olivaceous with the sides of the prothorax and elytra flavescent 

 (frenata) ; upper lobe of maxillae dentate, tooth simple, inner lobe 

 toothless ; clypeus arcuately and somewhat deeply emarginate, much 

 more closely punctate than the frontal part on each side of which 

 is a white band ; prothorax sparsely punctulate ; scutellum im- 

 punctate ; elytra with small, seriate punctures ; pygidium with a 

 transverse basal white band reaching from side to side, and a 

 broader, slanting lateral one occasionally divided into two ; each abdo- 

 minal segments with a white band reaching from the upper part to 

 three-fourths of the length, but as often as not interrupted at a short 

 distance from the upper part, and occasionally with the lower portion 

 obliterated ; sides of pectus and epimera either completely white 

 or maculated with white ; femora streaked with white ; sternal pro- 

 cess horizontal, not ampliated, or rounded at the tip, and without 

 suture ; pectus and legs variolose punctate, femora and tibiae fringed 

 with flavescent hairs. 



In the type form the white bands of the under side are often 

 nearly obliterated ; this form seems to be restricted to the South- 

 western districts of the Cape Colony. In Natal and the Orange Eiver 

 Colony, the colour becomes lighter, the thorax is greener, and it then 

 resembles P. cincta, from which it is easily distinguished by the 

 horizontal sternal process not compressed laterally. 



Length 17-22 mm. ; width 9-13 mm. 



Hab. Cape Colony (the whole of the Eastern and Central 

 Provinces, but not the Western part, to the east of Knysna) Natal, 

 Transvaal, Southern Ehodesia (Manica, Plumtree, Bulawayo, 

 Salisbury).
