Bronze-green, with the usual clothing of scales, which, however, 
are flavescent on the upper side, and very few in number on the 
prothorax which is very coarsely punctured and clothed with very 
long, erect, dense flavescent hairs; the head is also hairy, and the 
scales on the clypeus are also somewhat hair-like, the latter is 
moderately emarginate in front and not acuminate or angular 
laterally ; the median impression is absent in the three examples at 
my disposal, and there are therefore no smooth walls, but the supra- 
basal, supra-lateral patches are distinct; the elytra are very cylin- 
drical and more costulate than the other species, the three dorsal 
bands of slightly flavescent scales are sub-obliquely interrupted past 
the median part in a more or less indistinct manner ; scutellum im- 
punctate; anterior tibiz bi-dentate outwardly; antennz chestnut- 
red, the two ultimate joints of the pedicel not aculeate.

I have seen the type only of this species, which differs from my 
examples of P. gréndahlt by its size, which is about one-third 
larger; the pubescence of the prothorax is longer, more lanuginose, 
without any traces of scales, and the punctuation is very much 
narrower ; the costules of the elytra are much less in relief, and the 
scales are slightly finer; the anterior tibia are bi-dentate. 
T did not possess P. derzdens at the time I examined the type or 
co-type of P. pilosicollis, Boh., nor did I think of verifying then the 
number of the antennal joints. This species might thus prove to be 
identical with P. deridens, Boheman’s description agreeing pretty 
fairly with it, but the co-type seen was certainly different. Boheman 
gives also to that species a vast area of distribution, 7.e., ‘ Caffraria 
tota.’’ Now such is really not the case, and it is thus probable that
