1 think that these, although differing much in colour, are 

 only sexes of one species ; but in specimens from Mombasa 

 the males are coloured as the females, with the abdomen 

 Avholly testaceous red on the second and third tcrgites and a 

 yellow spot on each side of the first tergite, the fourth and 

 fiftii tergites are marked with black at the base. This 

 appears to be tiie usual colouring of the species from Harar to 

 Johannesburg. I have seen no females with the colouring 

 of P. pilifro7is, but several males from the Nandi phatcau 

 and Usanga. Phiianthus liinatus, Bingh.^ is allied to this 

 ijpecies, but not identical.
