club fuscous; clypeus semicircular, neither emarginate nor obtuse 

 in front, margin slightly reflexed ; head very deeply pitted, almost 

 scrobiculate on the clypeus, it has a very faint trace of a frontal 

 carina, and on the vertex there is a very short horse-shoe-shaped 

 carina with the ends somewhat acute and tubercular ; prothorax 

 rounded and ampliate past the middle, marginate along the base, not 

 retuse in front, but having two oblique longitudinal impressions on 

 each side of the median part which unite at about the median part of 

 the disk and are prolonged from there into a median sulcus reaching the 

 base, between the two anterior depressions there is a slightly raised 

 longitudinal, smooth carina, or raised line, and the whole surface is 

 covered with conspicuously foveate punctures which are not con- 

 tiguous ; elytra ampliato-ovate, geminato-striate with the intervals 

 plane and having each one series of broad, slightly asperous 

 punctures ; pygidium closely punctate, pubescent ; metasternum 

 with a nearly obsolete, median impressed line; prosternum excavate 

 laterally ; anterior tibiae quadri-dentate outwardly, straight at tip, 

 apical spur not long, and curving outwardly. 



Female unknown. 



Length 3|- mm. ; width 2 mm. 



Not unlike 0. mcrus, but less ampliato-ovate and with the clypeus 

 not projecting in front ; like the latter it possesses a longitudinal 

 median carina in the anterior part of the prothorax which is, how- 

 ever, not retuse, and this carina is more in the shape of a raised 

 line than of an elongate tubercule as in 0. mcrus ; the cephalic horns 

 are differently shaped ; and the prosternum is more deeply impressed 

 laterally. 



The description of the male is made from Fahroeus' type labelled 

 '' Caffraria."

Head and prothorax bronze, shining but very densely pubescent,

 under side bronze maculated with testaceous ; head deeply and
