289. Thryophilus modestus (Cabanis). 



This species was more 'common on the Pacific side, near the coast, 

 than in the interior. Ten specimens were collected,-- Gualan, Lake 

 Atitlan, Lake Amatitlan, Patulul and San Jose" being the localities. 

 These specimens show decided individual variation as to color and 

 distinctness of barring on the tail. The wings and the tails of this 

 series average slightly less than those of Costa Rican specimens. As 

 to color, in this series of ten there are specimens that are lighter than 

 the three adult examples from Costa Rica in this Museum, and others 

 that are darker; while some have the dark tail-bars more distinct, 

 and some less distinct than those from Costa Rica. Iris dark brown.

Two were secured at'Mazatenango, the only locality where any
