Hab. Norru America, Rio Grande valley—Mexico, Nuevo Leon (Couch ?). 
This species was first described as long ago as 1851 by Mr. Lawrence from specimens 
obtained by Capt. J. F. M‘Cown in the valley of the Rio Grande. Subsequent obser- 
vations tend to show that its range is nearly restricted to that district. It has been 
stated to extend to Southern Mexico; but Mr. Ridgway has shown that the bird from 
that region is separable by fairly pronounced characters, though his giving it a third 
name indicates that he expects intermediate forms to be extant connecting the two. 
Mr. Sennett and Dr. Merrill had abundant opportunity of observing EL. rufivirgata in 
the valley of the Lower Rio Grande at Lomita and elsewhere. They found a number 
of its nests and eggs; the former are domed, and often placed in the heart of a bush 
from two to five feet from the ground; the nest is nearly round, and made of dried 
stems of weeds, pieces of bark, grasses, and leaves, sometimes with a little hair for 
lining, but more frequently without. The eggs, four in number, are of a pure dull 
white colour.

Hab. Mexico, Cordova (Sallé*), temperate and hot regions of Vera Cruz (Sumichrast *), 
Playa Vicente (Boucard °). 
The Embernagra of Southern Mexico differs from EF. rufivirgata in having a much 
stouter bill, the flanks deep drab or raw-umber. brown, and the crissum deep fulvous }. 
The bird is altogether of a stouter build. 
Sumichrast states that this species inhabits the hot and temperate regions, and is 
found in the latter as high as 4000 feet above the sea 4.
