no trace of it at Chiriqui, the country of Z. adorabilis, nor from Costa Rica, where 
L. helene is found. 
L. delattrit has two near allies in L. regulus and L. stictolophus, but it differs from 
both in its narrow crest-feathers, hardly any of which have a trace of a dark terminal 
spot.

The range of Lophornis helene extends much further north than that of any other 
species of the genus, and even reaches the middle of the State of Vera Cruz, where so 
many purely neotropical birds find the northern limit of their distribution. 
It was not in Mexico, as it has been sometimes stated, that Delattre discovered this 
bird, but in Vera Paz, the only Department of Guatemala where it is found. In the 
month of November it is not uncommon near Coban, feeding from the flowers of the 
Salvie, the favourite resort of so many species of Humming-Birds. The flight of 
LL. helene is very rapid, and hardly to be followed by the eye as it darts from flower to 
flower. Its cry is peculiarly shrill and unlike that of any other Humming-Bird, so 
that its presence in any place may at once be detected by a skilled ear. ‘The females 
are either very much rarer than the males, or, which is probably the case, less in 
evidence. During a month spent at Coban only one female was secured to seventeen 
males. 
M. Boucard observed this species during his residence in Mexico at several places 
near the town of Cordova, The same traveller subsequently met with it in Costa Rica.
