emits past the median part a transverse yellow band stopping 

 slightly short of the suture (flaviventris), and edging thus an elongate 

 quadrate discoidal part which is either immaculate, or is marked 

 with two yellow patches near the scutellary part ; this band is also 

 often interrupted in the middle, in which case the black dorsal part 

 bears on each side two juxta-sutural yellow patches; pygidium 

 brownish purple and with six minute white spots ; under side either 

 brownish red or black with a few yellowish macules, or bright yellow 

 with the sides reddish, and a spot or a very short silvery band on 

 the upper side of the abdomen and the epimera; clypeus closely 

 aciculate, head sparingly punctate, the upper part is almost 

 impunctate, except for a few faintly seriate punctures in the 

 posterior part ; glabrous underneath except on the presternum ; 

 the last abdominal segment is closely aciculate, the others have 

 a few lateral punctures ; the sides of the pectus and legs are 

 strigillate ; the horizontal sternal process is almost orbicular and 

 without suture. 



This is the most protean of the South African Cetonids. The 

 colour of the upper side changes from opaque velvety black to 

 shiny olive-green ; that of the under side varies equally, and is dark 

 brown or almost black and with very few yellow macules in the 

 species with opaque upper side in which the transverse post-median 

 transverse band is interrupted, and bright yellow except along the 

 upper sides in those in which the transverse band is entire. 



P. flaviventris, Gory and Perch., is a variety in which the prothorax 

 and scutellum are immaculate, the transverse band of the elytra 

 complete and the discoidal background immaculate. I am of 

 opinion that it is really the type form, and that P. sinuata is the 

 variety. Kraatz has figured and described some 19 varietal forms 

 (Deutsch. Entom. Zeitschr., 1885, p. 341, pi. v.). I could add to 

 this number, but in all of them the genital clasps are absolutely 

 alike. 



Length 21-24^ mm. ; width 12-15 mm. 



Hab. The whole of South Africa, except the South- Western part 

 of the Cape Colony ; also Angola, and Central and Eastern Africa as 

 far north as Somaliland.
