gives 5 points of difference; the more slender body parts, the greater 
expanse, the large open subreniform, the paler hind wings, and the 
more acutely dentate t.p. line. But all these vary through both species.

fic distinction.

Primaries dark wood brown, or blackish brown, slightly silky, darker shaded in 
the subbasal space, on the costa, above discal cell, and subapically; t.a. line geminate, 
outer line sometimes less distinct; reniform shaded with black; subreniform pale; t.p. 
line with M prominent, and sinus heavy; s.t. line geminate, with grayish between. 
Secondaries deep yellow, internal margin and base dusky; median band not much 
constricted. Expands 85—95 mm. Habitat, Hast of Plains. Food plant, Walnut, 
Hickory and Persimmon, (Auct. Koebele).
