 recta, elytris pygidioque haud coriaceis, tibiis anticis sat

 The erect pilosity is long on the head and along the front 

 margin of the pronotum, scarcely marked on the general surface 

 of the pronotum, somewhat short (but very well marked) on the 

 elytra and pygidium ; the prothorax is rather elongate as com- 

 pared with that of most Onthophagi.

 This species is probably near O. ocelliger, Har., but differs 

 from the description of that species, inter alia, by its upper 

 surface devoid of setae (I have examined numerous specimens) 

 and the interstices of its elytra uniformly convex. The sexual 

 characters of the head are very variable, the frontal carina of 

 the male being in some examples very feeble and scarcely 

 elevated at its ends and one male having the clypeal suture 

 evidently carinate.
