Colima and Puebla to eastern Oaxaca (Tehuantepec and Juchitan), 
México. 
Calocitia formosa azurea Nelson: 
Calocitta formosa azurea Neuson, Auk, 1897, p. 55 (Huehuetan, Chiapas, 
México). 
Darkest of all the races, being darker, brighter blue above, with the 
sides of the head white, except for the dark auricular spot. 
From extreme eastern Oaxaca (Tapandé) and Chiapas, across the 
Pacific slope of Guatemala. 
One bird from Tapana4 in eastern Oaxaca, near the border of Chiapas, 
is intermediate, having the side of the head as in azurea, but being only 
slightly darker above than formosa. 
Calocitta formosa 1mpudens van Rossem: 
Calocitta formosa impudens VAN RossEm, Proc. Biol. Soc. Washington, vol. 54, Dec. 
8, 1941, p. 172 (Pine Peaks, Voledn de Conchagua, El Salvador). 
Decidedly paler, grayer above, but brighter blue than formosa; the 
sides of the head white as in azurea, but decidedly lighter blue above. 
El Salvador, north into the arid valleys of the Caribbean slope in 
Guatemala. 
Calocitta formosa pompata Bangs: 
Calocitia formosa pompata Bangs, Proc. New England Zoél. Club, vol. 4, Mar. 13, 
1914, p. 102 (Bolsén, Guanacaste, Costa Rica). 
Somewhat darker above than impudens, but decidedly lighter than 
azurea, with the sides of the head as in the latter form. 
Western Nicaragua and Guanacaste, Costa Rica. 
A specimen from Chinandega in northwestern Nicaragua is some- 
what intermediate but is nearer pompata than impudens. I have not 
seen specimens from Honduras and am uncertain as to whether they 
are ampudens or pompata. 
Family TROGLODYTIDAE 
HELEODYTES RUFINUCHA CAPISTRATA (Lesson) 
Picolaptes capistrata Lesson, Rev. Zool., vol. 5, 1842, p. 174 (Realejo, Nicaragua). 
In the region about Liberia these wrens were common, this being 
one of the species that I encountered daily in the field. They range 
in small bands, sometimes near the ground in undergrowth, and 
again high in the trees. They are alert and active and ccme to at- 
tention through their movements and through their croaking calls. 
The nests are domed structures as large as a football, made of sticks, 
and placed near the end of a branch. Though this was not the nesting 
season they were adding sticks to them, so that I supposed they 
were using them as sleeping quarters. Inland I observed their nests
