154 REVISION OF THE GENUS HETEMONYX, 



defined, the middle lobe appearing not much more than half as 

 wide as, and scarcely longer than, the lateral ones. Entire 

 surface of head nearly even, with scarcely a trace of a clypeal 

 suture. Prothorax just twice as wide as long, its base rather 

 more than half again as wide as its front, which is moderately 

 emarginate and gently bisinuate, with sharp but not very strongly 

 produced angles ; its sides are gently arched, and diverge from 

 the front to near the base, thence becoming nearly parallel ; hind 

 angles (viewed from above) appearing defined, but hardly pointed, 

 or directed hindward ; base only feebly bisinuate and not strongly 

 lobed in middle. Elytra with only sutural stria (and that not in 

 all lights) distinct, their transverse wrinkling not conspicuous, 

 their lateral fringes normal, their apical membrane obscure, their 

 puncturation a trifle finer and closer than the same in H. graci- 

 lipes (the puncturation of the prothorax also being much as in 

 that species). The hind femora are only moderately wider than 

 the intermediate, their inner apical angle moderately prominent 

 but not sharp. The hind coxee, metasternum, and ventral seg- 

 ments do not seem to diff'er noticeably from the same in H. 

 punctipennis and raucinasus, the teeth on the anterior tibise 

 resembling those of the latter.
