Eab. Mexico, Omilteme in the Sierra Madre del Sur, Guerrero, Mexico (Mrs. E. H. 

 Smith 1 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. henrid. 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.

 Tollman ( W. £. Bichardson ^ ^). 



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.
