the base, with a small tuft of hairs external to this crest, with 

 three tufts of hairs posteriorly placed near the inner border of the 

 postero-lateral fuscous patch. The apices somewhat attenuated, 

 and each ending at the suture in a short blunt spine. The pros- 

 ternal process slightly arched, and sending out a small angular 

 process against the coxa on each side just at the commencement of 

 the posterior declivity. The mesosternal process flat, and sending 

 out a similar process on each side a little before its posterior 

 extremity.

This has a strong general resemblance and a somewhat 

 similar style of marking to the preceding. It differs, 

 however, by the more clavate scape of the antennae, the 

 stronger median tubercle on the disk of the prothorax, 

 the base of the elytra strongly punctured and less 

 distinctly asperate, the apices somewhat obliquely trun- 

 cate and without a spine at the suture. The sternal 

 processes are somewhat similar in structure, and the 

 anterior tarsi are slightly dilated and fringed. The eyes 

 in this species are smaller than in the last, and are 

 relatively of about the same size as in I. tridens, Pasc.
