about one-fifth of the whole, and in the anterior part there is a small 

 black spot, often obliterated ; scutellum black, elytra with a very 

 broad yellow band invading the black background to such an extent 

 that the latter is reduced to a quadrate dorsal patch more or less 

 deeply incised on each side, prolonged for a short distance as a nar- 

 row band along the suture, and coalescing there with a transverse or 

 slightly arcuate patch as broad as the anterior one but of only half 

 the length, in addition to these two discoidal patches there is a 

 Lateral supra-marginal small black patch or spot situated past the 

 median part ; the pygidium is black with a flavescent triangular 

 patch at apex ; the under side is black and immaculate. Clypeus 

 deeply emarginate in front, closely punctulate, frontal part deeply 

 and numerously variolose punctate, punctures on the prothorax also 

 numerous and deep ; those on the elytra plainly seriate punctate in 

 shiny examples, less distinctly so in the opaque ones ; pectus and 

 inner part of legs pubescent ; sternal process horizontal, ampliate 

 rounded laterally but only moderately deeply arcuate in front. 



Length 15|-17£ mm. ; width 9-9£ mm. 



Hab. Transvaal (Waterberg), Southern Ehodesia (Middle Lim- 

 popo), British Bechuanaland (Macloutsie). 



The figure of P. arborcsecns, Vigors, does greatly agree with this 

 insect, the only difference being the absence of the post-median, 

 supra-lateral round black patch.

Very closely allied to P. laticincta, but very shiny on the upper 

 side instead of being opaque, the black markings are exactly 

 similar, and the prothorax appears more deeply and more numerously 

 punctate, owing perhaps to the absence of the opaque indumentum ; 

 the pygidium is also flavo-rufescent in the centre. The genital 

 clasps of the male, although of the same pattern as those of laticincta 

 differ in being a little shorter and less slender in the anterior half.
