Ground color ash gray, a little mottled with brown, giving it a 

 somewhat marbled appearance. Head and thorax without defined 

 markings. Primaries with the basal line geminate, brown marked on 

 the costa only. Transverse anterior line geminate, the outer line brown 

 and more or less obsolete, the inner line blackish, also more or less 

 obsolete; q^ a whole quite evenly oblique, outwardly. The median 

 shade is indicated by a smoky streak from the costa, extending 

 obli(]uely between the ordinary spots. Transverse posterior line black, 

 single, preceded by a slightly paler and followed by a brownish shade. 

 It is outwardly bent over the cell, strongly toothed* on veins 3 and 4, 

 and less so on veiii one. A vague, indefined, irregular, pale subterminal 

 line. A series of smoky marks at the base of the fringes, beyond which 

 these are cut witli black. There is a distinct black basal streak, which 

 extends through the transverse anterior line and is forked from the 

 lower side at about its middle. The black dash opposite the anal 

 angle extends through the transverse posterior line, and is well marked 

 and quite neatly detined. The ordinary spots are evident, though not 

 prominent; the orbicular is round or nearly so, a little paler than the 

 ground color, and outlined by smoky scales; the reniform is of moderate 

 size, kidney shai)ed, very imperfectly outlined, the center just a little 

 brown shaded. The secondaries are soiled whitish, in the female 

 smoky toward the outer margin. Beneath ])Owdery, the disk of pri- 

 maries smoky in the female, a more or less evident outer line and 

 discal spot in both sexes.

Hahifat. — Canada, southward to Georgia, west to the Mississippi; 

 central New York in June; Minnesota in July. 



This is quite a widely distributed species, though nowhere common. 

 It is very constant in its general appearance; and in the examples that
