Hah. Mexico and S. Salvador ; absent apparently in intervening 

 conntricB, but re-appearing again in Colombia (Bogota) and the

 P. sdateri, as no specimen of the true P. nigriceps has as yet been 

 met with in Ecuador.

* The specimen is in poor condition, and may prove to belong to some other 

 species. The wing loolis like that of P. sdateri. 



t There is a Cumana in Venezuela, but I can find no such place marked on 

 the atlas as being in Bolivia. As Mr. Bridges only collected in Chili and 

 Bolivia, there may be some mistake iu the locality of the specimen.
