VIREONIDZA: VIREOS, OR GREENLETS. 335 
entirely yellowish. California. First quill rather less than half the 2d, which about equals 
the 10th; 3d a little longer than 7th; 4th and 5th nearly equal and longest. Tail slightly 
rounded, shorter than the wings. Bill very small. Above olive-green; brightest behind, 
especially on rump and edging of tail; duller and more 
ashy toward and on top and sides of head and neck, ===——_— 
Wings with two bands on coverts, and outer edges of = 3 
innermost secondaries rather broadly olivaceous-white ; EN 
other quills edged externally with olive-green, paler | A 
toward outer primary, internally with whitish. Lat- wm, is 
eral tail-feathers edged externally with yellowish- \” ph leads exe 
white. Feathers of rump with much concealed yel- 
lowish-gray. Under parts pale olivaceous-yellowish, 
purest behind, lightest on throat and abdomen; the breast more olivaceous, the sides still 
deeper olive-green, the breast soiled with a slight buffy tinge. Avxillars and crissum yellowish, 
the inside of wings whitish. Loral region and narrow space around eye dull yellowish, in faint 
contrast to the olive of head. Bill horn-color above, paler below; legs dusky. Length 4.70: 
wing 2.40; tail 2.05. (Description from Baird.) 
V. h. ste/vensi. (To F. Stephens.) STEPHENS’ GREENLET. Like V. huttoni. Bill stout ; 
wings from 0.30-0.40 longer than tail. Above, grayish-ash ; the crown, vertex and sides of 
head and neck nearly pure ash; the back faintly tinged with olive; the rump and an edging on 
the tail-feathers dull olive-green. Wings with two nearly confluent bands on the coverts, and 
the outer edges of the imner secondaries broadly white ; outer quills edged more narrowly with 
the same color. Beneath brownish or smoky-white, with a mere wash of yellowish on the sides 
and crissum. Upper eyelid dusky-brown; remainder of the orbital region, with the lores, 
ashy-white in decided contrast with the nearly clear cinereous of the head generally. Lining 
of wings white. Length 5.20; extent 8.50; wing 2.55-2.90; tail 2.25; tarsus 0.73; culmen 
0.50. Arizona and New Mexico, especially in mountain ranges. Related to huttoni, which 
has bill less stout, wing 2.40 or less, and is olive-green above and olivaceous-yellow below, 
without clear white anywhere. The differences are nearly parallel with those between belli and 
pusillus, —stevensi being grayish-ash above with no decided olive-green excepting on the rump 
and tail, brownish-white below, untinged with yellowish excepting on sides and crissum, the 
wing-bands pure white and nearly confluent. (Not in Check List, 1880. Description from 
Brewster, Bull. Nutt. Club, vii, 1852, p. —.) 
V. belli. (To J. G. Bell, of New York. Fig. 200.) BrELL’s GREENLET. Olive-green, 
brighter on rump, ashier on head, but without decided contrasts; head-markings almost 
exactly as in gilvus; below, sulphury-yellowish, only whitish on chin and middle of belly ; 
inner quills edged with whitish; two 
whitish wing-bands, but one more con- 
spicuous than the other. Hardly or not 
5.00 long; wing scarcely over 2.00; tail 
under 2.00; spurious quill about 2 the 2d, 
which equals or exceeds the 7th. A pretty 
little species, like a miniature of gilvus, but 
readily distinguished from that species by 
its small size, presence of decided wing-bars, more yellowish under-parts, and different wing- 
formula. Middle region of the U. 8., W. to the Rocky Mts., E. to the valley of the Ohio; an 
abundant species, inhabiting copses and shrubbery in open country, with much the same 
sprightly ways and loud song as those of noveboracensis. 
V. pusil/lus. (Lat. pusillus, puerile, petty. Fig. 201.) Least GREENLET. Olivaceous- 
gray, below white, merely tinged with yellowish on the sides; head-markings obscure ; wing~
