This species is abundant in Colombia, but rarer elsewhere. 

 I am of the same opinion as Mr. Elliot about the difficulty 

 of separating the specimens from Venezuela, Peru and 

 Bolivia, having in my collection some specimens from 

 Colombia, exactly like those from Venezuela and Bolivia, 

 known as H . otero and H . splendens. They vary very much 

 in colouration. 



Type of Bourcier from Colombia in my collection. It is 

 labelled Leadbeatera leadbeateri. It was dedicated by him 

 to Mr. John Leadbeater.
