Habitat. — California, Arizona, Nevada. 



This species has a certain false air of the cupida group that misled 

 Mr. Grote in his description of the species and in his subsequent arauge- 

 ments and lists. 



Two 9 specimens from Arizona agree with typical California speci- 

 mens in structure and in detail of maculatiou, but the color is much 

 more even, shot with reddish, and the primaries have the outer margin 

 evidently more oblique. Possibly with a larger material this form may 



prove distinct.
