from above appear fairly defined and obtuse ; the base is feebly 

 bisinuate, widely and feebly lobed in the middle. Elytra (of the 

 example before me) without trace of striation, their transverse 

 wrinkling coarse and fairly conspicuous ; lateral fringe normal, 

 apex with well defined membranous border. The puncturation is 

 much coarser and stronger than in N. granulifer, and on the 

 whole upper surface much resembles that of //. fulvohirtus 

 (Sect. I.) Hind coxje scarcely so long as the metasternum which 

 is strongly punctured, — closely at the sides, sparingly in the 

 middle, — the former being closely and strongly punctured through- 

 out, and also finely coriaceous. The ventral segments are finely 

 coriaceous, with tuberculous puncturation, which is strong and 

 rather sparing at the sides, — nearly obsolete in the middle. The 

 ventral series consist of moderately stout hairs and are fairly con- 

 spicuous. The hind femora are much wider than the intermediate 

 and have their inner apical angle fairly prominent, but much 

 rounded off". The anterior tibiae are much like those of II. 

 granulifer.

Olypeus almost truncate in front where there is no distinct 

 reflexed margin ; " trilobed outline" of head having the middle 

 lobe quite as wide as the lateral ones and about equal to them in 

 length, but (owing to forward protrusion of labrum) projecting 

 forward beyond them; clypeal suture nearly straight, ill-defined; 

 clypeus forming an almost evenly continuous surface with the rest 

 of the head. Prothoiax about half again as wide as long down
