diagonal laterally, truncate at tip, and with the two anterior angles 

 sharp and slightly recurved, genye projecting very much, in the 

 centre of the head the male has a curved thick ])ut short horn, 

 obtuse at tip, not longer than two-thirds of the length of the 

 head, and the vertex is carinate, in the female the vertex is also 

 carinate, but instead of a horn there is a frontal carina slightly 

 curved and of the same length as the one on the vertex ; prothorax 

 convex and gibbose in the anterior part in the male, but nearly plane 

 on th(> upper surface, not gibbose in the anterior part in the female, 

 covered with moderately close, not very deep punctures, and having 

 no trace of median longitudinal impression, except a very small one 

 on the base ; scutellum long, sharp ; elytra not longer than the 

 prothorax and attenuate laterally from base to apex, the suture 

 is raised, the intervals plane except the fifth, which is slightly 

 tectiform and ends in a small callus; the episterna of the meta- 

 sternum and the edges of the abdominal segments bulge more 

 than in the two allied species, 0. pallipes and 0. triangulatus ; the 

 pygidium is slightly carinate longitudinally at middle for half the 

 length ; process of the prosternum similar to that of 0. triangulatus, 

 mesosternum sub-carinate lengthways at middle, but not aculeate at 

 tip, metasternum sparsely punctulate and with a longitudinal 

 impressed, median line. 



Length 7-9 mm. ; width 4-5 mm.

Bronze green on the head and prothorax, the latter with a broad 

 lateral flavous band, and a much narrower one along the base ; elytra 

 more or less dark bronze green with a basal transverse series of 

 quadrate flavous patch, a median diagonal one and another along the 

 apical margin ; under side and legs bronze variegated with yellow ; 

 head finely and closely punctulate, clypeus rounded, broadly but not 

 deeply emarginate at apex, gense not projecting beyond the line of 

 the clypeus, the male has a median, clypeal arcuate carina, and 

 between this carina and the vertex a laminate transverse process 

 supporting a short and sharp erect tooth, in the female the clypeal
