Humming-birds of Guatemala. 261 



5. Petasophora delphin.e. 

 Coban, Vera Paz. Novembei'. 



This Humming-bird seems to have been quite unknown at 

 Coban previously to the present specimens being collected. The 

 first was shot by my collector, Cipriano Prado, among some 

 Salvia, in one of the mountain-hollows near Coban. I after- 

 wards visited this place and saw one bird, but did not succeed 

 in shooting it. Salvia being in flower in November, their 

 blossoms are sought after by nearly every species of Humming- 

 bird near Coban, this among the rest. It is a rare species 

 even at Coban, and though much looked for by the Indian boys 

 in consequence of my offers of reward, but few specimens were 

 obtained. 



The females appear only to differ from the males in being 

 smaller in size, the colouring of the ear and throat being quite 

 as brilliant. Three males to one female appears to be about the 

 proportion of the sexes. 



6. Cyanomyia cyanocephala. 

 Duenas and Coban. 



This species is common at Dueiias, but its numbers at Coban 

 are very much smaller. The sex of the young males seems 

 sufficiently indicated by the colouring of the head. 



7. Eugenes fulgens. 

 Duenas, Coban, and Tactic. 



This species is also rare at Coban. The place described as 

 frequented by Amazilia dumerillii is the spot where I have 

 found this species in greatest numbers ; indeed, with two excep- 

 tions, I have never met with it elsewhere near Duenas. It is a 

 most pugnacious bird. Many a time have I thought to secure 

 a fine male, which I hud perhaps been following from tree to 

 tree, and had at last seen quietly perched on a leafless twig, 

 when my deadly intention has been anticipated by one less so 

 in fact, but to all appearances equally so in will. Another 

 Humming-bird rushes in, knocks the one I covet off his perch, 

 and the two go fighting and screaming away at a pace hardly to 

 be followed by the eye. Another time this flying fight is main-
