NORTH AMERICAN EUCOSMINAE. 267 



Harpe of male genitalia of type figured. 



Alar expanse. — 23 mm. 



Type,— Cat No. 25618 U.S.N.M. 



Type locality. — Great Falls, Montana. 



Food plant. — Unknown. 



Described from unique type collected by Dr. H. G. Dyar, July 8, 

 1921. Closest to atomosana Walsingham. In the key would run to 

 atomosana and THonograminyMKi.^ but is easily separated from both 

 by the unmarked costa of its fore wing. 



EUCOSMA PALABUNDANA, new species. 



(Fig. 427.) 



Antennse dark fuscous, paler beneath. Palpus dark grayish fus- 

 cous; inner side paler, somewhat ochreous; terminal joint black. 

 Head dull sordid ochreous. Thorax blackish fuscous dusted with 

 white. Fore wing grayish white, marked and dusted with blackish 

 fuscous; an outwardly angulate blackish fuscous basal patch broken 

 near inner angle by whitish scaling; from middle of costa an out- 

 wardly slanting dark band which fuses with a similar dark outer 

 dorsal patch just before tornus, forming a complete angulate fascia; 

 costa beyond basal patch finely strigulated with white and blackish 

 fuscous; ocelloid patch consisting of two vertical pinkish bars in- 

 closing two or three narrow longitudinal black streaks, the outer 

 pinkish vertical bar broken below middle and bordered outw^ardly by 

 a blackish fuscous shade which curves inward over the ocellus; 

 cilia dark fuscous peppered with white and becoming paler at outer 

 margin. Hind wing dark smoky fuscous; cilia paler with a dark 

 basal band and the outer scales tipped with white. 



Harpe of male genitalia of type figured. 



Alar expanse. — 14-16.5 mm. 



Type. — In Canadian National Collection. 



Paratypes.—Q^X. No. 25619 U.S.N.M. 



Type locality. — Aweme, Manitoba. 



Food plant. — Unknown. 



Described from male type and one male paratype from Aweme, 

 Manitoba, dated, respectively, " 2-VII-1921," and " 25-VIII-1921," 

 Norman Criddle, collector, and one male paratvpe from Hessville, 

 Ind. (" A. K. Wyatt, VII-4-14 ") . 



A distinct species superficially most like Gypsonoma fasdolana 

 Clemens but easily separated from that species on structure. In the 

 key it would run down to rorana Kearfott, from which it is at once 

 distinguished by its very different harpes and the pinkish color of 

 the vertical bars of the ocelloid patch. In the arrangement given 

 it should be placed after grotiatia Kearfott.
