greater wing-coverts extending back nearly to the tips of the overlapping 
middle coverts and forming an almost confluent wing-patch; white on the 
tail about twice as extensive as in americana, edging the outer web of the 
outer feather from the base nearly to the tip, occupying the inner web of 
this feather to the shaft for a space half an inch in length, and the inner web 
of the next feather for a space one quarter of an inch in length; sides of 
head as in C. nzgrilora, the eyelids and lores equally black, ‘‘this color 
extending asa narrow, frontal line to meet its fellow across base of cul- 
men, and also reaching back to invade the auriculars on which it shades 
through dusky to the general bluish’; under wing and tail coverts, 
crissum, and extreme posterior part of abdomen,.and flanks, white, re- 
mainder of under parts rich chrome yellow, tinged with brownish orange 
on the throat, jugulum, breast, sides, and fore part of the flanks; throat 
and jugulum bordered on each side by a white line, broadest at its poste- 
rior extremity, narrowing to nothing on the sides of the throat. Wing, 
2.30; tail, 1.75; culmen from nostril, .29 inch. 
Q ad. ‘No. 14,380, collection of W. Brewster, Hacienda de San Rafael. 
Chihuahua, Mexico, May 14, 1888; M. Abbott Frazar).° Similar to the 
male, but smaller; the general coloring paler; the lores slaty, not black, 
the throat scarcely tinged with orange, the wing-bands narrower and not 
merged. Wing, 2.10; tail, 1.61; culmen from nostril, .29 inch. 
This beautiful Warbler, of which Mr. Frazar has sent me no 
less than thirty-two specimens, all taken at the same place and 
season as the types above described, is evidently most nearly re- 
lated to C. xigrzlora, with which it agrees perfectly in respect to 
the black lores and eyelids and the slaty auriculars. In at least 
two respects, however, — the extent of the white spots on the 
tail and the decided brownish orange tinge of the throat, breast, 
and sides—it presents a curious approach to americana, but the 
white on the tail is even more extended than in amerzcana, while 
the orange beneath is considerably paler. Its only point of marked 
resemblance to its nearest geographical allies, ¢zsa/ar¢s and gray- 
sont, is the extension of the yellow of the under parts over most of 
the abdomen. ‘There is some variation in this respect, however, 
as well as in the amount of white on the wings. In fact only a 
few specimens have the wing-bars actually fused as in the type of 
the male. The white line bordering the sides of the throat and 
jugulum is evidently inconstant also, for it is found in only three 
or four of my specimens.
