Habitat. — Sierra Nevada, California ; Placer County, California. 



In the Museum collection are three female specimens marked June, 

 Placer County, California (through C. V. li), red number 308. 



From Mr. Edwards I have specimens marked Sierra Nevada, also all 

 females. 



The species has somewhat the habitus of hibens, and much of its gen- 

 eral style of maculation. The distinct white s. t. line with the promi- 

 nent W-mark affords an easy distinctive character.
