front, the anterior carina is arcuate, the posterior inversely arcuate 

 and produced on each side as far as the anterior one ; prothorax 

 simple in front, strongly and densely punctate, the punctures nearly 

 simple in the posterior half, but asperous in front and towards the 

 sides the posterior part of which is slightly sinuate, base marginate ; 

 elytra moderately finely striate, intervals plane, moderately densely 

 granulate ; pygidium moderately densely punctate.

" Little convex, little shiny, black, head and prothorax sub-bronze- 

 black, briefly flavous pubescent, the pubescence, however, longer on 

 the head and on the declivity of the prothorax ; head smooth and 

 having only a few sparse punctures, clypeus and gense rugose, the 

 former hardly sinuate, frontal part arcuately carinate, vertex having 

 between the eyes in the $ a short, erect lamina truncate at apex, 

 and in the 2 a somewhat long, straight carina ; prothorax entirely 

 but not closely asperate punctate, briefly and strongly carinate in the 

 middle, the said carina oftener excised in the centre ; sides hardly 

 sinuate behind, base marginate ; elytra broadly striate, intervals 

 plane, sparingly granulate ; pygidium moderately strongly punctate.

 Eesembles much 0. hycena, Fabric. = 0. impinctus, Fahr., differs 

 mainly by the whole punctuation of the prothorax being finely 

 asperous, instead of being simple; the frontal carina of the $ is less 

 developed in the centre, and moreover in none of the males seen is 

 the median projection of the prothorax as much developed as in the 

 $ of 0. hyana"

"Moderately shiny, cyaneous black, flavous pubescent on the 

 upper side. Head strongly punctate, rugose in front and on the 

 gense ; clypeus rounded, frontal part not carinate in the male, 

 arcuately carinate in the female, vertex with a transverse tubercle in 

 the $ situated between the eyes and at about the middle, and in the 

 $ with a short carina straight but slightly arcuate inversely ; 

 prothorax moderately strongly and not very densely punctate but 

 more densely so on the sides, the punctures are asperous but simple
