I have collected both sexes of this species in Costa Rica, 

 in 1877. I have also some specimens collected by Arce, in 

 Veragua, by Buckley, in Ecuador, one specimen collected by 

 Whitely, at Huiro, Peru, and others from Colombia. To me 

 there is no doubt whatever that P. yaruqui, is identical with 

 this species, and I believe that P guyi will probably turn out 

 to belong also to the same species.
