some neiv or llttle-hiown 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*.

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. Idgia [Telephoridae]. Laporte de Castelnau, in Silberm. Rev. Ent. iv. p. 27.

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 Genera and Species of ColeopttTu. 47 disappear from pliysicul ciiuses alone, just n8 we Hnd certain apeeies of Heniipteru beeominj>' a})terous in cold localities or in very cold seasons. 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. Connodes Dai^nii. (PI. II. fig. 8.)

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.

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.

Length 5 lines. 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. Legs rather short ; an- terior femora strongly toothed ; tibiae slightly curved ; tarsi very short, the last joint longer than the rest together. Prostemum received in a notch of the mesostemum.

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.

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. Ischalia hidigacea. (PI. III. fig. 6.)

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.

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- 62 Mr. F. P. Pascoe on some new or little-hnoiun 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. DinorJiopala spinosa. (PI. III. fig. 2.)

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.

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.

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 h2 100 Mr. F. P. Pascoe on some yiew or Tittle-htioivn into which M. Lacordaire divides them, the present genus must be arranged in the same group with Trogosita proper.

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. JDistaphyla mammillayns. (PI.

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. 106 Mr. F. P.

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. Genera and iSjnciis 0/ Coleoplora. 107 Le)nmis aelalns. (1*1. \'lll. fig. 3.)

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. Ethelema liwtuosa. (PI. VIII. fig. 6.) K oblonga, hirta, nigTa, flavescenti-varia ; prothoracis marginibus den- ticulatis, setosis. Hab. Brazil (Rio ; Para). Oblong, closely covered above with short scale-like black hairs, many of which are curved backwards, more or less varied with pale yellowish or white ; head not wider than the prothorax, a transverse depression in front below the peduncles ; prothorax scarcely narrower than the el}i;ra, except at the base, the margins denticidate, each denticulation -wath a short cm-ved hair arising from its apex ; scuteUum very transverse ; elytra regular, punctate-striate, the stria3 rather remote, tlie patches of 108 Mr. F.

D. elongato-ovatus, fuscus ; prothorace elytrisque costatis, costis ferru- gineo-hirtis. Hab. New Guinea (Dorey). Elongate-ovate, dark brown, with stout, stiff, dilated, pale rusty hairs (or scales), which are chiefly confined to costse and other elevations on the upper surface ; head small, partially reti'acted in repose ; pro thorax with two waved grooves on each side, the outer smallest, and fringed with stiff hairs ; scutellum scarcely visible ; elytra punctato-sulcate, the costse between them closely covered with stift' hairs ; body beneath coarsely punctured, with a setaceous hair in the centre of each ; palpi ferruginous. Length 5 lines. 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. BoTHEiDERES [Colydiidse]. Bothrideres succineus. (PI. V. fig. 3.) B. niger ; prothoracis angulis anticis subacutis, ecostatis ; elytris striatis, tuberculatis, medio succineo-granulatis. Hah. Brazil (Rio ; Para).

B. niger, latior ; prothoracis angulis anticis productis, utrinque tricostatis. Hah. Brazil (Sautarem). Wider than the last, black, opake ; head rather coarsely and deeply punctured ; prothorax less coarsely punctured, rather wider than long, emarginate in front to receive the head, its anterior angles slightly produced, with three strong ribs on each side, the inner occupying the anterior half only, the outer tenninating in the anterior angle, the disc largely impressed with a bilobed protuberance in the centre, and opening out behind into a deep channel, which is bounded on each side by an oblique protuberance ; elytra broader than the prothorax, strongly ribbed, the interstices with shallow, somewhat remote punctures, the ribs seven on each elytron, the external and the two gutm-al ones less marked than the others ; antennae not longer than the breadth of the head ; palpi ferruginous ; body beneath remotely punctured.

S. niger, subnitidus ; prothorace medio lineolato ; elytris apice obtusis, in singulo quadrisulcatis. Hub. Brazil (Para). Black and slightly shining ; head finely punctured, regular, a little convex in front ; prothorax oblongo-ovate, twice as long as the head, finely punctured, a very delicately elevated line along the middle, ter- minating posteriorly between two short linear impressions ; scutellum verj' naiTow ; elytra nearly parallel, obtuse at the apex, each with five elevated costre having between them four broad deep gi'ooves, the two 110 Mr. F.

Length 4 lines. 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. Anarmostes sculptilis. (PI. YIII. fig. 8.) A. elongatus, piceo-fusous ; pedibus rufo-piceis. Hub. Brazil (Rio). Elongate, dark pitchy-brown ; head and prothorax covered with numerous impressed punctures, with a very short hair-like point in the centre of each, the latter with five deep longitudinal grooves ; scutel- lum hollowed out in the middle ; elytra about three times the length of the prothorax, each with five strongly marked costae, the inten^als with a double row of elongated pimctures, giving the spaces between them a granulated appearance ; antennae much shorter than the pro- thorax, yellowish-red ; legs dark pitchy-red ; tibiae finely ciliated and armed externally at the base with three or four teeth ; body beneath coarsely punctured, the abdominal segments with numerous fine, longi- tudinal, iDut more or less interrupted lines. Length 4^ lines. AspROTERA [Colydiidae]. Head rather narrow, depressed, slightly expanded at the sides over the antennae. Eyes large, round, with a deep antennary gToove beneath. Antennae short, ten-jointed, the first two incrassated, the remainder Genera and ^^)^rvV. \vc arc reduced to I't/aiumerus, Apeistus, itc.

Length 2^- lines. There is a second species ? in my collection, also from Borneo ; but, except in its much smaller size (about 1| lino long), and a few black scales being interspersed among the others, there is little to distinguish it. DiscoLOMA [Colydiidae]. Erichson, Natur. der Ins. Deutschl. iii. p. 292. Discoloma Fryi. (PI. VII. fig. 2.) D. piceo-ferruginea vel testacea, pubescens ; elytris parce punctatis ; an- tennis, palpis pedibusque dilutioribus. Hah. Brazil (Rio). Pitchy-ferruginous, in some specimens testaceous, sparingly pubes- cent ; head rather closely punctured, inserted in a deep emargination of the prothorax ; prothorax very transverse, nearly twice as broad as long, very finely punctured, the margins gradually but strongly dilated, with its anterior angle rounded; scutellum small; elytra rather broader than long, and as wide as the prothorax at the base, the disc with several rather large, remote punctures, with a broad and strongly- marked margin at the sides ; antennae, palpi, and legs pale ferruginous ; body beneath pitchy, with a few scattered hairs. Length 1\ line. 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 2 116 Mr. F. P. Pascoe on some new or little-Jcnown 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. Glyptolopus [Colydiidae]. Erichson, Natur. der Ins. Deutschl. iii. p. 292. Glyptolopus histeroides. (PI. VIII. fig. 5.) G, late ovatus, piceus ; prothorace elytrisque rugoso-costatis. Hab. Brazil (Rio). Broadly ovate, pitchy-black; head coarsely punctured, small, ver- tical, scarcely visible above, narrowed below the eyes ; antennae twelve- jointed, the first large, incrassated, and uncovered at its insertion, the second short, not thicker than the third, the remainder becoming gradually stouter to the tenth and eleventh, the last small, closely enveloped in long silky hairs; prothorax semicircular^ very convex, vaulted above and emarginate anteriorly, the centre with a broad longi- tudinal groove, and a stout interrupted costa on each side, the lateral margin strongly produced, the intervals coarsely punctured ; scutellum triangular ; elytra as broad as the prothorax at the base, but not con- tinuous with it above, the sides rounded and gradually decreasing pos- teriorly, with five strong rugose costse on each, the intervals coarsely punctato-granulate ; all the coxse distant, tibiae fusiform, strongly fluted, not spm'red, tarsi short ; prostemum very strongly keeled, pro- duced behind, and received in a notch of the mesosternum ; first abdo- minal segment nearly as large as the rest together; body beneath coarsely punctured. Length 2 lines. 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.

Maxillary palpi with the second and third joints thickest, the terminal obconie, truncate ; the labial short, triangular, approximate. Maxillary lobes narrow, nearly equal. Prothorax transverse, narrower and slightly emarginate in front, rounded at the side, the base bisinu- ated. Elytra slightly convex, margined, the base closely applied to the prothorax, but enlarging behind the shoulder, then rounded to. the apex.

Length 11 lines. DioPTOMA [Lampyridse]. Head exposed. Eyes very large, horizontally constricted, the upper portion smallest, the lower much larger, and completely contiguous. Antennae short, claviform, subapproximate, deeply set on each side of the narrow prolongation of the front, twelve-jointed, the first two in- crassated, the remainder forming an elongated club. 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.

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. This genus is not very fiir removed from the last ; and, judging 120 Mr. F. P. Pascoe on some new or IHtle-Tcnoivn both from the figure and the description, I think that it is also allied to Erichson's Latometm^. 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. * Wiegmann's Arcliir, 1842, p. 213. pi. 5. fig. 3.

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. Sphargeris pTiysodes. (PI. V. fig. 9.) ^S". testaceus, subnitidus, pimctulatus ; oculis mandibulisque nigTis. Hah.

Length 3 lines. Ch-styllus [Tenebrionidae]. Head subtriangular, rounded posteriorly, larger than the prothorax, its supra-antennary borders forming a short, thick, elevated protuberance. Antennae moderately long, eleven-jointed, the first incrassated, the Genera and Species of Coleoptera. 123 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.

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 124 Mr. F. P. Pascoe on some new or Uttle-hioiun 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. Dipsaconia pyritosa. D. elongato-ovata, hirta, rufo-fusca; prothorace elytrisque nigro-varie- gatis. Hah. Australia (Melbourne). Elongate-ovate, reddish-brown, closely covered -vvith short, thick, strongly hooked hairs ; prothorax narrower than the elytra at the base, the disc with a large irregular blackish patch \ scutellum indistinct, subquadrate ; elytra rather broader behind, striato-punctate, marked with several in-egiilar, dull brownish-black patches ; antennae brown ; body beneath and legs ferruginous-brown, sparingly pubescent.
