H. pimus. (Lat. pimus, a pine-tree.) BLuE-winGepD YELLOW WaRBLER. 4, adult: 
Fore part of crown and entire under parts rich yellow; upper parts yellow-olive, becoming 
slaty-blue on the wings and tail (system of coloration thus like that of Protonotaria). Wings 
with two white or yellowish bars; tail with several large white blotches; under tail-coverts 
white; eyelids bright yellow; small stripe through eye black ; bill blue-black. Female and 
young not very dissimilar; duller and more olivaceous. Length about 4.75; extent 7.50; 
wing 2.40-2.50; tail 2.00-2.10; tarsus 0.65; bill 0.45. Eastern United States, north to 
Massachusetts and Minnesota, west to Kansas, Indian Territory, and Texas; common, migra- 
tory, breeding in its United States range, wintering extralimital. Nest on the ground, eggs 
4-5, 0.67 x 0.48, white, sprinkled with reddish-brown dots. : 
H. lawren/cii? (To Geo. N. Lawrence, of N. Y.) Lawrencr’s WARBLER. Like H. 
pinus ; but a large black patch on the throat and breast, and broad black eye-stripe, reaching’ 
over auriculars, as in H. chrysoptera ; thus pinus X chrysoptera, and doubtless a hybrid 
between the two. New Jersey; two specimens noted to date. 
H. leucobronchia'lis? (Gr. Aevxds, leucos, white, Bpdyxos, brogchos, becoming bronchus, 
throat.) WHITE-THROATED WARBLER. Like H. chrysoptera ; but a black bar through the 
eye as in pinus, and lacking the black breast-patch of chrysoptera, the entire under parts being 
white; thus chrysoptera X pinus, and doubtless a hybrid between the two, though up to date a 
dozen or more specimens have been described, from New England, New York, Pennsylvania, 
and Michigan. 
H. cincinnatien’sis? (Of Cincinnati, Ohio, where discovered.) CINCINNATI WARBLER. 
Like H. pinus in color; bill with evident rictal bristles; no white wing-bars or tail-blotches ; 
no ashy-blue on wings or tail; concealed black on crown and sides of head like the incom- 
pleted black mask of Oporornis formosa, with which the bird otherwise closely agrees in color ; 
thus curiously being H. pinus X O. formosa. Length 4.75; wing 2.50; tail 1.85; bill 0.44. 
One specimen known, Ohio.
