OREOPYRA. 



Oreopyra, Gould, P. Z. S. 1860, p. 313, Salv. Cat. Birds Brit. Mus. xvi. p. 305. 



The four species included in this genus all belong to the highlands of Costa Rica and 

 the western mountains of the State of Panama adj oining. In these countries they nearly 

 take the place of Delattria, most of the species of which are found further north. 



From Delattria, Oreopyra diflPers in having the sexes widely distinct in coloration, 

 and in having the top of the head of the males glittering in contrast to, instead of in 

 uniformity with, the back. The tail in both genera is nearly uniform, the females only 

 exhibiting pale tips to the outer rectrices.

Warszewiez was the discoverer of this species during his visit to the Cordillera of 

 Chiriqui, where he obtained five specimens — a male and four females. The latter were 

 described by Gould in 1850 as Trochilus (%) castaneoventris'^, and subsequently figured 

 in his ' Monograph of the Trochilidse ' as Adelomyia % castaneiventris ^. The male was 

 not characterized until 1860, when Gould placed it in a separate genus as Orecypyra 

 leucaspis ^. The real relationship between these birds was not suspected until we 

 received a large series of skins from our collector Arce, and the point was discussed 

 by Salvin in 1870 ^. In point of priority A. castaneiventris is several years older than 

 0. leucaspis ; but as the former name was founded on female specimens, and as all the 

 birds of this sex are exceedingly alike in the species of Oreopyra, the latter name based 

 upon the male had better be used.
