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 different 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. Deyrolle has sent it to me from Lake N’gami.
