coucolorous, with paler bases. One paratype is much paler and 

 more evenly colored than the other specimens and has a series of 

 terminal dark dashes. Secondaries white, veins darker: terminal 

 area sparsely sprinkled with dark scales ; fringes white. Expanse 

 about 40 mm. 



Three males from Eureka, Utah (Spalding) : holotype Sept. 2T, 

 paratype Sept. 21, and paratype Aug. 24, in coll. Barnes. 



This species appears to be most closely related to pectinata, and 

 we place it at the head of the genus. The peculiar shade of brown, 

 less smooth vestiture of primaries, and white secondaries, separate 

 it readily from pectinata.
