of a frontal carina ; from the latter it is also differentiated by the 

 presence of a frontal carina, and the granules of the prothorax are 

 less closely set.

Black, not very metallic, with the elytra pale testaceous and with 

 a very broad basal median fuscous patch varying greatly in size, or 

 entirely black ; antennae yellow ; head covered with rough punctures 

 along the clypeus and scabrose on the vertex, genai rounded, bulging 

 a little, clypeus rounded laterally, deeply and broadly incised at tip 

 and with the angles of the incision produced into a sharp recurved 

 tooth ; prothorax very convex, covered with small tubercles set 

 moderately close to each other and bearing a squamiform flavescent 

 seta, in the large development of the m.ale there is a median shallow 

 impression in the anterior part which is absent in the intermediate 

 and minor development, as well as in the female, it is marginate all 

 round and the base is rounded ; elytra oblongo-ovate, narrowly and 

 not deeply geminato-striate, with the striae closely punctate, intervals 

 convex, and filled at the base with numerous closely set punctures 

 bearing a squamiform seta, but which in the posterior part are 

 arranged in two series ; pygidium vaguely punctulate ; median part 

 of presternum with a broad, smooth space with a basal, short, im- 

 pressed longitudinal line ; inner part of anterior tibiae very distinctly 

 spinose in the male but not in the female which, but for this cha- 

 racter, is entirely like the male ; apical spur moderately slender, 

 curving outwardly in the male, and nearly straight in the female. 



Length 6-8|- mm. ; width 4-5^ mm. 



Hab. Natal (Durban, Malvern, Maritzburg), Damaraland (Salem,

This species, which was first described from examples collected in 

 the island of Zanzibar, occurs also in Massailand and Somaliland. 

 It is evidently very closely allied to, if not synonymous with, 0. 

 bituberculatus and 0. discoideus, Oliv., and was considered to be 

 identical with the former by Boheman. All the examples from 

 Natal which I have seen are entirely black.
