Easily distinguishable among its nearer allies by its 

 strongly convex, almost subgibbous, pronotum (very much 

 more convex than that of H. jubatus). The trilobed outline 

 of tHe head is feebly developed and not divided, the 

 middle lobe about two-thirds of a lateral lobe in size.

This species is very close to H. parvulus, Macl. The 

 punctures of its elytra are very distinctly and more strongly im- 

 pressed, and its prothorax is less strongly rotundate-dilatate 

 laterally behind the middle. It is, however, best distinguished 

 by its longitudinally carinate pygidium. In both species 

 there are differences in the pygidium which I believe to be 

 sexual. In parvulus one sex (I believe it to be the male) has 

 the pygidium very faintly and sparsely punctured, with an 

 almost obsolete tubercle in the middle of its surface; while
