The sides of the prothorax are less arched than in most 

 of the allied species, and the point where they begin to be 

 roundly convergent is nearer to the front margin, making 

 the segment appear less transverse than it really is. The 

 front of the clypeus is much more strongly reflexed than in 

 H. tarsalu, Blackb. (which the species resembles in respect 

 of its small head and tarsal structure), the clypeal suture is 

 very much more strongly arched, the pronotum is notably 

 more finely punctulate, the punctures of the elytra are 

 smaller, deeper, and closer, and the hinder process of the 

 hind claws is nearer to the apical process.
