 long, greatly dilated, straight to beyond the middle and rather

This species is similar in size and sculpture to H. subkevis, Fairm., 

 but relatively shorter, with the prothorax less narrowed in front, 

 the hind angles more broadly rounded and the elytral sculpture 

 feebler. The shape of the inner claw of the front tarsus is quite 

 different in the male.

Black, extremely smooth, and rather short and broad. The 

 head is rugose, with an inconspicuous carina before the eyes, 

 broadly interrupted in the middle. The clypeus is produced into 

 two rather sharp reflexed teeth. The iwothorax is closely punc- 

 tured along the extreme posterior margin, but is otherwise smooth ; 

 it is slightly narrowed in front and regularly rounded at the sides, 

 with the front angles acute and the hind 

 angles obtuse. The scuteUum is small 

 and vaguely punctured at the base. The 

 elytra are short, widening a little behind 

 the middle, with faint traces of strite 

 quite devoid of punctures ; there are 

 a very few punctures at the shoulders 

 and tiie outer margins are very minutely 

 punctulated behind. The 2}ro2}ygidium 

 is finely punctured and the stridu- 

 lating files narrow and not reaching 

 the hind margin. The pygidium is 

 densely rugose at the base and almost 

 smooth on the apical half. The front 

 tibia has three strong acute teeth and
