Hab. Mexico, Omilteme in the Sierra Madre del Sur, Guerrero, Mexico (Mrs. H. H. 
Smith 2), 
The males of a series of specimens obtained by Mrs. Herbert Smith at Omilteme, in 
the high mountain-range called the Sierra Madre del Sur, all agree in having the 
throat violet instead of rosy red as in the well-known D. henrici. For this reason we 
separated this form under the name it now bears, calling the species after its energetic 
discoverer. 
Omilteme is a small hamlet situated at an elevation of about 8000 feet above the 
sea, where Mr. and Mrs. Smith spent the months of July and August 1888.

& F. D. G.), Pie de la Cuesta in San Marcos, Santa Maria near Quezaltenango, 
Toliman (W. B. Richardson § °). 
This pretty species, distinguished by the delicate green colour of the throat, was 
described from specimens obtained at Coban in Vera Paz, where numerous specimens 
were subsequently secured by Skinner’s collectors and by ourselves. 
Most of our examples were, however, shot in the upland forests of the Volcan de 
Fuego, where the bird is common up to an elevation of about 7000 to 8000 feet. It 
frequents the same woods as Petasophora thalassina, never leaving the oak-forests, and 
is not found with Eugenes fulgens and other species in the more open plains. It 
probably occurs in all suitable places over the highlands of Guatemala, as we also met 
with it in the higher mountains of Vera Paz, and Mr. Richardson has sent us a series 
of specimens from the Altos of Guatemala, close to the frontier of the Mexican State 
of Chiapas. In Northern Nicaragua its place is taken by the next species.
