 effulgence ; the clypeus, median segment, coxae, trochanters, and 

 base of tlie femora with a thin silvery pile ; the abdomen with 

 bands of cinereous pile at the base of the lst-5th segments above 

 and below, the apical segment entirely covered with cinereous 

 pile and studded with stiff black hairs. The form of the median 

 segment varies, it is sometimes long with the apex rounded, steep,

$ . Closely resembles P. canifrons and P. perplexus. Smith ; 

 differs in the median segment being square not rounded, its 

 lateral angles being produced into tubercles, and its posterior face 

 being markedly concave. Like canifrons, this species is black, 

 with bands of plumbeous grey pile at the base of the segments of 

 the abdomen ; wings fuscous, the 2nd and 3rd cubital cells equal.
