apex followed by a white pencil in the fringes ; second with two vague outer 

 marginal dots. Fringes brownish gray with a very variable mixture of white

Distribution: B. C. (June) through Colo, and Cal., (June to 

 Sept.) to Ariz. (May to Sept.) and southward. Type localities: grisc- 

 sccns, Rogue R.. S. Ore., acrias, Colo. ; bchri'i. San Bernadino Mts., 

 Cal. 



From Meyrick's comparisons and our own examination of the 

 types of behrii we are satisfied that the above synonymy is correct. 

 We know no species which can be confused with this. Two of Wal- 

 singham's types are in the Fernald collection. 



Aside from Walsingham's note that the eight specimens of the 

 type series were reared from Artemisia sp. in May, we know nothing 

 of the early stages.

 Brownish white to grayish, often darker toward the costa ; head tinged 

 with brown above and in front, thorax usually darker across lips of patagia 

 and abdomen sometimes darker except a dorsal band containing central dark 

 dots and slender black dashes in terminal half; scales raised at posterior mar- 

 gins of segments. Fore and mid tibiae tufted. Tarsi with dark annuli, very 

 variable in extent and shade and sometimes lacking. Antennae with or without 

 dark dots above. Palpi short, oblique. 



Primaries rather slender, lutenous to brownish white. Veins in lobes 

 and radial stein frequently pale. There is a variable irroration of blackish 

 scales which tends to collect between the veins and in tlie basal half of the wing; 

 these scales are often very few and widely scattered. Wing at base of cleft 

 whitish, prceded by a black or brown dash which curved outward toward costal 

 blackish dash above base of cleft. Darker specimens may also have two dots
