57. Delattria viridi-pallens, sp. 188. 



Occurs in company with Petasophora thalassina on the Volcan 

 de Fuego. 



58. Thaumastura henicura, sp. 191. 



At Duenas the females of this species are much more com- 

 monly to be seen than the males. Occasionally, when flying, the 

 elongated tail-feathers are stretched to a considerable angle. 



59. Amazilia rieffen, sp. 198. 



60. Amazilia arsinoe, sp. 199. 



Both common in the forest about Yzabal. A. arsinoe is also 

 frequently met with about Duenas. I never observed it last 

 year. As I now find it in one of the spots which I then used to 

 visit most frequently, I judge that it is a migrant. 



61. Thaumantias candidus, sp. 200, 



Common on the Atlantic coast-region, about Yzabal, and 

 thence one day^s ride into the interior. 



62. Chlorostilhon osbei'ti, Gould. 



A pair of this species resort to the flowers about our house at 

 Duenas. 



One specimen was shot on the Volcan de Fuego at an altitude 

 of 5000 feet above the sea-level — the highest altitude at which 

 I have yet observed it.
