instead of being black. This seems to me to be too trivial a

Length (horn excluded) 36 mm. 



Hab. Transvaal (Rustenburg, Waterberg) ; Southern Rhodesia 

 (Salisbury) ; Mazoe (var. Kirki). 



This species feeds " only on the gum exuding from certain species 

 of Acacia." (G. A. K. Marshall.)

Mentum long, fused with the ligula, very slightly sinuate laterally, 

 arcuate and not deeply incised in the centre in front, labial palps 

 somewhat long, especially the apical one which is cylindrical but 

 incurved, and truncate at tip ; maxillae somewhat robust, inner lobe 

 straight but sharp at apex, upper lobe very sharply triangular with 

 the outer margin penicillate, maxillary palps long, the last one
