57. Delattria viridi-p aliens, sp. 188. 
Occurs in company with Petasuphora thalassina on the Volcan 
de Fuego. 
58. Thaumastura henicura , sp. 191. 
At Dueiias 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 riefferi, sp. 198. 
& 60. Amazilia arsinoe, sp. 199. 
Both common in the forest about Yzabal. A . arsinoe is also 
frequently met with about Duefias. 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. Thanmantias Candidas , sp. 200. 
Common on the Atlantic coast-region, about Yzabal, and 
thence one day^s ride into the interior. 
62. Chlorostilbon osberti , 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 
ot 5000 feet above the sea-level—the highest altitude at which 
1 have yet observed it.
