I have included 0. hiarmatus^ Lee., amono- the Central- 

 American species on the strength of a single specimen from 

 Durango left unnamed by Bates. It is apparently a female, 

 and 1 am unable to distinguish it from that sex of the North- 

 American species. 



The two Mexican specimens referred by Bates to 0. hiridus, 

 Westw., agree exactly with the type, and are not, as he 

 suggested, the other sex. He evidently did not recognize 

 the two tubercles described by West wood in the interrupted 

 carina upon the vertex of the head. On tlie other hand, the 

 Guatemalan specimen also placed here by Bates belongs to 

 quite a different species, which, for the sake of clearness, I 

 describe.

Ilufo-brunncus, ovatiis, sat nitidus, parce fulvo-setosus, capite 

 grosse granulato, vertice fortiter transverse carinato, clypeo parvo,

The single specimen is probably a female. The shining, 

 sparsely punctured prothorax distinguishes it from most other 

 species of the genus. The posterior angles of the elytra are 

 distinctly dentate, the mentum is small, rather square, smooth, 

 and very feebly impressed along the middle, the vertex bears 

 a short but sharply elevated transverse carina, and the small 

 clypeus b» ars a rudimentary tubercle (which is, perhaps, more 

 developed in the male) at the middle of the fr^nt margin.
