the central part in front of a highly raised transverse clypeal lamina 

 which is slightly arcuate but produced on each side into a sharp, 

 projecting angular process, and situated between the median part of 

 the eyes, there is no frontal carinule ; prothorax deeply sinuate 

 laterally behind and with the posterior angles distinct, highly 

 convex, retuse in front, bi-impressed in the middle of the anterior 

 part, the two impressions surmounted by a small but very distinct 

 tubercle, and having in the centre a very deeply emarginate, almost 

 bi-tuberculate ridge, it is covered with very closely set scabrose 

 punctures in the median part of the disk, and with granules on the 

 other parts of the surface, and clothed with a very short, silky, 

 whitish pubescence, the base is plainly grooved, and the edge of the 

 margin has a series of punctures ; elytra not wider than the prothorax 

 at its broadest part, striaa narrow and shallow, intervals plane, 

 closely punctured and pubescent ; pygidium nearly as broad as long, 

 covered with broad, deep, nearly equi-distant punctures, and clothed 

 with a dense greyish-white silky pubescence ; under side moderately 

 pubescent ; inner spur of anterior tibias long, the basal part is 

 directed inwardly almost at right angles with the apex of the tibia, 

 and there curves strongly outwards. 



Allied to 0. clispar, but different in colour and sculpture ; the 

 shape of the inner spur of the anterior tibiae of the male is very 

 singular, and unlike that of any other species of Onthophagus known 

 to me. 



Length 7-9^ mm. ; width 4^—5^ mm. 



Hab. Southern Rhodesia (Sebakwe).

" Little shiny, head and prothorax obscurely coppery-bronze, 

 elytra piceous black and marked on each side with a large, hutoieral 

 testaceous macule, pygidium black ; upper side very briefly flavous 

 pubescent. Head very densely punctate, clypeus narrowed and 

 truncate in the anterior part, frontal part not carinate, vertex very 

 briefly carinate between the eyes ; prothorax very densely and deeply 

 punctate, the punctures simple in the disk, very slightly asperous 

 towards the sides, the intervals between the punctures slightly rugose, 

 it is depressed on each side in the anterior part, broad in the middle, 

 and briefly subcarinate obliquely on each side next to the depression, 

 sides very slightly sinuate behind, minutely marginate in the middle 

 only, the margination except at that point being very indistinct ; 

 elytra thinly striate, intervals plane, extremely closely and strongly
