 species. Fringe long, dusky, checkered with white opposite the ends of the 

 venules. Wings more thickly scaled than usual, and venules not so prominent. 

 Hind wings dark slate-color; fringe spotted with white. Fore wings bencsatli 

 nearly concolorous with the upper side of the hind('r paii'; a slight ferru- 

 ginous tinge toward the costa. Hind wings much paler, cinereous, with red-

 wing.

Taken half-way between the Summit and the "Ledge", Mount Wash- 

 ington, N; H., August 18 (Shurlleff) ; Tuckermaii's Eavine, Mount Wash- 

 ington (Sanborn). 



This sex may be determined by its dark slate-color, without any rust- 

 red tinge on the fore wings above, and less beneath than in the female ; also 

 by the large teeth of the outer band and the narrower inner band. 



y *• — Ferruginous ashen slate-color; front reddish. On the fore wings, 

 a basal oblique linear cross-line; a middle broad line, regular, and angulated 

 distinctly just below the costa, below which the line is double. Discal dot 

 small but distinct. Outer line narrow, doubly cnrved, and finely zigzag, on 

 the outer side twice dilating, and finely toothed, opposite which are two rusty 

 red spots, interrupted by two faint lines. Without, a darker line proceeds 

 from the middle of the wing oi)liquely toward the apex. Fringe long, spotted 

 conspicuously with white. Hind wings iilain, slate-colored, with no marks. 

 Beneath, the fore wings are slate-colored, l)ecoming rusty-red toward the 

 costa and outer edge: hind wings dull reddish beneath, with a slight purplish 

 tinge, and an extradiscal dark line more distinctly marked than in the other 

 species. Fringe not so distinctly spotted with white as on the fore wings. 



Length of body, 0.35; length of fore wing, 0.50; expanse of wings, 

 1.10 inches. 



Readily known by the red under side, the broad reddish band, the outer, 

 waved, finely dentate band, and the two ferruginous spot-: opposite each l)cnd 

 of the line.
