 patch and outer fascia. 



Palpus, face, head, and thorax white. Fore wing white with dark 

 markings pale ocherous-fuscous ; an outwardly angulate basal patch 

 not reaching costa and broken longitudinally by streaks of the white 

 ground color ; costa from base to middle pure white, unmarked ; from 

 just beyond middle a dark band slanting outward to upper inner edge 

 of ocelloid patch and joining a vertical shade of the same color from 

 tornus, forming with it a complete angulate fascia; on outer half of 

 costa three conspicuous dark spots; ocelloid patch white containing 

 two black streaks and shaded above by ocherous-fuscous; cilia white 

 heavily peppered with fuscous and blackish scales. Hind wing very

Male genitalia as in striatana occidcntdlis. 



Alar expmise. — 17 to 20 mm. 



Type and paratypes. — U.S.N.M. No. 43256; paratypes in Clarke, 

 American Museum, and Canadian national collections. 



Type locality. — Rochester, Wash. 



Food plant. — Unknown. 



Remarks. — Described from male type, seven male paratypes from 

 the type locality (" 13-VI-29 " and " 26-VI-29," W. W. Baker), 

 and one male paratype from Wellington, British Columbia (Theo. 

 Bryant, collector, " Blackmore No. 890), all received from John 

 F. Clarke. 



This species is close to and possibly another extreme variety of 

 striatana Clemens but differs so markedly from it and its other 

 western variety {occidentaJis) in pattern that I hesitate to name it 

 anything but a distinct species. 



GRETCHENA DULCIANA Heinrich 



The food plant of this species is alder {Alnus). The larvae tie 

 the tender terminal leaves in a small compact bundle and feed within
