small tubercle which occurs in both sexes between the anterior 

 edge of the eyes or slightly behind it ; other allied species have in 

 truth a median tubercle, but in the <y only, and situated slightly in 

 front of the horns, whereas in 0. fritschi $ it is far removed 

 from the apex of the lamina, and from the base of the horns ; 

 in the ? the absence of the carina on the vertex of the head is 

 also remarkable.

" Little shiny, black, briefly flavous pubescent on the upper side. 

 In the $ the head is but little densely granulate, the clypeus and 

 genae strongly but sparingly rugose-punctate, the punctures inter- 

 mixed with smaller ones, clypeus deeply excised, frontal part 

 arcuately carinate, vertex provided with a somewhat long, little 

 raised, strongly arcuate carina situated far beyond the hind edge 

 of the eyes ; prothorax sparingly granulate, arcuate in the centre of 

 the median part in the £ , sides hardly sinuate behind, base 

 marginate ; elytra broadly striate, intervals plane and with two 

 series of granules ; pygidium but little densely granulate.

Eesembles the ? of 0. fritschi, but differs by the frontal part of 

 the head without tubercle, the vertex with a moderately long 

 strongly arcuate carina situated very far back beyond the hind 

 edge of the eyes, the median projection of the prothorax, which is 

 a little wider, and the more closely set granules in the intervals of 

 the elytra."

Little shiny, black, sometimes with the head and prothorax bronze- 

 green, or with the apex of elytra rufescent, briefly flavous pubescent 

 on the upper side ; head asperate punctate, clypeus deeply excised ; 

 in the $ the frontal part is not carinate, and the vertex is pro- 

 duced into a long, broad, reclining lamina arcuately emarginate at 

 apex, and corniculate on each side and minutely tuberculate at middle 

 before the apex ; in the 2 the frontal part is arcuately carinate, the 

 vertex with a strongly arcuate carina and dentate on each side a 

 little past the eyes ; prothorax sparingly granulate, abruptly de- 

 clivous and almost smooth in the centre in the $ , briefly and 

 arcuately carinate in the $ , sides very slightly sinuate behind, and 

 indistinctly so near the anterior angles, base marginate ; elytra
