A single specimen of this species was collected at Caicara, July 

 4th, 1898. None were observed on my more recent expeditions. 



In the American Museum is a series of ten specimens collected by 

 Klages sent from Suapure and Maripa on the Caura River, and two 

 examples of Progne chalybea chalybea, one from La Union and the 

 other from Maripa, indicating that this is the common form on the 

 Caura, while my own experience showed P. chalybea to be the common

The American Museum specimens of P. tapera immaculata from 

 the Caura river were collected during April, May and December.
