115. EUCOSMA PALOUSANA Kearfott. 



(Fig. 222.) 



En-cosma palousana Kearfott, Trans. Amer. Ent. Soc, vol. 33, 1907, p. 34;— 

 Barnes and McDunnough, Check List Lepid. Bor. Amer., no. 6940, 1917. 



Kearfott has two species among his cotypes representing two dif- 

 ferent genera. The California specimens are the same as Sonia 

 fliana Busck, as are also the specimens determined by Kearfott as 

 Eucosma shastana Walsingham. The type of palousana., however, 

 (a male from Pullman, Washington) is a true Eucosma with veins 

 7 and 8 of fore wing both present and separate. One of his cotypes 

 (" Pullman, Washington, 10 Aug., '98, Wash. Exp. Sta. #533, C. V. 

 Piper") in the National Collection is conspecific with the type. 



There are also in the National Collection two other female speci- 

 mens from Pullman, Washington. 



It is possible that palousana may be a synonym or local race of 

 hiquadrana Walsingham, but this can not be ascertained in the ab- 

 sence of an authentic male of Walsingham's species.

(Fig. 243.) 



Palpus white, slightly clouded with fuscous on tuft of second joint. 

 Face and head white. Thorax white somewhat marked with fuscous. 

 Fore wing with a short appressed fold in the male ; termen slanting, 

 not concave; veins 3, 4, and 5 not appreciably approximate at ter- 

 men ; white marked with dark fuscous ; on dorsum beyond base and 

 before middle a conspicuous outwardly curved fuscous patch reaching 

 to top of cell; another broadly triangular fuscous spot on dorsum 

 beyond middle; along costa several five geminate fuscous dashes; 

 also near middle of costa a square fuscous patch; from costa just 

 beyond apical third a more or less triangular spot extending in a 

 curved, somewhat irregular and variously expanded fuscous band 

 running to tornus around outer margin of ocellus; between this 

 and apex a small but rather conspicuous triangular fuscous spot; 

 another somewhat larger spot at apex; at end of cell an obscure 

 fuscous spot; white areas somewhat streaked and spotted with
