This interesting fly agrees most closely with P. grisea Alex- 

 ander^ . from Panama from which it differs in the venation, 

 the lack of a distinct narrow pleural stripe, and in having the 

 scapal segments of the antennae quite distinct in color ; the 

 color of the posterior legs of grisea is still unknown. P. ptd- 

 chricornis Alexander- from British Guiana is likewise allied 

 to geniculata in the uniform brown tarsi but differs in the 

 possession of a broad pleural stripe, the darker wings with the 

 radial crossvein set far back from the tip of R-^^, etc.
