carina is similar, but instead of a laminate process toothed at middle, 

 there is a slightly curved frontal carina somewhat higher than the 

 clypeal one, and at times almost laminiform ; prothorax nearly plane 

 on the upper side, but nearly vertical at apex, where it is deeply 

 bi-emarginate, and has a bifid tubercle in the middle and one on 

 each side of the emargination, these tubercles are sometimes as 

 conspicuous in the female as in the male, the surface is covered 

 with moderately deep, small punctures set somewhat closely, and 

 there is a median longitudinal groove broadening towards the base 

 and not reaching the apex ; elytra a little rounded laterally at the 

 shoulders, and slightly ampliate at middle, as long as the prothorax, 

 plane above and having a supra-marginal carina overhanging the 

 margin and reaching from base to apex, the suture and third 

 and fifth intervals on each side are raised, narrowly striate, 

 covered with minute granules, and glabrous except at the base, 

 which is slightly pubescent ; no prosternal process ; mesosternum 

 hardly distinct ; metasternum impressed at apex, and with a median 

 longitudinal impressed line ; pygidium finely granulose ; episterna and 

 edge of abdominal segments not projecting beyond the wing-covers. 

 Length 8-10 mm. ; width 1-4^ mm. 



In some examples only the median part of the intervals of the 

 elytra is greenish or bronze, the remainder of the background 

 being testaceous.

 the whole of Natal and of the Transvaal; Lower Ehodesia (Bulu-

 region of Central Africa and it reaches the Galla country and 

 Abyssinia. 



The shape of this species is very different from that of the other 

 South African OniticcUus, and closely resembles that of Oiitlio-

Mentum deeply emarginate at apex, hollowed at base, and either
