S . Black, with the antenna and the tegulaB only red, in the former 

 however the first and the second joints are black ; abdomen nearly 

 sessile, the first segment with a narrow apical fringe of sub-flavescent 

 hairs with a white tinge, second segment with an equally narrow 

 apical border, third segment completely covered by a band of the 

 same colour. 



It is not necessary to repeat here the description of P. flahellata, 

 Fab., with which the present species is intimately connected. It 

 differs however from it, provided the South African examples with 

 black antennae and pro- and mesonotum are the same species, by 

 the brick-red antennae, the two basal joints of which only are black ; 

 the entirely black thorax with the exception of the tegulge which are 

 also brick-red ; the apical pubescent bands of the first, second, and 

 third abdominal segments is also more yellowish than in what I take 

 to be the Cape Colony form of P. flahellata. I may point out that 

 in the examples from the latter locality the apical white border of 

 the second segment disappears towards the middle. 



Length 14 mm. ; width (wings expanded) 25 mm.

$ . Black, with the thorax red ; abdomen sub-sessile, elongate 



ovate, basal segment with a broad, apical white band, second and 



third segments with a broad, white, apical band widely interrupted 



in the centre. Upper side of head and prothorax not clothed with 



an appressed pubescence, but moderately bristling with black, and, 



occasionally, white setae, abdomen somewhat densely setaceous.
