and the upper edge of the excavated part is slightly emargiuate 

 in the middle. 



9 . The clypens is rounded, scarcely produced, with a 

 short, straight, and strongly raised sutural carina, and a small, 

 vertical, and truncated posterior horn. There is a rudimentary 

 excavation at the front of the prothorax and a pair of slight 

 tubercles at its posterior edge. 



This species is very closely related to 0. ruhricoUis, Hope, 

 but differs from it by its uniform black colour, the feebler 

 sculpture of the elytra, and the presence of the two cly[)eal 

 tubercles in the male. The basal joint of the antenna has a 

 serrate carina, as in 0. rubricoUis, diaholicus^ and other allied 

 species.

Head, leg?, and underside shining coppery, with prothorax, 

 elytra, and pygidium very opaque, pitchy black, and very 

 minutely setose. Tlie head is impunctate except in front, 

 and the front margin is very feebly reflexed and slightly 

 excised in the middle. The prothorax has a barely perceptible 

 angulation at tiie middle of the base, the hind angles are 

 completely rounded off and the sides feebly sinuated, tlie 

 front angles being prominent but not siiarp. The anterior 

 part is shining and slightly retuse in both sexes. The elytra 

 are faintly striated. 



(^ . There is a short, sharp, curved horn arising from the 

 posterior edge of the head and forming a quadrate lamina 

 at the base. Only the front margin of the clypeus is 

 punctured. 



? . The horn of the male is represented by a strongly 

 raised truncate carina. There is a curved sutural carina, in 

 front of which the clypeus is rugosely punctured. 



This species is very close to 0. concolor^ JSharp, but differs
