FAMILY TYRANNIDAE 565 



Boca de Paya on the Rio Tuira, and on the Tuquesa where it joins 

 the Rio Chucunaque. The species is also known at Punta Sabana in 

 the lower valley, and at Garachine on the coast. Eisenmann has 

 recorded it at Santa Fe, and it is known at Cana on Cerro Pirre. 



Stomachs of those that I have examined have contained insect 

 fragments, and a few small seeds. 



On February 26, 1950, near the Rio Corotu above Chiman I col- 

 lected one as it placed bits of vegetable fiber in the foundation of a 

 nest. I was interested to find that this bird was a male. Belcher and 

 Smooker (Ibis, 1937, pp. 244-245) describe a nest of the slightly 

 larger race of Trinidad (Myiopagis g. trinitatis), placed in twigs at 

 the end of a branch of a mangrove in the Caroni marshes, Trinidad, 

 as like that of the Yellow-bellied Elaenia, but smaller, and without the 

 feather lining found in that species. The two eggs, with a pale 

 creamy-white ground color, had markings "of spots and blotches of 

 deep red-brown with underlying ones of lavender, forming a ring 

 toward the larger end." They measured 17.9x14.1 and I7.2x 

 13.9 mm. 



This race was described as from "Venezuela" collected by Chris- 

 topher Wood, without a more definite locality. The type specimen, in 

 the American Museum of Natural History, is marked Cartagena, 

 Colombia, which is accepted as the type locality. Lawrence named it 

 "in compliment to my friend, J. H. Mcllvain, Esq., of Philadelphia, 

 an ethnologist as well as ornithologist, to whose liberality Mr. Wood 

 is indebted for the opportunity to make the collection."
