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
