8 t? and 4 ?. — Front of head and palpi concolorous with rest of body. 

 Of exactly the form of T. argittacearia ; the antennae pectinated in the same 

 manner. Uniformly Scotch-snufF brown, with no markings except a few 

 darker costal specks, sometimes four larger equidistant spots, with four 

 obscure lines proceeding from them. A slight, dark, discal spot on each wing. 

 Beneath, uniformly deep dull-ochreous, with no markings or discal dots. 

 Fringe a little darker above and beneath than the wings. Light ferruginous 

 reddish-brown, ochreous on the costa, darker toward the outer margin; dusted 

 with transverse strigae, especially conspicuous on the costa of the fore wings. 

 On the fore wings, three transverse dark-brown lines, dilating broadly on 

 the costa, the two basal ones angulated on the median vein, the third curved, 

 especially on the anterior half of the wing; the outer triangular costal spot 

 half-way between the third line and the tip; fringe long, dull, smoky. 

 Hind wings somewhat paler ochreous, with two very distinct dark lines; 

 the inner straight, the outer obtusely angulated in the middle. A narrow 

 discal dot on both wings, but more distinct on the hind wings. Beneath, 

 bright ochreous, tinged with reddish on the venules; the lines re-appear 

 beneath, being broader and more diffuse; the wings speckled thickly with 

 ferruginous on the basal half. Legs very long and slender; tibiae and tarsi 

 dark; femora paler, speckled. 



Length of body, <?, 0.42, 9, 0.40; of fore wings, $ , 0.50, 9, 0.45-48; 

 expanse of wings, 92-1.12 inches. 



Maine, June 25 to July 8, in pine-woods (Packard); sides of Mount 

 Washington, N. II., July (Morrison); Natick, Mass. (Stratton. Mus. Bost. Soc. 

 Nat. Hist,). 



This form may be recognized by its resemblance in the shape of the 

 wings and antennae to T. argittacearia, and by the uniform dull snuff-colored 

 wings and dull-ochreous under side of the males. The females differ 

 unusually in coloration, being bright-ochrcous, with three dark-brown lines. 



Our examples are so closely similar to European specimens (male and
