The name Phonasca humilis, proposed by Dr. Cabanis for the Costa-Rica bird of this 
form, was based upon a young male specimen which is said to have the characters of 
i. minuta, but to be much larger. We do not possess Costa-Rican examples of this 
bird; but we have a fair series from other parts of Central America, from Guatemala to 
Panama, and others from various parts of South America, including Guiana, the home of 
the typical #. minuta. We notice a slight difference in size between the Guiana birds 
and those from other places, the former having a wing averaging about one tenth of an 
inch shorter; but, failing other differences, we do not consider this any ground for 
dividing the species. It must be remarked, however, that the bird we have described 
as the female or young male has rather less cinereous on the throat and belly than 
true females collected by Whitely in British Guiana; the difference is not of much 
importance. 
The names E. strictifrons proposed by Strickland and LZ. pumila by Bonaparte, in 
the year 1851, both apply to EL. minuta, as Mr. Sclater has long ago shown ?. 
The obvious diagnostic character of E. minuta is its white crissum; this is only 
shared in the whole genus by EL. anne, a species at once separable by its rufous head. 
In Guatemala L. minuta appears to be a rare bird, as only one other specimen has 
reached us from there since the single male example was obtained by Salvin at Coban 
in November 1859. In Nicaragua Belt secured only one specimen ; but from various 
points of the State of Panama we have received skins of both sexes from our excellent 
collector Arcé. |
