white in the male and having a broad, basal, transverse black 

 band, yellow in the female and without trace of a black transverse 

 band ; propygidium and abdomen clothed with scales ; head deeply 

 punctured, setulose, clypeus acuminate, somewhat sharply bi-dentate 

 at apex ; prothorax diagonally attenuate laterally in the anterior 

 part, emarginate from the median part towards the base, not much 

 convex, not sulcate longitudinally at middle, very closely punctate 

 and clothed with dense, long black hairs ; scutellum long, sharp, 

 punctulate and without scales ; elytra elongate, gradually attenuate 

 from the shoulder towards the apex, depressed on each side of the 

 suture before the median part, humeral angle distinct and very 

 lateral, and continued as far as the apex in a rounded, not highly 

 raised costa, feebly punctate and slightly bristly but with the 

 sutural and marginal row of bristles longer and stiffer than those 

 on the discoidal part ; pygidium vertical in the male ; outer teeth of 

 anterior tibiae nearly equi-distant but with the apical one smaller 

 than the intermediate and the basal ones ; hind femora not much 

 thickened in the male ; tibiae as long as the thighs, slightly swollen 

 at about the median part, simple, apical spur moderately long ; basal 

 joints of tarsi short, transverse, somewhat triangular, fifth joint longer 

 by one-half than all the others taken together, slightly tri-dentate 

 beneath, claw nearly as long as the fifth joint, curved and emarginate 

 at the base beneath ; in the female the hind legs are hardly swollen, 

 but in both sexes they are sprinkled with scales and are bristly and 

 hairy.

 Similar in shape to P. namaqua ; the head and prothorax are 

 black, the latter has a very distinct lateral margin of white scales 

 in both sexes, but the anterior margin has none, and in the 

 basal one there is a short median band of them above the scutellum 

 which is densely scaly ; elytra reddish brown, opaque ; the 

 abdomen and pygidium are clothed with white or flavous scales, 

 but the edges of the pygidium are narrowly denuded all round, 

 and in the centre there is a longitudinal denuded line reaching 

 from base to apex in both sexes, as a rule, but in some female 

 examples this band is hardly distinct ; the sculpture and vestiture 

 of the head and prothorax are similar to that of P. namaqua, but 

 the elytra are not so depressed across the sutural part at about
