64 MR. A. BOUCARD ON BIRDS FROM COSTA RICA. [Jan. 15, 



205. Myiobius sulphureipygius, Sclat. 

 Two specimens, from Naranjo, April. 



206. Myiobius erythrurus, Cab. 



One specimen, from San Carlos, February. 



This seems to be a rare species. I wanted more specimens, and 

 could only succeed in seeing anotber, which I could not shoot. 



207. Mitrephorus aurantiiventris, Lawr. 



Several specimens, from La Laguna, February Naranjo, April, 

 and Candelaria, May. I killed these in the forest at the altitude of 

 4000 to 8000 feet. * They used to stay at the same place for a long 

 time ; they select a branch, and you see them there all day long. 

 All the time they fly about catching insects, and returning to the 

 same spot. I missed one of my specimens twice ; notwithstanding, 

 it came back to its favourite branch. There is no appreciable 

 difference between the two sexes. I have also one specimen with 

 the abdomen of the same colour as the throat and the breast ; 

 otherwise there is no appreciable difference. It was obtained at 

 San Mateo, altitude 1000 feet. 



208. Empidonax flavescens, Lawr. 

 Several specimens, from Naranjo, April. 



209. Contopus virens, L. 



Several specimens, from Cartago, April. 



210. Myiarchus crinitus, L. 

 Native name " Traga mosca." 



Several specimens, from San Jose, January, and Cartago, April. 

 Rather rare in Costa Rica. They used to perch on a selected branch 

 of the trees edging the coffee-plantations, and remained there all day 

 long catching the insects passing by. 



211. Myiarchus panamensis, Lawr. 



Three specimens, from Punta Arenas, May. Killed on the mangle- 

 trees near the river. 



212. Myiarchus lawrencei, Giraud. 

 Myiarchus nigricapillus, Cab. 



Many specimens, from San Jose", Cartago, and Naranjo, January 

 to May. 



Native name " Tonto vivo." 



213. Myiarchus cinerascens, Lawr. 



Two specimens, from Punta Arenas, May. Killed at the end of 

 the sandy point near the town. 



214. Tyrannus melancholicus, Vieill. 



Many specimens, from San Jose, January to May. Common 

 everywhere, especially on the trees surrounding the coffee-plan- 

 tations.
