28 AMERICAN LKPIDOPTERA. 



Forewing: light gray, with large spots aud fascise of blackish-brown. The 

 basal area extends in middle of wing to inner fourth, receding to costa and dor- 

 sum, it is black outwardly, gray towards base ; on inner third of costa is a large 

 black spot and another before anal angle on dorsum, a third one is between these 

 two in the middle of wing over outer third of cell, the three forming a broken 

 fascia. On the costa are three large black spots, with a fourth in apex, which 

 enlarges below, then contracts and follows termen to anal angle. The gray areas 

 between these dark spots are vertically strigulated with blackish-brown. This 

 description is from the most intensely marked specimen, in others, the dark 

 spots are contracted and the gray color predominates, sometimes dividing the 

 spots, and in others the large dark spots are almost lost. Cilia yellowish-gray, 

 dusted with fuscous. 



Hindwing: dark gray, cilia paler; underside both wings a uniform gray, with 

 costal spots repeated.

Encosma fofaiia sp. nov. 



Expanse 21 mm. 



Head, palpi and thorax dark ochreous-gray, heavily dusted with fuscous, and 

 dotted with black on patagia ; antenna dark fuscous; abdomen grayish fuscous, 

 tuft ochreous-fuscous; legs gray, banded with white and powdered with dark 

 fuscous. 



Forewing: whitish-gray, spotted and strigulated with black-brown. There is 

 an obscure dark fascia from middle of costa obliquely towards anal angle, it is 

 well defined only in upper third. There are four rather large black dots on costa 

 beyond it, the fourth being in the apex ; below the second of these dots are two 

 superimposed irregular rings, each composed of five or six dark dots; below the 

 third is another such ring, and below it a line of dots before termen above anal 

 angle. The basal area is not definitel.v defined, all of the inner half of wing is 

 an irregular mass of large and small dots on the whitish-gray ground. Cilia yel- 

 lowish-gray, preceded by a darker line. 



Hindwing: smoky gray, cilia the same, but tips of scales whitish ; underside 

 yellowish-gray. 



Underside forewing: yellowish-gray, dark spots repeated along costa, and rows 

 of dark dots between the veins beyond the cell. 



One % specimen. Berthoud Pass, Colo., Aug. 22d ; collected 

 by A. J. Snyder. 



This species strongly resembles dodana Kearf., and may prove to 

 be an extreme variety of it. There is a certain formation of the 

 markings, however, that leads me to believe it is distinct.
