brown, like the legs. Fore wings spotted with pale brown, and crossed by two 

 broad, broken, light-brown lines; the inner on the inner quarter of the wing 

 curved and consisting of about three spots, one on the costa, one on the inner 

 margin, one on the median vein (the middle one often wanting). Outer line 

 curved, often forked on the first median cell, sending a smaller branch straight 

 toward the apex ; this branch often obsolete, and the whole line obsolete in 

 the middle of the wing, and sometimes wanting on the costa. The same 

 line is continued on to the hind wing ; it is usually obsolete in the middle of the 

 wing. No inner line on the hind wing. Fringe yellow, spotted with brown 

 at the ends of the venules. Beneath as above. 



Length of body, <?, 0.75; of fore wing, cf, 0.68-0.85, 9, 0.95-1.06;

 Massachusetts, (Sanborn and Peab. Acad. Sc); Illinois (Clemens); New 

 Hampshire (Walker); Detroit, Mich. (Mus. Comp. Zool.); New Orleans, La. 

 (Mus. Peab. Acad. Sc); abundant at head of Plum Creek, Colo. (Lieutenant

A common form, at once known by the bright ochre-yellow wings, its 

 large size and broadly pectinated male antennae. The wings vary much in the, 

 extent of the spots and bauds. 



One male specimen from Philadelphia (Fnt. Soc.) is almost immaculate, 

 with unusually broad hind tibiae, also unspotted. 



Larva. — The. body gradually increases in size to the segment bearing 

 the first pair of abdominal legs. The head is flattened so as to be square above, 

 and is whitish-green, with three longitudinal brown lines. The prothoracic 

 ring is concolorous with the head, from which two brown lines extend, form- 

 ing an inverted v on the hinder edge. The body is pale grass-green above, 

 with the sides swollen. There are four minute black dots on each segment; 

 a whitish, indistinct, subdorsal line, and a lateral white line extending to the 

 sides of (he anal legs. It feeds on the strawberry and currant in June, 

 entering the pupa state June 12. The moth appears at the beginning of 

 July.
