FAMILY TROCHILIDAE 347 



Females (8 from Colombia and Ecuador), wing 62.5-64.2 (63.3), 

 tail 37.0-40.0 (39.2, average of 7), culmen from base 24.5-26.9 (25.6) 

 mm. 



Resident. Found locally on the upper Rio Jaque (mouth of Rio 

 Imamado), and on the lower slopes of Cerro Pirre (head of Rio 

 Seteganti at 450 meters, and Cana at 550 meters) . 



This, the common race of the species in western and northern 

 Colombia, where it is widely distributed along the western coast, 

 continues west from Choco across the international boundary to the 

 upper Rio Jaque. Here I secured 2 males feeding low in forest on 

 March 29 and April 10, 1947. On Cerro Pirre, Goldman collected a 

 male at 550 meters near Cana, June 4, 1912, and we netted a male at 

 450 meters elevation near the head of the Rio Seteganti, February 1, 

 1961. 



These are the only records known at present for this race in the 

 Republic. The one taken by Goldman had the stomach filled with 

 remains of insects, among which were those of a mosquito and other 

 small diptera, bits of tiny beetles, including a staphylinid, and frag- 

 ments of small hymenoptera.
