12. EPIBLEMA INSIDIOSANA, new species. 



(Fig. 263.) 



Palpi and head white shaded with pale olivaceous fuscous. Face 

 white. Antennae grayish white. Fore wing white marked and 

 mottled with pale fuscous of a somewhat olivaceous tint ; costa evenly 

 and conspicuously strigulated with narrow fuscous dashes from base 

 to apex; a well-marked basal patch with outer margin somewhat 

 irregular but nearly vertical ; on dorsum before ocellus a large dark 

 blotch fusing with a similar dark shading above the ocellus ; ocelloid 

 patch white with a single central longitudinal dark line ; cilia white, 

 dusted basally with fuscous. Hind wing smoky fuscous; rather 

 dark; cilia whitish with dark basal and terminal shading. Legs 

 white on inner sides ; on outer sides fuscous, banded with white. 



Male genitalia of type figured. 



Alar expanse. — 10-14.5 mm. 



Type. — In collection Barnes. 



Paratypes. — Cat. No. 24825, U.S.N.M. Also in American Museum 

 and collection Barnes. 



Type locaMty. — Southern Pines, North Carolina. 



Food plant. — Unknown. 



Described from male type and 10 male and two female paratypes 

 from Southern Pines, North Carolina ("June 1-7" to "July 16- 

 23 "), all from Doctor Barnes's collection. 



It is very similar to sosana Kearfott in color and markings but 

 without the yellow patch on mid dorsum of fore wing and the yellow 

 ocelloid patch so characteristic of the latter species. The basal patch 

 is also different in the two. In sosana its outer margin is slanting, 

 the patch being wider on costal than on dorsal margin of the wing, 

 while in insidiosana it is the same width above and below, with the 

 outer margin nearly vertical.
