Described from seven specimens. 



Holotype i and one paratype S, New Brighton, Pa., June (Merrick) in 

 coll. Barnes. 



Allotype Hampton, N. II., July (Shaw) and one paratype S, Wapakoneta, 

 Ohio, U. S. N. M. No. 23475. 



Paratype S , Mass. and one paratype with broken abdomen from James- 

 ville, Md., Cambridge Museum, together with a fragmentary specimen from 

 Hazleton, Pa.

Linus is also a very distinct species, with its rather narrow pri- 

 maries coarsel}' powdered with blackish scales over the white ground 

 color. None of the types is in perfect condition, but the species 

 appears to be rare so we have added as many as possible to the type 

 series. 



We have no information about the life history.

i . Pale brownish gray. Palpi with a few darker scales toward tip ; 

 small and oblique. Antennae very faintly dotted above. Legs mixed gray 

 and whitish, tarsi darker at tips of joints Fore and mid tibiae with slight 

 scale tufts. Spurs of hind tibiae short. 



Primaries light gray-brown, sometimes mixed with white scales. Costa 

 with a gray-brown dash over base of cleft and a longer one, sometimes divided 

 into two, beyond. Cleft preceded at a short distance by a slight dark spot, 

 obliquely prolonged in a faint shade toward costal dash. This spot is sometimes 

 no darker than the ground color, indicated by the paler scales which follow it. 

 There are a few darker gray brown scales scattered over the wing. Fringes 

 very pale gray brown with a few whitish areas. Secondaries and their fringes 

 scarcely darker than primaries. 



9 . Much paler than $ . White with the darker marks of the S present 

 but pale brownish gray. Fringes of primaries extremely pale, whitish. Under 

 a lens normal specimens show pure white clusters in the fringes, but in the 

 palest specimens they are entirely pure white. The secondaries are faintly 

 tinged with gray. Some specimens are almost pure white, but none in our 

 possession fails to show the costal dash over base of cleft and mark before 

 cleft under a lens. Expanse 17-23 mm.
