NORTH AMERICAN EUCOSMINAE. 133 



Alar expaTise, — 15-20 mm. 

 Type. — In American Museum. 

 Type locality. — Stockton, Utah. 

 Food plant. — Unknown. 



120. EUCOSMA METARIANA, new species. 

 (Fig. 251.) 



Like r or ana Kearfott, but with head whitish and without yellowish 

 cast on fore wing. Ground color of fore wing white; fuscous 

 markings more decidedly brown; two distinct dorsal spots as in 

 rorana and expolitana; outer dorsal spot margined by whitish scal- 

 ing above; no post median fascia as in rorana; white ground color 

 obvious, but much lined with fuscous. 



Male genitalia of type figured. 



Alar expanse. — 12-16 mm. 



Type. — ^In collection Barnes. 



Pavatypes.- — Cat. No. 24819 U.S.N.M. ; also in American Museum 

 and collection Barnes. 



Type locality. — Shasta Eetreat, Siskiyou County, California. 



Food plant. — Unknown. 



Described from male type and five male paratypes from Shasta Re- 

 treat, Siskiyou County, California ("June 16-23," "June 24-30") ; 

 two male paratypes from Hot Springs, Green Eiver, Washington, and 

 one male paratype from Victoria, British Columbia (E. H. Black- 

 more, " 19-VII-20 "). 



In pattern and color metariana falls between rorana Kearfott and 

 passerana Walsingham. In genitalia these three species as well as 

 expolitana.^ zomonana, and vandana are almost identical. I have de- 

 scribed it as a species but strongly suspect that it and rorana are only 

 local races of passerana.
