tarsus, toes, and claws were black. The inside of the mouth and

 tarsus 31.0-34.2 (32.5) mm. 



Females (13 from Panama), wing 139.4-149.0 (144.4), tail 226-

from western Bocas del Toro east through the Chagres Valley and 

 San Bias to the Colombian boundary. 



There are no records to date for the whole of Chiriqui, or from 

 the Azuero Peninsula. It is probable that deforestation has re- 

 stricted its range on the Pacific side of Veraguas. Though Salvin 

 (Proc. Zool. Soc. London, 1867, p. 151; 1870, p. 201) recorded 

 specimens taken by Arce at Santiago, Calobre, and Santa Fe, in 

 1953 I found the species only near Sona, and there in small num- 

 bers. In western Code I recorded it on the higher slopes at El 

 Valle in 1951, and in the western sector of the Province of Panama 

 found a few on Cerro Campana, and one at Bejuco in the lowlands. 

 In eastern Panama Province it is found on Cerro Azul, and from 

 Chimin eastward through Darien it is more common, though mainly 

 in hill country. Here it has been recorded on Cerro Sapo, Cerro 

 Pirre (to 550 meters), and Cerro Tacarcuna (to 1,280 meters).
