white, somewhat dusted with pale brown on anterior margin. Fore 

 wing white, finely cross-lined with pale leaden gray and ocherous, 

 giving the w4ng a grayish white color; an angulate dark basal patch 

 very faintly indicated; a similar obscure patch on dorsum before 

 tornus connecting with an even fainter marking from just beyond 

 middle of costa and with it forming an almost obsolete angulate 

 fascia; ocelloid patch an obscure white patch inwardly margined by 

 a few black scales; above ocelloid patch a scattering of black scales; 

 occasionally a few black scales on middle of cell at base and at outer 

 angle of the basal patch; costal striations narrow, faint, continuous 

 from base to apex; cilia white, with a broad basal peppering of black 

 scales and a fuscous and black shading at apex; veins 3, 4, and 5 not 

 approximate at termen; termen concave. Hind wing smoky fuscous; 

 cilia white with a dark basal band. 



Male genitalia figured from type. 



Alar expanse. — 22-25 mm. 



Type. — In collection Barnes. 



Paratype. — Cat. No. 41204, U.S.N.M., also in American Museum 

 and collection Barnes. 



Type locality. — Mohave County, Ariz, 



Food plant. — Unknown. 



Described from male type and three female paratypes, all from the 

 type locality ("Aug. 24-31")- I have also before me a female from 

 San Diego, Calif., and a somewhat smaller male from Paradise, Cochise 

 County, Ariz., which are presumably the same or varieties of the 

 same species.

 Figure 14 



An ashy white species with an oblique dark dash above dorsum 

 beyond base and a dark triangular patch on dorsum near tornus. 



Palpus, face, head, and thorax ashy white (the scales pale fuscous 

 tipped with white), somewhat darker on outer side of palpus. Fore 

 wing white, somewhat dusted with pale fuscous, making the ground 

 color an ashy white, and with blackish fuscous maculations; beyond 

 base above dorsum an oblique dark dash; on dorsum before tornus a 

 prominent triangular dark patch; on costa beyond area of fold sev- 

 eral narrow dark dashes interspaced with white lines; a conspicuous 

 dark spot at apex, and bordering outer margin of ocelloid patch and 

 curving above it a thin dark line; the costal maculations and apical 

 spot faintly repeated on undersurface; ocelloid patch consisting of 

 two broad, obscure, sordid white bars inclosing a black dot near their 

 upper margins; cilia white dusted with blackish fuscous and with a 

 dark basal line; veins 3, 4, and 5 somewhat approximate at termen; 

 termen slightly concave. Hind wing pale ocherous fuscous; cilia 

 white with a broad dark basal band and a dark outer shading.
