The unique type of this extraordinary insect was cap- 

 tured by Mr. Bryant in Trinidad, in February 1903. It 

 is, of course, a <$, and to Pic's description may be added : 

 anterior tibiae much thickened ; anterior and intermediate 

 femora, and intermediate tibiae, slender, the latter straight ; 

 posterior femora rather stout, clavate. A subcylindrical, 

 pallid insect, with the head, and a small patch on each side 

 of the elytra at about the middle, black ; the head strongly 

 deflexed; the eyes extremely large and contiguous in 

 front ; the antennae (fig. 30a) long, with joints 5-10 

 strongly dentate within and 11 crescentiform ; the pro- 

 thorax not much narrower than the elytra. H. dentati- 

 cornis should perhaps form the type of a separate genus. 

 The general structure is suggestive of that of Blumeno- 

 philus, Pic (1911), type B. exiernenotatus, from Brazil, the 

 smaller eyes and normal antennae of the latter being 

 suggestive of $.

(J. Elongate, rather narrow, dull, the elytra moderately shining, 

 clothed with long, pallid, adpressed hairs ; head, prothorax, and 

 under surface, the antennae with joints 1, 2 and 11, and the tips of 

 the rami, the anterior and intermediate femora at the apex, the 

 posterior femora entirely, and the posterior tibiae in part, black 

 or piceous, the rest of the antennae and legs testaceous or flavous ; 

 the elytra testaceous, with a common, transverse patch on the disc 

 below the base, another before the apex, and a laterally-extended, 

 complete median fascia, nigro-piceous; head densely, finely, the 

 prothorax rugosely, and the elytra very coarsely, subcon fluently, 

 punctate. Head very large; eyes enormously developed, contigu- 

 ous, deeply emarginate, occupying the whole of the sides of the 

 head; antennae long, joints 4-10 each with a long ramus, 11 long, 

 angularly dilated beyond the middle. Prothorax about as long as 

 broad, narrow. Elytra not wider than the head (with the eyes),
