a mere line dorsally on posterior edge. Beneath ashen, the pale band as 

 above showing white, and all lines apparent, but much finer, the heaviest 

 being the intra-discal and the outer bordering or geminate pale lines, 

 while the extra discal becomes a row of black dots on veins. The lines 

 are broad and dark at costa on primaries, and the discal dot large, linear, 

 and jet black, on all wings. Marginal line and fringes as above. Body 

 and legs ashen, sprinkled heavily with dark brown. 



Type: No. 13365; one male and one female, the former 

 from Southern Arizona (Poling), without date, through the 

 courtesy of Dr. Dyar, I have been allowed to retain. The 

 latter is the type, so-called, of Tep. niveifascia Hulst (Can. 

 Ent., xxx, p. 115), recorded from Oregon. It will be noted 

 that it is not even congeneric with the true niveifascia, the 

 type of which is in the Hulst collection at New Brunswick.
