Show 1878.] MR. A. BOUCARD ON BIRDS FROM COSTA RICA. 69 237. OREOPYRA CALOLAMA, Salv. Many specimens of both sexes from Naranjo, April; Navarro and Rancho redondo, May. I have not the least doubt that the bird described as Anthocephala castaneiventris, Gould, is the female of this species. These birds are only met with in the forest. 238. OREOPYRA HEMILEUCA, Salv. Two specimens, from Naranjo, April. It seems to be a very rare species. 239. PETASOPHORA CYANOTIS, Bourc. Petasophora cabanisi, Lawr. Several specimens from the Volcano of Irazu, April. Rather common at the altitude of 8000 feet, feeding on the flowers of a small shrub. They take possession of a certain space containing several of these shrubs; aud when not feeding on these flowers, they perch on a dry branch near the place, and fight all the other Humming-birds that dare to intrude. 240. HELIODOXA JACULA, Gould. Heliodoxa henryi, Lawr. Several specimens from Naranjo, April; Volcano of Irazu, May. One male, although it is not in very fine plumage, has a bright front, and the throat exactly like the specimens from Columbia. Rather rare in Costa Rica. 241. HELIOMASTER CONSTANTI, Delattre. Only one young male, from San Jose, January ; killed while he was sucking the flower of an acacia tree. 242. THALURANIA COLOMBICA, Bourc. & Muls., var. VENUSTA, Gould. Several specimens from San Carlos, February; and Naranjo. April. It perches on very high trees in the forests, and is difficult to get at. It is a rare species in Costa Rica. I spent many hours before I could get the pair which I have, from San Carlos. I could not recognize the bird, because it was standing and feeding on the flowers of a parasitic plant very high on a large cedar tree. I thought it was a new species of Microchera, so small was its appearance. When I killed the first I was quite disappointed, and was sorry to have lost so much time for it. 243. KLAIS GUIMETI, Bourc. & Muls. Klais merriti, Lawr. Only two specimens, from Navarro, M a y : a very rare species. 244. MICROCHERA PARVIROSTRIS, Lawr. Only one specimen of a young male, given to m e by Mr. Juan Zeledon. Excessively rare. Although I knew the exact locality where found, I could never find one. |
