clypeal suture well impressed, and angulated in the middle. 

 Pro thorax nearly twice as wide as long, its base more than half 

 again as wide as its front, which is moderately emarginate and 

 very slightly bisinuate with moderate angles, the sides gently 

 arched, the hind angles (viewed from a certain point above) rec- 

 tangular, the base evidently bisinuate and rather narrowly and 

 decidedly lobed hindward in the middle. The elytra are quite 

 like those of H. Angustce, the legs and underside also not 

 appearing to differ noticeably from those of the same insect save 

 that the uppermost external tooth of the anterior tibiae is scarcely 

 so strong. 



This species bears a good deal of resemblance to H. inger 

 (though it is much smaller), but differs by the nitid surface of its 

 labrum ; also its puncturation is throughout decidedly coarser. 

 From other allied species it differs inter alia as follows : — from 

 crassus by the very much closer puncturation of its upper sur- 

 face; from Augitstce by the very much closer and coarser punctura- 

 tion of its prothoiax ; from anceps by the rectangular (as viewed 

 from a certain point) hind angles of its prothorax (those of ance2:>s 

 appearing from any point of view almost entirely rounded off), and 

 different sculpture of the ventral segments ; and from all the four 

 just mentioned by the less width of the part of the labrum over- 

 topping the clypeus, the middle lobe of the " trilobed outline" 

 thus appearing narrower.
