Male : Black, prothorax clothed with a dense ilavescent or 

 whitish, slightly ianuginose pubescence ; elytra with four bands of 

 appressed, squamulose hairs of the same colour, pygidium and 

 abdomen clothed with similar hairs, pectus and legs densely hairy ; 

 head and prothorax scabrose, the clypeus is straight laterally and 

 also at apex ; the outer angles are very distinct, and the apical 

 margin is plainly reflexed ; scutellum hairy ; elytra very little 

 broader than the prothorax at the base but very plainly narrowed 

 laterally from the shoulder towards the apex, they are very closely 

 punctured and have on each side two somewhat distinct costules, 

 and three intervals filled with the appressed, squamose hairs 

 in addition to the outer marginal band, but the third one is often 

 obliterated, or very indistinct ; pygidium large and very slanting 

 forwards, being almost sub-horizontal ; hind legs moderately 

 robust, hind tibiae sub-mucronate inwardly at apex and having an 

 apical spur, anterior tibiae strongly tri-dentate with the two basal 

 teeth closely set but not connate, and the basal one shorter, but 

 broader than the intermediate ; all the claws are double and un- 

 equal, the anterior ones are both cleft, the inner one of the anterior 

 being short and very massive and less deeply cleft than the other, 

 in the intermediate and posterior legs the weaker claw is very small 

 and simple, and the stronger, and somewhat elongate one, is deeply 

 cleft. 



Female : I have not seen the female, but Burmeister says that she 

 is smaller, narrower, and darker than the male ; the fore margin of the 

 clypeus is not much raised, and the squamose hairs are not so dense. 



Length 8-10 mm. ; width 4-|-5i mm. 



Hah. Cape Colony (exact locality unknown); Natal (Frere).
