Male : Chocolate-brown, a little darker on the prothorax than on 

 the rest of the body, sparingly sprinkled above and beneath with 

 slightly elongated white scales ; head and prothorax similar in shape 

 to that of M. formosus, but the latter is not so deeply or closely 

 scabroso-punctate ; the elyti-a are similar, but the shape of the hind 

 tibige is very different ; the spine of the trochanters is small, and the 

 apical spine of the femora beneath, under the knee, is conspicuous ; 

 the tibige are deeply grooved beneath, the outer edge is very sharply 

 angular near the knee and ends in a sharp, curved mucro at apex, 

 and the inner edge is simple, while the upper carina is conspicuously 

 keeled ; hind claws single, simple. 



Female unknown. 



Length 7 mm. ; width 4 mm. 



Hab. Cape Colony (exact locality unknown). 



I have seen three examples only, collected by Drege, the locality 

 of which is not recorded, but I think they are from Namaqualand.
