 about one-third of the wing. Lobes of hind wing very light buff, with a 

 silky lustre ; fringes darker. The under side of all wings decidedly 

 lighter than upper side, with a less silky appearance, a duller lustre, but

Habitat : Santa Ana River, 5,500 ft, altitude, San Bernardino Mts , 

 Calif. (J. Grinnell), Aug. 4, 8, 1907. There is a single specimen from the

My six specimens are all constant, and I think the differences warrant
