and the base without having any posterior angle, or being sinuous ; 

 base slightly folded. Intervals of elytra quite smooth. 



Length 4-J— 5 mm. 



Hab. Southern Ehodesia (Salisbury). 



H. d'Orb. 



Onthophagus rasipennis, n. spec. 



Head and prothorax black ; elytra, epipleura included, entirely 

 light testaceous except the juxtasutural interval, which is for the 

 greatest part black ; pygidium black. Upper side nearly entirely 

 glabrous. Epistoma narrowly scooped, frontal part with an arcuate 

 carina, vertex with a nearly straight carina situated a little in front 

 of the anterior edge of the eyes. Prothorax smooth or very sparsely 

 punctulate, but with moderately large, more or less numerous 

 punctures scattered on the sides, and at times other punctures on 

 the disk ; the sides not sinuate near the posterior angles, or hardly 

 so ; base with a fold. Intervals of elytra entirely smooth or hardly 

 visibly punctulate. 



Length 3 1 — 4 V mm. 



Hab. Orange Eiver Colony ; Transvaal (Leysdorp, Waterberg, 

 Pretoria Distr.) ; Southern Rhodesia (Bulawayo, Matopos).

I cannot distinguish this species, which I have received from nearly 

 all the localities here mentioned, from 0. pallidipcnnis, F&hr.

Onthophagus producticollis, n. sp. 



Very near 0. verticalis, Fahr., differs in the prothorax and the 

 juxtasutural interval being not green-bronze, but brown-bronze; the 

 head has a fine frontal carina situated a little in front of the centre, 

 and a strong carina placed far behind the centre (instead of having 

 only a strong carina situated towards the middle or only slightly 

 further back) ; the median projection of the prothorax goes further 

 forward and is very regularly arcuate in the anterior part (instead of 

 being strongly sinuate in the centre) ; the size is also a little larger. 



Length 7^-9 mm. 



Hab. Natal (Estcourt).

I do certainly not think that this will prove a distinct species. It 

 is even doubtful to me if it should rank as a variety of 0. verticalis. 

 I have examined more than two hundred examples from Estcourt, 

 and they all merge into 0. verticalis. L. P.
