The distinctive characters of this species seem to be, head 

 narrow, the clypeus dilating(butonly very gently) forward from the 

 eyes for a greater distance than the distance from the front to the 

 base of the ocular cavity (in most species of Hopatmm the sides 

 of the clypeus are strongly dilated from the eye), base of pro- 

 thorax not narrower than' the base of the elytra, anterior tibiM 

 only gently dilated (very much less strongly than in the Europ- 

 ean //. sahulosum, L.).

 It appears to me very doubtful whether I am justified in not 

 proposing a new generic name for this insect which differs fi-onv 

 Ilopatrum in its comparatively longantennie, and in the structure 

 of its prothorax. Its antenna? and prothorax are, in fact, those 

 of a Cestrinus. The head differs from the head of both Ilopatrum, 

 and Cestrinus by the sides of the clypeus being dilated laterally 

 only a little beyond the outline of the eyes. The elytral 

 epipleurfB and tarsi are those of a Ilopatrum. I do not think 

 the species can be referred to any of the genera that have been 

 described near Ilopatrum. The anterior emargination of the 

 clypeus is very deep.
