720 Annals of the Carnegie Museum. 



Bangs Collection: San Jose, Bolson, Carrillo, Buenos Aires, and El General 



de Terraba (Underwood). 

 Carnegie Museum: Guaitil, Tierra Blanca, Miravalles, Boruca, Buenos 



Aires (Carriker). Nine skins. 



This species of Elcenia occupies the central plateau and the Pacific slope 

 down to about 1,000 feet above sea-level, and is rarely taken as a straggler 

 on the Caribbean watershed (Carrillo). It keeps entirely in the open, 

 never being taken in the forest. It is fond of trees along roadsides, 

 streams, and in scattering woodland. It is quite common in the hills about 

 Boruca around the edges of the "sabanas." 



I took a nest with two fresh eggs at Guaitil, May 3, 1902, which was 

 exactly like those described by Mr. Cherrie (Auk, VII, 1890, 235), much 

 resembling the nest of the common Wood Pewee (Myiochanes virens). 

 It was a well-built, cup-shaped structure, made of roots and weed-stems, 

 covered over on the outside with lichens, and placed in an upright 

 crotch about twelve feet above the ground. The eggs are creamy-white, 

 with a slightly rosy tinge, having a few markings of lilac, and a wreath of 

 chestnut dots around the larger end. Measurements: 21. 5X16 and 22 X 



16 mm. 



487. Sublegatus arenarum (Salvin).

Elainea arenarum Lawrence, Ann. Lye. N. Y., IX, 1868, 112 (Puntarenas 

 [Salvin and Dow]). — Frantzius, Jour, fur Orn., 1869, 307 (Costa Rica). —

Sublegatus arenarum Salvin and Godman, Biol. Centr.-Am., Aves, II, 1888, 

 37, part (Puntarenas). — Ridgway, Birds N. and Mid. Amer., IV, 1907, 420 

 (Puntarenas). 



This bird, if really distinct from the Panaman species, S. glaber, is known 

 only from the type specimen collected at Puntarenas by O. Salvin and 

 Capt. J. M. Dow in 1863. Every Costa Rican collector has hunted assid- 

 uously for it, but with no success, and the bird still remains one of the 

 many unsolved ornithological mysteries. 



488. Camptostoma imberbe Sclater. 



Camptostoma imberbe Sclater, P. Z. S., 1857, 203 (San Andreas, Vera Cruz,

 Nicaragua). — Bangs, Proc. Biol. Soc. Wash., XXII, 1909, 33 (Tenorio,
