waved line. Extra discal line distinct, less so at costa, with a large angle 

 to cell, then curved boldly outward, reaching in a straight or wavy line to 

 inner margin, about two-thirds from base. Outside this and parallel is a 

 gray shade line replacing the brown line of fore wings. Often a few brown 

 scales appear in this line, visible under lens. A conspicuous white line- 

 like space follows the extra discal line, beyond which the single subter- 

 minal is more or less distinct, but di^es not dissolve into points in any of 

 my specimens. Discal dots roimd and black, usually distinct on fore 

 wings, smaller and sometimes wanting on hind wings, in the latter never 

 included in the basal line, as in cotnptaria, Walk. Beneath dusky, the 

 extra discal and subterminal lines distinctly reproduced on both wings, 

 the space between them being less dusky, often the basal line is faintly 

 shown. Intervenular line at margin faint but apparent. Discal dots 

 obvious. Legs dusky, fore tibia dark gray, tarsi ringed with yellowish. 

 Abdomen in ^ above dull white, each segment anteriorly ringed with 

 dark gray, beneath dusky-yellowish. Anal tuft yellowish, in $ dull white, 

 not ringed, dusky at base. 



Type ^ and 9 ; coll. R. F. Pearsall. 



I have before me 25 ^^ 's, 10 9 ^^, taken in the Catskill Mts., from 

 June 4 to July 15. As compared with coniptaria, Walk., the wing texture 

 is much heavier, the ground colour clear white, not bluish-ash, and the 

 lines diffuse. One male is entirely suffused with dark gray and brown 

 scales, the conspicuous white line beyond extra discal showing out vividly; 

 indeed, the tendency to suffusion is a characteristic of the species, and 

 makes intelligent description most difficult. The large round spot 

 opposite cell, so marked a feature in lucata, is shown to a less degree in 

 this species, but combined with a wide white discal space it has produced 

 the form confounded with the latter, and easily distinguished from it by 

 the margiual intervenular line not present in iucata. 



The species concerned will, I trust, finally rest as I now place them.
