Genera of Humming Birds. 257 



Female. — Exactly the same, but slightly less brilliant. 



It is a very common species in Colombia, but rare in 

 Venezuela. From the last country, I have received several 

 specimens from Merida.

This species is allied to E. cupreiventris, but easily 

 distinguishable by the colour of its throat. Possibly it may 

 turn out to be a case of semi-albinism. 



Type unique in my Collection.

 which is probably a melanism of E. cupreiventris.
