 XVIII. On the Genera of the Cossonidaa. 
 By T. VERNON WOLLASTON, M.A., F.L.S. 
 
 [Read 2nd June, 1873.] 
 
 HAVING determined during the past winter to examine 
 critically the structural characters of the various genera 
 of the Cossonidcs (so far as accessible) which have hitherto 
 been published, I soon perceived that a very small pro- 
 portion of the numerous species which were submitted to 
 me could by any possibility be embraced by the 29 groups 
 which were acknowledged by Lacordaire, and which have 
 been admitted subsequently (with two or three additions) 
 into the Munich catalogue. And moreover the excessive 
 inaccuracy of the greater number of the diagnoses, as 
 given by Lacordaire ( for which however he was not 
 himself responsible, they having simply been epitomized, 
 at times perhaps somewhat in haste, from the different 
 authors by whom they were originally compiled), made it 
 but too evident that, in order to define them aright, no 
 asserted peculiarity could be trusted as necessarily true, 
 but that every single feature would have to be collated 
 afresh, and on an independent basis. This being the case, 
 it will at once be seen that my object in the present memoir 
 has not been to monograph the species ; and therefore in 
 two or three extensive and well-established genera, such as 
 Cossonus and Rhyncolus, I have been content to select a 
 few types, from distant parts of the world, and to treat 
 them as representing their respective groups. Yet this 
 very method of proceeding has involved the necessity of 
 examining at any rate certain species with the utmost 
 care ; and as an accurate list of these will be found at the 
 close of my paper, it follows that the members of the 
 family which are there catalogued (amounting to 253) 
 may be looked upon as arranged systematically in accord- 
 ance with my own views. 
 
 At the same time I would not intend to imply that no 
 other representatives of the groups which are more par-

428 Mr. T. Vernon Wollaston on the 
 
 ticularly extensive have been carefully overhauled, for 
 amongst the Cossoni, for instance, a very large number 
 have passed under my eye ; but since I am not desirous 
 of undertaking to determine critically their exact specific 
 titles (which would be rather the work of a separate 
 monograph), I have thought it safer to leave them un- 
 noticed in my general list, lest a possible misquotation of 
 the names might result in confusion as regards the nomen- 
 clature. 
 
 To those Coleopterists who have granted me the loan of 
 their specimens, in this somewhat difficult task, I would 
 desire to return my warmest thanks. To Mr. Pascoe 
 and Mr. Fry my acknowledgments are especially due, 
 both of whom have, with characteristic liberality, placed 
 their large and valuable Cossonideous collections at my 
 entire disposal. It is indeed to the former that I am in- 
 debted for many of the most remarkable types which I 
 have been thus enabled to examine, his series including, 
 in addition to some curious modifications from Australia, 
 a large proportion of the species which were obtained by 
 Mr. Wallace in the islands of the Malayan Archipelago ; 
 whilst the rich material of Mr. Fry in the number of its 
 South- American forms stands probably unrivalled. To 
 Mr. Janson also I must express my peculiar obligations, 
 the whole of his examples having been generously entrusted 
 to me without reserve ; and my worthy friend John Gray, 
 Esq., and Dr. Sharp have likewise afforded much valuable 
 aid in communicating all the members of the family that 
 they respectively possess. The former in fact owns the 
 most complete set of European Cossonids with which I am 
 acquainted; whilst the latter has contributed, amongst 
 numerous other genera (many of which had been trans- 
 mitted, lately, by Mr. Lawson, from New Zealand), the 
 very rare and minute Alaocyba carinulata of Mediter- 
 ranean latitudes. M. Roelofs, also, of Brussels, has had 
 the kindness to send for inspection his unique type of the 
 Georrliynclius Mortctii, from Monte Video ; and I need 
 not here allude again to the interesting material, amassed 
 in Japan, of which Mr. G. Lewis has granted me the 
 loan, it having formed the subject for a separate enume- 
 ration in a late Number of the Entomological Society's 
 Transactions. 
 
 As regards the method of arrangement, it has been my 
 endeavour to arrive, so far as is possible, at a natural one. 
 Had I been content to adopt a purely artificial plan, the 
 
Genera of the Cossonides. 429 
 
 various generic characters might have been more easily, 
 and completely) tabulated ; but since in that case a con- 
 siderable number of groups which I am satisfied have no 
 real affinity with each other would have been brought into 
 juxta-position, I have preferred to sacrifice even convenience 
 in identification to the more important principle of a cor- 
 rect adjustment of the several types.* On this account 
 it is, that while acknowledging the exact number of the 
 funiculus-joints as of primary signification, I have not 
 allowed it to over-ride (in a few exceptional instances) a 
 combination of other features which more than counter- 
 balance it in structural importance ; and hence amongst 
 the true Cossonides, in which that organ is essentially 
 7 -articulate. I have admitted one genus ( Tetracoptus) in 
 which the funiculus is composed of four joints, two 
 (Pentamimus and Tomolips) in which it is made-up of 
 five, and one (Hex or thrum) in which it consists of six, 
 for it would be simply preposterous to include the first of 
 these amongst the Dryophthorides (with which in other 
 respects it has absolutely nothing in common), and the 
 second and third amongst the Pentarthrides , or to asso- 
 ciate the fourth (which belongs to the sub-Hylastideous, 
 asperated types) with the anomalous and more or less 
 fossorial Onycholipides in which the body is pallid and 
 somewhat hairy, the tibial hook obsolete, and the tarsi 
 strictly tetramerous. Moreover Lacordaire has himself 
 acknowledged this principle by placing Hexarthrum in 
 the same situation as I have done, namely towards the 
 close of the subfamily Cossonides ; and it is a method 
 indeed which is acted upon, more or less, in nearly every 
 department of the Coleoptera. 
 
 With respect to the singular cluster of forms which I have 
 brought together under the Onycholipides, they might 
 well be supposed, if viewed per se, to pertain to some totally 
 distinct (and perhaps as yet undefined) family of the 
 Rliynchophora ; but they are nevertheless so unmistake- 
 ably connected on the one hand, by means of Halorhyn- 
 chus and Pentatemnus, with the Pentarthrides, and on the 
 
 * Finding it next to impossible in the subfamily Cossonides to tabulate 
 the characters of more than a small number of the very numerous genera 
 (whilst, at the same time, adhering to what I believe to be the natural 
 sequence of the latter), I have, instead, and as a slight assistance towards 
 the identification, noted a few diagnostic features of each successive group; 
 and, as a still further aid to the eye, I have cited the particular country to 
 which the several genera are peculiar, or in which they more especially 
 predominate. 
 
 I I 2 
 
430 Mr. T. Vernon Wollaston on the 
 
 other^ through Alaocyba, Lipommata, and Stypliloderes, 
 with, the Cossonides proper, that it is well-nigh impossible 
 to doubt (despite their subfossorial habits, 6-jointed funi- 
 culus, quadriarticulate feet, obsolete tibial hook, and other 
 eccentricities) that the present family is their natural 
 location. 
 
 Although dissenting from the views of Lacordaire, in 
 recognizing no particular department which is characterized 
 par excellence, like his Lymantides, by the shortness of 
 the metasternum (for there is scarcely a single item of the 
 structure which varies more, according to the exact genus, 
 and sometimes even according to the species, than the 
 latter), I have nevertheless not departed greatly from the 
 method of arrangement which was adopted by him ; and if 
 there could have been any doubt that the Dry ophtlior ides 
 constitute an integral portion of the family, it would be 
 completely dispelled by the existence of such links as 
 Chcerorrhinus and Pentacoptus (the former of which, in- 
 deed, although, like the latter, manifestly Pentarthrideous, 
 has actually been cited hitherto, through an unpardonable 
 error in its original diagnosis, as a Dryophthorid) and still 
 more by that wonderful genus Synommatus, from Borneo, 
 the distinctive peculiarities of which are so evenly 
 balanced between those of the Dryophthorides and Pentar- 
 thrides that it is by no means easy to decide into which of 
 the two subfamilies it should be received. 
 
 There are six genera, however, of those hitherto pub- 
 lished, which I have not been able to procure for exami- 
 nation ; and these therefore (having convinced myself by 
 experience that recorded characters are seldom completely 
 to be trusted) I am compelled to leave in doubt, merely 
 placing their names between brackets (not altogether un- 
 accompanied by a few remarks, gleaned from their re- 
 spective diagnoses) in order to indicate the several positions 
 which it seems to me not unlikely that they will be found 
 to occup3 r . The genera to which I allude are as follows : 
 Lymantes (from North America), Aparoprion (from the 
 south of Europe), Oodemas (from Tahiti), Mimus (from 
 Southern Africa), Porthetes (likewise South- African), and 
 Proeces (from Madagascar). 
 
 Of the twenty-nine groups acknowledged by Lacordaire, 
 I have rejected Phcenomerus, being satisfied that it is 
 not truly a member of the CossonidcB. Its general facies 
 and considerably developed prosternum bespeak, I cannot 
 but think, a much nearer relationship with the Sphadas- 
 
Genera of the Cossonidcc. 431 
 
 mides and Mecopus ; and although the breast is not chan- 
 nelled for the reception of the rostrum, some of the species 
 nevertheless have a faint tendency for the slight pectoral 
 cavity which is very appreciable in Spho.dasmus, Mecopus, 
 &c., and which implies at all events an exceedingly different 
 situation, in a natural system, to that which is occupied 
 by the Cossonids. Moreover, the large and robust spine 
 with which its intermediate tibias are furnished towards 
 their external apex is quite without precedent in the present 
 family, and I have had no hesitation therefore in expunging 
 the genus from our list. 
 
 Glancing at the 122 genera embodied in this paper 
 (75 of which have been treated as new), there are one 
 or two points to which it may be worth while to draw 
 attention. Thus, the only groups, outside the anomalous 
 subfamilies Notiomimetides and Onycholipides, in which 
 the tibial hook (that almost universal appendage) is 
 obsolete, are Thaumastophasis , Aorus, Lipancylus, and 
 Xenocnema (though in Homaloxenus it is greatly reduced 
 in dimensions). And we might perhaps add Amorpho- 
 cerus to the number, were it not that the tibiae in that 
 genus are eminently spinose at their apex ; and it may be 
 a question how far the largest of the terminal spines, 
 although not proceeding from the outer angle, represents 
 the tibial uncus. Another feature which might be noted, 
 and which certainly is not in accordance with what I had 
 originally imagined, is the excessive rarity of anything 
 approaching to a dentate structure of the femora. The 
 only group indeed, the truly Cossonideous affinities of 
 which are beyond a question, in which it is, so far as I am 
 aware, indicated, is Odontomesites ; and even there the 
 tooth is but obtuse and anguliform, and exists only in the 
 male sex. It is however more strongly expressed in Notio~ 
 mimetes, Coptorhamphus and Homaloxenus, -all of which, 
 nevertheless, are, in other respects likewise, abnormal, 
 their right of location in the present family being possibly 
 open to dispute. The third peculiarity, concerning which 
 I would say a few words, is more superficial, and yet, as a 
 mere aid in the identification, it is practically of consider- 
 able importance : I refer to the extreme scarcity of metallic 
 tints which is observable amongst the Cossonids. A 
 brassy lustre, sometimes merging into green, is almost the 
 only one of which I am cognizant, and even that is re- 
 markably uncommon. It is conspicuous however (albeit 
 subject to complete obliteration) in Lamprochrus and 
 
432 Mr. T. Vernon Wollaston on the 
 
 Acanthomerus, from St. Helena, in some of the Madeiran 
 Caulotrupides, and in Oodemas, from the Sandwich 
 Islands, a genus which I have not been able to procure 
 for inspection. We see it also, though much less power- 
 fully indicated, in the Sericotrogus subcenescens from New 
 Zealand, and in certain of the Phlceophagi, as, for in- 
 stance, the European P. ceneopiceus; and it is about 
 equally traceable in the Pseudophlceophagus tenax, of the 
 Madeiran and Azorean archipelagos. Except in these 
 particular instances I have no evidence of its existence ; for 
 in the Pachy stylus dimidiatus, from Chili, as well as in 
 two Pentarthra from the same region, it is so excessively 
 faint as to be hardly even recognizable. But what I should 
 regard as far more significant, in a systematic point of 
 view, is the occasional obsoleteness., or even total absence, 
 of the scutellum, for in by far the greater number of the 
 Cossonids that organ is (in proportion to their size) largely 
 expressed. In the small subfamilies however of Notiomi- 
 metides and Dry optlior ides, as well as in 13 genera of the 
 Pentarthrides , 2 of the Onycholipides, and 10 of the true 
 Cossonides (making 30 groups in all, out of the 122), it 
 is either altogether untraceable, or else so far reduced in 
 dimensions as to be detected with difficulty ; and it will be 
 seen by a reference to my tabular synopsis that I have made 
 use of this fact in locating the particular types to which it 
 applies. 
 
 The curious instability which is indicated amongst the 
 representatives of the present family, in the exact number 
 of the funiculus joints, is more than paralleled by the 
 occasional obliteration (whether wholly or in part) of the 
 organs of sight. The only member however of the true 
 Cossonides in which the eyes, so far as I am aware, are 
 absent, is the Lipommata calcaratum, a pilose, Phlceo- 
 phagus-l^Q Cossonid, of slightly burrowing propensities, 
 which lives about the roots of sand-plants in the island of 
 Porto Santo, of the Madeiran archipelago. But in the 
 anomalous subfamily Onycholipides, no less than three 
 genera (out of the four) namely Onycholips, Raymondio- 
 nymus, and Alaocyba are totally blind ; and the Aus- 
 tralian Halorhynchus, which (although pertaining to the 
 latter) is exactly osculant between the Onycholipides and 
 Pentarthrides, is in a similar condition. And there are 
 four other Pentarthrideous types namely Pentatemnus, 
 Pseudow.esoxenus, Amaurorrhinus, and Heteropsis, as 
 well as the single exponent of the abnormal subfamily 
 
Genera of the Cossonidce. 433 
 
 Notiomimetides, in which the visual organs are so far 
 reduced in dimensions, and so rudimentary in character, as 
 to be emphatically obsolete, 
 
 Into the question of the geographical distribution I need 
 not now enter, for a glance at the systematic catalogue 
 will suffice to shew approximately what the ranges are of 
 the several types. It is curious however to note how large 
 a proportion of the latter, which have hitherto been brought 
 to light, possess insular habitats ; and, if we except the 
 great and almost cosmopolitan genus Cos s onus, it would 
 seem as if islands afforded conditions more peculiarly 
 favourable for the modes of life of the members of the 
 present family. And this completely accords with my 
 own experience in the sub- African archipelagos, no island 
 appearing to be too minute for the modus vivendi of the 
 Cossonids. In the Maderian and Canarian groups there 
 is scarcely any fact more distinctly observable, where 
 every detached rock is tenanted by some one represen- 
 tative, or more, of this particular department. Nor are 
 trees and shrubs (which seldom flourish in localities thus 
 weather-beaten and exposed) by any means essential for 
 their support, the pithy stems of the ordinary plants 
 being amply sufficient to sustain them ; and I have 
 frequently found the stalks of dead Thistles and Umbel- 
 lifers to be perforated through-and-through by their 
 ravages. In our own country the Cossonids would seem 
 to play a very insignificant part amongst the Coleopterous 
 population, only nine members having hitherto been re- 
 corded ; whereas at the Canaries (made up, as they are, 
 of so many islands and islets) I have myself met with no 
 less than fourteen, and at the Madeiras (which present a 
 considerably smaller area) with nineteen ; whilst even in 
 the little island of St. Helena (the geographical base of 
 which does not exceed that of the Isle of Wight) as many 
 as fourteen have already been noted, and these I have good 
 reason to suspect represent but an instalment of its whole 
 Cossonideous fauna. The British members of our present 
 family are as follows : Pentarthrum Iluttoni, Woll. 
 (= Rhyncolus Hervei, Allard) ; Phlceophagus spadix, 
 Hbst., and aneopiceus, Bohm. ; Rhopalomesites Tardii, 
 Curt.; Cossonus ferrugineus, Clairv. ; Rhyncolus ater, 
 Linn. (= chloropus, Fab.), cylindrirostris, Oliv. (= lig- 
 narius, Mshm.), and gracilis, Rosenh. ; and Stereocorynes 
 truncorum, Germ.

 I will merely add that in treating the subject-matter of 
 the present memoir, it has divided itself into five parts: 
 
 (1) A catalogue of the several groups arranged syste- 
 matically, and (so far as I have been able whilst adhering 
 to what I believe to be their natural sequence) tabulated ; 
 
 (2) full generic diagnoses, taken seriatim ; 
 
 (3) observations (diagnostic and geographical) on each 
 separate genus ; 
 
 (4) brief characters of 139 species which, so far as I am 
 aware, have not hitherto been recorded ; and 
 
 (5) a complete list of the particular members of the 
 family (amounting, in all, to 253), the structural and 
 specific features of which I have examined with the greatest 
 care, and which may be regarded consequently as the 
 material from which the paper has been compiled.

 1. NOTIOMIMETES (nov. gen.). If the minute insect 
 (scarcely one line in length) from which the details for the 
 present genus have been compiled, and which I have re- 
 ceived from Mr. Pascoe as having been captured on the 
 sea-shore at King George's Sound in the south of Aus- 
 tralia, be (as I think, from the structure of its abdomen, 
 antennas, and general facies, that it is) a veritable member 
 of the Cossonidce, it appears to me to be absolutely neces- 
 sary to erect a separate subfamily to receive it ; for 
 although in its most significant character of a 4-jointed 
 funiculus, as well as in its fusiform outline and obsolete 
 scutellum, it agrees sufficiently with the Dry ophthor ides, 
 it is nevertheless so radically different from the exponents 
 of that section in the fact of its tibise being free from a 
 terminal hook, in its very widely separated coxag (which 
 are more remote from each other than in any Cossonid 
 which I have yet seen), and in its pseudotetramerous feet, 
 that I do not believe it can possibly be associated with 
 them. Indeed its apically-unarmed tibiae would, in my 
 opinion, have almost sufficed to exclude it from the Cosso- 
 nidce altogether, was not that particular feature one of the 
 main characteristics of the subfamily Onycholipides, which 
 I have regarded (and, I cannot but think, correctly so) 
 as aberrant, fossorial Cossonids. Moreover its immersed 
 head and obsolete eyes, as well as its bald and rather 
 shining surface (which is entirely free from mud-like 
 scales), are characters which are quite unprecedented in 
 any of the hitherto-known representatives of the Dryopli- 
 thorides. 
 
 In other respects (each of them of considerable im- 
 portance), Notiomimetes recedes from the Dry ophthor ides 
 
Genera of the Cossonidce. 505 
 
 in its exceedingly minute size ; in its surface, although, 
 deeply sculptured, being very much less so than in that 
 subfamily ; in its slenderer rostrum, which has the antennas 
 implanted a trifle before (instead of behind) the middle ; 
 in its elytra being more attenuated posteriority, and with- 
 out any trace either of costas or of the cariniform structure 
 on either side of their apex ; in its antennas (which are 
 much less incrassated) having their scape suddenly thick- 
 ened into a very elongate apical knob, their funiculus- 
 joints (the second one of which is appreciably longer than 
 those which follow it) more loosely connected inter se, and 
 their club larger and more abrupt ; in its femora being 
 armed beneath with, a very small and indistinct tooth ; 
 and in its feet (which, as just stated, are pseudotetramerous) 
 being broader and more abbreviated, the first and second 
 articulations (particularly the latter) being transverse, the 
 third one deeply bilobed (but with the lobes not divari- 
 cating), and the ultimate one (the claws of which are very 
 largely developed) short and thick. 
 
 2. PSILODRYOPHTHORUS (nov. (/en.). In its 4-jointed 
 funiculus, transverse eyes, obsolete scutellum, costate elytra, 
 and slender, pentamerous feet, the remarkable insect for 
 which the present genus is established, and which has 
 been communicated by Mr. Pascoe as having been taken 
 by Mr. Wallace at Saylee, in the north-west of New 
 Guinea, is essentially a Dryophthorid ; and yet it is an 
 exceedingly anomalous member of its subfamily, more 
 especially in the fact of its surface (instead of being opake 
 and thickly besmeared with dirty, mud-like scales) being 
 slightly shining, and almost bald, the punctures only (or 
 a certain portion of them) being filled-up with the parti- 
 cular kind of brown deposit which is so characteristic of 
 the immediately-allied forms. And it is further conspi- 
 cuous for its prothorax (which is largely developed) being 
 almost as wide behind as the base of the elytra, and nearly 
 even., there being scarcely any indication of inequalities, 
 or of an anterior constriction ; and for its elytra being 
 broadly and distinctly scooped-out in front (causing the 
 shoulders to appear prominent, or porrect), and without 
 any tendency to be cariniform at their apex. Its rostrum 
 is rather short, thick, and cylindrical (being of nearly 
 equal breadth throughout), and is not roughened as in the 
 generality of the Dryophthorides.

 3. STENOMMATUS (nov. gen.). The very interesting 
 little insect on which I have founded the present genus is 
 from Mexico, and has been communicated by Mr. Fry. 
 While possessing all the essential features of the Dryoph- 
 thorides (as instanced by its 4-jointed funiculus, elliptical 
 body, transverse eyes, obsolete scutellum, conspicuously 
 5-articulated feet, and minute claws), it recedes completely 
 from Dryophthorus proper (and, therefore, a fortiori, from 
 Tetratemnus) in several most important particulars,^ 
 especially however in its considerably longer, slenderer, 
 more parallel and arcuated rostrum ; in its very much nar- 
 rower and more transverse eyes (which are so narrowed, 
 and prolonged, beneath the head, as to be nearly con- 
 fluent) ; and in all its coxas, though particularly the four 
 posterior ones, being more widely separated. In other 
 respects it differs from Dryophthorus in its smaller size 
 and still more elliptic outline, which is a good deal at- 
 tenuated at its hinder apex; in its surface (instead of 
 being unequally besmeared with a kind of coarse, mud- 
 like, scaly deposit) being densely and evenly covered with 
 an extremely fine, velvety, somewhat silken, cinereous 
 pubescence ; in its elytra not being cariniform at their 
 extremity, though with their second costa (or raised costi- 
 form interstice) more conspicuously elevated, or prominent, 
 behind ; in its antennas (particularly as regards the scape) 
 being longer, and with the club more developed ; and in 
 its metasternum being a little shorter. 
 
 4. DRYOPHTHORUS (Schonherr, Cure. Disp. Meth. 
 332. 1826). Although I have had no opportunity of 
 examining them, I believe that the majority of the species 
 which have been referred to Dryophthorus are generically 
 distinct from the European D. lymexylon, which is ex- 
 pressly stated to be the type of the group ; and I suspect 
 therefore that the genus Tetratemnus , which I lately enun- 
 ciated in order to receive an insect which was taken abun- 
 dantly by Mr. G. Lewis in Japan, will be found eventually 
 to embrace them. Be this however as it may, the genus 
 Dryophthorus, as represented by its acknowledged type, 
 is too well known to require comment ; suffice it to observe 
 that the various published diagnoses of it (not even ex- 
 cepting that of Lacordaire) appear to me to be at fault in 
 their definition of some of its most important characters, 
 the result apparently of their having been drawn out, not 
 from the type alone, but partially also from some of the 
 
Genera of the CossonidcE. 507 
 
 allied forms which I regard as Tetratemni. In Dryoph- 
 thorus proper, however, the anterior coxas are rather more 
 approximated than in Tetratemnus, the body is more 
 elliptic (or medially-widened), the prothorax is a trifle less 
 developed, the elytra are not so broadly cariniform at their 
 apex, and the rostrum, antennas, and legs are appreciably 
 longer. Nevertheless in their opake and very coarsely- 
 sculptured surface (which is more or less densely besmeared 
 with whitish-brown, mud-like scales), as well as in their 
 costate elytra and 4-jointed funiculus, and in the fact of the 
 fourth articulation of their slender, filiform feet being (in- 
 stead of minute and hidden) exposed and distinct, the two 
 genera are coincident. The D. lymexylon, which (as just 
 stated) may perhaps prove to be the only Dryophthorus 
 proper hitherto made known, appears to occur, more or 
 less sparingly, throughout northern and central Europe. 
 
 5. TETRATEMNUS ( Wollaston, Trans. Ent. Soc.Lond. 9. 
 1873). As already implied, the members of this genus, 
 which (if my conclusions be correct) are eotfra-European 
 and appear to be widely spread over the world, present 
 many characters which, as it seems to me, cannot but 
 distinguish them generically from the European Dryoph- 
 thorus lymexylon. Not to speak however of those species 
 which I have had no opportunity of examining, and which 
 may or may not prove to be Tetratemni, I may add that 
 at any rate the Japanese Cossonid (the T. sculpturatus, 
 Woll.) for which the group was proposed, recedes from the 
 D. lymexylon in its anterior coxas being rather more 
 widely separated, whilst the hinder pair, on the contrary, 
 are not quite so remote as in that insect ; in its antennas, 
 rostrum, and legs being a little shorter ; in its prothorax 
 being proportionately a trifle more developed ; in its elytra 
 being narrower and more parallel (or laterally-compressed) 
 and very much more broadly cariniform on either side of 
 their apex ; and in its tarsi being especially more abbre- 
 viated. Its rostrum also is less appreciably widened 
 immediately in front of the particular point at which the 
 antennas are inserted. Its dark and opake surface how- 
 ever is as coarsely sculptured, and besmeared with the 
 same kind of whitish-brown, mud-like scales (or, as it 
 were, scaly deposit), as in Dryophthorus proper. Although 
 it is probable that the group has a wide geographical 
 range, the T. sculpturatus is, (for the reason already

508 Mr. T. Yernon Wollaston on the 
 
 given, the only member of it for which I am at present in 
 a position to vouch ; and that one appears to be common 
 in the Japanese archipelago, having been met with by 
 Mr. G. Lewis near Nagasaki in the island of Kushiu, and 
 at Hiogo in the island of Nipon. 
 
 6. SYNOMMATUS (nov. gen.}. If there had been any 
 question concerning the intimate relationship which exists 
 between the Dry ophthor ides and Pentarihrides (of which 
 I have never myself entertained the slightest doubt), it 
 would have been thoroughly dispelled by a genus like the 
 present one, which, although pertaining to the latter, is 
 at first sight so unmistakeably a Dryophthorid that it is 
 difficult to conceive that it can belong to any other group. 
 Yet the most essential features of that well-marked sub- 
 family, namely a 4-jointed funiculus and ordinary penta- 
 merous feet, are entirely wanting to it, the former in 
 Synommatus being ^/zz^-articulate, and the latter on the 
 usual Rhynchophorous pattern. Yet so marvellously do 
 its external facies, sculpture, and clothing, no less than its 
 narrow, transverse, sunken eyes, the general proportions 
 of its rostrum and antennae (barring the extra funiculus- 
 joint), and the structure of its abdomen and tibiae accord 
 with Dryophthorus that one can scarcely resist the con- 
 viction that it is as much a member of the one subfamily 
 as of the other ; and my own opinion, consequently, is that 
 it is as nearly as possible osculant between the two. 
 Although agreeing very much better than Pentacoptus 
 and Chcerorrhinus do with the Dry ophthor ides > yet in con- 
 junction with those genera (in the latter of which the elytra 
 are cariniform on either side of the apex) it may be said 
 to constitute a most complete passage between the sub- 
 families in question, though of necessity claimed by the 
 Pentarihrides (with which, however, it has far less, primd 
 facie, in common) on account of the structure of its funi- 
 culus and feet. 
 
 In the formation of its eyes Synommatus stands alone 
 amongst all the Cossonideous types with which I am 
 acquainted, the nearest approach to it being the genus 
 Stenommatus from Mexico; for not only are they very 
 much more approximated on the upper-side than is the 
 ease in any of the Dryophthorids which have hitherto 
 been brought to light, but (which is still more anomalous) 
 they are completely confluent beneath, the two to- 
 gether, consequently, well-nigh encircling the entire head ! 
 
Genera of the Cossonidce. 509 
 
 Amongst other peculiarities, our present insect is remark- 
 able for its elliptic outline, for its long and parallel but 
 arcuated rostrum, for its funiculus being- gradually much 
 increased in width towards the club, and for the latter 
 being extremely large and solid, though obliquely trun- 
 cate at the inner apex, at which particular point it is 
 densely clothed with a velvety pubescence. Its prothorax 
 (which is but slightly constricted in front) is nearly cylin- 
 drical, and very much -narrower than the elytra, the latter 
 (which have their interstices, especially the alternate ones, 
 costiform) are wide in front but acuminated behind, its 
 legs are exceedingly long and thickened, its tibiae are 
 somewhat curved (the four hinder ones moreover being 
 armed at their apical angle with a short but robust spine), 
 its third tarsal joint is simple, and its front coxas are con- 
 tiguous, the intermediate ones but very slightly separated, 
 and the hinder pair exceedingly remote. 
 
 The S. confluens is from the collection of Mr. Pascoe, 
 and was taken by Mr. Wallace at Sarawak in Borneo. 
 
 7. CmERORRHiNUS (Fairmaire, Ann. de la Soc. Ent. 
 de France, 742. 1857). I am indebted to John Gray, 
 Esq., for an opportunity of inspecting the European genus 
 Cheer orrhinus, of Fairmaire ; and it is not without the 
 greatest astonishment that I have observed the excessive 
 inaccuracy of the original diagnosis in assigning it to the 
 Dry 'ophthor 'ides, an inaccuracy which is quite unpardon- 
 able, and which has misled every subsequent author (in- 
 cluding even Lacordaire) who has been content to trust to 
 the published details, and not to examine them for him- 
 self. The primd facie aspect of its opake, deeply-sculp- 
 tured surface, which is besmeared with dirty, mud-like 
 scales, in conjunction with the cariniform structure on. 
 either side of its elytral apex, are without doubt marvel- 
 lously suggestive of Dryophthorus, so much so indeed 
 that it may fairly be regarded as establishing, in conjunc- 
 tion with Synommatus, a curious affinity between the 
 Dryophthorus-type and the subfamily Pentarthrides (to 
 which it belongs) ; but there the resemblance altogether 
 ceases ; and it is surprising how any careful Coleopterist 
 could be misled by characters so eminently superficial. 
 In real fact its funiculus is fiv ^-articulate, which at once 
 removes it from the Dryophthorides in which that organ 
 is composed of only four joints. Then its feet are on the 
 ordinary pseudotetramerous pattern, instead of as in the 
 
 o o 2 
 
510 Mr. T. Vernon Wollaston on the 
 
 Dryophthorides distinctly 5-jointed (the fourth one in that 
 subfamily not being minute and hidden, but appreciable 
 arid unreceived).- Yet so completely was Lacordaire led 
 into error by the original diagnosis, that he not only 
 accepted the insect (on account of the supposed structure 
 of its fttniculus) as a Dryophthorid, but naturally enough 
 felt compelled so far to modify the characters of that well- 
 defined subfamily so as to admit within its bounds the 
 ordinary pseudotetramerous foot ! It is, however, in re- 
 ality, a normal member of the Pentarthrides, and is very 
 intimately related to my genus Pentacoptus which was 
 detected by Mr. Gr. Lewis in Japan. It completely lacks, 
 moreover, the fusiform, or subelliptic, outline of the Dry- 
 ophthorides ; whilst its exceedingly incrassated legs and 
 tarsi are in strange contrast with those of that subfamily 
 in which those parts are comparatively thin and wiry ; 
 and its eyes (instead of being sunken, transverse, and de- 
 pressed) are rounded and very prominent as in the Pen- 
 tarthrideous Pentacoptus. Its metasternum too is shorter 
 than that of the Dryophthorid.es; and its four anterior 
 coxaa are perceptibly more approximated. 
 
 From the Japanese Pentacoptus (to which it is inti- 
 mately allied), Ch&rorrhinus differs mainly in its larger 
 size and less narrowed prothorax, in the cariniform struc- 
 ture on either side of its elytral apex, in its anterior coxa3 
 being rather less widely separated, and in its first and 
 second abdominal segments being divided by a very deeply 
 sinuated line, instead of a perfectly straight one. 
 
 The Chcsrorrhini appear to occur in southern Europe, 
 the genus having been first met with in Sicily. 
 
 8. PENTACOPTUS (Wollaston, Trans. Ent. Soc. Lond. 
 12. 1873). In its very coarsely sculptured and opake, 
 though somewhat besmeared surface, its short, broad, 
 parallel rostrum, nearly obsolete scutellum, and costate 
 elytra, the present remarkable little genus has almost as 
 much in common, at first sight, as Charorrhinus has, 
 with the Dryophthorides ; nevertheless its 5-jointed funi- 
 culus, and its small, rounded, and prominent eyes, in con- 
 junction with its elytra showing no traces of the peculiar 
 cariniform structure at their apex which is so marked a 
 feature in that group, its comparatively incrassated legs, 
 and its ordinary pseudotetramerous feet (the third joint of 
 which is a good deal widened and bilobed), will of them- 
 selves at once remove it from the members of that sub- 
 
Genera of the Cossonidce. 511 
 
 family. I have already pointed out in what it principally 
 differs from Cheer or rhinus. It was detected by Mr. Or. 
 Lewis in the Japanese archipelago, namely at Nagasaki, 
 in the island of Kushiu. 
 
 9. LYPRODES (nov. gen.). The single example from 
 which I have compiled the diagnosis of the present genus, 
 which was captured by Mr. Wallace in Sula, one of the 
 islands of the Malay archipelago, has been communicated 
 by Mr. Pascoe ; and it is especially important as supply- 
 ing another well-defined type in the subfamily Pentar- 
 thrides in which the funiculus is only 5-articulate. More- 
 over its opake and deeply sculptured surface, which is 
 densely besmeared with mud-like scales (or, as it were, a 
 kind of dirty-whitish, scaly deposit), added to its almost 
 obsolete scutellum, and its thick, abbreviated feet (the first 
 joint of which is short, and the third one wide and very 
 deeply bilobed), place it in the immediate vicinity of 
 Pentacoptus and Cheer or rhinus. It is abundantly dis- 
 tinct, however, from both of those groups, not merely in 
 its much narrower and cylindric body (which is of nearly 
 equal breadth throughout), but likewise in its much longer 
 and slenderer rostrum, its less incrassated and less abbre- 
 viated antennae (which have their second funiculus-joint 
 appreciably longer than those which follow it), and in its 
 more elongated inetasternum (which indeed is scarcely 
 shorter than that of Pentarthrum and Stenotrupis). Its 
 eyes, although prominent, are less remarkably so than in 
 Pentacoptus ; and its elytral interstices are not so costate. 
 In primd facie aspect the insect calls to mind what we 
 might almost suppose to be an exceedingly diminutive 
 state of the European Lyprus cylindricus, a circumstance 
 which, however fanciful, has suggested both its generic 
 and specific names. 
 
 10. PHLCEOPHAGOMORPHUS (nov. gen.). In its rather 
 lengthened cylindric-ovate outline, which is narrowed in 
 front and gradually expanded behind (the prothorax being 
 considerably reduced in size, and much narrower than the 
 elytra), as well as in the fact of its four anterior coxae 
 being (especially as regards the front pair) greatly approxi- 
 mated, the present genus has much the primd facie aspect 
 of Phlceophagus ; nevertheless its funiculus is only 5-articu- 
 latc, its scutellum is conspicuous, and its rostrum and 
 (much thicker and more abbreviated) antennae are very 
 
512 Mr. T. Vcrnon Wollaston on the 
 
 differently constructed. In reality it belongs to that par- 
 ticular section of the Pentarthrides in which the scutellum 
 is developed and the surface bald, and it is remarkable 
 amongst the immediately-allied forms for its somewhat 
 convex, Phlceophagus-likQ body, for its (rather short and 
 broad) rostrum being a good deal contracted, or as it were 
 pinched-in, at the base, for its eyes being (instead of pro- 
 minent) depressed, and for its four anterior legs being (as 
 in the Phlceophagi) much more approximated at their base. 
 Its surface (which is shining) is of a reddish, and slightly 
 pellucid, chestnut hue, with the head, rostrum, and femora 
 a little darker than the rest; its antennas are somewhat 
 thickened, with their second funiculus-joint not at all 
 elongate ; and its feet have their first articulation (as in 
 Phlceophagus} appreciably lengthened, and their third one 
 minutely (and not very distinctly) bilobed. The example 
 from which the generic details have been compiled is 
 South- American (having been received from New Gra- 
 nada), and has been communicated by Mr. Fry. 
 
 11. PSEUDOPENTARTHRUM (nov. gen.}. The rather 
 obscure little Cossonid which forms the type of the present 
 genus, is from Mexico, and has been communicated by 
 Mr. Fry ; and its primd facie aspect is so much that of a 
 minute and cylindrical Phlceophagus, that until I observed 
 that its funiculus is only 5 -jointed I had regarded it as a 
 member of that group. In reality however it is very close, 
 in affinity, to Pentarthrum, from which it nevertheless 
 recedes in its very much smaller size and shortly-cylindri- 
 cal body, in its more abbreviated and relatively broader 
 (though equally parallel) rostrum, in its prothorax and 
 metasternum being very much less elongated, and in its 
 anterior coxas being much more approximate. Indeed 
 the latter are almost exactly the same as in Phlceophagus, 
 the front pair being nearly contiguous ; and its prothorax 
 also, which is oval (instead of elongate and subtriangular), 
 is almost on the Phloeophagus-patteYn. Its under-seg- 
 ments are slightly scooped-out, or concave, after the 
 fashion which obtains in so many of the Pentarthrides ; 
 its surface is completely bald, black, and but very slightly 
 shining ; and the third articulation of its feet is simple. 
 
 In point of fact, however, the present genus is some- 
 what intermediate between Pentarthrum and Phlceopha- 
 gomorphus, agreeing with the latter in its more approxi- 
 mated anterior coxce ; nevertheless it entirely wants the 
 
Genera of the Cossonidas. 513 
 
 very peculiar rostrum of the latter, which is curiously 
 ])inched-in (or suddenly constricted) at its base ; and it is 
 likewise smaller and more cylindrical (the prothorax being 
 proportionately wider, and the elytra more parallel), of a 
 darker hue and duller surface, with its metasternum and 
 limbs more abbreviated, and with the first joint of its feet 
 less elongate, and the third one more decidedly simple. 
 
 12. XENOSOMATIUM (nov. gen.\ The very minute 
 Pentarthrid for which I have established the present 
 genus has been communicated by Mr. Pascoe, and was 
 captured by Mr. Wallace in the Malayan archipelago. 
 Apart from its diminutive size and 5-articulated funiculus, 
 its greatly abbreviated second funiculus-joint, and its 
 abrupt, largely developed club, it is at once remarkable 
 for the structure of its tibiae, -which are rather short, 
 broad, and triangular, and have their terminal hook in the 
 four posterior ones abbreviated, straight, and spiniform, 
 but still shorter (in fact obsolete) in the front pair (where 
 it is replaced by a robust and 0wwardly-curved pubescent 
 spine which arises from the inner angle). This tibia I 
 modification is very peculiar, and one which I do not re- 
 member to have observed in any other Cossonideous group. 
 In minor details Xenosomatium is conspicuous for its 
 (somewhat short, broad, and arcuated) rostrum being a 
 good deal constricted at the base, behind the insertion of 
 the antennas (which arise nearer to the base than is usual 
 in the Pentarthrideous types ) ; for its scape being long 
 and backwardly-curved, as well as greatly clavate (though, 
 at the same time, obliquely lopped-off at the inner apex) ; 
 for its eyes being extremely large and prominent ; and for 
 its feet having their first three joints thickened and sub- 
 equal, but the ultimate one rather slender. In its piceo- 
 fcrruginoiis hue Xenosomatium agrees with the majority 
 of these immediate forms, but its sculpture is finer and 
 lighter than is usually the case. 
 
 13. PENTARTHRUM (Wollaston, Ann. Nat. Hist. xiv. 
 129. 1854). Judging from the twelve exponents which 
 have hitherto been brought to light, the Pentarthra are 
 more or less narrow and parallel insects, closely sculptured, 
 nearly always free from scales and pubescence, either 
 piceous or castaneous in hue, and but very slightly shining. 
 Their eyes are prominent, and, together with the scutellum, 
 conspicuous ; their prothorax is rather large, and, like the 
 
514 Mr. T. Vernon Wollaston on the 
 
 metasternum, elongate ; their rostrum (which varies in 
 length according to the species, but which is never very 
 long) is robust and linear, though sometimes obsoletely 
 constricted towards the base ; and their third tarsal joint 
 is either slightly bilobed, or else narrow and simple. In 
 the European P. Huttoni, which must be regarded as the 
 type of the genus, as well as in the P. Zealandicum, and 
 in the two species from Chili, the second articulation of 
 the 5 -jointed funiculus is appreciably a little longer than 
 those which follow it ; but this is less evidently the case in 
 the other members of the group which have hitherto been 
 observed. The Pentarthra are somewhat peculiar in their 
 habits, attaching themselves to old planks, boards, rafters, 
 casks, &c., on the dry, and often tinder-like, wood of which 
 they appear to subsist (and that too, occasionally, when the 
 latter are even partly buried in the soil) ; a mode of life 
 which is equally indicated in (the nearly blind) Amauror- 
 rhinus, and in Hexarthrum of the true Cossonides. On this 
 account we may expect that their acquired areas of distribu- 
 tion will be found eventually to be wide ; and, in accordance 
 with this conjecture, it is a significant fact that the expo- 
 nents which have hitherto been discovered should occur in 
 countries so remote from each other as western Europe,* 
 
 * Until quite recently I had looked upon the P. Huttoni as peculiar to 
 England, and indeed it has not as yet been recorded for any other country ; 
 but, having, a few weeks ago, received some Cossonidce from Dr. Sharp, I 
 was surprised to find that two typical examples (which were included 
 amongst them), of the "Rliyncolus Hervei" of Allard (Abeille,v. 475. 
 1869), and which appear to have been captured at Rennes, are identical 
 with my Pentarthrum Huttoni, described (fifteen years before) from 
 examples taken near Exeter. In the Munich Catalogue the department of 
 Finisterre is given as the locality for the "Rhyncolus Hervei ;" so that at 
 any rate the extreme western portion of Brittany is the only region, beyond 
 England, in which it has hitherto been observed ; and it is a significant 
 fact, from a geographical point of view, that that particular district is 
 exactly opposite to Devonshire on the southern side of the Channel. Its 
 precise places of capture in this country are, up to the present date, three, 
 namely, the vicinity of Exeter (where it was met with originally, at 
 Alphington, by my nephew, the Rev. H. W. Hutton) ; Teignmouth (where 
 on two or three different occasions I have myself found it), and Plymouth 
 (where it was detected by Mr. Reading). Apart from its many other 
 characters, the fact of its funiculus being composed of only five joints 
 ought certainly to have prevented it from being re- described as a Rliyn- 
 colnsin which that organ has invariably seven articulations ; but the 
 slovenly manner in which continental entomologists are apt to mount their 
 specimens, every limb and joint being hopelessly concealed beneath, will 
 perhaps explain a blunder which is nevertheless utterly unpardonable. It 
 is scarcely less fragrant however than the similar miscalculation of the 
 funiculus- joints in Cheer orrliinus, which has resulted in that genus having 
 been assigned hitherto to a subfamily with which it has next to nothing in

 14. SERICOTROGUS (nov. gen.}. I am indebted to Dr. 
 Sharp for the very curious little Pentarthrid for which the 
 present genus is established ; and he appears to have ob- 
 tained it from Mr. Lawson, of Scarborough, by whom it 
 was received from Auckland in New Zealand. Its dis- 
 tinct scutellum and largely-developed eyes place it very 
 near to Pentarthrum proper; nevertheless in its smaller 
 bulk, and slenderer aud move fusiform outline (the elytra, 
 as in AmaurorrhinuS) being narrowed anteriorly), and in 
 its somewhat brassy surface, which is sparingly clothed 
 with a coarse, silken, decumbent aeneo-cinereous pubescence, 
 as well as in its less elongated metasternum (which is like- 
 wise more on the Amaurorrhinus type), and the widely 
 bilobed third joint of its feet, it altogether recedes from the 
 members of that group. Its rostrum, too, is a trifle longer, 
 thinner, and more curved than in the majority of the Pen- 
 tarthra, and has the antennae implanted into it rather more 
 conspicuously before the middle ; the latter are a little less 
 thickened ; its head is more exserted : its prothorax (which 
 is slightly concave beneath) is convexer, more regularly 
 rounded at the sides (it being neither subtriangular nor 
 subcylindrical), and is nearly free from an anterior con- 
 striction : and its elytra have apparently no tendency to 
 be separately rounded-off, and subrecurved, at their ex- 
 treme apex. 
 
 15. STENOTRUPIS (nov. gen.). The exceedingly narrow, 
 
 common ; or than placing Hexarthrum amongst the Rhyncoli, because 
 the articulations of the same organ were incorrectly counted ! But if col- 
 lectors will not take the trouble to expand their specimens so that the parts 
 may be distinctly seen, how can we wonder at the inevitable results ? Still, 
 one would at least have supposed that before enunciating a new form, the 
 microscope would, as a matter of necessity, have been appealed to. 
 
 * The presence of my P. cylindricum in the island of Ascension appears 
 to have been (as indeed I always anticipated) merely accidental ; for an 
 example is now before me which was captured by Mr. Fry in Brazil, and 
 another which was taken by Mr. Wallace in Gilolo of the Malayan archi- 
 pelago. In all probability therefore it is a species which, like certain 
 others, is liable to follow in the wake of civilization. 
 
 f The little insect from St. Helena which I described two years ago as 
 an aberrant Pentarthrum, under the name of P. subccecum, proves on a 
 closer examination to be na Pentarthrum at all, but more intimately re- 
 lated to Amaurorrhinus (or Mesoxemis}. It is, however, distinct from 
 even the latter, and forms the type of my genus Pseudomesoxenus, 
 enunciated below. 
 
516 Mr. T. Vernon Wollaston on the 
 
 and sometimes minute, insects for which the present genus 
 is proposed appear to have been confounded hitherto with 
 Catolethrus into which they seem to have been admitted 
 as abnormally small members ; and, in accordance with 
 this, a very pallid and diminutive one, from Cuba, has 
 been communicated by Mr. Pascoe with a very old label 
 appended to it, bearing the name "Catolethrus palmeus, 
 Schon." There is no species, however, of supposed Cato- 
 lethrus, so far as I can ascertain, which bears that specific 
 title, either in the ( Genera Curculionidum' or the Munich 
 catalogue ; and I am compelled, therefore, to conclude 
 that it is an unpublished one ; yet the fact itself tends 
 nevertheless to prove that the exponents of the present 
 genus have, as just mentioned, been associated inadver- 
 tently with the Catolethri. But in reality, when closely 
 inspected, they will be seen to belong to even a "different 
 subfamily from the latter, their 5-jointed funiculus as- 
 signing them at once to the Pentarthrides. In addition, 
 however, to this primary distinction, Stenotrupis recedes 
 from Catolethrus in the insects which compose it jbeing 
 smaller and narrower ; in their head being much longer, 
 thicker, more oval and very much more exserted (or ex- 
 posed) ; in their rostrum being slenderer still, a little 
 widened towards the tip, and not appreciably divided from 
 the forehead; in their prothorax being more triangular, 
 and less constricted behind its apex; in their scutellum 
 being less conspicuous ; in their elytra being minutely 
 pubescent at the apex ; in their four hinder legs being 
 shorter ; in all their coxaa being equally separated, or 
 apart ; and in the third joint of their feet being unex- 
 panded and simple. 
 
 In point of fact, however, Stenotrupis is much nearer 
 to Pentarthrum, particularly to such members of it as 
 the P. angustissimum, from Japan; yet its species are 
 still narrower and more depressed ; their head is longer, 
 thicker, oval and exserted ; their rostrum (particularly in 
 the female sex) is more elongated and slender, and appre- 
 ciably widened in front; their eyes (instead of being 
 rounded and prominent) are completely sunken, ovate 
 and 'more approximated above ; their prothorax is more 
 triangular and less constricted behind its apex ; their 
 elytra are minutely pubescent at the tip ; their legs, par- 
 ticularly the four posterior ones, are much shorter ; and 
 their coxas are, all of them, equally separated. 
 
 In all probability Stenotrupis will be found to have a 
 
Genera of the Cossonidce. 517 
 
 wide geographical range, though it is perhaps more 
 strictly tropical than Pentarthrum. At any rate one of 
 the species now before me is from Cuba, and another was 
 captured by Mr. Wallace in Makian one of the islands 
 of the Malay archipelago. 
 
 16. MiCROCOSSONUS (nov. gen.\ The minute Cossonid 
 (which was taken by Mr. Wallace at Saylee on the north- 
 west coast of New Guinea, and which has been communi- 
 cated by Mr. Pascoe) from which the characters for the 
 present genus have been drawn out, is manifestly a good 
 deal allied to Stenotrupis, with which it agrees in its 
 thickened, elongate, greatly exserted head, its narrow and 
 parallel outline, its depressed surface, and in the fact of its 
 legs being equally distant at their base. Nevertheless, if 
 the example before me may be taken as a type of its 
 group, the body is even still smaller than in Stenotrupis 
 (the entire length being scarcely one line), but relatively 
 not quite so slender ; its rostrum (which, as in most of the 
 members of that genus, is appreciably dilated towards the 
 apex) is much shorter and wider ; its eyes are considerably 
 more developed, and not so flattened ; its elytra are free 
 from minute pubescence at their apex ; its antennas are 
 inserted very much nearer to the base of the rostrum ; and 
 its coxa3 (although, as in that group, equally separated) 
 are distinctly more remote. Its general contour and 
 outline are somewhat that of an exceedingly diminutive, 
 flattened, and pallid Me site s ; but its 5-jointed funiculus 
 and the peculiar construction of its, rostrum, as well as its 
 numerous other features, entirely remove it from the sub- 
 family Cossonides. 
 
 17. COSSONIDEUS (nov. gen.). In its comparatively 
 large and Cossonus-V^Q body (which is much depressed, 
 deeply sculptured, parallel-fusiform in outline, and of a 
 rather pale, though somewhat variegated, hue) the curious 
 insect for which this genus is proposed, and which is com- 
 municated by Mr. Pascoe as having been received from 
 Champion Bay in western Australia, seems altogether 
 anomalous amongst the Pentarthrides ; nevertheless its 5- 
 jointed funiculus, and the structure of its robust, parallel 
 rostrum are quite in accordance with the members of that 
 subfamily. Apart, however, from the characters just 
 enumerated, it may be known by its excessively large and 
 
518 Mr. T. Vernon Wollaston on the 
 
 prominent eyes ; by its antennae, which have their second 
 funiculus-joint conspicuously longer than those which 
 follow it, being inserted about the middle of the rostrum ; 
 and by its exceedingly elongate and greatly developed 
 legs, the femora of which are much incrassated, or 
 clavate, and are rather roughened with a few minute 
 and indistinct asperities, or tubercles, on their inner sur- 
 face; whilst the tibiae are sinuated internally, and pro- 
 duced into a small but evident spinule at their inner angle, 
 and the tarsi (especially their terminal articulation) are 
 elongate. 
 
 Cossonideus may very possibly be the representative of 
 an important Pentarthrideous form in Australia ; but in 
 external facies it nevertheless recedes greatly from the 
 Pentarthrides as hitherto known ; though at the same 
 time it must be admitted that the (comparatively diminu- 
 tive) Microcossonus Wallacei, from New Guinea, makes 
 likewise a decided approach (though certainly a less strik- 
 ing one) towards the Cossonus and Mesites type. 
 
 18. TYCHIODES (Wollaston, Trans. EnL Soc. Lond. 
 16. 1873). This is altogether one of the most curious of 
 the Cossonideous forms with which I am acquainted, its 
 rather wide, subdepressed, oblong-elliptic body (which, as 
 in most of the allied groups, is slightly shining, castaneo- 
 piceous, and free from pubescence), in conjunction with 
 its extremely slender and cylindrical rostrum (I believe in 
 both sexes), its short, transverse prothorax, and thickened 
 legs, giving it more the appearance at first sight of some 
 member of the Erirhinides, in the vicinity of Tychius, 
 than of a Cossonid. Its antennae (which are rather 
 slender, and implanted considerably behind the middle of 
 the rostrum) have their scape short and a good deal 
 flexuose (and, as it were, obscurely scooped-ouk on the 
 underside), and likewise the second articulation of their 
 lax, 5-jointed funiculus considerably longer than those 
 which follow it. Its scutellum is very conspicuous, and 
 its feet (which are rather thick, and largely developed) 
 have their third articulation deeply bilobed. Its meta- 
 sternum is a little less elongated than is the case in Pen- 
 tarthrum, Stenotrupis, Lyprodes, Leptomimus, and others. 
 It was detected by Dr. A. Adams in the Japanese archi- 
 pelago, namely on the island of A wasima, off the north- 
 west coast of Nipon. 
 
Genera of the Cossonida. 519 
 
 19. TYCHIOSOMA (nov. gen.}. The insect for which I 
 have founded the present genus is from the Philippine 
 Islands, and has been communicated by Mr. Pascoe. It 
 is very closely allied to the Japanese Tychiodes Adamsii, 
 from which, however, it differs in being not only larger 
 and more depressed and with the limbs longer, but like- 
 wise in having its antennas more medially inserted, with 
 the scape especially more lengthened, less arcuate, and 
 without any tendency to be hollowed-out internally, and 
 with the funiculus gradually much more widened, and 
 consequently with the club (which is itself longer) less 
 abrupt. In addition to which, its prothorax (which is 
 equally small) is more triangular, or less transverse, as 
 well as (together with the under-segments) extremely 
 shining and almost un sculptured ; its prosternum is 
 clothed, between the anterior coxas, with fulvescent pile ; 
 and its front tibia? (instead of being simple) are slightly 
 scooped-out towards their inner apex, the emargination 
 being barbed posteriorly with strong fulvescent hairs. 
 
 20. LEPTOMIMUS (nov. gen.\ The two species now 
 before me for which the present genus is established, and 
 which have been communicated by Mr. Pascoe as having 
 been obtained by Mr. Wallace in the island of Gilolo, of 
 the Malayan archipelago, combine many very curious 
 features which are essentially their own. In their bodies 
 being exceedingly narrow and parallel they agree with 
 Stenotrupis ; but they nevertheless entirely want the 
 elongate, thickened, exserted head, and the completely 
 depressed eyes, of that genus ; their rostrum too is very 
 much more lengthened and slender (not being subdilated 
 anteriorly) ; their prothorax and antennas, as well as their 
 second funiculus-joint, are much more elongated ; the 
 third articulation of their feet is more expanded and 
 bilobed ; and their legs (instead of being equidistant from 
 each other at the base) have the intermediate coxaa rather 
 widely separated, but the front and hinder pairs appreciably 
 (and equally) more approximate. This last-mentioned 
 peculiarity is rather anomalous amongst the Cossonidce, 
 and particularly so amongst the Pentarthrides. In other 
 respects Leptomimus is remarkable for the opake, reddish- 
 brown, and most closely sculptured surface of its two 
 hitherto-discovered exponents, one of which, moreover, 
 is clothed with a short, setiform pubescence, whilst the 
 other appears to be bald. In all probability the group 
 
520 Mr. T. Vernon Wollaston on the 
 
 will be found to play an important part in the Rhyncho- 
 phorous fauna of the Malay archipelago, the L. delicatulus 
 having (as I am informed by Mr. Pascoe) been stated by 
 Mr. Wallace to be common amongst the bamboos. 
 
 21. LAMPROCHRUS (TZOV. gen.). The superb Cossonid* 
 for which the present genus is proposed, and which was 
 discovered by Mr. Melliss at St. Helena, I admitted two 
 years ago (albeit not without some hesitation) to Microxy- 
 lobius, having been content at the time to cite it as a 
 large and aberrant member of that locally-important group ; 
 yet a closer inspection of its real structural details would 
 certainly imply that it must be treated in reality as alto- 
 gether distinct, its extremely elongate and slender rostrum 
 (which in the male sex is rather more robust and sculptured, 
 and slightly dilated before the middle, at the insertion of the 
 antenna3, much after the fashion which obtains in Mesites 
 of the true Cossonides), in conjunction with its equally 
 elongated antennas, legs, and feet (the first of which have 
 their second funiculus-joint, and the last their basal one, 
 greatly lengthened), being of' themselves more than suf- 
 ficient to establish its claims for separation. In its fusi- 
 form outline and shining, brassy surface it might well be 
 mistaken at first sight for a gigantic exponent of that 
 section of Acanthomerus in which the femora are un- 
 armed ; but the characters above enumerated (in addition 
 to its slightly pubescent body, as in certain of the Microxy- 
 lobii proper) will at once distinguish it from the members 
 of that genus. The fact, however, of its funiculus being 
 5-articulate, its scutellum obsolete, and its third tarsal 
 joint deeply bilobed, added to its fusiform outline and its 
 metallic lustre, is too significant not .to indicate its mani- 
 fest relationship with the other Pentarthrideous genera 
 (Microxy lobius proper and Acanthomerus) which are so 
 remarkably developed, as regards their specific modifica- 
 tions, in the little island of St. Helena. 
 
 22. ACANTHOMERUS (Boheman, Res. Eugen. 141. 
 1858). The Acanthomcri, which are peculiar to the 
 island of St. Helena, may be said to be those members 
 of Microxylobius (as hitherto understood) in which the 
 body is highly polished, less sculptured, and brassy, and 
 totally free from any traces of even the minutest pubescence, 
 
 * M. cossonoides, Woll., Ann. Nat. Hist. 403 (1871). 
 
Genera of the Cossonidce. 521 
 
 and in which the second joint of the funiculus is conspicu- 
 ously longer than any of those which follow it. Their 
 rostra, too, are usually a trifle longer, and relatively a 
 little less thickened, than in Microxylobius proper, with 
 the antennas implanted just perceptibly nearer to the apex ; 
 and in the typical members of the group (the A. armatus, 
 conicollis, and monilicornis) the two hinder femora are 
 furnished with an acute spine at the base of their upper 
 edge. In the four remaining species which have as yet 
 been detected (namely the terebrans, obliteratus, debilis, 
 and angustus) the femora are unarmed. The A. moni- 
 licornis, however, presents a slight exception as regards 
 its funiculus-joints, the last four of which are almost of 
 equal length and breadth, the first of them being scarcely 
 at all elongated ; but in every other respect it is typical. 
 
 23. MICROXYLOBIUS (Chevrolat, Trans. Ent. Soc. Lond. 
 i. 98. 1836). A more careful examination of the many 
 remarkable and dissimilar Cossonids, from St. Helena, 
 which I have hitherto recorded (chiefly on account of their 
 funiculus being 5-articulate) as Microxylobii, has con- 
 vinced me that it will be better (indeed perhaps necessary) 
 to treat them as exponents of two distinct genera, or, if 
 we include the comparatively gigantic " M. cossonoides" 
 (which was enunciated by myself, as such, two years ago), 
 of three. As thus restricted, the dark and almost un- 
 metallic members of the group will be the Microxylobii 
 proper, in which moreover the surface, instead of being 
 highly polished and perfectly bald, is subopake, more or 
 less roughened, and with a tendency to be sparingly 
 studded with a very minute pubescence (which, however, 
 is sometimes barely traceable even beneath a high magni- 
 fying power). In fact, although distinct in the M. vestitus, 
 and just appreciable in the lacertosus and dimidiatus, this 
 pubescence may be said in the Westivoodii and lucifugus 
 to be almost, if not indeed entirely, absent. These five 
 species moreover, with the exception of the last, are the 
 smallest of the assemblage, and have their rostra relatively 
 a trifle broader and thicker (it being in some instances 
 almost subtriangular), and the second articulation of their 
 funiculus hardly at all longer than those which follow it. 
 In the excessive brevity of their metasterna, Microxylobius, 
 Acanthomerus, Lam.prochrus, and Amaurorrhinus are 
 nearly coincident ; though perhaps it is in Microxylobius 
 that it is more particularly shortened. 
 
522 Mr* T. Vernon Wollaston on the 
 
 24. MICROTKIBUS (nov. gen.). The very remarkable 
 little Cossonid for which the present genus has been 
 established is from the collection of Mr. Pascoe, and was 
 captured by my nephew, Captain F. W. Hutton, in the 
 Waikato district of North Island in New Zealand ; and 
 it is peculiarly interesting as adding another well-defined 
 type to the escutellate section of the Pentarthrides in which 
 the eyes are nevertheless fully developed. In its fusiform 
 outline, dark-piceous hue, slightly shining surface, and 
 rather shortened, subconcave metasternum, it is in entire 
 accordance with most of the immediately-allied genera ; 
 but it is conspicuous for its rostrum being rather narrow, 
 elongated, and parallel, for its eyes (although small) being 
 prominent and less wide apart from each other than is 
 usual, for its prothorax being oval, regularly rounded at 
 the sides, and largely developed, and for the second joint 
 of its exceedingly lax funiculus being very appreciably 
 lengthened, and the third one of its feet much expanded 
 and deeply bilobed. But one of its most significant 
 features "consists in the fact that, whilst the rest of its 
 body is completely bald, the base of its elytra and the 
 extreme hinder margin of its prothorax are studded, in 
 unrubbed specimens, with a few very fine, elongated hairs, 
 thus feebly shadowing-forth what is so strongly ex- 
 pressed in the nearly-blind Pentatemni (of the Atlantic 
 archipelagos), and still more so in Halorhynchus (from 
 western Australia), the anomalous Onyclwlips (of the 
 Canarian group), and the Madeiran genus Lipommata, 
 the last three of which are totally devoid of sight. 
 Whether however it at all indicates (as I am rather 
 inclined to suspect) a sand-infesting mode of life, as it 
 clearly does in the groups to which allusion has just 
 been made, I have no positive information. The exact 
 position of Microtribus, amongst the various forms which 
 up to the present time have been made known, appears to 
 be between Micro xylobius, from St. Helena, and Mesoxe- 
 nomorphus from southern Africa. 
 
 It has given me great pleasure to name the type of this 
 interesting genus after Captain Hutton, to whose inde- 
 fatigable researches we are gradually becoming indebted 
 for a more complete knowledge of the New Zealand fauna 
 than has hitherto been brought to light. 
 
 25. MESOXENOMOEPHUS (nov. gen.). The three ex- 
 amples for the reception of which I have been compelled 
 
Genera of the Cossonidce. 523 
 
 to establish the present genus have been communicated by 
 Mr. Janson, and are from British Caffraria in southern 
 Africa. In their fusiform outline, piceous hue, shining, 
 unpubescent surface, and obsolete scutellum, they are at 
 first sight very similar to Mesoxenus (now merged into 
 Amour or rliinus) ; nevertheless the fact of their eyes 
 (although minute) being present, instead of obsolete, 
 throws them into a different, though proximate, section 
 of the Pentarthrides. And, when closely inspected, they 
 will be seen, further, to recede from Amaurorrhinus, not 
 only in their relatively narrower body and more elongated 
 prothorax and elytra, but likewise in their shorter, broader 
 and more parallel rostrum, into which their very much 
 more abbreviated antennas are implanted further from the 
 apex, in their legs (the front and hind pairs of which are 
 a trifle more approximate at their respective bases) being 
 also shorter, in their metasternum being appreciably more 
 elongated, and (together with their first abdominal seg- 
 ment) less scooped-out, or concave, and in the third joint 
 of their feet being more decidedly simple. 
 
 26. HETEROPSIS (nov. gen.\ I am indebted to Dr. 
 Sharp for the remarkable little Cossonid for which the 
 present genus is proposed, and which was captured at 
 Auckland in New Zealand by Mr. Lawson, after whom 
 I have had much pleasure in naming the species. Its 5- 
 jointed funiculus and obsolete eyes (which are minute, 
 sunken, and very rudimentary) place it near to Amauror- 
 rhinus ; nevertheless it differs from the latter, and the 
 cognate forms, in having a developed scutellum ; whilst 
 in its extremely short and broad rostrum (particularly of 
 the male sex), which is a little contracted posteriorly and 
 is divided from the head by a distinct frontal line, and its 
 abbreviated, abruptly-clavate scape, it possesses features 
 which are essentially its own. In other respects, Hete- 
 ropsis is conspicuous for its small size, and its narrow, 
 cylindrical, but somewhat depressed body, for its shining, 
 piceo-castaneous surface (which is very lightly sculptured 
 anteriorly), and for its rather short legs and elongated 
 metasternum. 
 
 27. AMAURORRHINUS (Fairmaire, Ann. de la Soc. Ent. 
 de France, 629. I860). Although the exceedingly short 
 and imperfect diagnosis which M. Fairmaire has given of 
 
 TRANS. ENT. SOC. 1873. PART IV. (OCT.) P P 
 
524 Mr. T. Vernon Wollaston on the 
 
 this genus does not call attention to a single structural 
 peculiarity beyond the fact that its fimiculus is composed 
 of but five joints, I have nevertheless, no hesitation in 
 identifying it with my Mesoxenus (from the Madeiran and 
 Canarian archipelagos), seeing that his specific description 
 of the type, namely the A. Bonnairii (= A. narbonnensis, 
 Bris.), from Corsica and the south of France, seems to 
 accord so well with an insect now before me, from Corfu, 
 which is unquestionably a Mesoxenus, as to leave little 
 doubt in my mind that it is even the actual species referred 
 to by Fairmaire. This particular example has been com- 
 municated by Mr. Janson ; and it is so closely allied to 
 the Mesoxenus Bewickianus, from Madeira, that I had at 
 first sight imagined it must be identical with it. A more 
 critical inspection however has convinced me that the two 
 are specifically distinct, though it is impossible to have the 
 slightest hesitation in assigning them to at all events the 
 same group ; and I do not think, therefore, this being the 
 case, that Mesoxenus should be kept apart from Amau- 
 rorrhinus. Nevertheless I ought perhaps to mention that 
 Fairmaire makes no allusion whatever to the obsoleteness 
 of its eyes, which is the most important feature in the 
 insects now before me ; and that he likewise speaks of the 
 antennas as " in medio rostri insertas," whereas those organs 
 are implanted considerably before the middle in the only 
 three representatives of my genus Mesoxenus which I have 
 hitherto examined. Still, the manifest looseness, and 
 brevity, of his diagnosis is sufficient to account for these 
 omissions; and it is my belief, as just stated, that the 
 genera in question are identical.* 
 
 Regarding therefore the Amaurorrhini and Mesoxeni 
 as coincident, I may add that the members of this genus 
 have the bald, rufo-castaneous, and slightly shining surface 
 of Pentarthrum ; nevertheless their obsolete eyes and 
 scutellum, and abbreviated metasternum, throw them into 
 a totally different section of the present subfamily. They 
 
 * In size, colour, outline and sculpture, the species from Corfu (which I 
 believe to be the A. Bonnairii of Fairmaire) almost exactly resembles the 
 Madeiran A. Heivickianus, from which it merely differs in its prothorax 
 being a little less widened (or rounded-outwards) behind the middle, in its 
 rostrum being just appreciably slenderer and less expanded in front of the 
 antennae (which are themselves not quite so thick), in its second funiculus- 
 joint being perhaps a trifle more elongate (though not so much so as in the 
 A. Monizianus), in its club being somewhat less developed, and in its 
 metasternum and first abdominal segment being more convex (or hardly 
 at all scooped-out, or concave). 
 
Genera of the Cossonida. 525 
 
 are also more fusiform, or less parallel, insects than the 
 Pentarthra ; their prothorax is more rounded and convex ; 
 their elytra are less straightened, and more lightly sculp- 
 tured ; their rostrum is a little longer and less robust ; 
 and their antennae (which are implanted a trifle nearer to 
 the apex of the latter) have their scape slenderer and 
 more curved. There is also a peculiarity about their 
 undersides (which is likewise the case in most of the 
 Microxylobii and Acanthomeri, as well as in Lampro- 
 chrus, and in many of the true Cossonides), the first 
 abdominal segment and the (very short) metasternum being 
 deeply impressed (at any rate in the two Atlantic-island 
 species) down the central region, causing them to be 
 hollowed-out, or concave. Two out of the three Amau- 
 rorrhini with which I am acquainted (namely the A. 
 Monizianus and Bewickianus) are found in the 1 Madeiran 
 archipelago, and one of them likewise at the Canaries, 
 whilst the other occurs in the south of Europe ; but the 
 slight singularity in their modes of life, which appear to 
 be much the same as those of Pentarthrum (as well as of 
 Hexarthrum, of the true Cossonides), renders it probable 
 that they will be found eventually to possess a more ex- 
 tended range. 
 
 28. PSEUDOMESOXENUS (nov. gen.\ The little insect 
 (hitherto unique) for the reception of which the present 
 genus is established was taken in the island of St. Helena 
 by Mr. Melliss ; and it was recorded by myself, three 
 years ago, as a blind, aberrant Pentarthrum, under the 
 name of P. subccecum.* It is evident however that it has 
 a far closer affinity with Amaurorrhinus, with which 
 indeed its obsolete eyes and scutellum, and its convex, 
 largely-developed prothorax, would tend to affiliate it. 
 Still, an accurate examination of its structural details has 
 convinced me that it cannot be treated as even an Amau- 
 rorrhinus ; for not only is its metasternum very appreci- 
 ably more elongated, and its rostrum thicker and sub- 
 triangular, but its elytra likewise are narrower and more 
 parallel and cylindrical, and its limbs are shorter and less 
 thickened, the feet especially being slenderer and filiform, 
 with their third joint almost unexpanded and simple. 
 The underside moreover is convex, and has no trace of 
 the concavity which gives so remarkable an appearance to

 29. PENTATEMNUS (Wollaston, Trans. Ent. Soc. Lond. 
 2nd ser. v. 385. 1861). In its obsolete scutellum and eyes 
 (the latter of which are very minute and indistinct, being 
 composed of only about six small lenses), and its dark 
 piceous hue, and the fact of its funiculus being 5 -articulate, 
 Pentatemnus agrees with Ama.urorrhinus ; but it differs 
 from it essentially in most of its other details, as well as in its 
 subfossorial mode of life. Thus, not only is its body (in- 
 stead of being bald) sparingly studded with elongate silken 
 hairs, but its elytra and under-surface are curiously and 
 thickly asperated with obliquely-impinged punctures, its 
 rostrum and antennae (the former of which is more strictly 
 parallel, and the latter are more medially inserted) are 
 much shorter and thicker, its legs are considerably more 
 incrassated, and its third tarsal joint is simple. Its tibial 
 hooks too are very much more developed, the four hinder 
 ones being exceedingly powerful, and rather expanded, and 
 compressed, at their base, causing the tibias to seem as 
 though slightly rounded-outwards at their external angle. 
 The Pentatemni are sand-infesting, and somewhat fossorial, 
 in their habits (as indeed their pilose bodies, obsolete eyes, 
 and strongly-developed legs and tibial hooks would par- 
 tially imply), residing around the roots of shrubby plants 
 which stud the arid tracts of loose, drifting sand in certain 
 islands of the Canarian and Cape- Verde archipelagos, 
 where they often descend to a considerable depth beneath 
 the surface. In such situations I have met with them in 
 Lanzarote, Fuerteventura and Grand Canary of the for- 
 mer, and in Sao Vicente of the latter. 
 
 30. HALORHYNCHUS (nov . gen.). The insect for which 
 the present genus has been proposed is from the collection 
 of Mr. Pascoe, by whom it was received from Freemantle 
 in Western Australia ; and it is perhaps the most impor- 
 tant of all the forms which he has communicated to me, 
 as establishing most completely the manifest relationship 
 which exists (of which, despite the opinion of Lacordaire, 
 I have never myself entertained the slightest doubt) be- 
 tween the Pent artlir ides and that singular department of 
 aberrant, fossorial Cossonids, to receive which I have 
 established the subfamily Onycholipides. Indeed so much 
 has it in common with Onycholips (with which it also 
 
Genera of the Cossonidcp. 527 
 
 agrees in its total freedom from even the rudiments of 
 eyes) that I had at first sight supposed it to be a member 
 of that actual genus ; nevertheless its 5-jointed funiculus, 
 parallel outline and obsolete scutellum, in conjunction with 
 its less completely approximated four anterior legs and 
 the structure of its abdominal segments and tibias, show it 
 to belong unmistakeably to that particular section of the 
 Pentarthrides which contains Pentatemnus. In point of 
 fact it is very intimately allied to the latter genus, from 
 which it nevertheless recedes in its eyes being altogether 
 absent, in its tibiae being armed at their inner angle (as in 
 Lipommata) with a distinct spinule, and in the two hinder 
 ones having their apical hook reduced in size and almost 
 spiniform, in its four anterior tarsi being more narrow and 
 linear, whilst the hinder pair are comparatively robust, and 
 in its claws being so exceedingly minute as to be barely 
 traceable even beneath the microscope. In its general 
 outline and sculpture, as well as in its rather pallid hue, it 
 is exactly intermediate between Pentatemnus and Ony- 
 cholips,si fact which is equally borne-out by its nearly 
 rudimentary ungues, and the somewhat spiniform struc- 
 ture of its hinder tibial unci. 
 
 In its prothorax being appreciably narrower than the 
 elytra, as well as in its inner tibial angle being produced 
 into a very evident, robust spinule, and in its eyes being 
 totally absent, Haloryhnchus embodies some of the most 
 characteristic features, likewise, of Lipommata (in the true 
 Cossonides}, thus bearing still further testimony to that 
 strange and mysterious resemblance which seems, as it 
 were, to bind together the whole of these immediate pilose, 
 posteriorly-asperated, fossorial, sand-infesting forms, in the 
 three subfamilies Pentarthrides, Onycholipides, and Cos- 
 sonides. 
 
 31. GEORRHYNCHUS (Eoelofs, Ann. Soc. Belg. x. 241. 
 1866 ; and xi. 78. 1867). I am indebted to M. Eoelofs, 
 of Brussels, for the opportunity of examining his unique 
 type of the very curious insect (captured near Montevideo, 
 in South America) for the reception of which he established 
 the present genus ; and although I will not venture to re- 
 cord more than a desultory opinion concerning its affinities, 
 which Lacordaire (vide Gen. vii. 348, note) and others 
 have justly regarded as very obscure ; yet, after a careful 
 examination of its several parts, I cannot but think that it 
 
528 Mr. T. Vernon Wollaston on the 
 
 is perhaps more correctly placed at no great distance from 
 the equally anomalous group Onycholips than in any other 
 situation with which I am at present acquainted. And if 
 it can be shown that the subfamily Onycholipides is its 
 true status, there can be but little doubt (despite the 
 anomalousness of its structure) that it is a veritable mem- 
 ber (although, like its immediate associates, an aberrant 
 one) of the Cossonida ; for Onycholips is so intimately 
 connected, on the one hand (through Halorhynchus and 
 Pentatemnus), with the Pentarthrides, and on the other 
 (by means of Raymondionymus, Alaocyba, and Lipom- 
 mata) with the Cossonides proper, that there is scarcely 
 room for question as to where, in any system of arrange- 
 ment which professes to be a natural one, it should be 
 stationed. 
 
 Although very differently modified, there is a remark- 
 able degree of correspondence between Georrhynchus and 
 Onycholips, not merely in the exact parts selected for 
 modification, but likewise, to a certain extent, even in the 
 kind of their development ; whilst in their subfossorial, 
 sand-infesting modes of life they appear to possess another, 
 and a very significant, point of union. Thus, in both 
 cases, the number of the funiculus-joints is reduced to the 
 very unusual one of six, and that of the tarsal ones to four ; 
 and both genera are almost equally conspicuous for their 
 comparatively pale, hairy, convex, and slightly asperated 
 bodies ; for their greatly abbreviated antennas, rostra, and 
 metasterna; and for their tibiae (although different in 
 detail) being on a compressed and burrowing type, and 
 moreover (which is of the utmost importance) free from 
 an apical hook. In each instance, too, the scutellum is 
 distinct, and (which is especially to be noted) the front 
 coxae are contiguous and the intermediate ones but barely 
 separated. It is true that the eyes and claws, which are 
 absent in Onycholips, are present in Georrhynchus ; but 
 that may indicate a mere generic difference, such as we 
 see paralleled in other groups of the Cossonidce which are 
 universally admitted to be in juxta-position ; and I think 
 therefore that enough has been said to render it at least 
 probable that the two genera in question are not very 
 remote, as regards the several peculiarities of their struc- 
 ture, from each other. And if this fact can be but once 
 established, it seems to me that we have then sufficient 
 evidence to show (as may be gleaned from my observations 
 
Genera of the Cossonida. 529 
 
 under Onycholips and the following groups) that the true 
 position of Georrhijnchus must be, of necessity, amongst 
 the Cossonids. 
 
 32. ONYCIIOLIPS (Wollaston, Trans. Ent. Soc. Lond. v. 
 389. 1861). It was not without some degree of hesitation 
 in the first instance, that I decided on recognising the 
 anomalous genus Onycholips as the type of a subfamily 
 of the Cossonidce; more especially since Lacordaire has 
 expressed a doubt as to its true location, and hints that 
 it may perhaps be necessary to establish a distinct family 
 of the Rhynchophora to receive it, along perhaps with 
 Georrhynchus (the almost equally unintelligible Curcu- 
 lionid just alluded to, with apparently somewhat similar 
 subfossorial habits, detected at Montevideo). Yet, de- 
 spite its many eccentricities, some of which would seem to 
 debar it from nearly every department of the weevils which 
 has hitherto been defined (and which must remain, con- 
 sequently, anomalies wherever the genus be placed), the 
 more I study its various details (structural and external), 
 and its fossorial mode of life, the more convinced am I, as 
 at first, of its not very distant relationship with such blind 
 members of the Cossonidce as Pentatemnus, Halorhynchus, 
 and Lipommata (particularly the former), and even more 
 so perhaps with the equally blind Raymondionymus and 
 Alaocyba, all of which have either burrowing or sand- 
 infesting habits, and slightly pilose bodies, and which show 
 some kind of tendency for unusual tibial developments; the 
 last two, moreover, having a 6-jointed funiculus, and 
 quadriarticulate feet. Perhaps the most significant points 
 however, which have been urged as tending to remove it 
 from the Cossonidce are embodied in the twofold fact that 
 its first and second abdominal segments are not completely 
 soldered, and that its intermediate coxas are almost (like 
 the anterior ones) contiguous ; but, on the other hand, 
 there are many undoubted Cossonids in which the first 
 and second segments of the abdomen are not absolutely 
 confluent, being (as in Hexarthrum, Brachytemnus and 
 Sphcerocorynes) separated from each other by a most con- 
 spicuous sutural line ; whilst certain, also, of the sub- 
 Hylastideous genera of the true Cossonides have (like 
 Hexarthrum, Stereocorynes, Tomolips, Brachytemnus, 
 Stenoscelis, and others) their intermediate legs (no less 
 than their anterior ones, almost completely in contact, and 
 I think therefore that neither of those characters will- 
 
530 Mr. T. Vernon Wollaston on the 
 
 suffice, of itself, to exclude a manifestly erratic form like 
 Onycholips from being regarded as the type of a new 
 department of the present family, the exponents of which 
 are thus anomalously (though variously) modified. 
 
 Apart from its totally blind condition, its 6-jointed funi- 
 culus* and quadriarticulate feet, as well as from the fact 
 of its anterior coxas being entirely and its intermediate 
 ones almost contiguous, and its apparent freedom from 
 tarsal claws, Onycholips is at once remarkable for its 
 rather globose and testaceous body, which is sparingly 
 beset with exceedingly long silken pile, and the surface of 
 which is somewhat uneven (being marked, or pitted, with 
 large but shallow varioles, or irregular punctiform impres- 
 sions) and slightly asperated, for its rostrum being short, 
 broad, depressed, and subtriangular, for its scutellum being 
 distinct, and for its antennae and legs being greatly abbre- 
 viated. Indeed, the former are of a most curious struc- 
 ture, their scape being so reduced in length as to be 
 absolutely concealed within the short and deep auriculiform 
 scrobs ; whilst its funiculus has the first two (I) articula- 
 tions very largely and subequally incrassated, with the 
 remaining four minute ; and their club is extremely solid, 
 and apically-pilose. And the latter, which are very short 
 (especially as regards their femora), are still more extra- 
 ordinary, the two front tibise being produced at their 
 outer angle into an exceedingly elongated, tectiform lobe 
 (which represents the ordinary hook) ; whilst the four 
 hinder ones are powerfully developed, and spinulose along 
 their exterior edge, and compressed at each of their angles 
 (inner and outer) into a small obtuse lobiform plate, 
 between which the feet are implanted. These latter are 
 on a pattern which is quite without precedent in any 
 Coleopterous insect with which I am acquainted : for 
 while the anterior pair are abnormally shortened, narrow, 
 filiform, and quadri-articulate (the fifth joint being appa- 
 rently lost, and the fourth, or terminal, one being sur- 
 mounted by a tuft of elongate pile as though to represent 
 the ungues), the remaining ones have their basal joint 
 abbreviated, the two following produced into a divaricating 
 spiniform lobe at each of their angles, and the fourth, as I 
 believe, minute and completely soldered to, or merged into, 
 the fifth (which, like those which precede it, is apically- 
 
 * Lacordaire, in his ' Genera' (vide vii. 347), has inadvertently recorded 
 Onycholips as possessing a 7 -jointed funiculus. 
 
Genera of the Cossonidcc. 531 
 
 divaricate), the two together thus constituting a single 
 joint, bifurcated at its tip. And from the analogy of the 
 similar (though more enlarged) lobes at the angles of the 
 joints which precede it, I conclude that these two terminal 
 diverging processes do not represent the claws (which seem 
 to be altogether absent), but rather the prolongations of 
 the anterior angles of the ultimate joint. 
 
 In its habits Onyclwlips appears to be much the same 
 as Pentatemnus and Lipommata, though more decidedly 
 fbssorial, its spinulose posterior tibia3 being eminently on 
 a burrowing pattern ; and it is still more conspicuously 
 beset (like so many sand-infesting insects), with remote, 
 elongated hairs. Indeed, these latter are not confined to 
 the body alone, both the scape and club of the antenna 
 being singularly pilose. I have captured it in the three 
 eastern islands (Lanzarote, Fuerteventura, and Grand 
 Canary) of the Canarian archipelago, where it resides 
 on, and beneath, the surface of the sandy hillocks, in the 
 vicinity of the coast, which have accumulated gradually 
 around the roots of the few shrubby plants which stud 
 those arid spots. 
 
 33. RAYMONDIONYMUS (== RAYMONDIA, pars, Aube, 
 Ann. de la Soc. Ent. de France, 195. 1861). The 
 blind and anomalous genus Raymond! onymus (or Ray- 
 ?nondia*), which appears to occur in Mediterranean lati- 
 tudes, has somewhat the fusiform outline, rather elongated 
 rostrum, and rufo-piceous hue of Amaurorrhinus ; but its 
 funiculus is composed of six articulations (instead of only 
 five), its metasternum is shorter still, its tibia3 (which have 
 no terminal hook) are compressed and triangularly dilated, 
 and its feet are short, broad, and thick, furnished with long 
 
 * I regret that it should be absolutely necessary to change the name of 
 this gcnns,"liaymondia" having been preoccupied by M. Frauenfeld, for 
 a group of the Diptera (vide Sitzungsb. d. Wien. Acad. xviii. 320), six years 
 before it was employed by Aube. In real fact, however, this is perhaps 
 the less to be deplored, since I strongly suspect (judging from the diagnosis 
 and figure) that Aube's R.fossor is not actually congeneric with the larger 
 species which have subsequently been associated with it, but more properly 
 with Alaocyba, as recently enunciated by Ferris ; and if this should be the 
 case, it follows that the larger species, of which I would regard the R. Mar- 
 quetl as the type, have not yet been separated generically from the smaller 
 ones. Be this however as it may, the title " Ilayniondia" must of neces- 
 sity be altered ; and therefore, being unwilling to disconnect the group 
 with the name of the eminent Coleopterist to whom it was originallv dedi- 
 cated, I have (rather than take the opposite alternative) proposed for it, 
 instead, the perhaps not altogether euphonious one of Baymondionymiis. 
 
532 Mr. T. Yernon Wollaston on the 
 
 hairs beneath, and (instead of being on the ordinary pseu- 
 dotetramerous type) strictly four-jointed. Its sculpture 
 is very peculiar, the punctures (which are lighter towards 
 the apex of the elytra) being exceedingly large and few in 
 number (somewhat after the fashion of what obtains in 
 Onycholips); its rostrum (as in Alaocyba and Lipom- 
 mata) is appreciably, and gradually, narrowed in the 
 middle ; its surface, although appearing at first sight to 
 be quite bald, will be seen beneath a high magnifying 
 power to be studded (at any rate behind) with a few short 
 bristles ; and its legs are eminently fossorial, and greatly 
 incrassated, the triangularly expanded tibiae being deeply 
 scooped-out, or emarginate, towards their external angle, 
 the excavation being more or less filled-up, or pectinated 
 (at any rate in the posterior ones), with strong cilice, or 
 bristles. Its antennas (which are elongate, and almost 
 terminal as regards their insertion) have the second joint 
 of their funiculus perceptibly, though slightly, longer than 
 those which follow it, and their club excessively large, 
 abrupt, and distinctly annulated ; and its tarsal claws are 
 considerably developed. The concave, or longitudinally 
 impressed, structure, also, of its first and second abdominal 
 segments should be noticed ; but this I think has been 
 made too much of as a peculiarity, since the same feature 
 exists (more or less expressed) not only in Alaocyba, but 
 likewise in several genera of the Pentarthrides, such as 
 Amaurorrhinus, Microxylobius, Acanthom,erus, and Lam- 
 prochrus ; and we also find it in Cotaster, of the true 
 Cossonides. In no genus, however, that I have yet 
 examined, is the concavity so deep, and so well defined, 
 as it is in Raymondionymus. In their modes of life the 
 species of Raymondionymus seem to be in entire accord- 
 ance with the members of the present curious subfamily, 
 their compressed, dilated, setulose, apically unarmed tibiaa 
 indicating fossorial habits ; whilst their total freedom from 
 eyes would tend still further to imply a partially subter- 
 raneous propensity. And it is not surprising therefore 
 that the few which have hitherto been brought to light 
 (principally in the south of France) should have been met 
 with in such situations as beneath stones deeply imbedded 
 in the soil, within crevices of clay, and in the nests of 
 ants. I should add that the particular species from which 
 my diagnosis is compiled, and for a type of which I am 
 indebted to John Gray, Esq., is the R. Marqueti, Aube, 
 from Narbonne. 
 
Genera of the Cossonidce. 533 
 
 34. ALAOCYBA (Ferris, in Abeille, vii. 31. 1870). 
 I am indebted to Dr. Sharp for a type of the very rare 
 genus Alaocyba, namely the diminutive A. carinulata^ 
 which was taken by M. Raymond in Sardinia ; and, after 
 a very careful inspection of its details, I feel satisfied that 
 it is truly distinct from Raymondionymus as represented 
 by the larger species which have been referred to that 
 group, though I am less convinced that it differs generi- 
 cally from the smaller ones which are equally cited as 
 Raymondice (or Raymondionymi). Indeed one of them, 
 the " R. Delarouzeei" which has been communicated by 
 John Gray, Esq., appears to me to possess all the essential 
 characters of Alaocyba, as contradistinguished from Ray- 
 mondionymus ; and I have no hesitation therefore in 
 regarding it as pertaining to the former, rather than to the 
 latter ; and it is not unlikely that one or two of the others, 
 when properly overhauled, may prove to be Alaocybce. 
 Be this however as it may (for I have had no opportunity 
 of examining them), I consider the carinulata and Dela- 
 rouzeei as at any rate belonging to Alaocyba, and the 
 much larger, darker, and in many respects differently 
 constructed, Marqueti as a Raymondionymus proper ; 
 and it is on this understanding that I have compiled my 
 diagnoses of the two groups. 
 
 As thus defined, Alaocyba may be said to differ from 
 Raymondionymus in the much smaller size, extremely 
 pallid hue, and more depressed (and perhaps rather more 
 setulose) bodies of the insects which compose it, in which 
 moreover the sculpture is less coarse (particularly in the 
 A. carinulata, which must be regarded as the type), the 
 prothorax is furnished with a more evident medial line, or 
 keel, and tbe elytra are free from the cariniform structure 
 (on either side) towards their apex. And, moreover 
 (which is of greater importance still), the funiculus joints 
 are more decidedly moniliform (the second one being as 
 short and rounded as those which follow it), the legs are 
 less thickened, and the tibiae are less broadly dilated, 
 especially the front pair, which are not scooped-out like 
 the other four towards their external apex, but merely a 
 little truncated. The rostrum, too, is proportionately not 
 quite so elongate ; and in the A. carinulata the antennas 
 are implanted a trifle further from its apex. In their 
 habits the Alaocybce appear to be very similar to the 
 Raymondionymi, the structure of their compressed tibiaa, 
 although a little less strongly pronounced, being eminently 
 
534 Mr. T. Yernon Wollaston on the 
 
 fossorial. The A. carinulata, which (as just stated) is 
 the type of the genus, was detected by M. Raymond in 
 Sardinia. 
 
 35. LIPOMMATA (Wollaston, Cat. Mad. Col. 100. 1857). 
 In the relative length and shape of its (nevertheless 
 thicker) rostrum, which (instead of being quite parallel) is 
 rather contracted in the middle, as well as in its total 
 freedom from eyes, its sparingly pilose surface, obsolete 
 scutellum, and subfossorial mode of life, Lipommata has 
 manifestly more in common (despite its comparatively large, 
 convex, Phloeophagits-[ik.Q body) with Raymondionymus 
 and Alaocyba of the preceding section (in which neverthe- 
 less the funiculus is 6-jointed, the feet quadriarticulate, 
 and the tibial hook absent) than Cotaster has ; and there- 
 fore I have given it the first place in the Cossonideous 
 division of the family ; though at the same time it is true 
 that in Cotaster the greatly abbreviated metasternum, un- 
 even prothorax, and prim d facie aspect would indicate a 
 considerable affinity with those two genera. In reality, 
 however, I believe that Lipommata is still more closely 
 connected with the (equally subfossorial) Pentatemnus , of 
 the Pent artlir ides, which it greatly resembles, both in 
 appearance and habits ; but, not to mention other points 
 of dissimilarity, that genus has the funiculus only 5- 
 (instead of 7-) articulate, and the eyes (instead of being, 
 as in Lipommata, altogether wanting) merely obsolete. At 
 first sight, indeed, Lipommata might almost be regarded 
 as a blind Phloeophagus, so greatly does its ovate outline, 
 obsolete scutellum, and convex, pilose surface, agree with 
 certain members of that group : nevertheless its total free- 
 dom from eyes, its minutely asperated, basally-subemar- 
 ginate elytra (the shoulders of which are, consequently, 
 somewhat unusually porrect), and its rather differently- 
 developed tibiae, will of themselves at once separate it from 
 the PhlcBophagi. The single exponent of it which has 
 hitherto been brought to light seems to possess the same 
 sand-infesting propensities as Pentatemnus and Onycho lips; 
 it having been detected by myself in the Madeiran archi- 
 pelago, where it occurs about the roots of certain plants 
 (often at a considerable depth beneath the surface), on the 
 sandy slopes behind the sea-beach, in the island of Porto 
 Santo. It is the only true member, so far as I am aware, 
 of the subfamily Cossonides, in which the organs of sight 
 are completely wanting. 
 
Genera of the Cossonidce. 535 
 
 36. STrniLODERES (nov. gen. ; COTASTER, Mots., 
 pars). In its exceedingly abbreviated metasternum, 
 obsolete scutellum, and elongated antennse (which are 
 implanted considerably before the middle of the rostrum), 
 as well as in its more or less pallid hue and subelliptical 
 elytra, Styphloderes has much manifestly in common with 
 Raymondionymus and Alaoci/ba, of the preceding sub- 
 family ; nevertheless it differs very essentially from them 
 both, not only in its much larger size, and in its funiculus 
 being 7- (instead of 6-) articulate, but likewise in its eyes 
 being developed, and in the structure of its much longer 
 legs, the tibiaa of which (instead of being spinulose, com- 
 pressed, fossorial, and apically unarmed) are elongate, 
 narrow, and (as in all the Cossonida except the Notio- 
 mimetides and the Ony cholipides) uncinated at their outer 
 angle ; whilst the feet, instead of being simple and quadri- 
 articulate, are on the ordinary pseudotetramerous type, 
 the third joint being expanded and bilobed, and the fourth 
 one minute and hidden. With these most important dis- 
 crepancies, it seems to me quite impossible (despite the 
 opinion of Lacordaire) to admit Styphloderes into the 
 same actual section as those two genera ; yet I have never- 
 theless acknowledged the points of agreement between the 
 three (which consist mainly in their much-abbreviated 
 metasternum and pallid hue) by placing them almost in 
 juxta-position, namely at the end and nearly at the 
 beginning, respectively, of two distinct subfamilies. In 
 its mode of life, no less than in its structural details, 
 Styphloderes does not appear to be fossorial ; though it is 
 nevertheless stated by Motschoulsky (vide Guer. Rev. de 
 Zool. 427. 1851) to have been found beneath marine 
 rejectamenta on the sea-shore near Marseilles. It belongs 
 essentially to Mediterranean latitudes, having been captured 
 in the south of Europe and the north of Africa. 
 
 The only member of this genus with which I am 
 acquainted (viz. the exsculptus, Boh., or littoralis, Mots.) 
 has been hitherto associated with Cotaster; but if we are 
 to regard the Phlozopliagus uncipes, of Boheman, as the 
 type of the latter (and it is expressly stated to be so), it 
 seems absolutely necessary to propose an additional group 
 to receive the former, which differs essentially, in nearly 
 every one of its details, from the uncipes. Thus, not only 
 is it larger, and more pallid and depressed, but its rostrum 
 is relatively very much longer, and rather narrower, its 
 eyes are considerably smaller, its prothorax is uneven, 
 
536 Mr. T. Vernon Wollaston on the 
 
 tricarinated, and constricted in front (instead of being 
 convex and simple), its antennae are more elongated and 
 slender, inserted nearer to the apex of the rostrum, and 
 with the (less compact) funiculus-joints (especially the 
 second one) longer, its legs also (particularly as regards 
 the tibiae) are longer and thinner, and its feet have the 
 third articulation more evidently expanded and bilobed, 
 and the claws conspicuously more developed. The body 
 moreover, instead of being coarsely, though sparingly, 
 pubescent (with the pubescence developed on the elytra 
 into elongate, erect setae), is bald.* 
 
 37. COTASTER (Motschoulsky, Guer. Rev. Zool. 425. 
 1851). In primd facie aspect this is one of the most 
 remarkable genera of the Cossonidcs with which I am 
 acquainted; and, although European, it appears to be 
 somewhat scarce in collections. I am however indebted 
 to Mr. Gray and to Mr. E. "W. Janson for the opportunity 
 of examining several types which, judging from labels 
 which are appended to them, appear to have been 
 captured by M. Hampe in Croatia. Before an accurate 
 inspection, it has much the appearance of a small and 
 rather narrow Acalles, its convex, ovate body, and nearly 
 opake, reddish-brown surface (which is sparingly clothed 
 with decumbent fulvo-cinereous pile, which however is 
 developed on the alternate interstices of the elytra into 
 elongate erect bristles), giving it a character which is 
 strongly suggestive of certain members of that group. Its 
 rostrum is rather long and cylindrical ; its prothorax 
 (which is narrower than the elytra, at any rate than the 
 widest portion of them) is suboval, closely punctured, and 
 even (being scarcely at all constricted behind the apex) ; 
 its elytra are ovate and punctate-striated, with the inter- 
 stices convex and remotely studded (at any rate as regards 
 the alternate ones) with the elongate setas to which I have 
 above alluded; its antennas (which have their scape robust, 
 slightly curved, and considerably thickened towards the 
 apex, and their second funiculus-joint not at all lengthened) 
 are inserted a little before the middle of the rostrum ; its 
 legs are a good deal incrassated ; its claws are exceedingly 
 
 * I have had no opportunity of inspecting the citneipennis, Aube ; 
 but, judging from the diagnosis, my belief is that it will be found to be a 
 true Cotaster (and therefore congeneric with the uncipes), and not refer- 
 able to the group which I have established for the reception of the ex-

 minute ; its metasternum is very short, and the first seg- 
 ment of its abdomen is likewise more abbreviated than is 
 usually the case amongst the Cossonida. 
 
 [38. LYMANTES (Schonherr,G^w.<tf Spec. Cure. iv. 1085. 
 1838). The present genus, together with the two follow- 
 ing, I have not been able to inspect ; and consequently 
 the few diagnostic characters which are given of it in my 
 summary I cannot vouch for as being in precise accordance 
 with the type. It seems to have been founded on a single 
 species, from North America, the S. scrobicoltis, Bohm, 
 which is described as rather elongate and oblong, of 
 either a black or brownish hue, somewhat variolose an- 
 teriorly and beneath, and with the elytra (which are not 
 wider than the prothorax) deeply punctate-striate. Its 
 metasternum is much abbreviated ; its rostrum is robust, 
 and separated by a deep stricture from the forehead ; its 
 eyes are small and depressed ; its prothorax is elongate- 
 quadrate ; and its feet are short and filiform.] 
 
 [39. APAROPKION (Hampe, Wien. Ent. Monatsch. v. 
 68. 1861). As just stated, this genus (although Euro- 
 pean) I have not been able to procure for examination ; 
 and consequently I cannot speak with any precision con- 
 cerning the very few diagnostic features which I have 
 extracted concerning it from Lacordaire. Indeed even 
 the latter does not appear to have been acquainted with it 
 except through the very short and imperfect description 
 given by M. Hampe ; and we may presume therefore 
 that it is of great rarity in collections. It was established 
 to receive a small insect (the A. costatum] from Tran- 
 sylvania, which is said to be of a brownish colour and 
 finely pubescent, with the prothorax subglobose and much 
 narrower than the elytra (which latter are oval and con- 
 vex), the head minute, the rostrum (into which the an- 
 tennre are inserted towards the apex) rather long and 
 subcylindric, and the third tarsal joint bilobed.] 
 
 [40. OODEMAS (Boheman, Res. Eugen. 138. 1859). 
 This genus, like the two preceding ones, I have not been 
 able to inspect ; and my short diagnosis is, consequently, 
 a mere epitome of the one given by Lacordaire. It ap- 
 pears to have been founded by Boheman to receive a small 
 insect taken near Honolulu, in the Sandwich Islands; 
 which is described as regularly oval, glabrous, shining,

 first sight, according to Lacordaire, my Pentarthrideous 
 Acanthomerus conicollis, of St. Helena. It appears to be 
 very slightly sculptured anteriorly, but with the elytra 
 longitudinally punctured Uhe punctures being large in 
 front, but evanescent behind) ; its rostrum is said to be 
 short and cylindrical, with the antennas (which are slender) 
 inserted at about the middle point ; its anterior coxae are 
 but feebly apart, and the third joint of its feet is large and 
 bilobed.] 
 
 41. CAULOTRUPIS (Wollaston, Ins. Mad. 308. 1854). 
 In a paper which I published, in 1861, on the ' Atlantic 
 Cossonides,' I expressed a doubt (vide Trans. Ent. Soc. 
 Lond. v. 375) as to whether Caulotrupis should be re- 
 garded as more, in reality, than a slight geographical 
 phasis of Phlceophagus peculiar to the Madeiran archi- 
 pelago ; and Lacordaire, taking advantage of this hesita- 
 tion on my part, did not scruple to cite it ( Gen. des Col. 
 vii. 342) as absolutely identical with that group. Yet a 
 more critical inspection of it than I had formerly been able 
 to bestow has convinced me, as at first, that it will be 
 better to treat it as generically distinct, more especially 
 since the presence, at the same time, of Phlceophac/us 
 proper in the Madeiran islands would seem to imply that 
 it can scarcely be a local development, at all events, of 
 that widely-spread type. Moreover the Caulotrupides 
 play so important a part in the Rhynchophorous fauna of 
 Madeira, where they attach themselves principally to the 
 old and decaying stalks of various shrubby plants (though 
 a few of them occur likewise beneath the bark of timber 
 trees), that there is an additional advantage in keeping 
 them separate ; and it is with the greater satisfaction 
 therefore that I am able to detect certain structural cha- 
 racters which I cannot but think, however small when 
 taken separately into- account, must fully warrant, when 
 combined, my original conclusions with respect to them. 
 
 The Caulotrupides have a peculiar aspect, which, when 
 once seen, can scarcely fail to distinguish them, even 
 primd facie, from the Phlceophagi. Thus they are more 
 elliptical, or fusiform, in outline, much more lightly sculp- 
 tured (particularly as regards their prothorax), and have, 
 most of them, a greater or less tendency for a metallic 
 lustre, the terebrans, Chevrolatii and conicollis being 
 completely brassy. Yet, in spite of this, their surface 
 
Genera of the Cossonidce. 539 
 
 (which for the most part is perfectly bald) is more or less 
 alutaceous, being in some instances so conspicuously so as 
 to appear nearly opake. Their prothoraces are more or 
 less conical, and unmargined along the posterior edge, 
 their scutella are generally quite untraceable, their pro- 
 sternum is very distinctly carinulated behind the anterior 
 coxae, their legs are a little wider apart at the base than is 
 the case in the true Phlceophagi (the hinder pair being 
 especially remote), and the first joint of their feet is less 
 evidently elongated. 
 
 42. PHLCEOPHAGUS (Schonherr, Gen. Cure. iv. 1047. 
 1838). The genus Phlceophagus has often been a good 
 deal confused with Rhyncolus, certain species having been 
 assigned by different authors to either group according as 
 their rostra happened to be either slender or robust ; and 
 indeed if the gracility of that organ were their main dis- 
 tinguishing feature, it would perhaps be difficult to draw 
 a line of positive demarcation between the two, for there 
 are undoubted members of both genera which have their 
 rostrum narrow, and others which have it incrassated. 
 Yet on the average the rostrum is certainly both longer 
 and slenderer in Phlceophagus than it is in Rhyncolus. 
 There are other characters, however, which would tend 
 (according to the arrangement which seems to me to be 
 most natural for the Cossonides) to place the groups in 
 question far asunder ; and perhaps none is more important 
 than the presence or absence of a scutellum, which in 
 Phlceophagus is either altogether untraceable, or else is so 
 minute and punctiform as to be with difficulty detected. 
 The Phlceophagi also are more convex and ovate than the 
 Rhyncoli ; their prothorax is usually less developed, but 
 more rounded at the sides; their metasternum is appre- 
 ciably shorter ; their anterior coxae are more approximated 
 (indeed the front ones are nearly contiguous) ; and their 
 antennae and legs are slenderer, the former of which, 
 likewise, as well as the tarsi, are generally more lengthened. 
 The Phlceophagi moreover have the second joint of their 
 funiculus and the basal one of their feet longer than is 
 the case in Rhyncolus, and also the club of their antennas 
 more enlarged and annulated ; and their third tarsal arti- 
 culation is for the most part minutely bilobed, rather than 
 simple ; though this character, last mentioned, is, in both 
 genera, a variable one. The Phlceophagi are principally

 either dark or piceous, in hue (more often the former) ; 
 and some of them have a very faint brassy tinge ; and, 
 unlike the Rhyncoli, certain of the species (though by no 
 means the majority of them) are sparingly pubescent. 
 They appear to be widely distributed over the world ; 
 and although specifically few in number throughout 
 Europe, they are rather unusually dominant in some of 
 the islands of the Atlantic archipelagos.* 
 
 43. PSEUDOPHLCEOPHAGUS (nov. gen.}. This genus, 
 which is established to receive the Phlceophagus tenax 
 from Madeira and the Azores, combines in a remarkable 
 degree the structural peculiarities of Rhyncolus and 
 Phlceophagus, agreeing with the former in its more 
 parallel outline, less inflated body, and conspicuous (though 
 rather small, transverse, and sub-perpendicular) scutellum ; 
 but with the latter in its abbreviated metasternum, and in 
 its comparatively slender antennae and tarsi, the first of 
 which have (as in Phlceophagus) their second funiculus- 
 joint appreciably longer than those which follow it, and 
 their club enlarged and abrupt, whilst in the feet the basal 
 articulation is considerably lengthened, and the third one 
 minutely bilobed. In its greatly approximated anterior 
 coxae it is more on the Phlceophagus than the Rhyncolus 
 pattern, and in its sericeous surface it is likewise more in 
 accordance with (at any rate a certain section of) the 
 former ; but its coxas are, if anything, still less separated 
 than in even the Phlceophagi (the front ones being practi- 
 cally contiguous), whilst the minute keel, or lobe, of its 
 mesosternum (between the intermediate coxae) appears to 
 me to be more developed than in either of those groups. 
 Its type (the P. tenax) is a very common insect in the 
 higher elevations of Madeira, where it occurs in great pro- 
 fusion in the rotten wood, and beneath the bark, of old 
 trees, more particularly those of the laurel tribe ; and it 
 has been met with also in the Azorean archipelago. 
 
 * The European P. aneopiceus is a less typical member of the group 
 than the various other species which I have examined ; for not only does 
 it recede in outline from the latter, but it has also manifest indications of 
 a scutellum, which, although not very easy to be detected, is certainly 
 appreciable. Indeed, I am not quite sure that it would not be more natural 
 to admit it (along with the tenax, from Madeira and the Azores) into the 
 genus PseudopMceophagus ; nevertheless since the characters alluded to are 
 not very pronounced ones, I will not disturb it in its usually-received 
 position. 
 
Genera of the Cossonidce. 541 
 
 44. THAUMASTOPHASIS (nov. gen.\ It is for an insect 
 which was captured at Crawler in Southern Australia, and 
 which has been communicated by Mr. Pascoe, that the 
 present genus is proposed ; and so remarkable is it in 
 many of its structural details that I could at first scarcely 
 persuade myself that it was a member of the Cossonidce 
 at all. But since at least three other forms (outside the 
 anomalous subfamily Onycholipides\ namely Aorus, Lipan- 
 cylus, and Xenocnema, have the tibial hook obsolete, 
 and are nevertheless veritable Cossonids, vne at any rate 
 of its most significant features may be regarded as not 
 altogether unparalleled even in the present department of 
 the Rhynchophora. And certainly in Thaumastophasis 
 the tibial uncus is strictly " obsolete" (and not completely 
 absent), for, when examined beneath a high magnifying 
 power, its presence may readily be detected in the anterior 
 pair, and I am not altogether sure that I cannot recognize 
 traces of it in the four posterior ones likewise (though I 
 will not be quite positive on this point) ; whilst the fact of 
 its front coxas being contiguous, and the intermediate ones 
 but barely separated, is almost in exact accordance with 
 what we observe in Pseudophlceophagus, and which is like- 
 wise unmistakeably approached in even Phlceophagus 
 proper. 
 
 I need scarcely add that the affinities of Thaumasto- 
 phasis are extremely difficult; but, nevertheless, having 
 once decided that it is a veritable member of the present 
 family, I am inclined to think that it will be better to place 
 it near to Pseudophlceophagus than elsewhere, with which 
 (despite its many eccentricities) it agrees at all events in 
 the shape and proportions of its (rather thick and linear) 
 rostrum, and in its antennas being long and slender, as 
 well as in its body (although short) being parallel, seri- 
 ceous and convex, its metasternum much abbreviated, its 
 front coxae contiguous (or practically so) and the inter- 
 mediate pair but faintly apart, and in its feet (which how- 
 ever are considerably thicker) having their basal joint (like 
 the second one of the funiculus) appreciably lengthened, 
 and the third one (although very much more conspicuously 
 so) expanded and bilobed. 
 
 In other particulars Thaumastophasis is remarkable for 
 its perfectly enormous eyes (which however are not ex- 
 tremely prominent), for its slender and acuminated club, 
 for its prothorax (which is small, and very much narrower 
 than the elytra) being slightly uneven, or as it were

 for its legs being a good deal thickened, and for its body 
 being of a piceous hue, with the exception of the elytra 
 which are conspicuously paler, or of a clear rufo-testaceous. 
 
 45. HIMATIUM (nov. gen.}. In its narrow, parallel, 
 cylindric, but not very convex, body which is of a rufo- 
 piceous hue, and sparingly studded with elongate, partially- 
 erect, fulvescent hairs the interesting little Cossonid for 
 which the present genus is proposed, and which has been 
 communicated by Mr. Fry as having been received from 
 Malabar in southern India, will be easily recognized. Its 
 surface is slightly shining, and (with the exception of the 
 head, which is convex and almost free from punctation) 
 coarsely and very densely sculptured; its rostrum is 
 parallel, but nevertheless somewhat narrow and not very 
 elongate ; its eyes are depressed, and greatly separated 
 from each other, so much so indeed that they are barely 
 visible when the insect is viewed from above ; its antennae 
 (which are inserted just before the middle of the rostrum) 
 have their scape rather abbreviated, straight, and robust, 
 and their funiculus-joints (with the exception of the first 
 one), short, subequal, and submoniliform ; its pro thorax is 
 oval, and a good deal constricted in front ; its metasternum 
 is elongate ; its coxse (even the anterior pair) are wide 
 apart, and the third articulation of its feet is nearly 
 simple. 
 
 46. PHOLIDONOTUS (nov. gen.). I am indebted to 
 Mr. Pascoe for the loan of the somewhat obscure and in- 
 significant little insect (captured by Mr. Wallace at 
 Sarawak, in Borneo) to contain which the present genus is 
 proposed ; and, apart from its rather diminutive size, and 
 piceous, opake, densely-sculptured surface, it is remark- 
 able amongst the Cossonidce for being one of the very 
 few forms the surface of which is clothed (as in Pholido- 
 forus from Japan) with scales, some of them being coarse 
 and mud-like, and others thick, robust, and setiform. In 
 the inferior position of its depressed eyes (which are 
 scarcely visible when the specimen is viewed from above), 
 as well as in the structure of its rather long and narrow, 
 but straightened, rostrum, and in the fact of its surface 
 being piceous and (at any rate) clothed, I think there can 
 be little doubt that it displays a certain degree of affinity 
 with the Indian genus Himatium ; but, in addition to its 
 
Genera of the Cossonida. 543 
 
 squamose covering and smaller stature, its surface is more 
 opake and closely sculptured, its rostrum is relatively more 
 elongate and slender, its antennas are more medially in- 
 serted, its scutellum is much less developed, and its legs 
 are setose and proportionately thicker, with the posterior 
 coxae wider apart, and the third tarsal joint more evidently 
 bilobed. 
 
 47. COPTOKHAMPHUS (nov. gen.). The present genus 
 is founded on two species which have been communicated 
 by Mr. Pascoe (obtained, I presume, by Mr. Wallace), 
 one of them from Sarawak in Borneo, and the other from 
 Java. Its affinities are extremely difficult to determine ; 
 nevertheless I believe it to be a member of the Cossonidce, 
 and am inclined to think that the rather inferior position 
 of its transverse and greatly depressed eyes, in conjunction 
 with the fact that its rostrum is conspicuously divided 
 from the forehead, and its surface clothed, or setulose 
 (though in one of the representatives very sparingly so), 
 will tend to place it at no great distance from Himatium 
 an Indian genus (in the collection of Mr. Fry) from 
 Malabar. Yet its rostrum is considerably longer, slenderer, 
 and more curved than that of Himatium, and also very 
 much more separated from the head, the extreme base 
 being far more constricted than what we observe in the 
 groups around even Catolethrus; and its body, instead of 
 being pubescent, is more or Jess scaly and setulose. Cop- 
 torhamphus moreover is remarkable for many peculiarities 
 which are not indicated in any of the types with which I 
 have nevertheless considered it the most natural to asso- 
 ciate it. Thus, for instance, its funiculus (which has the 
 second joint appreciably elongated) is gradually much in- 
 creased in width, causing the club, although large, to be 
 by no means abrupt ; its front coxae are nearly, if not in- 
 deed altogether, contiguous (even more so than in Phlceo- 
 phagus)\ its femora are armed beneath with an acute 
 tooth ; its tibiae are greatly curved, and are furnished to- 
 wards their outer apex (more or less evidently), with a 
 pectinated tuft of setae ; and its prothorax has a large, 
 rounded, sharply-defined, and deep fovea just behind the 
 middle of the disk. This last-mentioned character is so 
 unusual, that I at first thought it must be the result of 
 accident ; but since it is conspicuous in both of the species, 
 I cannot but regard it as a generic eccentricity. 
 
544 Mr. T. Vernon Wollaston on the 
 
 48. APHANOMMATA (nov. gen.}. The insect which 
 constitutes the type of the present genus was taken by 
 myself, from out of rotten Euphorbia-stems, in the island 
 of St. Antonio of the Cape Verde archipelago ; and, to a 
 certain extent, it combines in a remarkable degree the 
 characters of Phlceophagus and Rhyncolus, agreeing 
 with the former in its comparatively slender limbs, and its 
 more elongated first tarsal and second funiculus joints, as 
 well as in the fact of its club being abrupt and its eyes 
 depressed ; but with the latter in its body being less con- 
 vex and more parallel, its rostrum shorter and thicker, its 
 scutellum conspicuous, and in the greater length both of 
 its metasternum and (more cylindrical) prothorax. It 
 possesses, however, many distinctive features of its own, in 
 which it recedes from both of those genera, such, for 
 instance, as the inferior position of its small and sunken 
 eyes (which are scarcely visible when the insect is viewed 
 from above), its narrower and more parallel outline, and 
 its greatly elongated metasternum ; in all of which respects 
 .it approaches far nearer to Himatium. And it is further 
 remarkable for its black, shining, and completely bald 
 .surface, for its triangular (though, at the same time, 
 
 somewhat e/oTz^afe-triangular) rostrum, for its transverse 
 scutellum, and for the third articulation of its exceedingly 
 long and slender feet being small and simple. 
 
 49. BRACHYSCAPUS (nov. gen.}. The affinities of this 
 curious genus (which is founded on an insect from Natal 
 which has been communicated by Mr. Fry) are somewhat 
 
 . obscure ; for while it possesses the short and triangular 
 rostrum, the rather approximated eyes, and the greatly 
 . abbreviated scape of certain of the sub-Hylastideous forms 
 , of the Cossonides, I nevertheless do not believe that it has 
 . in reality anything to do with those particular genera, 
 . its completely suffused first and second abdominal seg- 
 ments, and the exact degree of separation of its coxas, no 
 . less than the structure of its funiculus and elongate, 
 conspicuously annulated club, its external contour and 
 sculpture, and the shape and proportions of its prothorax 
 (which is regularly oval, and distinctly narrower than the 
 elytra), being all of them far more on the pattern which 
 obtains amongst the Phlceophagi. And moreover, when 
 we further consider that there is a considerable approach 
 to its peculiar shape of rostrum in the preceding genus, 
 Aphanommata (in which too the surface is shining, bald, 
 
Genera of the Cossonidce. 545 
 
 and of a deep black), and that a considerable reduction iii 
 the length of the scape is indicated (though to a less 
 extent) in Himatium, I feel satisfied that the position in 
 which I have placed it is a far more natural one than 
 amongst the (more or less asperated, posteriorly-obtuse) 
 types bordering on the Hylastidce. In addition to the 
 characteristics above mentioned, Brachyscapus has its 
 scutellum a good deal enlarged, and its under-wings 
 considerably developed. 
 
 50. PHLQEOPHAGOSOMA (Wollaston, Trans. Ent. Soc. 
 Lond. 23. 1873). The present genus is perhaps, on the 
 whole, somewhat less satisfactorily defined than most of 
 the others ; and I think it is far from unlikely that it may 
 be found eventually to include more than a single type of 
 form; yet, being unwilling to multiply genera unneces- 
 sarily, I have thought it better to treat it as admitting a 
 rather wider amount of structural variation than would 
 seem to be indicated in the neighbouring groups ; and we 
 may possibly therefore regard it, in this particular respect, 
 as somewhat analogous to Cossonus. It was established 
 by myself, originally, to receive two slightly discordant 
 species which had been collected by Mr. Gr. Lewis in the 
 Japanese archipelago ; and, if I am correct as regards the 
 material now before me, I might define it as embracing a 
 number of insects, sometimes a good deal differing from 
 each other, which have a wide inter-tropical range, and 
 which would seem, to at all events a certain extent, to 
 represent the Phl&ophagi and Rhyncoli of European lati- 
 tudes. Indeed a considerable proportion of them have, I 
 think, done duty for the former, and are consequently still 
 cited as such in the various catalogues ; but nevertheless 
 they cannot, strictly speaking, be associated with the 
 Phlceophagi, any more than they can with the Rhyncoli, 
 as interpreted by the structural features of the respective 
 (and universally-acknowledged) types of those two groups. 
 Thus, whatever be their discrepancies inter se, they recede 
 essentially from Phlceophagus in having a largely developed 
 scutellum, a comparatively elongate metasternum and pro- 
 thorax, and in the second joint of their funiculus, and the 
 basal one of their feet, being conspicuously more abbre- 
 viated. Moreover they are, on the average, much larger, 
 less ovate, and less convex, their rostrum is proportionately 
 more lengthened, and their four anterior coxae are wider 
 apart. 
 
546 Mr. T. Vernon Wollaston on the 
 
 From Rhyncolus, on the other hand, (with which they 
 agree better in their more separated coxae, more elongate 
 bodies, and developed scutellum), the members of Phlceo- 
 phagosoma differ in their very much slenderer and more 
 lengthened rostrum, in their less thickened and more 
 medially implanted antennae, which have a larger and 
 more abrupt club, and in their less prominent eyes. And 
 they are also larger than the Rhyncoli, and have their 
 anterior coxae (particularly however the intermediate pair) 
 rather more remote from each other, though these two 
 characters are less strongly expressed than they were as 
 compared with the corresponding ones of Phlceophagus.* 
 
 The species now before me, which I should regard as 
 pertaining to Phlceophagosoma, are from Japan, New 
 Zealand, the islands of the Malay archipelago, Malacca, 
 Ceylon, Malabar, and southern Africa. The one from 
 the last-mentioned of those regions (which has been com- 
 municated by Mr. Janson) has the name " Phlceophagus 
 ebeninus, Schon." appended to it, but it scarcely seems 
 to me to tally with the published diagnosis of that insect. 
 
 51. PHOLIDOFORUS (Wollaston, Trans. Ent. Soc. Lond. 
 18. 1873). The present genus was proposed in order to 
 receive a very singular Curculionid which appears to be 
 common in the Japanese archipelago, where it was de- 
 tected near Nagasaki, in the island of Kushiu, by Mr. G. 
 Lewis. It is at once remarkable amongst the Cossonida 
 for the thick, cinereous, bristle-like scales with which it is 
 densely studded, a type of clothing with which we are 
 very familiar in other departments of the Rhynchophora, 
 but which is of the rarest occurrence in the Cossonids. 
 In other respects it is conspicuous by its narrowish-fusi- 
 form outline (which is parallel in the middle, but much 
 attenuated both before and behind), for its rather elongated 
 antennas and feet, for its eyes being exceedingly prominent, 
 and for its third tar sal joint being a good deal expanded 
 and bilobed. 
 
 52. COPRODEMA (Wollaston, Trans. Ent. Soc. Lond. 
 20. 1873). Like the last genus, the present one was 
 
 * In the species of PJilceopJiagosoma, which I regard as the more typical 
 ones, the rostrum is of equal breadth throughout ; but in others it is either 
 (as in the P. curvirostris from Japan) a little thickened at the base, or else 
 (as in the P. fusirostris from New Guinea) slightly and gradually so 
 behind the middle.

 detected by Mr. G. Lewis in Japan, namely, in the 
 islands of Kushiu and Nipon ; and it is remarkable from 
 bearing a certain primd facie resemblance to some of the 
 smaller members of Calandra ; whilst likewise its deeply 
 sculptured, besmeared surface, rather elliptic outline, and 
 costate elytra recall to mind some of the features of the 
 Dryophthorides : nevertheless its 7 -jointed funiculus and 
 pseudotetramerous feet affiliate it at once with the true 
 Cossonids. In other respects it is conspicuous for its 
 rostrum being faintly attenuated towards the tip, for its 
 eyes being exceedingly depressed, for its elytra being 
 lopped-off straightly at their extreme apex, for its legs 
 being rather short and robust, for its tibiaa (which have 
 their hook powerfully developed) being armed with a small 
 though robust spinule at their inner angle, and for its feet 
 being very short and filiform, with their third articulation 
 not at all expanded or bilobed. 
 
 53. EXODEMA (Wollaston, Trans. Ent. Soc. Lond. 
 22. 1873). The unique insect on which this genus was 
 founded is, like Coprodema and Pholidoforus, from the 
 Japanese archipelago, where it was captured by Mr. Gr. 
 Lewis. Its primd facie aspect indeed, and opake, densely 
 sculptured surface (which is sparingly besmeared with a 
 sort of dirty-whitish, scaly, mud-like deposit), are so 
 strongly suggestive of the former that it might well be 
 regarded, at first sight, as a second member of that group ; 
 yet when closely inspected it differs so essentially in the 
 structure of its feet, which are not only much longer but 
 have their third joint (instead of small and simple) con- 
 spicuously widened and bilobed, that I cannot but think 
 that it should be treated as the type of a nearly-allied but 
 distinct genus. As regards its less important details, its 
 antennae are a trifle more elongate, and not quite so 
 medially inserted (being implanted just perceptibly before 
 the middle of its rather thicker rostrum), its eyes are a 
 little more developed, its elytra are not at all truncated at 
 their apex, and its metasternum and legs (especially the 
 latter) are appreciably longer. Its femora also, at any 
 rate the anterior pair, are proportionately not quite so 
 clavate. 
 
 54. MELARHINUS (nov. gen.). The insect from which 
 the characters for the present genus have been drawn out 
 
548 Mr. T. Vernon Wollaston on the 
 
 is a native of Madagascar, and has been communicated by 
 Mr. Pascoe. It is rather larger in size than the other 
 members of the immediate department into which I have 
 admitted it ; nevertheless it agrees with them in its surface 
 being dark, closely sculptured, and opake, and more or less 
 besmeared with dirty, mud-like scales. In other respects 
 it is remarkable for its rostrum being broad and depressed, 
 channeled down the middle, and with the eyes exceedingly 
 prominent ; for its prothorax being appreciably narrower 
 than the elytra, a good deal rounded at the sides, and very 
 deeply constricted behind the apex ; for its elytra (which, 
 when viewed beneath the microscope, are most minutely 
 and very sparingly pubescent) having their somewhat large 
 punctures arranged in longitudinal rows, but scarcely in 
 stride ; and for its antennae and legs being much thickened, 
 the former moreover having their funiculus-joints very 
 closely pressed together, or compact, and their club narrow 
 and not at all abrupt. 
 
 55. PSILOSOMUS (nov. gen.}. The present genus is 
 remarkable amongst the Cossonidce for the dark and opake 
 (yet bald and densely punctured) surface of the somewhat 
 CW#we?r-shaped insect for the reception of which it is 
 proposed, and which has been communicated to me by 
 Mr. Janson as a native of Ceylon, and by Mr. G. Lewis, 
 who captured it at Paulo Penang, in the Malay peninsula. 
 And it is further distinguished by the comparative large- 
 ness of its prothorax, by its widely-sulcated elytra, and by 
 its first abdominal segment (which is more conspicuously 
 separated from the second one than is usual in this family) 
 having in the male sex a deep rounded depression in the 
 centre which is curiously filled up w r ith fulvescent pile. 
 Its rostrum is rather short, broad, and subparallel, though 
 a little longer in the males than in the females, with 
 the antennae inserted at about the middle point ; and its 
 legs (which are robust and a good deal thickened, especially 
 as regards their anterior femora) have their tarsi consider- 
 ably developed, with the ultimate joint elongate, and 
 furnished with powerful claws. 
 
 I have little doubt that the affinities of Psilosomus are 
 with such forms as Coprodema and Exodema, from Japan, 
 in which the elytra are costate, and the body (although 
 very much smaller) is equally opake and densely sculptured. 
 Nevertheless in both of those groups the surface, instead

 of being bald, is more or less besmeared with mud-like 
 scales.*

 species (from Southern Africa) for which the present was 
 established by Fahraeus, I know nothing whatever con- 
 cerning either its structure or its affinities, the former, 
 if we may judge from the diagnosis, being of the most 
 commonplace description, and such as might apply equally 
 to two-thirds of the entire Cossonidce ; whilst so far as the 
 latter are concerned, not a syllable is recorded by Fahraeus 
 except that the group represents a new " tribe " of the 
 family. But why this should be the case it is impossible 
 to conjecture, seeing that his description does not indicate 
 so much as a single structural anomaly. Since he speaks 
 however of the elytra as sulcate (no allusion being made 
 to punctured stride), and the body as black and closely 
 sculptured, I am inclined (on the merest conjecture) to 
 place the genus next to Psilosomus (from Ceylon and the 
 Malayan peninsula), in which the elytra are emphatically 
 " sulcated," and the punctation is altogether dense.] 
 
 57. AMOKPHOCERUS (Schonherr, Cure. Disp. Meth. 
 329. 1826). The South- African genus Amorphocerus, for 
 types of which (the A. rufipes, Boh., and the A. zamice, 
 Boh.) I am indebted to Mr. Pascoe and Mr. Janson, has 
 many peculiarities of its own, one of which, namely the 
 construction of its tibiae, would rather tend to remove it 
 from the present family. These latter are decidedly 
 abnormal for the Cossonida, being not only unusually 
 broad, triangular, and compressed, but with their apical 
 hook (understanding that almost universal appendage as 
 a prolongation of the outer angle) obsolete. It is true that 
 a long and curved spine is conspicuous, but then it does 
 not proceed from the external angle (which is merely sur- 
 mounted with a very short and straight spinule) ; and also 
 
 I think it is far from unlikely that the insect which forms the type of 
 the genus Psilosomus is the one which was described by Mr. Walker (Ann. 
 Nat. Hist. iv. 218, 1869) under the name of " Cossonus? hebes ; but since 
 his diagnosis is contained in ten words, and is unaccompanied by a single 
 remark, it is impossible without an examination of the type itself to decide 
 this point. But in any case the generic characters have not hitherto been 
 defined ; and I have thought it worth while therefore, even if the species 
 should prove eventually to be the one alluded to by Mr. Walker, to place 
 them on record. 
 
550 Mr. T. Vernon Wollaston on the 
 
 that there is a second spine, from the inner angle of the 
 tibia, of almost equal length, besides an additional smaller 
 one between the elongated central one and the outer 
 angle, an anomalous structure (amongst the Cossonids), 
 which causes the whole apex to be essentially spinulose. 
 Yet there is a little indication of an irregularity of (at all 
 events) partially the same character, in the (likewise 
 African) genus Aorus and the South- American Lipan- 
 cylus, which I have consequently placed in juxta-position 
 with Amorphocerus, and in which at any rate the terminal 
 uncus appears (as it seems to me) to be obsolete. 
 
 In other respects Amorphocerus is remarkable for its 
 rather depressed, broadish, parallel-oblong, posteriorly- 
 obtuse body, dark hue, and very deeply (though not very 
 densely) sculptured surface ; for its rostrum being parallel 
 and somewhat robust, though not very long ; for its pro- 
 thorax being largely developed, though not wider (at its 
 broadest part) than the elytra, and but very little con- 
 stricted in front ; and for its antennas, which are implanted 
 considerably behind the middle of the rostrum) being 
 short and thick, with the funiculus (the first joint of 
 which is much enlarged) exceedingly solid and compact, 
 and the club small and not at all abrupt. Its scutellum is 
 very conspicuous, and the third articulation of its feet is 
 considerably expanded and bilobed. 
 
 58. LIPANCYLUS (nov. gen.). I am indebted to 
 Mr. Jan son for the loan of the very extraordinary insect 
 for which the present genus is established, and which is 
 South- American, it having been taken, I presume by 
 Mr. Bates, in the region of the Amazon. I have not the 
 slightest doubt that its true affinities are with Aorus from 
 western Africa, with which it agrees in the most ano- 
 malous character (for the Cossonidce) of its tibial hook 
 being obsolete, as well as in its elongated, extremely 
 slender and cylindrical (though less curved) rostrum, its 
 narrow, parallel body (which, as in that genus, will be 
 seen, when viewed beneath a high magnifying power, to 
 be not altogether bald), in its unconstricted pro thorax, its 
 wide and greatly developed feet (the third joint of which 
 is much expanded and bilobed), its minute claws, and 
 in the fact of its long and thickened legs being more 
 approximated at their base than is usual in the members 
 of this family. Nevertheless, although approaching Aorus 
 in so many important respects, Lipancylus has an abun- 
 
Genera of the Cossonidce. 551 
 
 dance of very remarkable features which, are essentially 
 its own, amongst which the proportions of its abdominal 
 segments are by far the most significant, the first and 
 second of them being less elongated, while the third and 
 fourth are considerably more so, than is customary amongst 
 the Cossonids. The shape of its prothorax, likewise, is 
 very peculiar, it being somewhat elongate-quadrate, and 
 rather wider (if anything) before than behind ; its scutellum 
 is rather large and squarish ; its elytra are bi-arcuated in 
 front, and separately rounded-off at their extreme apex; 
 its antennge are slender; and its tibiae, especially the 
 anterior ones, are armed at their inner angle with a dis- 
 tinct spine. The two last-mentioned characters, however, 
 are almost equally indicated in Aorus. 
 
 59. AORUS (Schonherr, Gen. et Spec. Cure. iii. 253. 
 1836). The genus Aorus was established by Schonherr 
 to contain an insect which is found in western Africa, 
 and for an opportunity of inspecting which I am indebted 
 to Mr. Pascoe. It was placed by Schonherr amongst the 
 Cholides ; and although removed by Lacordaire into the 
 CossonidcB, it is by no means a very typical member (any 
 more than Amorphocerus is) of the latter, for its un- 
 usually approximated coxag, narrow, transverse eyes, and, 
 as it seems to me (for the example before me is a good deal 
 mutilated), obsolete tibial hook, are all points of great 
 significance which would certainly tend to remove it from 
 the Cossonids. Still, its other features being on the Cos- 
 sonideous type, I have admitted it into the family, content 
 to call attention to these particular characters (whatsoever 
 they may be worth) of manifest divergence. In other 
 respects, Aorus is remarkable for its exceedingly long, 
 slender, and very arcuated rostrum (into which the antenna? 
 are implanted a little before the middle), for its transverse 
 eyes being altogether depressed, for the second joint of its 
 funiculus being considerably elongated, for its tibiaa (the 
 four anterior ones of which are armed with a spine at their 
 inner angle) being sparingly asperated, or muricate, in- 
 ternally, for its third tarsal articulation being a good deal 
 expanded and bilobed, and for its claws being unusually 
 minute. In outline it is somewhat long and narrow, with 
 the elytra cylindrical and rather convex, and the pro- 
 thorax (the widest part of which is, if anything, a little 
 wider than the elytra) large, convex, regularly oval, and a 
 good deal (and equally) rounded at the sides. 
 
552 Mr. T. Vernon Wollaston on the 
 
 60. HOMALOXENUS (nov. gen.). I am indebted to John 
 Gray, Esq., for the very curious little insect, from the 
 West Indian island of St. Domingo, to receive which the 
 present genus is proposed ; and it is so perfectly distinct 
 from every other Cossonideous form with which I am 
 acquainted that I had some hesitation at first in admitting 
 it into the present family at all ; nevertheless the unmis- 
 takeable structure of its abdominal segments, in conjunc- 
 tion with its tibial hook and other details, are sufficient I 
 think to indicate its affinities. Its distinctly annulated 
 club however, added to its elongate, slender, straightened, 
 and longitudinally-strigose rostrum, into which the antennas 
 are implanted at the apex, are anything but in accordance 
 with the usual modifications of the Cossonid type, being 
 prima facie somewhat suggestive of certain groups amongst 
 even the Erirhinides, an analogy which (however super- 
 ficial) its uni-dentate femora would not tend to invalidate. 
 But apart from these various peculiarities, Homaloxenus 
 is remarkable for its rather broad and extremely depressed 
 body which is subopake, ferruginous, and sparingly 
 clothed with a very minute decumbent subcinereous pubes- 
 cence ; for its entire prothoracic disk being very curiously 
 flattened, or impressed; for its antennas being long and 
 slender, with the second joint of their funiculus (which is 
 remarkably lax) conspicuously lengthened; and for its 
 tibias (which have their hook very small) being barbed, or 
 pencilled, at their apex with fulvescent hairs. Its scutellum 
 is largely developed, its metasternum is somewhat short, 
 and the third articulation of its feet is much expanded and 
 bilobed. 
 
 61. STENOTIS (Wollaston, Ins. Mad. 316. 1854). 
 The Madeiran genus Stenotis is founded on one of the 
 most remarkable little Cossonids with which I am ac- 
 quainted, its extremely narrow, elongate outline, pallid 
 hue, and subdepressed, delicately sericeous surface, added 
 to the excessive length and slenderness of its rostrum, its 
 elongated prothorax and metasternum, its thickened legs, 
 and its unusually widened and deeply bilobed third tarsal 
 joint, giving it a character essentially its own. Its sub- 
 sericeous surface indeed, and general structure, show it to 
 belong, unmistakeably, to the same department as Mesites ; 
 nevertheless I believe that its nearest known ally is the 
 South- American genus Eucoptus, from Brazil and the 
 region of the Amazon, with which it has a good deal in 
 
Genera of the Cossonida. 553 
 
 common, not only as regards its narrow, parallel, somewhat 
 flattened, and very minutely sericated body, its elongated, 
 slender rostrum, its greatly lengthened prothorax and 
 metasternum (the former of which is very powerfully con- 
 stricted in front), the conspicuously bilobed third joint of 
 its feet, and the minuteness of its claws, but likewise in 
 the smallness of its eyes, and in the curious tendency of 
 its prothorax to be concave beneath. 
 
 In other respects Stenotis is remarkable for its narrow 
 and porrected head, for its intermediate coxae being not in 
 the least degree more remote from each other than the 
 anterior ones, and for its metasternum (which is remark- 
 ably convex) being furnished on either side in front with 
 a minute transverse plait (or perhaps, rather, a cluster of 
 plaits), which have somewhat the appearance of two 
 roughened foveas. Its antennse (which are medial in the 
 males, but post-medial in the females) are rather long 
 and slender, with their second funiculus-joint appreciably 
 lengthened ; its sculpture is less coarse than in most of the 
 immediately-allied groups; and its prothorax, as in the 
 forms around Mesites and Cossonus, is widely channeled 
 behind. Its type (the S. acicula, Woll.) is one of the 
 rarest insects of the Madeiran archipelago, being found 
 amongst the laurels at a high elevation, on the foliage of 
 which it appears to subsist. 
 
 62. EUCOPTUS (nov. gen.). I am indebted to Mr. 
 Pascoe for the loan of a female example, and to Mr. Fry 
 for a male one, of the interesting little insect from which 
 the characters for the present genus have been compiled. 
 They are both of them South- American, the former, 
 judging from a label which is appended to it, having been 
 captured (I -presume by Mr. Bates) in the region of the 
 Amazon, and the latter in Brazil (I believe near Rio 
 Janeiro). In size and outward appearance Eucoptus has 
 very much in common with such forms as Pentarthrum 
 and Stenotrupis ; but its funiculus is composed of seven, 
 instead of only Jive, joints ; and it is clear to me that its 
 affinities, in reality, are with the types which cluster around 
 Mesites, particularly with the remarkable Stenotis acicula 
 of Madeira. I have already called attention to the many 
 characters which it possesses in common with that insect ; 
 and I need here, therefore, only state that Eucoptus is 
 conspicuous for its narrow, parallel, depressed, and piceous 
 body (the elytra however being of a paler, or more rufo- 
 
554 Mr. T. Vernon Wollaston on the 
 
 castaneous, hue), which at first sight appears to be per- 
 fectly bald, but which when viewed beneath a high magni- 
 fying power will be seen to be very minutely and spar- 
 ingly sericeous ; for its rostrum (which is just appreciably 
 widened towards the apex) being elongated and slender in 
 the female sex; for its antennas being implanted into the 
 latter considerably behind the middle ; for its rather por- 
 rected head and depressed eyes; for the sharpness, and 
 fineness, of its sculpture ; for its limbs (particularly the 
 hinder legs) being somewhat short, its club rather narrow, 
 and its third tar sal joint bilobed; for its prothorax and 
 metasternum being a good deal lengthened; and for the 
 first and second segments of its abdomen (the former of 
 which, in the male sex, has, apparently, a large and 
 rounded tubercle in the centre) being separated from each 
 other by a fo'-arcuated line. Its prothorax is free from 
 a longitudinal groove ; and its elytra have their stride 
 nearly simple, and the interstices somewhat transversely- 
 reticulated. 
 
 63. MESITES (Schonherr, Gen. et Spec. Cure. iv. 1043. 
 1838). A very careful examination of the various species 
 from the Madeiran, Canarian, and Cape- Verde archi- 
 pelagos, which I have hitherto referred to Mesites, has 
 convinced me that they connot properly be admitted into 
 that group as represented by its European members, of 
 which the M. pallidipennis is the universally-acknow- 
 ledged type ; and therefore I have no choice but to restrict 
 Mesites to the particular insects (namely the M. pallidi- 
 pennis and cunipes, and the more recently enunciated 
 M. aquitanus) which it was originally intended to embrace, 
 the M. Tardii, of western Europe, belonging manifestly 
 to one of the Atlantic types. 
 
 As thus understood, Mesites may be said to differ from 
 its more immediate allies (comprised in the two following 
 genera) in its body being more parallel, cylindrical, and 
 convex, as well as somewhat more shining; in its pro- 
 thorax being more strictly oblong (instead of subtriangu- 
 lar) ; in its head being more incrassated, and with the 
 eyes wider apart ; in its male rostrum being shorter, and 
 relatively more robust and linear, it being less appre- 
 ciably widened at the insertion of the antennas ; in the 
 latter being much thicker and more abbreviated, particu- 
 larly as regards their scape (which is likewise more out- 
 wardly curved) ; in its funiculus (the second joint of which 
 
Genera of the Cossonidce. 555 
 
 is not lengthened) being especially more incrassate, and 
 its club comparatively small and narrow; in its meta- 
 sternum being a trifle more elongate ; and in its coxae 
 being a little less widely separated. 
 
 64. RHOPALOMESITES (nov. gen.'}. The type of this 
 genus I regard to be the M. Tardii, of western Europe, 
 an insect which ranges likewise to the Azores; and 
 associated with it are several species from the Madeiran 
 and Canarian archipelagos, two of which (namely the 
 maderensis, and the Teneriffan and Gomeran persimilis), 
 although with small distinctive features of their own, may 
 possibly prove to be, in reality, but geographical modifi- 
 cations of the Tardii. The members of this group differ 
 from Mesites proper, chiefly, in their male rostrum being 
 considerably longer and slenderer, and proportionately a 
 little more widened at the point where the antennae are 
 inserted ; in the latter (which are implanted either in or 
 before the middle, in that particular sex, instead of 
 behind it) being very much thinner and more elongate, 
 with the scape especially, and second funiculus-joint, more 
 lengthened, and with the club very much larger and more 
 abrupt; in their head being less incrassated and their 
 eyes more approximate; in their legs being relatively a 
 little longer, and rather more widely separated at the base ; 
 and in the third articulation of their feet being appreciably, 
 though minutely, bilobed. They are also a trifle less 
 cylindrical than the true Mesites (having a more evident 
 tendency to be subfusiform), as also a little less convex, 
 and not quite so shining ; their prothorax is more trian- 
 gular (or less oblong\ and is more conspicuously channelled 
 behind in the males and carinated in the females ; and 
 they are often sparingly clothed with an exceedingly 
 delicate sericeous pubescence. 
 
 65. ODONTOMESITES (nov. gen.). Two of the (so-called) 
 Mesites from the Canarian archipelago, and one from the 
 Cape Verdes, I had long ago detached from the re- 
 mainder, making them to constitute a distinct section of 
 the genus, in which the body is more fusiform and de- 
 pressed, and the male femora are furnished beneath with 
 an obtuse anguliform tooth ; and it is quite clear, there- 
 fore, that if the Tardii and its immediate associates be 
 
 TRANS. ENT. SOC. 1873. PART IV. (OCT.) R R 
 
556 Mr. T. Vernon Wollaston on the 
 
 disunited from Mesites proper (as I cannot but think is 
 absolutely necessary), these three species must likewise 
 form a separate, though closely allied, group. In their 
 smaller size, more fusiform outline, and general structure, 
 they are of course nearer to Rhopalomesites than to Mesites ; 
 nevertheless they have a more decided tendency to posterior- 
 attenuation than even the smaller members of the former, 
 and (in addition to the subdentate femora to which I have 
 just alluded) they possess a very peculiar feature in the 
 fact of their male rostrum being fringed with elongate 
 fulvescent hairs, on either side, from the point at which 
 the antennas are inserted to the apex. Added to which, 
 their rostrum in the opposite sex is less abruptly thickened 
 at its extreme base ; their legs are proportionately a trifle 
 more incrassated, and the intermediate coxae wider apart ; 
 and the third joint of their feet is, as in Mesites proper, 
 quite unexpanded and simple. 
 
 The species of Odontomesites, so far as I have hitherto 
 observed, are attached exclusively to the rotten stems and 
 branches of the various Euphorbias. 
 
 [66. PORTHETES (Schonherr, Gen. et Spec. Cure. iv. 
 1041. 1838). The genus Porthetes was founded to receive 
 a Cossonid (the P. zamia, Bohem.) from southern Africa ; 
 and although I have not been able to procure an example 
 for inspection, the published diagnosis appears to be suffi- 
 cient to render its peculiarities intelligible. It is described 
 as having much the primd facie aspect of Mesites., the 
 type being a little shorter, but a trifle wider, than the 
 European Cossonus ferrugineus, and of a blackish hue, 
 with the elytra ferruginous. As in Mesites and its imme- 
 diate allies, the rostrum (and to a certain extent, even the 
 antennae) vary according to the sex, it being in the males 
 thickened throughout its basal half, with the anterior por- 
 tion narrow and cylindrical (the exact reverse, be it ob- 
 served, of what is the case in the forms around Mesites), 
 but in the females incrassated (as in those groups) at the 
 'extreme base only. Its antennae (which are abbreviated) 
 are shorter in the females than in the males, and are 
 Z>as//y-inserted in the former sex but medially in the 
 latter ; and the scape is more powerfully clavate in the 
 males than in the females. In its third tarsal joint, too, 
 being somewhat expanded and bilobed Porthetes recedes 
 from Mesites and Odontomesites, and is more on the 
 Rhopalomesites pattern.] 
 
Genera of the Cossonida. 557 
 
 67. MEGALOCORYNUS (nov. gen.\ It is for the Cos- 
 sonus depressus and conicirostris, of Boheman, and a 
 closely allied species (or perhaps only local variety) which 
 has been communicated by Mr. Janson, all of them from 
 Mexico, that the present genus is proposed ; and, apart 
 from every other character, they may be immediately dis- 
 tinguished from the Cossoni, not only by their largely- 
 developed club, but by the sexual disparity in the structure 
 of their rostrum and antennae, in both of which respects 
 indeed, no less than in their more evenly and densely punc- 
 tured prothorax, they are far nearer, in reality, to the 
 groups around Mesites than to Cos sonus. 
 
 Not to mention its parallel and extremely flattened body, 
 Megalocorynus is at once remarkable for the enormous 
 size and length of its capitulum which is parallel-oblong, 
 and densely clothed with a velvety pubescence ; and its 
 scape is peculiar from being somewhat twisted and sub- 
 compressed, the inner edge (on account of the abrupt, 
 but elongate, apical clavation) seeming to be almost 
 scooped-out, or at any rate sinuated, posteriorly. Its 
 rostrum, too, in the female sex, is of a very unusual 
 shape, being rather short and narrow, but nevertheless 
 flattened, and gradually a little contracted towards the 
 base ; whilst in the males it is longer, and dilated ante- 
 riorly much after the fashion of the ordinary Cossoni. 
 Its eyes (instead of being transverse) are nearly round ; 
 its prothorax is somewhat small and abbreviated, and a 
 good deal rounded at the sides ; its elytra (which are 
 appreciably wider than the prothorax) are parallel and 
 deeply sculptured, with the interstices almost costate ; and 
 its coxas (even the front ones) are exceedingly remote. Its 
 antennas in the male sex are inserted a long way before, 
 but in the females a long way behind, the middle of the 
 rostrum ; and they are likewise longer and more robust in 
 the former case than in the latter, and have their scape 
 more conspicuously clavate, and their capitulum, if any- 
 thing, even still more developed. 
 
 68. CATOLETHRUS (Schonherr, Gen. et Spec. Cure. iv. 
 1077. 1838). The genus Catolethrus is composed of 
 a few elongated (occasionally minute), narrow, somewhat 
 shining, depressed Cossonus-like insects, of which the 
 main distinguishing features seem to consist, so far at 
 least as I am able to detect them, in their rostrum being 
 (especially in the female sex) rather elongate and slender, 
 
 RR 2 
 
558 Mr. T. Yernon Wollaston on the 
 
 but nevertheless a little, and gradually, widened both 
 towards its base and apex, and divided from the forehead 
 by a very appreciable line ; in their eyes being exceedingly 
 depressed, transverse, and slightly approximated above ; 
 in their prothorax and metasternum being a good deal 
 lengthened ; in their scutellum being very conspicuous ; 
 in their elytra (which are just perceptibly broader than the 
 prothorax) being deeply sulcated towards the apex where 
 they are separately, and minutely, rounded off; in their 
 antennae and legs (the former of which are inserted con- 
 siderably behind the middle of the rostrum, and have the 
 second funiculus-joint exceedingly abbreviated) being rather 
 short and incrassated ; and in their feet being much thick- 
 ened, with the third articulation conspicuously dilated and 
 bilobed. Their four anterior coxae are about equally wide 
 apart, and the hinder ones are but slightly more remote 
 from each other. 
 
 I am indebted to Mr. Fry, and also to Mr. Janson, for 
 the opportunity of inspecting types of the C. longulus, 
 Bohm., from Mexico ; and several other species are now 
 in my possession (all of them South American) from the 
 exceedingly rich collection of Mr. Fry. My own belief 
 is, that the genus, as properly defined, is essentially an 
 American one ; for although it is true that three or four 
 supposed representatives have been described from the 
 islands of the Pacific, and elsewhere, I think it is never- 
 theless far from unlikely that these latter will be found, on 
 a more critical examination, to pertain to some other 
 group, perhaps to Catolethromorphus, or even to the 
 Pentarthrideous genus Stenotrupis. 
 
 69. STENOTRIBUS (nov. gen.~). The type of this genus 
 is a minute and narrow Brazilian Cossonid (communicated 
 by Mr, Fry as having been received from Bahia), which 
 is without doubt very closely allied to Catoletlirus for 
 one of the smaller members of which it might well at first 
 sight be mistaken. An accurate inspection, however, will 
 show that it cannot in reality be associated with the 
 Catolethri, from which it differs in its antennas being 
 inserted into the middle (instead of considerably behind 
 the middle) of its rostrum; in the latter being more 
 parallel and cylindric (there being scarcely any tendency 
 to either an anterior or a posterior thickening), and even 
 still more conspicuously divided from the remarkably 
 convex forehead ; in its prothorax being extremely elon- 
 
Ginera of the Cossonida. 559 
 
 gated, less constricted in front, and perfectly even (there 
 being no traces either of keel or depression) ; in all its 
 coxae being subequallj apart (even the anterior ones being 
 widely separated); and in its feet being much less in- 
 crassated, and with their third joint small and simple. 
 Its elytra too are more decidedly parallel (or less fusiform) 
 than in Catolethrus ; its body is less depressed ; its colour 
 is nearly black ; and its eyes are so extremely sunken as 
 to be with difficulty detected. 
 
 [70. PROECES (Schonherr, Gen. et Spec. Cure. iv. 
 1080. 1838). The present genus is one of six which 
 I have not been able to inspect; but the two species to 
 contain which it was established by Schonherr, and which 
 are apparently peculiar to Madagascar, are stated by 
 Lacordaire to be very similar at first sight to the smaller 
 members of Catolethrus, and quite as narrow. Their 
 rostrum however is said to be slenderer and more cylin- 
 drical; their antennae are shorter and less thickened, 
 with the second funiculus-joint longer, and the club larger 
 and more abrupt ; and their legs are thinner, with the third 
 articulation of the feet simple and not at all wider tha^i 
 those which precede it.] 
 
 71. PHACEGASTER (nov. gen.). Although it does not 
 tally precisely with the diagnosis, I have little doubt that 
 the insect for which the present genus is proposed is the 
 Catolethrus nasalis of Boheman, from Brazil. At any rate 
 several examples are now before me (collected by Mr. Fry 
 near Rio Janeiro, and in the province of S ta Catharina) 
 which I feel satisfied are congeneric, and I believe also 
 conspecific, with the nasalis ; but it is nevertheless quite 
 evident that they cannot be associated with the Catolethri. 
 Not to mention their much larger size, they differ essen-* 
 tially from the latter in the form of their rostrum which 
 is very much broader, somewhat depressed above, and 
 gradually (though not very considerably) widened from its 
 base to its apex ; and the antennas are implanted into it 
 nearer to the middle point, In other respects, Phaeegaster- 
 is remarkable for a great peculiarity in its first and second 
 abdominal segments each of which are furnished with 
 two rounded, ocelli-like spaces, filled up with coarse 
 granules, The two on the basal segment are rather larger 
 and more widely separated from each other than those on 
 the second one, and are placed before the middle ; whereas 
 
560 Mr. T. Vernon Wollaston on the 
 
 those on the latter are not only more approximate, but are 
 situated close behind the anterior margin. And there is 
 also another feature which distinguishes this genus from 
 every other with which I am acquainted, namely the 
 fact that its two hinder femora are fringed beneath, in the 
 middle, with a narrow edging of short fulvescent pile ; 
 whilst the tibiae (of the same pair of legs) are arcuated, 
 and furnished on their inner side, towards the base, with a 
 fascicle of elongated hairs. The legs are thicker than in 
 Catolethrus, and the spine at the internal angle of the 
 tibiae (especially the four posterior ones) is larger and more 
 robust. 
 
 72. GLCEODEMA (nov. gen.). The two beautiful insects, 
 communicated by Mr. Pascoe, on which the present genus 
 is founded (and which were captured by Mr. Wallace at 
 Dorey and Saylee in New Guinea), are so remarkably alike 
 in colour, outline, and sculpture that I cannot feel alto- 
 gether certain that the very peculiar discrepancy which 
 they display in the construction of their rostrum may not 
 be merely sexual ; and if this should prove to be the case, 
 it follows that they must be treated eventually as members 
 of a single species. With but a solitary example however 
 of each of them to judge from, I feel scarcely warranted in 
 assuming that a character so important and conspicuous 
 is indicative only of the sex ; and I have therefore regarded 
 them as specifically distinct. The feature to which I 
 allude is the shape and length of the rostrum, which in 
 one of the individuals now before me (and, I may add, 
 very much the larger one of the two) is gradually widened 
 towards the tip to a most marvellous extent, whilst in the 
 other it is but slightly increased in breadth. 
 
 In other respects Glceodema is remarkable for the large 
 size, fusiform outline, and somewhat convex, highly- 
 polished, almost unsculptured surface of the insects of 
 which it is composed, which moreover are anomalously 
 variegated with red and black (a very unusual combina- 
 tion amongst the Cossonidce). Their head is elongate, 
 and greatly exserted ; their eyes are rounded, rather promi- 
 nent, and wide apart ; their prothorax is convex, and per- 
 fectly even (being quite free both from depressions and 
 keel) ; and their limbs are long, but much incrassated, 
 the second funiculus-joint being remarkably shortened, 
 the club narrow and acuminated, the four hinder tibiae (as 
 in Phacegaster, Exonotus, and others of the immediately- 
 
Genera of the Cossonidce. 561 
 
 allied forms) armed with a powerful and compressed spine 
 at their inner angle, and the feet short and thick, with 
 their third articulation expanded and deeply bilobed. 
 Their prothorax, too, (as in the Madeiran Stenotis} ap- 
 pears to be more or less concave beneath ; and their 
 antennas are implanted either about or a trifle before the 
 middle of the rostrum. 
 
 73. GLCEOXENUS (nov. gen.). It is for an insect from 
 Madagascar (which has been communicated by John 
 Gray, Esq.) that I have proposed the present genus ; and 
 its primd facie aspect and fusiform outline are somewhat 
 those of a gigantic, deep-black, highly-polished, and lightly- 
 sculptured Rhyncolus. When more closely examined how- 
 ever it will be seen to belong, in reality, to a totally dif- 
 ferent group, the robust and peculiarly-shaped spine at 
 the inner angle of its four posterior tibise, in conjunction 
 with its much abbreviated and thickened feet (the terminal 
 joint of which is extremely short and conical) affiliating it, 
 most unmistakeably, with the types around Glceodema, 
 Phacegaster, Exonotus, and Pseudocossonus. Its rostrum 
 is rather broad, depressed, and nearly parallel (though 
 whether this is equally the case in both sexes I have no 
 means of judging) ; its limbs are incrassated and exceed- 
 ingly robust ; the third articulation of its feet, although 
 greatly thickened, is simple ; and the spine at the inner 
 apex of its front tibias is marvellously lengthened and de- 
 veloped, in which latter respect it differs from every other 
 Cossonideous form with which I am acquainted. As in 
 most of these immediate genera, its club is narrow and 
 somewhat acuminated ; but its antennas are inserted a 
 little more evidently before the middle than is usual in the 
 majority of its allies. 
 
 74. EXONOTUS (nov. gen.},, A genus the type of which 
 (captured by Mr. Wallace in the islands of the Malayan 
 archipelago) is well distinguished by its elongate, narrow, 
 and parallel outline, rather large size, and convex, shining 
 surface, which is of a deep black, with the anterior por- 
 tion of the elytra red. Its head and rostrum are broad, 
 and of nearly equal width, the latter (which seems to be 
 linear in the females, but rather expanded anteriorly in 
 the males) being somewhat short; its coxae are all of 
 them about equally separated; its legs are exceedingly 
 thick and robust ; its tibiaa (the front pair of which are 
 
562 Mr. T. Vernon Wollaston on the 
 
 conspicuously biflexuose) have their apical cavities, for 
 the reception of the tarsi, unusually large and open ; and 
 the latter (as in most of these immediately-allied forms) 
 are remarkably short and incrassated, with the third joint 
 deeply bilobed, and the ultimate one abbreviated and 
 conical. The prothorax and elytra are very distinctly 
 margined at their respective bases (the latter of them 
 likewise at the apex) ; and, as in the neighbouring groups, 
 the antennae are thick, with the second funiculus-joint 
 much reduced in length, and the club narrow and acumi- 
 nated. 
 
 75. PSEUDOCOSSONUS (Wollaston, Trans. Ent. Soc. 
 Lond. 27. 1873). The genus Pseudocossonus was 
 founded by myself a short time ago to receive two insects 
 which were captured by Mr. GT. Lewis in Japan ; and a 
 third exponent is now before me, from the collection of 
 Mr. Pascoe, which was obtained by Mr. Wallace at Dorey 
 in New Guinea. There can be no doubt, I think, that 
 its affinities are with such forms as Catolethrus and Phace- 
 g aster, from America ; though still more so with Exonotus, 
 from the Malayan archipelago, and the Indian Catolethro- 
 morphus with which it agrees in its rostrum being more 
 parallel, and not divided from the forehead by a basal line, 
 as well as in the fact of its eyes being rounder, more promi- 
 nent, and more widely separated, in its prothorax being 
 perfectly even (or free alike from keel and depression), in 
 its elytra being entire at their extreme apex, and in its four 
 posterior coxae (instead of the four anterior ones) being 
 equidistant. As in most of the allied groups, the tibiae of 
 Pseudocossonus are furnished at their inner angle with a 
 rather robust spinule ; and the feet are abbreviated and 
 thick, with the third joint bilobed, the terminal one very 
 short and conical, and the claws exceedingly minute. 
 Indeed this shortness of the tarsi is even still more ex- 
 pressed in Pseudocossonus than it is in any of the genera 
 to which I have above alluded, the basal and ultimate 
 articulations being greatly reduced in length. Its body is 
 shining, nearly parallel, and slightly depressed ; and the 
 sculpture anteriorly and underneath is somewhat fine. 
 Although usually dark, its elytra (which do not appear 
 to be margined at their extreme base, or at their apex) 
 are occasionally rufo-castaneous, especially in front, a 
 peculiarity of coloration which is equally indicated in 
 Exonotus. 
 
Genera of the Cossonidce. 563 
 
 76. CATOLETHROMORPHUS (nov. gen.}. The present 
 genus is founded on a single example from the East Indies 
 (I have no note as to the exact region) which has been 
 communicated by Mr. Fry ; and we may perhaps look 
 upon it as the Asiatic representative of the American 
 group Catolethrus, to which in external aspect and struc- 
 ture it is a good deal allied. Yet it manifestly cannot be 
 associated with the Catolethri, the most essential features 
 of which (as regards rostrum, eyes, and antennae) it does 
 not possess. Thus, not only is its rostrum thicker and 
 more strictly parallel (there being no indication of the 
 slight, and gradual, widening towards the base and apex 
 which is so characteristic of that group), and undivided 
 by a frontal line from the head, but the latter is more 
 exserted and largely developed, and has the eyes (instead 
 of transverse, subapproximated, and depressed) rounded, 
 comparatively wide apart, and slightly prominent. Its 
 prothorax also is considerably shorter (being more trun- 
 cated both before and behind), as well as more even and 
 convex, there being no trace of either a keel in front, or 
 of a groove-like depression behind ; its elytra are more 
 strictly parallel, and entire (instead of separately and 
 minutely rounded-off) at their apex ; its antennae (which 
 are inserted in the middle of the rostrum, instead of con- 
 siderably behind it) have their scape very much longer, 
 and their club more abrupt and less acuminated ; and its 
 intermediate coxse are more remote. This last-mentioned 
 peculiarity has a certain importance amongst these imme- 
 diate groups, occasioning the four posterior legs (instead 
 of, as in Catolethrus, the four anterior ones) to be equi- 
 distant at their base. 
 
 77. BRACHYCH^ENUS (nov. gen.\ In its rather narrow, 
 parallel, and depressed body (which is of a palish, rufo- 
 ferruginous hue), as well as in its linear and somewhat 
 robust rostrum, its even prothorax, and the fact of its 
 four posterior legs being subequally distant at their base 
 (occasioned by the intermediate pair being rather wider 
 apart than is usual), the little Cossonid from which the 
 details for the present genus have been compiled, and 
 which has been communicated by Mr. Pascoe as having 
 been taken by Mr. Wallace at Sarawak in Borneo, has a 
 good deal in common with Catolethromorphus ; neverthe- 
 less its type is very much more minute than that of the 
 latter, its rostrum is relatively not so elongated, its 
 
564 Mr. T. Vernon Wollaston on the 
 
 antennas (which are inserted rather behind the middle, 
 instead of at the middle point) have their funiculus much 
 shorter, as well as more robust and compact, with the 
 second joint so greatly abbreviated that it is almost con- 
 cealed from view, and its feet are less elongate, with the 
 third articulation simple (instead of expanded and bilobed ). 
 Its capitulum, too, although not particularly abrupt, is 
 very largely developed; and its eyes, although not pro- 
 minent, are likewise large. 
 
 78. STENOMIMUS (nov. gen.). The present group is 
 founded on a very minute, narrow, and pallid little 
 Brazilian Cossonid, several examples of which were cap- 
 tured by Mr. Fry near Rio Janeiro ; and it may perhaps 
 be looked upon as the more southern representative, in 
 
 South America, of the preceding genus Avhich occurs 
 from, at all events, the West Indian islands to the region 
 of the Amazon. It is indeed very closely allied to Micro- 
 mimus, from which it nevertheless differs in its narrower, 
 and relatively more parallel and elongated, outline ; in its 
 surface being less shining, and (at any rate so far as the 
 elytra are concerned) minutely and sparingly sericeous ; in 
 its rostrum being longer, slenderer, and more strictly 
 parallel; in its antennas being medial as regards their 
 insertion (instead of ante-medial) ; in its eyes being more 
 rounded, and (instead of depressed) extremely prominent ; 
 in its prothorax being more triangular, and more deeply 
 constricted in front ; in the elytra being proportionately 
 rather longer and more linear, but at the same time less 
 acuminated at their extreme apex, where the pygidium is 
 but barely covered; in its tibias being more evidently 
 armed at their inner angle with a minute spinule ; and in 
 its tarsi being slenderer. 
 
 79. MICROMIMUS (nov. gen.). The two minute and 
 rather closely allied species for which the present genus is 
 proposed, are from the collection of Mr. Fry. One of 
 them is West-Indian, having been taken in Trinidad ; and 
 the other was captured, apparently by Mr. Bates, in the 
 region of the Amazon. They are remarkable for their 
 pallid hue, and shining, deeply sculptured, somewhat 
 depressed surfaces ; for their rostrum being short, broad, 
 and nearly parallel (it being but very slightly narrowed 
 posteriorly) ; for their eyes being transverse and ex- 
 tremely large, but nevertheless completely sunken or 
 
Genera of the Cossonidce. 565 
 
 depressed ; for their antennae (which are implanted a little 
 before the middle of the rostrum) having their scape 
 greatly abbreviated, but rather unusually (and suddenly) 
 clavate at its apex ; for all their coxae (even the front ones) 
 being widely, and subequally, separated ; and for the third 
 joint of their feet being simple. Their rostrum is not 
 divided from the forehead by a basal line as in Catole- 
 thrus ; and their body, as in that genus, seems to be 
 perfectly free from pubescence. 
 
 80. GLOGOTROGUS (nov. gen.\ Although prima facie 
 on the Cossonus type, the curious insect which I have 
 made to constitute the type of the present genus, and 
 which has been communicated by Mr. Pascoe and Mr. 
 Janson as having been captured by Mr. Wallace in the 
 islands of Morty and Gilolo of the Malay archipelago, is 
 one of the most anomalous members of the family with 
 which I am acquainted, being conspicuous not only for 
 its highly-polished, almost un sculptured, and extremely 
 flattened body (both above and below) ; but likewise for 
 its greatly exserted, depressed, elongate-squarish head ; its 
 large but sunken eyes, which are a good deal approximated 
 on the under side of the latter ; for its exceedingly short 
 and broad, but nevertheless almost parallel rostrum (which 
 is merely a little contracted at the base) ; for its antennas 
 (which are inserted considerably behind the middle of the 
 latter) having their scape elongate, outwardly curved and 
 compressed, and greatly clavate anteriorly (where however 
 it is obliquely lopped-off on the inner side, occasioning 
 a tolerably well denned angle to be shaped-out at some 
 distance from the tip), their funiculus much abbreviated, 
 but with the joints increasing gradually, but very con- 
 spicuously, in width towards the club which is exceed- 
 ingly large, elongate-oval, and densely clothed (as with 
 velvet) ; for its prothorax being straightly truncated (or 
 even, if anything, perhaps, a little scooped-out), instead of 
 trisinuated, behind, unconstricted in front, and perfectly 
 even; and for its legs (which are short, especially the 
 hinder ones) being very widely separated at their base, 
 with the femora much clavate, and with the tarsi (the 
 third joint of which is simple) rather slender and filiform. 
 
 81. HOMALOTROGUS (nov. gen.). The present genus, 
 together with the one which precedes and the one which 
 follows it, belong clearly to the same geographical type 
 
566 Mr. T. Vernon Wollaston on the 
 
 (or, more strictly, perhaps, to the same cluster of types), 
 peculiar, apparently, to the islands of the Malay archi- 
 pelago ; and yet I scarcely think that they could be 
 regarded as representing even distinct sections of a single 
 group. At any rate, if I were to treat them now as such, 
 I feel that the time would assuredly arrive when (as 
 I have lately done with the forms which cluster around 
 Mesites) they would be separated; and hence I have 
 thought it desirable to forestall that event by detaching 
 them at once. 
 
 With this preliminary remark, I may state that Homalo- 
 trogus differs from Glceotrogus in its type being a little 
 more evidently (though at the same time very lightly) 
 sculptured, and not so highly polished ; in its head being 
 much narrower, more convex, and oval (instead of flattened 
 and subquadrate) ; in its eyes being consequently less 
 widely separated ; in its rostrum being much longer and 
 more convex, and (instead of nearly parallel) with the hinder 
 half comparatively slender and contracted, and with there- 
 fore the anterior one suddenly dilated (much as in Cos- 
 sonus) ; in its prothorax (which is exceedingly even) being, 
 if anything, squarer still, though more evidently constricted 
 at its extreme apex ; in the last three segments of its 
 abdomen being margined behind with a row of large 
 punctures; in its antennae (which are inserted conspi- 
 cuously before, instead of behind, the middle of its much 
 longer rostrum) having their scape straighter and less 
 outwardly curved, and only obsoletely truncate towards the 
 inner apex (and therefore with but a very slight tendency 
 for the anguliform projection which is so marked a feature 
 in Gloeotrogus), and having their second funiculus-joint 
 appreciably less shortened ; and in its legs being longer, 
 with the femora (at any rate the posterior four) somewhat 
 less clavate, and with the tibise less abbreviated. Judging 
 from the labels which are appended to them, the types 
 now before me (which are from the collection of Mr. 
 Pascoe) were taken by Mr. Wallace in the islands of 
 Coram and Batchian, of the Malay archipelago. 
 
 82. ISOTROGUS (nov. gen.). This genus makes a nearer 
 approach to the normal Cossonus pattern than either of 
 the preceding two ; yet it certainly is not identical with 
 that group, its extremely flattened body and unimpressed 
 prothorax, and the peculiar construction of its scape 
 (which is biflexuose, and shows a more distinct tendency 
 
Genera of the Cossonida. 5G7 
 
 than even the last genus does, for the inner anguliform 
 projection which is so conspicuous a feature in Glceotrogus\ 
 added to its abbreviated funiculus, its greatly enlarged 
 capitulum, its elongate, oval, much exserted head, and the 
 fact of its large but depressed eyes being considerably 
 approximated on the underside, affiliating it unmistakeably 
 with the small assemblage of types which appear to be 
 characteristic of the islands of the Malayan archipelago. 
 
 As compared with Homalotrogus, the present genus is 
 remarkable for the body being both larger and very much 
 more deeply and coarsely sculptured ; for its rostrum being 
 more parallel (i. e. much less contracted behind, and there- 
 fore less expanded in front) ; for its head being a little 
 thicker (or less narrowed) ; for its antennae (which are 
 more strictly medial as regards their insertion, instead of 
 ante-medial) having their scape rather more evidently 
 sinuated internally, and their second funiculus-joint not in 
 the slightest degree lengthened ; and for its prothorax 
 being longer, or more oblong, and more decidedly tri- 
 sinuated along its basal edge. The two species from which 
 my generic diagnosis has been compiled were collected by 
 Mr. Wallace in the island of Batchian. 
 
 83. HETEROPHASIS. (nov. gen.\ The very beautiful 
 insect, so remarkable for its rufescent prothorax, and the 
 other, totally dark one, on which the present genus is 
 established, are from the collection of Mr. Pascoe, and 
 were captured by Mr. Wallace at Dorey in New Guinea. 
 In the more ordinary .construction of their rostrum and 
 antennae they make a still nearer approach to Cossonus 
 than the members of any of the three preceding groups. 
 Nevertheless I think they may fairly be separated from 
 the true Cossoni, from which they may be said to differ 
 not only in their surface being at times more elegantly 
 coloured (a fact of great significance in this department of 
 the Rhyncophora), but likewise (which is equally im- 
 portant) in their more fusiform, or less parallel, outline, 
 their extremely depressed surface (in which respect they 
 agree with the three preceding genera), their rather more 
 prominent eyes, and in their prothorax (which is alike 
 free from a keel and a depression) being almost totally 
 unsculptured with the exception of being impressed down 
 either side of its central region (and in the anterior con- 
 striction) with a row of punctures which in H. ruficollis 
 are extremely large, but almost obsolete in the concolor. 
 
568 Mr. T. Yernon Wollaston on the 
 
 The first and second segments, also, of their abdomen are 
 more completely fused into each other than is the case 
 with any of the Cossoni which I have hitherto examined. 
 Although rather more parallel in outline, I believe that 
 the Cossonus glabricollis, Bohm., from southern Africa, 
 will enter into this genus. 
 
 84. COSSONUS (Clairville, Ent. Helv. i. 58. 1798). 
 The genus Cossonus, so widely distributed over the world, 
 presents a great amount of structural instability as regards 
 the degree of rounded-dilatation towards the apex of its 
 rostrum and the coarseness of its sculpture ; and I think it 
 far from unlikely that a close comparison of its numerous 
 representatives (as at present acknowledged) might enable 
 us to separate them into two or three tolerably distinct 
 groups ; nevertheless as it is not my object in this memoir 
 to monograph the closely-allied species of genera which are, 
 on the whole, sufficiently well understood, I shall not 
 attempt to do more than detach a few forms which are 
 readily accessible to me, and concerning the claims of 
 which for separation there can, I think, be no reasonable 
 doubt. Amongst, however, its multitude of specific modi- 
 fications, Cossonus is by no means unsatisfactorily defined, 
 the more or less narrow, parallel, depressed, deeply- 
 sculptured, dark, and shining bodies of the insects of which 
 it is composed, in conjunction with the form of their ros- 
 trum (which is always contracted behind, though often 
 very shortly so, and spatulate, or expanded in front, 
 sometimes to an extraordinary, and at others to merely a 
 slight, extent), its more or less longitudinally-impressed 
 prothorax, rather widely separated anterior coxse, and the 
 unexpanded third joint of its feet, giving it a character 
 which it is impossible to mistake. Its antennas are inserted 
 into the roundly-expanded apical portion of its rostrum ; 
 its eyes are transverse, oval, and not very widely separated 
 across the forehead ; and its surface is nearly always free 
 from every trace of pubescence. 
 
 85. HYPONOTUS (nov. gen.}. I am indebted to Mr. 
 Pascoe for the loan of the curious insect for which the 
 present genus has been erected ; and, judging from a label 
 which is appended to it, it appears to have been captured 
 by Mr. Wallace at Singapore, in the Malay peninsula. 
 Its elongated, parallel outline, and dark, opake, closely 
 sculptured surface, give it somewhat the appearance at 
 
Genera of the Cossonida. 569 
 
 first sight of a minute Tenebrio ; and although it is mani- 
 festly much allied to Cossonus, I feel satisfied that it can- 
 not be admitted amongst the numerous specific modifi- 
 cations of that extensive group. Thus, not only is its 
 opake upper-surface sparingly besprinkled with very short 
 and minute fulvescent setaa (a circumstance of great signi- 
 ficance in this particular department of the present family), 
 but its head is considerably broader and more developed, 
 with the eyes (which are rounder and more prominent) 
 consequently much more remotely separated ; its rostrum 
 likewise is wider, shorter, and more parallel (it being 
 merely a trifle narrowed, and gradually so, behind), its 
 prothorax (which is relatively more abbreviated and more 
 oval) is very coarsely, densely, and uniformly punctured 
 all over, but unimpressed (although sub-carinulated) pos- 
 teriority, and its legs (the intermediate ones of which are 
 extremely wide apart) have their femora (the four hinder 
 ones of which are less clavate), their tibias (which are 
 slightly flexuose), and their tarsi, each of them, propor- 
 tionately, more elongated. 
 
 86. BOROPHLCEUS (nov. gen.}. The members of the 
 present genus, which appear to be North- American (one 
 of them having been communicated by Mr. Fry as coming 
 from Mexico, and the other by Mr. Janson), are, I sus- 
 pect, in most collections treated as small Cossoni ; never- 
 theless it seems to me to be scarcely possible to refer them 
 to Cossonus, as rigidly defined, from which they differ, 
 not only in their rostrum being relatively shorter, broader, 
 and nearly parallel (indeed completely so as regards one 
 of the species), but also in their eyes being larger, rounder, 
 more prominent, and more widely separated, in their pro- 
 thorax being more equally and closely (though very 
 coarsely) punctured, and unimpressed behind, in their 
 metasternum being longer, their coxae more approximate, 
 and the third joint of their feet less decidedly simple (it 
 being, although very minutely so, sub-bilobed). 
 
 87. PACHYTROGUS (nov. gen.}. The affinities of this 
 genus, which is founded on an insect from Chili com- 
 municated by Mr. Janson, are extremely difficult ; for 
 whilst the large size and robust general aspect of its type, 
 in conjunction with its somewhat shortened scape, is at 
 first sight entirely suggestive of Stereoborus and Stereo- 
 tribus. its still thicker and broader rostrum (the tendency 
 
570 Mr. T. Vernon TV r ollaston on the 
 
 of which is rather to be subtriangular, than posteriorly 
 narrowed), and its depressed, less widely separated eyes, 
 added to its very grossly and equally punctured prothorax 
 (which is free from a constriction in front, and is nearly 
 unsinuated at the base), and its convex body, are far more 
 in accordance with what obtains in such sub-Hylastideous 
 groups as Brachytemnus. On the whole, however, I think 
 it will be more natural to retain it in the vicinity of the 
 former, and more especially since their is no appearance 
 of the excessive reduction in the length of the scape which 
 is so characteristic of the latter ; nor yet of the obtusely- 
 desilient apical region of the elytra, the subcontiguous 
 anterior coxas, and the slender feet, of those particular 
 types. Its tibiae are not so abbreviated as in Stereoborus 
 and Stereotribus, and the front pair seem to be simple (or 
 W7z-augmented internally ; its scutellum is largely deve- 
 loped ; and its rostrum, although unprovided with any 
 anomalous tubercles and channel-like fissures, is never- 
 theless obsoletely gibbose, or uneven, on its upper surface. 
 
 88. STEREOBORUS (nov. gen.}. The insects which 
 I would include under the present genus and the follow- 
 ing one, although apparently (for the most part) unde- 
 scribed, are some of them (on account, doubtless, of their 
 rather large size, and dark, shining, deeply-sculptured 
 surfaces) mixed-up in collections with the Cossoni from 
 which, however, they are, nevertheless, totally distinct. 
 Indeed in the construction of their extremely robust and 
 thickened legs they are very peculiar, the femora (though 
 especially the anterior ones) being greatly incrassated, 
 whilst the tibise are unusually short, broad, and somewhat 
 compressed, with the terminal hook powerfully developed ; 
 the front pair moreover being abnormally augmented on 
 their inner edge (at some distance behind the internal 
 angle) by a kind of lamelliform triangular plate (which 
 however only becomes conspicuous when the insect is 
 viewed obliquely). In other respects Stereoborus recedes 
 from Cossonus in its head being considerably larger and 
 broader ; in its eyes (which are rounder and more promi- 
 nent) being consequently much wider apart ; in its rostrum 
 (which is furnished with a narrow, anteriorly-evanescent 
 channel in the centre, arising out of a minute frontal 
 fovea) being conspicuously shorter, broader, and more 
 parallel (in fact nearly quadrate) ; in its prothorax being 
 longer, and somewhat more cylindrical; and in it 
 
Genera of the Cossonida. 571 
 
 (though particularly the front ones) being more approxi- 
 mate. Its antennas (which are implanted before the middle 
 of the rostrum) are rather thick, with their scape slightly 
 abbreviated, and their funiculus (the second joint of which 
 is but very little longer than those which follow it) to- 
 lerably compact, though not so compact as in Stereo- 
 tribus. 
 
 The genus seems to be peculiar (so far as I am aware) 
 to the islands of the Malayan archipelago, the specimens 
 now before me (from the collections of Mr. Fry and 
 Mr. Pascoe) having been captured by Mr. Wallace at 
 Dorey in New Guinea, and in the islands of Gilolo and 
 Matabello. 
 
 89. STEREOTRIBUS (nov. genJ). The members of the 
 present group are very closely allied, in external aspect 
 and general structure, to those of the preceding one, 
 from which they seem mainly to differ in their head being 
 a little less widened, and their rostrum (which in the 
 S. incisus and tuber culifrons, from Ceylon, is rather 
 longer, and distinctly narrowed towards the base) being 
 not only furnished behind with a very deep, short, wide, 
 and somewhat gaping slit, or (as it were) gash (often ac- 
 companied by posterior frontal tubercles and inequalities), 
 which takes the place of the narrow channel in Stereolorus, 
 but likewise more or less bearded beneath, at the apex, 
 with elongated hairs. Their eyes, too, are a little more 
 prominent ; their funiculus (the second joint of which is 
 not at all longer than those which follow it) is more solid, 
 o"r compact ; and the additional lamelliform process which 
 augments the inner edge of the two front tibias is armed at 
 its base with a very conspicuous and robust spine (which 
 is best seen when the insect is viewed obliquely and from 
 behind}. Like that genus, it is widely spread over the 
 islands of the Malayan archipelago, examples, obtained 
 by Mr. Wallace in Batchian and Tondano, having been 
 communicated to me by Mr. Pascoe; and it appears to 
 range eastward, in however a slightly modified form (as 
 witnessed by its somewhat longer and more posteriorly- 
 narrowed rostrum, and its more developed club), to at all 
 events Ceylon from whence several individuals (repre- 
 senting my S. incisus and tuber culifrons) are now before 
 me from the collection of Mr. Fry. 
 
 I have thought it desirable to append a subgeneric title

572 Mr. T. Vernon AVollaston on the 
 
 to the two species from Ceylon, in the event of its being 
 found desirable ultimately to detach them from the others ; 
 though I scarcely imagine that their slight structural 
 peculiarities of rostrum and club are of sufficient import- 
 ance to indicate more than perhaps a geographical modifi- 
 cation of a rather plastic type. 
 
 90. STEREOMIMETES (nov. gen.}. The rather large 
 Cossonid which constitutes the type of the present genus, 
 and which Mr. Pascoe has communicated as coming from 
 Champion Bay in Western Australia, is manifestly akin 
 to Stereoborus and Stereotribus, though at the same time 
 approaching in the outline, colour, and sculpture of its 
 oblong prothorax, as well as in the bipartite structure of 
 the spine which arises from the inner angle of its four 
 posterior tibiae, the genus Phacegaster. However it 
 entirely wants the short conical feet and the peculiarly 
 formed rostrum of the latter, and of the groups which are 
 allied to it ; and its affinities appear to me to be clearly 
 with Stereotribus, with the aberrant members of which, 
 from Ceylon, it very much agrees in (amongst other 
 details) the shape of its robust, posteriorly - narrowed 
 rostrum. 
 
 Despite however the undoubted relationship of this 
 genus to Stereotribus, not only does the form of its almost 
 basally-unsinuated prothorax and elytra and the structure 
 of its inner tibial spur shew it to be unmistakeably distinct ; 
 but its antennae (which are implanted further from the 
 apex of the rostrum) are considerably thicker and differently 
 constituted, their scape being extremely robust, sub-tor- 
 tuous, and powerfully clubbed, their funiculus remarkably 
 broad, but with the joints nevertheless (instead of being 
 compact) sharply and deeply separated from each other, 
 and their capitulum small and narrow (as in the Rhyncoli}. 
 Its rostrum, which is a good deal rounded-outwards ante- 
 riorly, has a wide channel behind (which arises from a 
 large frontal fovea) ; its eyes (as in the neighbouring 
 groups) are very prominent ; its prothorax is much less 
 coarsely punctured, and its elytra are more strictly parallel, 
 than is the case in Stereotribus and Stereoborus ; its legs 
 are longer, and not quite so broad, both of which points 
 are particularly observable as regards the tibia3 ; and the 
 front pair of the latter are less decidedly augmented in- 
 ternally by a lamelliform portion towards their base. Its 
 colour, too, is less intensely black, the anterior segments

 and the underside being (at any rate in the example now 
 before me) piceous, with the limbs of a still clearer tint. 
 
 91. STEREODERUS (nov. gen.}. The present genus is 
 manifestly allied to Stereoborus and Stereotribus, though 
 the rather smaller size to'which its members would appear 
 to descend, added to their more convex, cylindrical bodies, 
 more lightly sculptured surface, and their more conical, 
 unimpressed prothorax, gives them more the appearance 
 at first sight of such forms as Xestoderma and Xestosoma 
 (which are equally dark and highly-polished, and have a 
 broad, abbreviated rostrum) in the vicinity of the Rhyncoli. 
 Nevertheless, the peculiar construction of its rostrum, 
 which is often barbed beneath with long fulve scent hairs, 
 and has three small clefts in the upper anterior excavation 
 which receives the labrum, as well as a curious tendency to 
 be armed with one or more tubercles in the centre behind 
 (all of which exist, more or less modified, in Stereotribus), 
 is too significant to be misunderstood. And when we add 
 to this the characteristic shortness of its scape, the exces- 
 sive robustness of its limbs, and the internally dilated 
 basal half of its anterior tibias (the superadded triangular 
 portion arising from a robust spinule, situated at some 
 distance behind the spiniform inner angle), each of which 
 is conspicuously expressed in that genus, there can be no 
 longer the slightest room for doubt as to its true affinities. 
 Its eyes are large, very wide apart, and somewhat anterior 
 in their position ; and its third tarsal joint, as in most of 
 these immediate groups, is simple. 
 
 Stereoderus is a genus which would seem to have a 
 rather extended geographical range, out of the three 
 species now before me (all of which are from the collection 
 of Mr. Pascoe), two having been captured by Mr. Wallace 
 in the islands of the Malayan archipelago, whilst the other 
 is from the Fiji islands in the Pacific. The latter, how- 
 ever, although I think it is impossible to regard it as 
 generically distinct, shows a slight structural difference in 
 the minute emargination at the extreme apex of its 
 rostrum, the large medially-cleft lobe, which nearly fills 
 up the cavity in the other two species (causing the whole 
 central piece to appear trifid) being so short, small, and 
 entire as to be strictly obsolete. But so diminutive a 
 character, even though structural, can scarcely be regarded 
 as more than a trivial one.

574 Mr. T. Yernon Wollaston on the 
 
 92. OXYDEMA (nov. gen.). The present genus is estab- 
 lished to embrace three large and very closely allied 
 species, two of which (taken by Mr. Wallace in the 
 islands of the Malayan archipelago) are from the collec- 
 tion of Mr. Pascoe, and the other (from Ceylon) in that 
 of Mr. Jan son. They are at once conspicuous for their 
 elongate, narrow, and fusiform outline being a good deal 
 attenuated both before and behind (particularly the latter), 
 their dark hue, and their somewhat slender, considerably 
 lengthened rostrum, which however is not quite parallel, 
 being appreciably broader in its anterior half (in front of 
 the antennae) than it is posteriorly. Their eyes are 
 rounded and prominent, their prothorax is even and much 
 constricted in front, their elytra are gradually narrowed 
 from the base to the apex (where they have a tendency to 
 be separately and minutely rounded-off), their anterior 
 coxaa are very remote, and their antennas and legs (the 
 latter of which have the third tarsal joint bilobed) are 
 rather long. 
 
 93. NOTIOSOMUS (nov. gen.). Three insects now before 
 me two of which have been communicated by Mr. Pascoe 
 as coming from western Australia, whilst the other (bear- 
 ing the label "New Holland") is from the collection of 
 Mr. Fry, although, I think, specifically distinct, belong 
 unquestionably to the same genus, and that genus is 
 certainly not far removed from Oxydema. Nevertheless 
 I feel satisfied that they cannot be actually associated with 
 the members of the latter, which moreover appear to have 
 a more tropical range, occurring in (at any rate) the 
 Malayan archipelago and Ceylon ; and I would therefore 
 regard them as pertaining to an Australian type, which 
 perhaps may have other representatives in its own particu- 
 lar province. 
 
 Primd facie, however, the present genus has much in 
 common with Oxydema, with which it agrees in its 
 rather large size, and in the fact of its rostrum being a 
 little reduced in width behind the insertion of the antennae ; 
 nevertheless it recedes from the exponents of that group 
 in the body being altogether (proportionately) less nar- 
 rowed, and much less attenuated posteriorly, as well as 
 less shining and sometimes less black ; in its rostrum 
 being rather shorter, and not quite so distinctly contracted 
 along its basal half; in its antennas (which are somewhat 
 thinner) having the second funiculus-joint less decidedly 
 
Genera of the Cossonidcs. 575 
 
 abbreviated, and the club less developed ; in its prothorax 
 being generally more conspicuously narrower than the 
 elytra, less elongate, and not so deeply constricted in 
 front ; in its scutellum being less transverse ; in its meta- 
 sternum being appreciably shorter ; and in its feet being 
 slenderer, with their third articulation usually smaller and 
 narrower, and much more minutely bilobed. Its eyes, as 
 in Oxydema, are extremely prominent, and its sculpture is 
 rather coarse. The first of the three species, however, 
 which are described in this paper ( namely the O. major), 
 I may add, is not quite so typical of the group as the other 
 two ; nevertheless I do not think it can be looked upon as 
 an Oxydema. 
 
 94. APHANOCORYNES (nov. gen.) In its rather large 
 size, elongate, narrow, subfusiform outline, and deep-black 
 hue the insect for which the present genus is founded, and 
 which has been communicated by Mr. Pascoe (as having 
 been captured by Dr. Masters at King George's Sound, 
 in southern Australia), has somewhat the appearance at 
 first sight of Oxydema which occurs in Ceylon and the 
 islands of the Malayan archipelago. Nevertheless it 
 differs in its body being more depressed, and much more 
 finely and closely sculptured, in its elytra being less at- 
 tenuated posteriorly, and without any tendency to be sepa- 
 rately rounded-off at their extreme apex, in its rostrum 
 being a litle shorter and entirely parallel, and in its club 
 being very much less developed. Indeed this latter is even 
 smaller, narrower, and more acuminated than in even the 
 typical Rhyncoli. Its prothorax too (which however, as 
 in that genus, is deeply constricted at the apex) is not 
 altogether even, it being widely, but lightly, impressed 
 in the centre behind ; and its third tarsal joint is more 
 evidently dilated and bilobed, and the terminal one is 
 shorter, than is the case in Oxydema. 
 
 95. ORTHOTEMNUS (nov. gen.). As in the two pre- 
 ceding genera, the type of the present group (which ap- 
 pears to be extensively spread over the islands of the 
 Malayan archipelago) is a comparatively large and elon- 
 gate insect, and of a dark hue ; but it recedes in many 
 important particulars from the neighbouring forms, par- 
 ticularly however in its flattened surface, and elongate, 
 triangular prothorax, which is very straightly truncated at 
 the base (where it is of the same width as the elytra 
 
576 Mr. T. Vernon Wollaston on the 
 
 which are perfectly parallel, and are likewise very straightly 
 truncated in front), and in its rostrum being rather long 
 and robust, but of equal breadth throughout, in its eyes 
 being very largely developed, in its elytra being separately 
 recurved at their extreme apex, in its third tarsal joint 
 being small and almost simple, and in its four anterior 
 coxse being very widely and subequally distant, whilst the 
 posterior ones are, if anything, even less remote than the 
 others, a character which is most unusual amongst the 
 Cossonids. The examples now before me (all of which 
 seem to pertain to a single species) are from the collection 
 of Mr. Pascoe, and were captured by Mr. Wallace at 
 Dorey in New Guinea, as well as in Batchian, Makian, 
 and Ceram. 
 
 96. MACRORHYNCOLUS (Wollaston, Trans. Ent. Soc. 
 Lond. 33. 1873). The present genus, which I estab- 
 lished a short time ago to receive a Cossonid which was 
 obtained by Mr. G. Lewis in Japan, and of which a 
 second species (from Ceylon) is now before me, communi- 
 cated by Mr. Fry, is somewhat intermediate between the 
 preceding groups and Rhyncolus ; nevertheless I believe 
 that it is, in reality, far more nearly allied to the former 
 than to the latter. From Rhyncolus it differs, principally, 
 in the body being relatively longer, narrower, and more 
 parallel, it being less convex, and without any tendency 
 to be ovate (or expanded behind the middle) ; and its 
 surface is more shining, and of an intenser black. Its 
 rostrum is more strictly parallel, being indeed, if any- 
 thing, rather contracted,^ perhaps, than otherwise, towards 
 the base (instead of, as in the Rhyncoli, somewhat thick- 
 ened) ; its eyes are larger and more prominent ; its pro- 
 thorax and metasternum are more elongated; its club 
 (although small) is both less narrowed and less acuminate ; 
 and its four anterior coxae are a little more remote. 
 
 97. HETERARTHUS (Wollaston, Trans. Ent. Soc. 
 Lond. 29. 1873). It was for two very closely related 
 species which were captured by Mr. Gr. Lewis in Japan 
 that I lately established the genus Heterarthrus ; and a 
 third is now before me, from the collections of Mr. Pascoe 
 and Mr. Janson, from the same region, it having been 
 taken near Nagasaki, in the island of Kushiu. They 
 may be known from the members of the neighbouring 
 groups by their convex and fusiform bodies having the 
 
Genera of the Cossonidce. 577 
 
 elytra either altogether pale, or else (which would seem 
 to be the normal condition) ornamented with suffused 
 blackish markings. The head is narrow, with the eyes 
 consequently less wide apart than what is the case in most 
 of these immediately-allied types; and the rostrum is 
 somewhat short and robust, though by no means very 
 broad, and gently, but appreciably, dilated towards the 
 tip which is, , itself, rather straightty truncate. The 
 prothorax (which is finely and densely punctulated) is a 
 good deal narrowed, and much constricted, in front ; and 
 the antennae and legs (the former of which have their club 
 shortish, and tolerably abrupt) are comparatively slender. 
 The intermediate coxag are remotely separated (occasion- 
 ing the four hinder ones to be equidistant) ; the femora 
 are unusually thin towards their base ; and the tarsi (which 
 have the terminal joint ordinary and clavate in the males, 
 but subconical in the females) are very conspicuously 
 lengthened. 
 
 98. CONARTHRUS (nov. gen.). In the conical but not 
 abbreviated last joint of its feet (which may, or may not, 
 be indicated in both sexes, for I have only a single ex- 
 ample of each species from which to judge), no less than 
 in the densely punctured anterior portion of its surface, 
 and its short, unacurninated club, the present genus 
 (which is founded on two species whieh were captured by 
 Mr. Wallace in the islands of the Malayan archipelago, 
 and a third, from Cochin China, which has been com- 
 municated by Mr. Fry) is more related, I think, to 
 Heterarthrus and Eutornus than it is to the groups 
 around Exonotus and Phacegaster with the latter of 
 which, nevertheless, in the proportions of its broad head 
 and rostrum, as well as its large size and parallel, cylindric 
 body, it almost entirely agrees. It may be known from 
 the forms amongst which it seems to me most natural to 
 associate it by its elongate, linear outline, black hue, sloping 
 (or sub-perpendicular) scutellum ( a character, however, 
 which is less distinctly indicated in the C. vicinus from 
 Cochin China), its exceedingly flexuose anterior tibise, 
 and its wide head and rostrum, the former of which is 
 also much exserted, whilst the latter varies in the two 
 Malayan examples now before (but which I nevertheless 
 believe are both of them females), being in one instance 
 perfectly parallel, and in the other not only a little longer 
 but appreciably dilated anteriorly. It is possible however 
 that I may be mistaken in regarding these two Malayan 
 
578 Mr. T. Vernon Wollaston on the 
 
 individuals as pertaining to the same sex, in which case 
 the outline of the rostrum may perhaps be only sexual. 
 But, be this as it may, I suspect that they are specifically 
 distinct from each other. 
 
 99. EUTOKNUS (nov. gen.). The two insects which I 
 have described as members of the present genus are from 
 Ceylon and the Malayan archipelago, the one from the 
 former having been communicated by Mr. Janson (to 
 whom I have dedicated the species), whilst the other is 
 from the collection of Mr. Pascoe and was captured by 
 Mr. Wallace.* Indeed, judging from the many examples 
 now before me, the Malayan representative would appear 
 to be widely spread over those particular islands, and also 
 to be remarkably constant, or free from variation, the 
 types of it which I have examined having been obtained 
 in New Guinea, Morty, Tondano, Gilolo, and Makian. 
 
 The characters of the genus are very similar to those 
 of Conarthrus, and yet I feel satisfied that the two groups 
 are essentially distinct, Eutornus receding from the latter 
 not only in the less parallel (or more fusiform) outline, 
 and more lightly sculptured surface, of the insects for which 
 it is established, and in the peculiarity of their colour, 
 which (instead of a uniform black) is rufo-ferruginous, 
 with the anterior and posterior portions more or less suf- 
 fused, or obscured; but likewise in their rostrum being 
 apparently always linear, in their prothorax being less 
 straightly truncated (or more subsinuated) at its base, in 
 their scutellum not being tilted (or sub-perpendicular), in 
 their elytra being (as in Heterarthrus] obscurely, and 
 minutely, rounded-off, separately, at the extreme apex, 
 and in the last joint of their feet being less conspicuously 
 conical. Their first and second abdominal segments, too, 
 are more convex, having scarcely any tendency to be 
 longitudinally hollowed-out, or concave. 
 
 100. COPTUS (nov. gen.\ The two curious and closely- 
 allied little species on which the present genus is estab- 
 lished have been communicated by Mr. Pascoe, and were 
 taken by Mr. Wallace in the islands of New Guinea and 
 Sula, of the Malayan archipelago. Apart from their 
 rather small size, parallel outline, subdepressed surface, and 
 their rufo-piceous, or piceo-ferruginous hue, they may be 
 
 The E. dubius, from New Zealand, is less typical, and may perhaps 
 be fonnd eventually to pertain to a new but cognate genus.

 known readily from the neighbouring forms by their eyes 
 being enormously developed and very prominent, by their 
 antennas (which have the second funiculus-joint much ab- 
 breviated, and the club abrupt) being inserted towards the 
 base of their rostrum, and by the latter being exceedingly 
 broad (indeed scarcely narrower than the head), but never- 
 theless parallel, much arcuated, and straightly truncate, 
 or lopped-off, in front. The third articulation of their 
 feet is simple, and their coxae (even the anterior pair) are 
 widely and subequally separated. 
 
 101. PACHYOPS (nov. gen.}. Two examples of the 
 species for which the present genus has been established 
 (which have been communicated by Mr. Pascoe), were 
 obtained by Mr. Wallace at Sarawak in Borneo. They 
 may be known from the allied forms by their narrow, 
 parallel, cylindric, and rather deeply, closely sculptured 
 bodies ; by their broad, thick, convex, greatly exserted 
 head ; by their short and wide rostrum ; by their long, 
 subconical prothorax, which is but lightly constricted in 
 front ; by their elongate scape, and roundish, abrupt, com- 
 pressed, largely-developed club ; and by their coxas being 
 somewhat less separated than is the case in the neigh- 
 bouring groups, the anterior pair being scarcely, if at all, 
 more remote than in the Rhyncoli. 
 
 102. PENTAMIMUS (nov. gen.). Several examples of 
 a Cossonid which I have received from Mr. Pascoe as 
 coming from King George's Sound in southern Australia, 
 and a closely allied species (likewise Australian) which 
 has been communicated by Mr. Fry, have so much the 
 prima facie aspect of large Rhyncoli that they might be 
 almost supposed to pertain to that genus. Yet their 
 5-jointed funiculus, and rounder and more developed club, 
 show them to be altogether distinct ; though their affinities 
 are so unmistakeably with the Rhyncoliform groups that 
 it would be absurd to suppose (on account of the structure 
 of their funiculus) that they have anything whatever to do 
 with the subfamily Pentarthrides. In other respects Pen- 
 tamimus is remarkable for its shining, deeply sculptured 
 and cylindrical body; for its thickened head, and short, 
 broad (though parallel) rostrum ; for its somewhat incras- 
 sated antennas (which are implanted a little behind the 
 middle of the latter) having their scape a good deal 
 lengthened and backwardly curved ; and for its legs being 
 rather long and thick, with the third tarsal joint simple. 
 
580 Mr. T. Vernon Wollaston on the 
 
 103. TETHACOPTUS (nov. gen.). The present genus, the 
 type of which (although very much smaller, and more 
 lightly punctured) at first sight closely resembles Penta- 
 mimus, is remarkable for its quadriarticulate funiculus,- 
 it being the only instance amongst the entire Cossonida, 
 outside the subfamily Dryophthorides, so far at least as I 
 have hitherto observed, in which that organ is composed 
 of but four joints ; yet so unmistakeably is it a member, 
 as regards the whole of its other details, of the Rhyncoli- 
 form groups that it would be as absurd to remove it on 
 account of the structure of its funiculus into the Dryoph- 
 thorides (with which in everything else it totally disagrees) 
 as it would be to regard Pentamimus and Tomolips as 
 Pentarthrids, or to include Hexarthrum amongst the 
 Onycholipides. In point of fact there can be no question, 
 despite its 4-jointed funiculus, about its affinities ; and it is 
 a significant fact that the only exponents of the subfamily 
 Cossonides in which the funiculus is made-up (so far as I 
 am aware) of less than seven articulations should pertain 
 to genera which appear, in a natural system of arrange- 
 ment, to be at no great distance from each other, namely 
 Hexarthrum (in which the funiculus is composed of six 
 joints), Tomolips and Pentamimus (in which there are 
 but five), and Tetracoptus (where the number is reduced 
 to four). 
 
 Apart however from the primary peculiarity to which I 
 have just called attention, Tetracoptus may be known by 
 its cylindrical body and very lightly sculptured surface ; 
 by its exceedingly short and broad, but nevertheless pa- 
 rallel, rostrum (which has a wide, but shallow, channel in 
 front) ; by its elongate, large, subconical prothorax (which 
 is about the same width posteriorly as the elytra, and is more 
 constricted in front than in Pentamimus):, by the small- 
 ness of its scutellum ; and by its abrupt, considerably- 
 developed club. Its anterior coxse are tolerably wide 
 apart, and the four hinder ones are about equidistant ; its 
 legs (especially as regards the tibiae) are somewhat short, 
 its third tarsal joint is simple, and its claws are minute. 
 
 The single example of this genus from which my diag- 
 nosis is compiled has been communicated by Mr. Pascoe, 
 and was captured by Mr. Wallace at Dorey in New 
 Guinea. 
 
 104. XESTODERMA (nov. gen.). The present genus 
 and the following one are a good deal allied to each other, 
 
Genera of the Cossonidce. 581 
 
 and appear to be extensively spread over the Malayan 
 archipelago whence two species of each, now before 
 me (which have been communicated by Mr. Pascoe), 
 were obtained by Mr. Wallace in the islands of Ceram, 
 Morty, Batchian, and Ternate. They belong to a type 
 quite distinct from any of the preceding ones, their very 
 lightly sculptured, shining, deep-back, cylindrical bodies, 
 in conjunction with their short, broad, and thick rostra 
 (which are but very little narrower than the head), their 
 excurved scape, their abrupt, compressed club, and the 
 fact of their first and second abdominal segments being 
 divided by a very conspicuous line, giving them a cha- 
 racter which it is impossible to mistake. In Xestoderma 
 the rostrum is free from an anterior channel, the capitulum 
 is but moderately developed, the intermediate coxae are 
 very remotely separated, and the third tarsal joint is quite 
 pimple. The scutellum is either small and somewhat 
 rounded, or else smaller still, short and transverse. 
 
 105. XESTOSOMA (nov. gen.). As already implied, the 
 members of this genus have much the appearance of those 
 of the preceding one ; nevertheless the body is relatively 
 a little broader and thicker ; and moreover, whilst one of 
 the species is highly polished, the other is almost opake. 
 The antennas too have their scape longer and somewhat 
 more robust, and their club dark and sericeous, and con- 
 siderably more developed, it being very large and rounded 
 in the X. grandicollis, but oval in the subopacus. The 
 scutellum is very minute, short, and transverse (rather 
 more so perhaps than in even the Xestoderma atrd] ; the 
 intermediate coxae are rather less widely separated; and 
 the third tarsal joint is not quite simple, it being appre- 
 ciably (at any rate in the anterior pair), though very mi- 
 nutely, sub-bilobed, or cordate. 
 
 106. LISSOPSIS {nov. gen.). Unfortunately the only 
 example which is accessible to me in drawing out the 
 characters of the present genus has lost its antennae ; yet 
 its other details are so well defined, and I am so convinced 
 that the insect cannot be referred to any other group enun- 
 ciated in this paper, that I have no hesitation in treating 
 it as a distinct type of the sub-Hylastideous Cossonids with 
 exceedingly abbreviated rostra. It is at once remarkable 
 for its rather wide, short, and parallel-oblong outline (which 
 is somewhat obtuse both before and behind) ; for its ros- 
 
582 Mr. T. Vernon Wollaston on the 
 
 tram, although thus abbreviated, being nevertheless sub- 
 parallel, rather than triangular, as well as slightly concave 
 in the middle, and most curiously polished (and unsculp- 
 tured) at the base ; for its eyes being, as in Sph&rocorynes, 
 extremely prominent ; for its prothorax being large and 
 convex, about equally rounded at the sides, and of the 
 same breadth at its widest part as the elytra; for the 
 latter being shortly-cylindric, very deeply and coarsely 
 sulcate-punctate, and obtusely rounded and minutely 
 asperated posteriorly ; for its tibias (at any rate the front 
 pair) being subflexuose; and for its coxas, even the an- 
 terior ones, being widely separated. The specimen which 
 has furnished the diagnosis is from the collection of Mr. 
 Pascoe, and was captured by Mr. Wallace at Saylee on 
 the north-west coast of New Guinea. 
 
 107. SPILEROCORYNES (Wollaston, Trans. Ent. Soc. 
 Lond. 38. 1873). Sph&rocorynes is one of the many 
 genera the discovery of which is due to the researches of 
 Mr. Gr. Lewis in Japan ; and it is conspicuous for its 
 very short and channelled rostrum being nevertheless (as 
 in Lissopsis) parallel, rather than triangular, and for its 
 antennas (which are thickened and considerably developed) 
 having their scape elongate, their funiculus abbreviated, 
 and their club large, rounded, and abrupt. Its eyes are 
 extremely prominent; its body (which is subcylindrical, 
 and comparatively lightly and delicately, though rather 
 closely, sculptured) is convex, just appreciably sericeous on 
 the elytra, and rather more evidently so beneath ; and its 
 legs are subequally separated at their base, the ante- 
 rior pair being a little more, and the hinder pair a little 
 less, remote than is usual amongst the Cossonids. Its 
 tibiaa (the front ones of which are slightly flexuose) are 
 rather long ; and its tarsi have their first joint considerably 
 lengthened, and the third one, although scarcely widened, 
 very minutely (but evidently) bilobed. 
 
 108. XENOTRUPIS (nov. gen.}. The affinities of this 
 genus are somewhat difficult, its longer and less thickened 
 rostrum, which is gradually narrowed posteriorly, its less 
 incrassated head, and fusiform (instead of parallel) out- 
 line tending to remove it from these immediate groups ; 
 yet at the same time it has so much in common with 
 them in its convex, shining, deep-black, lightly sculptured 
 surface, its abrupt and compressed club, its largely de- 
 
Genera of the Cossonidce. 583 
 
 veloped prothorax and elongate feet, as also in the fact 
 of its first and second abdominal segments being divided 
 from each other by a conspicuous line, that I think it will 
 be more natural to place it in.the present position than else- 
 where. Its coxae are all of them very widely separated, 
 though each successive pair is more remote than the one 
 which precedes it ; its eyes are exceedingly large and 
 prominent; and its prothorax is slightly concave on the 
 underside. The single species on which the genus is 
 established is from the Malayan archipelago, it having 
 been captured by Mr. Wallace in the island of Batchian, 
 as well as at Dorey in New Guinea. 
 
 109. PACHYSTYLUS (nov. genJ). Two examples of the 
 remarkable species for which the present genus is estab- 
 lished have been communicated by Mr. Fry as having been 
 received from Chili ; and their position in a natural system 
 of arrangement is not altogether very apparent, though, 
 on the whole, I believe that it will be best to place them at 
 no great distance from Rliyncolus. Nevertheless I must 
 admit that in the minuteness of their scutellum they stand 
 perfectly alone amongst those immediate groups, and make 
 a far nearer approach to Phlceophagus and Caulotrupis. 
 Still, the scutellum is not quite obsolete; and the other 
 details of their structure (particularly as regards their in- 
 crassated limbs, and their short first tarsal and second 
 funiculus joints) are so much more in accordance with the 
 corresponding ones of the Rhyncoli that I cannot persuade 
 myself to remove the genus into the Phlceophagus neigh- 
 bourhood ; though, at the same time, I am far from think- 
 ing that the situation which I have selected for it is quite 
 satisfactory. Be the position, however, of Pacliy stylus 
 what it may, it is, as a genus, very distinct from every- 
 thing else with which lam acquainted, the smallness of its 
 scutellum and its extremely prominent eyes (which in the 
 male sex are abruptly terminated posteriorly, but gradually 
 sloped-off in front), in conjunction with its somewhat 
 lengthened rostrum (as compared with that of the Rhyn- 
 coli), which is very much broader in the males than in 
 the females, and its elongate, thickened scape (which, on 
 account of its robustness throughout, is but little clavated 
 towards the apex), giving it a character which is essen- 
 tially its own. Although not wider than the elytra, its 
 prothorax (which is almost free from an anterior constric- 
 tion) is very largely developed, and elongate ; and there 
 
584 Mr. T. Vernon Wollaston on the 
 
 is a peculiarity about * its surface, which is subopake 
 throughout the anterior half, whilst the elytra are slightly 
 shining, and just appreciably even subsenescent (calling 
 faintly to mind certain of the Madeiran Caulotrupides). 
 The underside, too, is rather singularly modified according 
 to the sex, the metasternum in the females being a little 
 concave posteriorly, and furnished in the middle with a 
 minute, isolated keel, abruptly terminated in front ; whilst 
 in the opposite sex the keel is absent, but the concavity is 
 larger (extending through the first segment of the abdo- 
 men). 
 
 110. XENOMIMETES (Wqllaston, Trans. Ent. Soc. 
 Lond. 35. 1873). Xenomimetes is a genus which was 
 detected by Mr. Gr. Lewis in Japan, where indeed the 
 only representative of it which I have hitherto seen would 
 appear to be locally abundant, and (unless I am much 
 mistaken) of pine-infesting habits. In this latter respect 
 it consequently resembles Eremotes and Brachytemnus, 
 with the former of which it has several points (though 
 perhaps only superficial ones) in common. It may easily 
 be recognized by its type being elongate, narrow, and 
 parallel, as well as somewhat opake and very densely 
 sculptured, it being also (when viewed beneath a high 
 magnifying power) minutely pubescent, and asperated, 
 towards the hinder apex (where the elytra are separately, 
 and conspicuously, rounded-off, causing them to appeal- 
 almost divaricate). The rostrum is rather peculiar in its 
 construction, being very short, but nevertheless quite 
 parallel, and suddenly much narrower than the head ; the 
 eyes are extremely prominent ; the club (unlike that of 
 Eremotes and of the Rhyncoli) is rounded and abrupt, the 
 antennae being comparatively slender ; the legs (particularly 
 as regards the tarsi) are a good deal elongated ; the tibiaa 
 (more especially however the anterior pair) are elongated 
 and subflexuose ; and the coxae are but slightly separated, 
 the front ones indeed being not more so than in Rhyncolus, 
 whilst the two hinder pairs (which are about equidistant) 
 are by no means very remote.

 * When compiling my ' Coleopt. Atlantidum,' in 1865, I changed the

 regarded as an offshoot of Rhyncolus, was established by 
 myself in 1861 to receive the " Hylastes crassicornis" of 
 Brulle, a Hylastes-shaped Cossonid which infests the 
 pine-trees of the Canarian archipelago ; and a recent exami- 
 nation of some of the discordant species of (so-called) Rhyn- 
 colus has convinced me that the European R. strangulatus is 
 an undoubted member of the same group. Indeed a single 
 example is now before me (described in the after-part of 
 this paper) which is unquestionably a third representative 
 of Eremotes, but I have unfortunately no information con- 
 cerning its precise habitat. However I believe it to be 
 European , it having been purchased by John Gray, Esq. 
 (in whose collection it now is), some years a^o, from M. 
 Tarnier of Dijon, as the tf R. chloropus" with which, I 
 need hardly add, it has scarcely anything in common. 
 
 Judging therefore from the three members which have 
 hitherto been brought to light, Eremotes may be said to 
 differ from Rhyncolus in its species being not only larger, 
 more cylindrical, and more coarsely sculptured, but like- 
 wise in their prothorax being longer, more cylindrical, 
 and more constricted in front, in its rostrum being shorter, 
 broader and thicker, in its eyes being more prominent, 
 and (above all) in the structure of its antennae, which 
 are extremely incrassated, their funiculus especially being 
 thick and robust, and with the second joint so reduced in 
 length as to be almost hidden within the apex of the greatly 
 enlarged basal one. In all probability Eremotes wih 1 be 
 found to be exclusively of pine-infesting habits ; and it is 
 far from impossible that the species which I have enun- 
 ciated in the latter portion of this memoir, under the name 
 of E. gravidicornis, may prove to have come from the 
 region of the Pyrenees. 
 
 112. KHYNCOLUS (Germar, Ins. Spec. Nov. 307. 1824). 
 Like Phlceophagus and Cossonus, the genus Rhyncolus 
 has had many forms assigned to it, by various authors, 
 which will be seen, when carefully examined, to be not 
 strictly on the pattern of its acknowledged type namely, 
 the European R. ater, Linn, (or chloropus, Fab.). Thus, 
 after removing Eremotes (for the reception of the R. stran- 
 gulatus, Perns), Stereocori/nes (for the truncorum, Germ.), 
 
 of possible confusion. Since however the Munich Catalogue, and others, 
 have not accepted this alteration on my part, which would appear to be 
 deemed by them to have been unnecessary, I have thought it better to 
 revert to the original nomenclature. 
 
586 Mr. T. Vernon Wollaston on the 
 
 Hexartlirum (for the culinaris, Germ., and the submuri- 
 catuSy Bohm. ), and Brachytemnus (for the porcatus, Mull. ), 
 there still remains a residuum, even amongst its smaller 
 members, which future monographers will in all pro- 
 bability further divide ; yet, having reduced its hetero- 
 geneous material thus far, and since I am not professedly 
 in this paper examining every described species (some of 
 which would not be readily accessible), I am content to 
 leave the group partially pruned, and to treat it as repre- 
 sented by those particular exponents which I have been 
 able to inspect, and a list of which will be found in my 
 general summary at the close of the present memoir. As 
 thus curtailed, therefore, I believe that Rhyncolus will be 
 found to possess by no means so universal a range as the 
 different Catalogues would lead us to conclude, none of 
 its members being, apparently, of a large stature. At the 
 same time, however, I would not wish to imply that its 
 area of distribution is unnecessarily restricted ; but merely 
 to call attention to the fact that a vast proportion of the 
 species which figure as Rhyncoli in various papers and 
 local enumerations have in reality nothing in common 
 with the universally-acknowledged generic type. 
 
 For the characters which separate this genus from 
 Phlceophagus, with which it has occasionally been con- 
 founded, the observations which I have given under the 
 latter will suffice. 
 
 113. CAULOPHILTJS (Wollaston, Ins. Mad. 315. 1854). 
 The insect on which this genus was established in 1854, 
 and which I captured twenty-six years ago in the island 
 of Madeira, is still unique ; and in its general appearance 
 it somewhat resembles at first sight a small state of the 
 European Rhyncolus cylindrirostris, Oliv. (= lignarius, 
 Mshm.). Nevertheless when closely inspected it will be seen 
 to be structurally dissimilar in many respects ; and I doubt 
 indeed if it can be actually associated with the Rhyncoli at 
 all. Thus, in addition to its rostrum being obsoletely 
 divided from the head by a very obscure frontal line, or 
 depression, its antennae are by no means on the true 
 Rhyncolus pattern, their club being considerably larger 
 and thicker, but nevertheless more acute at the apex, 
 their funiculus less incrassated (the basal joint being very 
 conspicuously smaller, and the terminal ones narrower 
 and more transverse), and their scape more clavate. Its 
 eyes also are very much more developed, as well as 
 
Genera of the Cossonida. 587 
 
 more approximate (or less widely separated) ; its scutellum 
 is a trifle larger ; and its elytra are somewhat more cylin- 
 dric or parallel. As in the majority of the Rhyncoli, its 
 third tarsal articulation is simple. 
 
 114. XENOCNEMA (nov. gen.). It is for an insect from 
 New Zealand, which has been communicated by Dr. Sharp, 
 and which was captured by Mr. Lawson in Auckland, 
 that I am compelled to establish this genus ; and there is 
 perhaps no member of the Cossonidce which I have hitherto 
 examined which is so difficult as regards its affinities, for 
 although (as I cannot but think) an undoubted member 
 of the present family, in the construction of its tibiae it is 
 nevertheless completely Hylastideous. Moreover the first 
 and second segments of its abdomen are less elongate, and 
 far more divided, than is the case even in those genera 
 which shew an unmistakeable affinity with the Hylastida, 
 the latter of them being (somewhat after the fashion, how- 
 ever, that we observe in Calyciforus) in a different plane 
 from the former; and yet in other particulars as, for 
 instance, in the increased length and diminished breadth 
 of its rostrum, its posteriorly-unasperated elytra, and its 
 unapproximated anterior coxse Xenocnema is absolutely 
 more on the normal Cossonideous pattern than such groups 
 as Stenoscelis 9 Dendroctonomorphus, and Tomolips, in 
 which the body is obtusely cylindrical, and more or less 
 roughened behind, the rostrum exceedingly short and 
 broad, and the anterior legs practically contiguous. Alto- 
 gether therefore I am inclined to place it nearer than those 
 forms to the Rhyncoli and typical Cossonides, whilst at 
 the same time acknowledging its evident relationship with 
 the Hylastids in the very significant structure of its tibiae. 
 These latter indeed are quite unprecedented in any of the 
 Cossonids which have hitherto come beneath my notice, 
 they not only having their tibial hook obsolete (an eccen- 
 tricity which we perceive in a few exceptional genera, such 
 as Thaumastophasis , Aorus, and Lipancylus), but (which 
 is far more important) being expanded towards their outer 
 apex (more particularly however as regards the four hinder 
 ones) into a lamelliform spinose process ; whilst the inner 
 angle is armed with a small spur, which (after the manner 
 so common amongst the Scolytidiens) is developed in the 
 front pair into a comparatively lengthened sub-horizontal 
 spine.

588 Mr. T. Yernon Wollaston on the 
 
 Apart from these eccentricities of tibias and abdomen, 
 Xenocnema is remarkable for its rather short and thick, 
 but somewhat parallel and depressed, body, which is 
 densely and sharply sculptured, and of a piceo-ferruginous 
 hue ; for its rostrum (which is robust, but not particularly 
 abbreviated) being divided by a distinct line (above and 
 below) from the forehead ; for its antennas being almost 
 medial as regards their insertion ; for its eyes being pro- 
 minent ; for its prothorax being large, elongate, and sub- 
 quadrangular ; and for the very unusual sculpture of its 
 elytra, the interstices of which are costiform, each costa 
 however being as it were divided into two by a densely 
 punctulated central stria. 
 
 115. STEREOCORYNES (nov. gen.\ It is the European 
 Rhyncolus truncorum, Germ., which has afforded the 
 details for the present genus ; and it is surprising to me 
 how that remarkably-constructed insect could ever have 
 been associated with the E. ater, and the various other 
 species on the true Rhyncolus-ij^Q. Thus, not only is it 
 more strictly cylindrical and obtusely rounded behind, but 
 its rostrum and antennas are on a totally different pattern, 
 the former being short and subparallel in the males, but 
 still shorter and subtriangular in the females ; whilst the 
 latter (which are inserted considerably behind the middle) 
 are, as compared with those of the Rhyncoli, exceedingly 
 abbreviated and glabrous, the scape particularly being 
 reduced in length, the funiculus-joints closely compacted 
 together, and the club solid, compressed, and ob-triangular 
 (being straightly truncated at its apex). In other respects 
 Stereocorynes is conspicuous for its eyes being extremely 
 sunken or depressed (instead of prominent as in Rhyn- 
 colus] ; for its prothorax being very convex, and quite 
 unconstricted in front; for its femora, particularly the 
 front pair, being considerably thickened, and with a faint 
 appearance beneath of an obtuse anguliform tooth; and 
 for its four anterior coxas being (as in Hexarthrum) so 
 manifestly more approximated as to be well nigh con- 
 tiguous. 
 
 116. HEXARTHRUM (Wollaston, Ann. Nat. Hist. v. 448. 
 1860). The genus Hexarthrum was established by myself 
 thirteen years ago for the reception of a Rhyncolus-\^Q 
 insect, with a 6-jointed funiculus and subasperated elytra, 
 which had been captured in various houses, and outhouses, 
 
Genera of the Cossonidce. 589 
 
 at Madeira, and the habits of which seem to be very 
 similar to those of Pentarthrum and Amaurorrhinus ; and 
 it is only now that I have been enabled to identify it, 
 through the examination of more extensive material, with 
 the European Rhyncolus culinaris, of Germar, a species 
 which does not appear to be common in collections, or 
 one which is very extensively known. Nevertheless I can 
 detect no difference between the Madeiran insect and 
 a type of the latter which has been communicated by 
 Mr. Gray; and I do not hesitate therefore in regarding 
 them as identical. Yet the generic characters of Hexar- 
 thrum remain clear and well defined, and afford another 
 instance of the loose manner in which so many discordant 
 forms have been associated with the Rhyncoli, and of the 
 little care which appears to have been bestowed by certain 
 Coleopterists on the structural features of their published 
 species. 
 
 So far as I am aware, Hexarthrum is the only member 
 of the Cossonida (outside the very anomalous subfamily 
 Onycholipides) in which the funiculusis composed of only 
 six articulations ; and it is further remarkable for its 
 rostrum being short and narrowly subtriangular, for its 
 antennas bring greatly abbreviated (even more so perhaps 
 than in Stereocorynes), for its elytra being shortly cylindric, 
 obtusely rounded behind, and subasperated (particularly 
 as regards their posterior half), and for its four anterior 
 coxse being subcontiguous. As in Stereocorynes and 
 Tomolips, its antennas are not only much reduced in length 
 (especially the scape), but are likewise glabrous, and with 
 the funiculus-joints very closely compacted together; 
 nevertheless the club is more rounded, or less apically- 
 truncate, than in those genera. Its prothorax also (which 
 is unconstricted in front) is nearly unmargined at the 
 base ; its first and second abdominal segments are divided 
 by an unusually distinct line; and its entire surface, 
 although appearing quite bald, will be seen, when viewed 
 beneath the microscope, to be very sparingly besprinkled 
 (which is not the case in Stereocorynes and Tomolips) with 
 a short and most minute pubescence. 
 
 I may state that a Hexarthrum has been detected 
 lately by Mr. G. Lewis in Japan, closely allied to (but 
 nevertheless unquestionably differing from) the European 
 and Madeiran H. culinare ; and also that the European 
 Rhyncolus submuricatus, Bohm., appears, if I may trust 
 an example now before me from the collection of John 
 
 T T 2 
 
590 Mr. T. Vernon Wollaston on tne 
 
 Gray, Esq., and which almost completely satisfies the 
 published diagnosis of that insect, to be likewise a Hex- 
 arthrum. 
 
 117. TOMOLIPS (nov. gen.). With the exception of 
 Pentamimus from Australia, the present genus offers the 
 only exception (as far as I have hitherto observed), outside 
 the subfamily Pentarthrides, in which the funiculus is 
 composed of but five joints ; nevertheless it is so manifestly 
 related to Hexarthrum (in which that organ is 6 -articulate), 
 and likewise to the sub-Hylastideous groups around Bra- 
 chytemnus, that it is as impossible to consider it a Pen- 
 tarthrid as it would be to place Hexarthrum (on account 
 of the number of its funiculus joints) amongst the anoma- 
 lous types of the Onycholipides. And hence, so long as 
 a natural arrangement (and not a purely artificial one) is 
 to be aimed at, I have practically no choice left me but to 
 treat it as an exception in the subfamily Cossonides. It 
 is a significant fact however that its nearest known ally 
 should be a genus in which the funiculus-articulations are 
 likewise reduced in number, in that instance however 
 (from the normal seven) to six ; and it would look therefore 
 as if these immediate forms were subject par excellence (in 
 that particular respect) to instability. Be this however as 
 it may, I will merely repeat that the two genera in question 
 (namely Hexarthrum and Tomolips) are, with the excep- 
 tion of Pentamimus and Tatracoptus, the only instances, 
 so far as I am aware, in the present subfamily, in which 
 the funiculus is otherwise than 7 -jointed, it being com- 
 posed of six articulations in the one, and of five in the 
 other. 
 
 But, apart from this primary peculiarity in the structure 
 of its funiculus, Tomolips is somewhat osculant between 
 Hexarthrum and the strictly sub-Hylastideous genera in 
 which the rostrum is extremely short and broad, the eyes 
 are less widely separated, and the sculpture is remarkably 
 coarse ; whilst in the obtriangular shape of its solid and 
 compressed club it shews an equal affinity with the 
 European Stereocorynes. However its posteriorly-aspe- 
 rated elytra is a character of considerable importance, and 
 one which is likewise indicated (though to a less extent) in 
 Hexarthrum. In its glabrous antennae (the scape of 
 which is much abbreviated, and the funiculus very com- 
 pact), as well as in its four anterior coxae being nearly 
 contiguous, it is in perfect accordance with these imme- 
 
Genera of the Cossonida. 591 
 
 diate forms ; but in its elytra being more produced (or less 
 obtusely-rounded) behind, in its shoulders being rather 
 suddenly and acutely porrected, and in the front tibiae of 
 its type being armed at their inner angle with a compressed 
 bifid spur, there is a singularity about it which is essen- 
 tially its own. The two species of Tomolips which are 
 now before me were taken in Mexico, and are from the 
 collection of Mr. Fry. 
 
 118. DENDROCTONOMORPHUS (nov. gen.'). It is for a 
 Hylastes-, or Dendroctonus-like Cossonid from Ceylon, 
 which (together with an allied species from Malabar, 
 and a rather less typical one from Mexico) has been com- 
 municated by Mr. Fry, that I have been compelled to 
 establish the present genus. In its structural peculiarities 
 it is somewhat intermediate between Brachytemnus and 
 Stenoscelis, agreeing with the former in its conspicuous 
 (though less largely developed) scutellum, comparatively 
 elongate, almost unconstricted prothorax, the general 
 character of its sculpture (which however is not quite so 
 coarse), and in its perfectly simple third tarsal joint; but 
 with the latter in its asperated elytra, greatly lengthened 
 feet, more widely separated eyes, and less glabrous an- 
 tennse. In its thickened head, short, triangular rostrum, 
 sunken eyes, and cylindrical body, it is in accordance with 
 the whole of these sub-Hylastideous forms. 
 
 119. BRACHYTEMNUS (nov. gen.). It is in order to 
 receive the European Rhyncolus porcatus, Miill., and my 
 nearly-allied R.pinipotens from the Canarian archipelago,* 
 that I have proposed the present genus ; and it seems mar- 
 vellous to me now how those curious insects could ever 
 have been included amongst the Rhyncoli from which 
 they appear to differ in nearly every detail of their 
 
 * My B. pinipotens ( = crassirostris, olim), which I captured in an old 
 fir-tree in the island of Grand Canary, is most closely allied to the B. por- 
 catus, Miill., of Southern Europe. Its rostrum and prothorax however (the 
 former of which is free from an anterior channel, whilst the latter is less 
 sinuated on either side behind the middle) are just appreciably less coarsely 
 and more sparingly punctured ; its elytra (which have the shoulders less 
 porrect) are a trifle more parallel, there being apparently no tendency to 
 be even obsoletely widened posteriorly, and have their apical region less 
 obtusely- desilient (or suddenly bent-down wards) ; and the club of its an- 
 tennae is rather more truncated in front. The underside also is somewhat 
 less grossly punctured, and the first abdominal segment, which is convexer, 
 is likewise a little more remotely so. 
 
592 Mr. T. Vernon Wollaston on the 
 
 structure. Indeed in its thickened head, abbreviated, 
 subtriangular rostrum, and depressed eyes, no less than in 
 its greatly shortened antennas and its long and slender feet, 
 the genus has very much the sub-Hylastideous aspect of 
 Stenoscelis : and it may be defined therefore to differ 
 essentially from Rhyncolus in its much shorter and more 
 triangular rostrum ; in its larger and more sunken eyes, 
 which are appreciably less lateral (or more sub-approxi- 
 mated above) ; in its prothorax being altogether more 
 cylindrical and developed ; in its very much more abbre- 
 viated antennas (the scape of which is so reduced in length 
 as to be even shorter than that of Stenoscelis, indeed as 
 short as in the European genera Stereocorynes and Hexar- 
 thrum, or as in Calyciforus and Eurycorynes from Brazil), 
 the club of which, although compressed, is exceedingly 
 rounded, solid, and abrupt ; in its first and second abdo- 
 minal segments being much more conspicuously divided 
 from each other; in its legs and tarsi being slenderer 
 (with the tibial hook more straightened, and the basal 
 joint of the latter rather more elongate) ; and in its coxas 
 being more approximated, the four hinder ones, in fact, 
 being nearly contiguous. In its scutellum however being 
 conspicuous, Brachytemnus recedes from Stenoscelis, and 
 agrees better with the other immediately-allied forms. 
 
 120. CALYCIFORUS (nov.gen.). The very extraordinary 
 insects, which have been communicated by Mr. Fry and 
 Mr. Janson, for which the present genus is established, 
 and which were captured in the provinces of Rio Janeiro 
 and Bahia in Brazil, are amongst the most remarkable 
 members of the Cossonidce with which I am acquainted ; 
 and yet their affinities are, unquestionably, with such forms 
 as the European Brachytemnus, Eurycorynes from Brazil, 
 and Stenoscelis from S e . Helena, Southern Africa, and 
 Japan. Indeed in its thickened head, short, subtriangular 
 rostrum, and sunken, subapproximated eyes, as well as in 
 its excessively abbreviated antennas, its slender, filiform 
 feet, and the fact of its four anterior coxas being nearly 
 contiguous, the genus has much marvellously in common 
 with the first of those groups ; nevertheless the compara- 
 tively large size of its members, and the deep and anoma- 
 lous triangular excavation in the middle of their prothorax 
 behind (immediately in front of the greatly developed 
 scutellum), added to the extraordinary sculpture of their 
 elytra (the sulci of which are wide, deep, opake, and 
 
Genera of the Cossonida. 593 
 
 transversely strigose, whilst the interstices are broad, 
 costate, and shining, and studded with a single series of 
 large subasperated punctures), and their short, transverse, 
 abrupt, anteriorly-truncated, cup- (or somewhat calyx-) 
 shaped capitulum, are all of them characters which are 
 essentially their own. In its prothorax being comparatively 
 unconstricted in front Calyciforus is, likewise, on the 
 Brachytemnus-iy$Q ; nevertheless it is impressed ante- 
 riorly in the centre (which is not the case in that genus) ; 
 and both the prothorax and elytra are coarsely margined 
 at their respective bases. Its four anterior tibiae are armed 
 at their inner angle with a robust spine ; and the hooks 
 of all of them are powerfully developed. Its feet are as 
 slender as, and if anything even more elongated than, in 
 Stenoscelis ; but their third joint is still narrower and more 
 entire, being perfectly simple. 
 
 121. EURYCORYNES (nov. gen.~). I am indebted to 
 Mr. Janson and Mr. Fry for the remarkable Cossonid 
 from which the details for the present genus have been 
 drawn-out ; and it has given me much pleasure in dedi- 
 cating the species to the former of these eminent Cole- 
 opterists. Like Calyciforus it is South- American, having 
 been received by Mr. Janson from the province of Minas 
 Geraes in Brazil ; while Mr. Fry's example appears to 
 have been taken by himself near Rio Janeiro ; and it is at 
 once conspicuous for the very unusual structure of its 
 greatly abbreviated antennas, the scape of which has the 
 joints gradually more and more transverse and lamelliform, 
 the last one of them being so thin as to be only just appre- 
 ciable against the enormously enlarged club. This latter 
 is most peculiar, being exceedingly wide, transverse, and 
 abrupt (more so indeed than in any member of the family 
 with which I am acquainted). In its thickened head, and 
 in the shortness of its triangular rostrum and antennas, as 
 well as in its sunken eyes and elongated slender feet, Eury- 
 corynes has much in common with Brachytemnus, Caly- 
 ciforus, and Stenoscelis ; but it agrees best with the last 
 of those three genera in the fact of its scutellum being 
 nearly obsolete, and in its elytra being asperated (though 
 less so, and in a different manner) both before and behind. 
 Nevertheless, in reality, it is perhaps nearer to Calyci- 
 forus, with which it agrees in its eyes being less widely 
 separated on the forehead, in its prothorax being less short- 
 ened, in its elytra being broadly sulcated (though not quite 
 
594 Mr. T. Vernon Wollaston on the 
 
 so coarsely so as in that group), with their costate inter- 
 stices branded with a row of conspicuous subasperated 
 punctures, in its four anterior coxae (although very closely 
 approximated) not being quite contiguous, and in the third 
 articulation of its feet not being in the slightest degree 
 widened, and remarkably simple. The punctation of its 
 head and prothorax is extremely dense and substrigulose ; 
 and the latter has a polished line, or faint keel, evanescent 
 before and behind, down the centre. 
 
 122. STENOSCELIS (Wollaston, Journ. of Ent. i. 141. 
 1861). Of all the Cossonids which have hitherto been 
 described, perhaps Stenoscelis makes the nearest approach 
 to the sub-Curculionideous forms of the Hylastidce, its 
 shortly cylindric body, which is a little asperated (as well 
 as just appreciably widened, and obtusely rounded) poste- 
 riorly, having much in common with such genera as 
 Dendroctonus. In its thickened head, short, triangular 
 rostrum, and sunken eyes, as well as in its exceedingly 
 abbreviated antennae and its elongated slender feet, it is 
 . on much the same pattern as the three preceding groups ; 
 nevertheless its prothorax is shorter, or more transverse, 
 more constricted anteriorly, and subsinuate on either side 
 in the middle, its four anterior coxae are more completely 
 approximated, and the third joint of its feet (although 
 scarcely at all widened) is not quite simple, being evi- 
 dently, though minutely, bilobed. In the fact of its 
 scutellum being nearly obsolete it has a greater affinity 
 with Eurycorynes than with Calciforus or Brachytemnus ; 
 but its capitulum (which is oval, and on the ordinary type) 
 is not in any degree anomalously developed, and agrees 
 better therefore with the last of those three genera. The 
 three exponents of it which have been hitherto detected 
 are from the island of St. Helena, the Cape of Good 
 Hope, and the Japanese archipelago.
