fore it reaches the costa and separated from the outer margin by ^n equal space of the 

 ground color. On the hind wings there is a similar disposition of markings, except 

 that the bright red band is broader and is separated from the outer margin by a nar- 

 rower area of the ground color ; two black dots in the angle more or less invade the 

 red ; this band does not quite reach the costa or inner margin. Undersides in color 

 grayish brown ; spots very pronounced and more or less transversely elongated ; two 

 heavy round spots between discal point and base ; the arrangement is otherwise the 

 same as in the male. Body grayish- brown inclining to blackish. Fringes grayish 

 brown. 



This species is readily distinguishable from Cupido dcedalus Behr 

 and other described forms by the bright red bands of the upper sides 

 (in the $ ) which make a decided contrast with the ground color. In 

 an occasional specimen the ground of forewings is reddish and so 

 tends to obliterate the red band ; but in our considerable series this is 

 an exception. The heavy spots of both sexes are also characteristic, 

 as is also the deep brown, inclining to reddish, of the females. 



This is the same thing that is figured in Wright's " Butterflies of 

 the West Coast " as dcBdalus, but Jiilda is easily separable from dcedalus 

 by the characters just indicated. The two specimens figured by 

 Wright seem to be extremes oV else the color-photography has not 

 succeeded in showing well the contrast between ground color and 

 band. 



The group to which Cupido hi/da belongs is subject to great vari- 

 ation geographically, and has been neglected unduly. Large series of 

 specimens from all over the country will be required for a proper study 

 of the group. 



Types of the new species above described are retained in the 

 Grinnell collection. Topotypes will be deposited in the U. S. Na- 

 tional Museum. The type-locality is the upper cienega at the head 

 of the South Fork of the Santa Ana, at an elevation of about 8,500 

 feet (according to the San Gorgonio Quadrangle Topographic Sheet, 

 U. S. G. S.). Here the species was numerous the last of June over 

 the cold Canadian meadows, appearing in the forenoons after the sun- 

 shine had dispelled the frost. Although taken at lower elevations, the 

 species was nowhere else so well represented. Our series includes the 

 following examples : Cienega at head of South Fork of Santa Ana, 

 8,500 feet, June 27 and 28, 1905, 7 cfcJ', 29 $ ? ; South Fork, 6,200 

 feet, June 28-July 7, 1906, 12 cJ^cf, 5$? ; Fish Creek, 6,500 feet, 

 June 22, 1905, 3 c?d^, 1 9 ; Santa Ana, 5,800 feet, July 20, 1906, i 9.
