Extremely similar to H. ceneus, Lew., but differs in being 

 black and rather less convex. Also there is a fine punctuation 

 only within tiie stria at the anterior angle, not a band of 

 conspicuous points ; the outer humeral stria is median and 

 very short, scarcely more than an elongate puncture^ and the 

 pygidia are not quite so densely punctate.

This species is larger than M. coronatus, Lew., but extremely 

 like it. It differs by its more oval form, by the transverse 

 frontal stria being broken in the middle, by the thorax being- 

 more distinctly punctate, by the elytral strise being deeper 

 and distinctly crenate, and the interstice between the first and 

 second strise is markedly wider at the base ; the prosternal 

 stria are interrupted like those of coronatus^ and this may 

 ])rove to be a generic character of many species. In coro- 

 natus the elytral striae are less deep and very feebly crenate ; 

 in both species there is a transverse crenate stria marking the 

 suture of the mesosternum, and laterally it is continued along 

 the metasternum. 



It is satisfactory to find a second species which possesses 

 the characters on which the genus was lately established; to 

 these characters may now be added the form of the frontal 

 strise and the similarly interrupted prosternal strise.
