acuminate in the middle, it is covered with round, not closely set, 

 moderately deep setigerous punctures ; elytra sub-ampliato-ovate, 

 very narrowly punctato-striate, striae not distinctly geminate, 

 intervals plane and having each two series of moderately closely 

 set granules turning to scabrose punctures towards the posterior 

 part ; pygidium closely pitted ; metasternum slightly acuminate at 

 tip, very closely punctured, median longitudinal line moderately 

 distinct ; inner angle of anterior tibiae very briefly spinose. 



Length 3f mm. ; width 2 mm. . 



Eesembles a little 0. Utigiosics in having no trace of cephalic 

 carinae, but the genae are more auriculate, and the clypeus, instead 

 of being acuminate, is semicircular ; it is also much more densely 

 pubescent, the prothorax is not so closely punctate, the punctures are 

 much broader, and the sculpturing of the intervals of the elytra 

 differs. 



Hab. Southern Ehodesia (Salisbury). 



Onthophagus pkobus, n. spec. 



Black, shining, briefly pubescent, elytra sub-sanguineous red with 

 the suture and a transverse line along the base black, and with 

 occasionally a lateral transverse patch of the same colour situate 

 past the middle on the three or four outer intervals, antennae black, 

 club fuscous ; head and clypeus covered with deep, moderately 

 closely set scabrose punctures, genae distinctly auriculate, clypeus 

 emarginate laterally near the genae, incised triangularly in front 

 and with the angles of the incision sharp and slightly recurved, 

 no frontal carina in either sex, but on the base of the vertex there 

 is a very little raised sinuate one often indistinct ; prothorax convex, 

 ampliate laterally, marginate all round, rounded at base and covered 

 with scabrose punctures set moderately close together, but more 

 rounded and less scabrose in the posterior part which has no trace 

 of any longitudinal impressed line ; elytra slightly ampliato-ovate, 

 narrowly geminato-striate, intervals plane and having a double series 

 of punctures distinctly scabrose and more closely set in the anterior 

 than in the posterior part, second interval not wider than the third, 

 humeral callus hardly distinct ; pygidium very closely punctured ; 

 metasternum deeply punctured and having a smooth, distinct median 

 longitudinal impression. 



The female differs from the male merely in the absence of a spine 

 in the inner part of the anterior tibiae. 



Length 3i-4 mm. ; width 2 mm.
