 Gray brown. White line over eye. Antennae darker above than below. 

 Palpi as in the preceding species, moderate, whitish above ; third joint small 

 and not e.xceeding vestiture of second. Abdomen dark, with mixed blackish, 

 ochreous and white scales. Paired dots in posterior margins of segments above 

 and two parallel white lines below. Legs whitish on one side as in the related 

 species. 



Primaries dark brownish gray on costa, blending into ochreous or pale 

 gray on inner margin, and heavily irrorate with white in most specimens and 

 with scattered black scales in the darker forms. The white scales vaguely 

 checker the costa and are heavy, as a nile, on the terminal area of both lobes. 

 Cleft preceded by two blackish dots, usually fused. The first is usually merged 

 into a costal shade which is sometimes extensive enough to form a rather vague 

 discal triangle such as occurs in Platyl^tilia. First lobe with a heavy oblique 

 blackish shade, margined outwardly with white and preceded on costa by a 

 white dash. That part of the shade nearest the cleft is a darker, almost longi- 

 tudinal, fusiform dash which is sometimes isolated by the surrounding white 

 irroration. The white outer margin of this patch is continued on the second 

 lobe. There is usually a blackish dot near middle of cell. Fringes white in 

 cleft, with grayish clusters before outer margin, elsewhere gray, white below 

 apices of both lobes. On outer margin they contain a basal row of blackish 

 scales. Secondaries brownish gray with concolorous fringes. Expanse 18-24 mm.

The type series of exclamationis was taken in the Siskiyou Mts. 

 "on the borders of California and Oregon", in June, and included 

 seven specimens. The Fernald collection contains one male paratype 

 from this series, which we have examined. It is the most smoothly 

 gray specimen which we have seen, and it is scarcely to be thought 

 strange that, with limited material, Fernald described the same species 

 as coloradensis. The type series of the latter includes a male type and
