Humming-birds of Guatemala . 
J 9. DeLATTRIA VIRID1PALLENS. 
Volcan de Puego. September 18tli. 
This Humming-bird seems to keep entirely to the forests of 
the Volcano. 1 have never met with it in the plains below. 
During the months of August and September, the localities of 
the various species of Humming-birds are usually as follows:— 
Among the trees on the south-eastern side of the lake are 
Amazilia dinnerillii, Thaumastura lienicura (mostly females), 
Campijlopterus rufus, Heliomaster longirostris , Chlorostilbon osberti 
(in small numbers), Cyanomyia cyanocephala, and Trochilus 
colubris. 
On the liill-side to the south-westward of the lake are great 
numbers of Campylopterus rufus , and among the willows close 
to the water the males of Thaumastura lienicura congregate. 
About the Convolvulus-trees in the llaiio at the foot of the 
Volcano are found Eugenes fulgens , Amazilia dumerillii , Thau¬ 
mastura lienicura (in small numbers), Trochilus colubris (very 
commonly towards the end of September), Cyanomyia cyanoce - 
phala, Heliomaster longirostris (rarely occurring). 
Entering the first barranco that opens out into the plain, we 
meet with Campylopterus rufus , Myiabeillia typica , Heliopedica 
melanotis , and, a little higher up, Petasophora thalassina and 
Delattria viridipaliens. Of course, occasionally a species is found 
notin its place as here indicated; for instance, I have seen in 
the first locality a single specimen (the only female I have met 
with) of Eugenes fulgens, and another high in the Volcano. ^ I 
have also seen a single Petasophora thalassina out on the llano. 
These localities must therefore be taken as only generally 
indicating the distribution of the species found about Duenas. 
This is one of the commonest species at Coban. It may 
readily be recognized by the peculiar harshness of its note.

A single specimen was brought to me by a boj. ne\ei 
saw the species myself at San Geronimo.
