narrower and the anterior lateral denuded patch is connected with 

 the black discoidal part ; the punctures on the upper side are 

 setigerous. 



Length 18-29 mm. (horns excluded) ; width 11-14 mm. 



Hab. Natal (Durban, Maritzburg, Karkloof) ; Transvaal (Rusten- 

 burg, Pretoria, Lydenburg, Waterberg, Zoutpansberjj;) ; Mozam- 

 bique (Lourenco-Marquez) ; Southern Rhodesia (Salisbury, Enkel- 

 doorn, Sebakwe, Manica, Mazoe, Bulawayo) ; Ovampoland ; 

 Northern Damaraland. 



About Salisbury this species is specially partial to the flowers of 

 a small tree, name unknown ; but also occurs on Cassia pods ; at 

 Bulawayo and Mazoe it is found only on Acacia gum (G. A. K. 

 Marshall).

Mentum broad, as long as the ligular part which is narrower, parallel 

 laterally with the outer angles moderately rounded, and emarginate 

 at apex, the palps cavity reaches from the mentum proper to the 

 apical part, and is very broad and impinges considerably on the 

 outer face, maxillae robust, inner lobe mucronate in the $ , and 

 with a long, slender hamate tooth in the ? ; upper lobe styliform, 

 mucronate, not dentate in both sexes; head of 3 with two hamate 

 teeth on the margin of the vertex, and the outer margin raised into 

 a sharp protuberance above the eyes, the clypeus is broader at the 

 apex than at the base with the outer angles acuminate, and nearly 

 the whole of the anterior margin is produced into a curved horn 

 narrowed at about half its length, and expanding there into a 

 bifurcate process more or less strongly divaricating ; in the ? the 

 clypeus is simple, carinate laterally, but with the lateral part bulging 

 beyond the upper carina; prothorax of the normal shape, bi-sinuate 

 laterally and only slightly arcuate above the scutellum ; elytra 

 elongated, gradually attenuate towards the posterior part ; anterior 

 tibiaa uni-dentate at apex in the 3 , set inwardly with numerous 

 sharp teeth, lower edge of outer face of anterior femora densely 

 pubescent in both sexes, but in the ? the anterior tibia' are 

 strongly tri-dentate outwardly and simple inwardly ; under side 

 nearly glabrous, sternal process horizontal, arcuately rounded at 

 apex, without any traces of suture, and grooved longitudinally 

 in the basal part only. 



The type form of the only species included in this genus seems 

 to be restricted to the South African area, but very slight varieties 

 of the same occur in Central and East Africa.
