ocelli are much further from the eyes than from each other 

 and the clypeus more narrowly rounded.

I 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 

 wholly testaceous red on the second and third tergites and a 

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

 fifth tergites are marked with black at the base. This 

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

 Johannesburg. I have seen no females with the colouring 

 of P. pilifrons, but several males from the Nandi plateau 

 and Usanga. Phiianthus limatus, Bingh., is allied to this 

 species, but not identical.
