Jan.,1917 'FILE SUBSPECIES OF HESPERIPHONA VESPERTIArA

21 more yellowish even than in californica. Yellow frontal bar of male very nar- row, averaging narrower than in any other form. Color-tone of body of female browner than in any other form, sharply different from the gray east in vesper- tina and the sooty tone above in brooksi; paler in tone of brown beneath than in califordca, most nearly as in warrenS. Summer range.--Specimens at hand only from the following places, all prob- ably breeding localities: Mirador and Las Vigas, both not far from Vera Cruz, Mexico; Huachuca and Chirlcahua mountains, Arizona. I am unable to distin- guish the birds of extreme southern Arizona from the Vera Cruz birds. Hesperiphona vespertina warreni*, new subspecies Rocky Mountain Evening Grosbeak Type. Male; no. 1399, Colorado College Mus.; Bear Creek, near Colorado Springs, Colorado; June 19, 1898; C. E. Aiken. Diagnosis.--Bill of moderate degree of thickness, seemingly identical in this respect with californica; therefore mudh thicker than in montana, and yet unmis- takably slenderer than in vespertiaa. Color-tone of body of male averaging the same as in californica. Frontal yellow bar of male broad, very nearly as broad as in vespertina, therefore decidedly broader than in californica. Color-tone of body of female averaging nearest montana, slightly paler perhaps, therefore not- ably different from the usual case in vespertina; slightly paler about the head than in californica, and decidedly paler than in brooksi. Summer rage.--Southern Rocky Mountain region, at least in Colorado, New Mexico and north-central Arizona. Specimens in the American Museum of Natural History taken by Mearns in the vicinity of Fort Verde, Arizona, belong here, and not to the form represented in the Chiricahua and Iluachuca moun- tains, in the same state, these latter being unequivocally montana as here under- stood.

A "type" is for the first time specifically mentioned as such and is stated to have come from Cantonment Burgwin, New Mexico.
