27, 1908, pp. 413-414). Winters irregularly, "south of the Saskatchewan and 

 east of the Rocky Mountains", south to Kentucky, Pennsylvania, etc. (A. O. U. 

 Check-list, 1910, p. 241). 



Hesperiphona vespertina brooksi*, new subspecies 

 British Columbia Evening Grosbeak 



Type. — Male; no. 24517, Mus. Vert. Zool. ; Okanagan, British Columbia; No- 

 vember 13, 1913 ; collected by Allan Brooks. 



Diagnosis. — Bill thick as in vespertina, but longer and hence relatively 

 slenderer; slightly less slender on an average than in calif ornica and ivarreni, 

 but decidedly thicker than in montana. Color-tone of body of male decidedly the 

 darkest as compared with all the other subspecies; as a result, line of demarca- 

 tion between black cap and hind neck not sharply defined. Frontal yellow bar 

 of male averaging much broader than in any other subspecies except warreni and 

 vespertina, and but slightly narrower than in the latter form. Color-tone of body 

 of female darker than in any other subspecies ; more sooty on top of head and 

 back, and darker brown beneath ; decidedly less ashy about head and on lower 

 surface than in vespertina, most nearly as in calif ornica. 



Summer range. — Not known, but probably west of the Rocky Mountain di- 

 vide, in British Columbia, Canada. The series at hand was taken on various win- 

 ter dates at Okanagan and Chilliwick, B. C, and Tacoma, Washington. 



Hesperiphona vespertina californica, new subspecies 

 California Evening Grosbeak 



Type.— Male ; no. 25638, Mus. Vert. Zool. ; Crane Flat, 6300 feet altitude, 

 Mariposa County, California; June 15, 1915; collected by Tracy I. Storer; orig. 

 no. 1257. 



Diagnosis. — Bill of intermediate degree of relative thickness, more nearly as 

 in brooksi and ivarreni; distinctly thicker than in montana. Color-tone of body 

 of male intermediate in depth, much as in vespertina though averaging yellower 

 beneath ; in latter respect approaching montana. Frontal yellow bar of male rel- 

 atively narrow, much narrower than in vespertina, ivarreni and brooksi. Col- 

 or-tone of body of female light brownish gray, more brown than in vespertina, 

 less blackish on crown and back than in brooksi; near montana, but not quite so 

 yellowish brown beneath ; somewhat darker than in warreni. 



Summer range. — Chiefly in Sierra Nevada of California, south at least to 

 Yosemite National Park ; but also Warner Mountains, Modoc County, and thence 

 north at least to Bear Creek, Wheeler County, Oregon (see L. H. Miller, Condor, 

 vi, 1904, p. 104). Winters irregularly in adjacent territory south to Mount Wil- 

 son, Los Angeles County, California. 



Hesperiphona vespertina montana Ridgway 

 Mexican Evening Grosbeak 



Type.— No. 35150, U. S. Nat. Mus. ; from [Mirador, near Vera Cruz], "Mex- 

 ico" (Ridgway, 1874, p. 449 and fig. 4 on pi. 22) ; male, orig. no. 180; collected 

 by Dr. C. Sartorius ; June, 1864. 



Synonym. — Coccothraustes vespertinus mexicanus Chapman (1897, p. 311) ; 

 type from Las Vigas, Vera Cruz, Mexico. 



Diagnosis. — Bill much slenderer than in any of the other forms, with decided 

 curvature downward, involving especially the gonys and commissure ; the anti- 

 thesis of the condition in vespertina. Color-tone of body of male light, averaging 



♦Named in recognition of Allan Brooks's contributions to northwestern ornithology.
