 directis, basi fortiter bisinuata, margine basali sat 

 sequaliter elevato; elytris concinne grosse punctulatis 

 (trans elytron puncturis circiter 17) ; pygidio leviter 

 sparsim minus fortiter punctulato; coxis posticis quam 

 metasternum sat brevioribus, quam segmentum ventrale 

 2"'" paullo longioribus; tibiis anticis extus fortiter 

 tridentatis ; tarsorum posticorum articulo basali quam 2^^

A very coarsely and sparsely punctured species, in this 

 respect resembling //. rras-sus, Blackb. (Group VI.), but hav- 

 ing elytral sculpture still coarser. Its claws resemble those 

 of the preceding species fH. Titigiosus). If the claws were 

 regarded as appendiculate its coarse, sparse puncturation 

 would readily distinguish this species from those near which 

 it would fall in Group II.

This species, with the preceding two, and fulvohirtuSy 

 Blackb., and ruhescens, Blanch., form a small aggregate of 

 species evidently allied naturally inter se, but with very good 

 distinctive characters, as indicated in the tabulation. Of 

 the 5, this species and H. Utigiosus, Blackb., are the two
