NORTH AMERICAN EUCOSMINAE. 131 



fuscous, but the white ground color nowise obscured thereby ; ocellus 

 only faintly marked with scattered fuscous or blackish scales; cilia 

 fuscous, the tips of the scales white; hind wing smoky fuscous; 

 cilia pale fuscous, with a darker basal line and the tips of the scales 

 white. Fore and middle legs fuscous with scaling at ends of joints 

 whitish; hind legs dirty white not appreciably banded or shaded 

 with fuscous. 



Male genitalia of type figured. 



AlcM' expanse. — 18-22 mm. 



Type.— Ciit. No. 24817, U.S.N.M. 



Paratypes. — In National Collection, American Museum, and col- 

 lection Barnes. 



Type locality. — Vineyard, Utah. 



Food plant. — Unknown. 



Described from male type and two male and four female para- 

 types all from Vineyard, Utah, Tom Spalding, collector (one speci- 

 men dated "VII-6-12"; two dated "VII-8-12"; three, "VII- 

 10-12"; and one, " VII-14r-12"). Part of these were from the 

 unplaced material in the National Museum and the rest from Doctor 

 Barnes' collection. 



I have described this species with considerable hesitation and 

 some doubt. It may prove to be a local race of palousana Kearfott. 

 All the specimens of palousana I have seen are old and more ochre- 

 ous than fuscous colored in the dark areas. The whitish parts of 

 fore wing also have a yellowish tint entirely lacking in suadana. 

 The white head and the dark fuscous rather than ferruginous spots 

 on fore wing exclude suadana from hiquadrana Walsingham which 

 it also approaches closely.

There is a female paratype in the National Collection. I have 

 seen no other specimens. It is distinguished from the other species 

 in this immediate group by the pure white cilia of the fore wing. 

 Walsingham described it from California, but also records a speci- 

 men from Arizona.^^
