GENUS CHRYSOMITRIS, BOIE.

_Chrysomitris_, BOIE, Isis, 1828, 322. (Type, _Fringilla spinus_,

LINN.)

_Astragalinus_, CAB. Mus. Hein. 1851, 159. (Type, _Fringilla

tristis_, LINN.)

_Hypacanthus_, CAB. Mus. Hein. 1851, 161. (Type, _Carduelis

spinoides_.)

[Line drawing: _Chrysomitris tristis._

1521 ♀]

GEN. CHAR. Bill rather acutely conic, the tip not very sharp; the

culmen slightly convex at the tip; the commissure gently curved.

Nostrils concealed. Obsolete ridges on the upper mandible. Tarsi

shorter than the middle toe; outer toe rather the longer, reaching to

the base of the middle one. Claw of hind toe shorter than the digital

portion. Wings and tail as in _Ægiothus_.

The colors are generally yellow, with black on the crown, throat,

back, wings, and tail, varied sometimes with white.

The females want the bright markings of the male.

This genus differs from _Ægiothus_ in a less acute and more curved

bill, a much less development of the bristly feathers at the base of

the bill, the claw of the hind toe shorter than its digital portion,

the claws shorter and less curved and attenuated, and the outer

lateral toes not extending beyond the base of the middle claw.

The species exhibit many differences among themselves, especially in

the size and shape of the bill, which have been made the basis of

generic distinctions. They may be distinguished as follows:—

Species and Varieties.

A. No streaks anywhere on plumage; base of tail-feathers black

or white. Sexes dissimilar. (_Chrysomitris._)

_a._ No yellow on the wings.

1. C. tristis. Inner webs of tail-feathers always whitish

terminally (except in _Juv._). ♂. Forehead and crown, wings

and tail, deep black; rest of plumage, including the back,

rich lemon-yellow; tail-coverts white. ♀. Body grayish above,

dingy whitish beneath, stained with yellow; no black on head;

wings and tail duller black. _Juv._ Fulvous-umber above, with

markings of reddish-ochraceous on the wings; beneath,

dilute-yellow washed with fulvous. _Hab._ Whole of temperate

and warm North America.

2. C. psaltria. Inner webs of tail-feathers never whitish

terminally. ♂. Beneath yellow, including the lower

tail-coverts; above black, with or without olive-green on the

back. ♀. Without any black, the yellow duller.

_Tail with white on inner webs; tertials with large white spots._

♂. Auriculars, nape, back, and rump olive-green. _Hab._

Rocky Mountains of United States … var. _psaltria_.

♂. Auriculars black; nape, back, and rump green clouded

with black. _Hab._ Arizona … var. _arizonæ_.

♂. Auriculars, nape, back, and rump entirely black. _Hab._

Middle America … var. _mexicana_.

_Tail without any white on inner webs; tertials without white

spots._

♂. Auriculars, nape, back, and rump wholly black. _Hab._

Panama and New Granada … var. _columbiana_.

_b._ Terminal half of outer webs of wing-coverts and

secondaries yellow.

3. C. lawrencii. Prevailing color ashy, lighter beneath. ♂.

A large patch on the breast, the rump, and most of the outer

surface of the wing, yellow; forehead, crown, lores, all

round base of bill, chin, wings (beneath the yellow), and

tail black. ♀. Lacking the black, and with the yellow only

indicated. _Hab._ California and Southwestern Arizona.

B. Whole body and head thickly streaked; bases of tail-feathers

yellow. Sexes alike. (_Astragalinus._)

4. C. pinus. Above brownish-gray, beneath white, with

conspicuous dusky streaks everywhere; two light bands on the

wing; bases of secondaries and primaries yellow. _Hab._ Whole

of North America.

Three species of _Chrysomitris_, given by Mr. Audubon, are to be

erased from the list: _C. stanleyi_, _C. yarrelli_, and _C.

magellanica_. If, as he states, he killed specimens of the latter in

Kentucky, they must have belonged to the _C. notata_ of Dubus, a

Mexican species, not since met with in our limits. The other two were

given him as coming from California,—a statement we now know to be

incorrect, both belonging to South America.
