This species is very abundant in Venezuela, Colombia, and 

 Ecuador. The males have been named by Gould P. iolata, 

 and the name of P. anais has always been given to the 

 females, but I am certain that they all belong to this species. 



I have a very large series of both sexes from Venezuela. 

 " Rojas," Ecuador and Bolivia, " Buckley," Peru, " Whitely," 

 Colombia, " Salmon," and others. 



One of my male specimens, from Colombia, has all the 

 upperside and flanks brown, with green reflections, the tail 

 feathers brownish-green, with the subterminal band dark 

 blue, the undertail-coverts pale green, edged with white. 

 The remainder of plumage is like the ordinary male of that 

 species. 



Although I consider also Petasophora corruscaus, Gould, 

 and rubrigularis, Elliot, as accidental varieties of coloura- 

 tion of P. anais, I give below the descriptions of the two 

 specimens in my collection, agreeing with the original des- 

 criptions of Messrs. Gould and Elliot.

Exactly like P. anais, with the centre of throat bright 

 metallic rosy-bronze. Undertail-coverts buff, with bluish- 

 green in centre.
