EMBERNAGRA. 
Embernagra, Lesson, Traité d’Orn. p. 465 (1831). | 
We are acquainted with eleven species of this genus, of which all but two are 
concentrated in Mexico, Central America, and the north-western portion of South 
America. The genus is unrepresented in Guiana, the basin of the Amazons, and Eastern 
Brazil; but two species, including the type of the genus, occur in the Argentine 
Republic, Bolivia, and Patagonia. These latter differ rather widely from their more 
northern congeners, and may readily be distinguished by their larger size, more elongated 
form, and by the absence of markings on the upper part of the head. 
T'wo Mexican species pass beyond the northern frontier, but the other five species of 
our fauna do not range beyond its limits, though we find two species, E. conirostris and 
L. chrysoma, both nearly related to Z. striaticeps, in Colombia and Ecuador respectively. 
LEmbernagra striaticeps has the general upper plumage of an olivaceous colour, and 
this character pervades all the members of the genus; the head is marked by stripes on 
either side of the vertex and others through each eye: Z. chlorura and the southern 
species HL. platensis and E. olivascens depart from the rest in this respect, E. chlorura 
standing alone in having a russet crown; the under plumage of all is white, with 
grey chest and flanks, the latter usually tinged with olivaceous. ‘The wings are short 
and rounded, the primaries but little shorter than the longest secondaries ; the third, 
fourth, and fifth quills are the longest in the wing, the second equalling the eighth, 
the first being shorter than any of the rest; the bill is moderately stout, and the tomia 
of the maxilla but slightly angulated; beneath the exposed nostril the bill is somewhat 
tumid ; the rictal bristles are short but strong ; the legs are strong, being suitable for birds 
of terrestrial habits ; the middle toe and claw are a little longer than the tarsus. 
Lmbernagra seems allied to Pipilo, but its less elongated form and very different 
coloration seem to justify its separation.
