A common species, apparently, at the Cape and in most collec- 

 tions. After a careful examination of a series of examples, I 

 believe that the form here described is specifically distinct from 

 others noticed in this paper : it is more globose in general form 

 than, as well as diflPerent in coloration and in markings from P. 

 guttata, Fab. ; the thorax, as well as the head, is more distinctly 

 punctured, and the legs are rufous and the elytra rufo-ferrugi- 

 nous instead of black. It more nearly approaches in form P. 

 20-guttata, and in fact only seems to differ from it by the ob- 

 scurer and almost obliterated markings on the thorax, the much 

 smaller size of the markings, and the difference of the coloration 

 of the elytra. I have considered, however, that the species are 

 distinct, inasmuch as in the series before me I can trace no 

 appearance of an intermediate pattern.

A very common species at the Cape and all through the south 

 of Africa, and which would seem to be subject to little variation 

 in pattern. M. DeyroUe has sent it to me from Lake N'gami.
