This common species is as abundant as A. A-.li?iea/a in tlie Xorlliea.stern 

 States, and may be recognized I)y the oclircoiis-gray bo<ly and wings, the 

 blackisli I'ront, the hind tarsi being slightly longer than the tibia-, and by the 

 presence of discal dots and marginal lines; the wings are much less angu- 

 lated than in J. A-Iinenfa. 'I'here is no species in the Northeastern States 

 with which it can be conlbuiided. It is very (•losely related \o A.raliforniata, 

 but is much jialer, less hairy, with distinct discal dots. The examples from 

 Kansas and Nebraska (1« not diU'er from eastern ones, and show no apjjroach 

 to californiata. 



I append my original description of^ yl. okakarin : — Very uniform, finely 

 mottled gray, with a pearly luster on both wings. Head with the vertex 

 whili.sli; antenna^ tinely ciliated, gray above, with blackish tine scales; front 

 black, orbits with a few gray scales. Palpi black, with a few gray scales 

 above. Wings with three dusty o!)scure stripes; the basal line oblique, not 

 zigzag, obsolete on the costa and inner edge; a mesial obliipie line; the outer 

 parallel line once waved, and flexed outward in the middle of the wing. Xo 

 discal dot or any other markings on cither wing; edge with a very narrow 

 tlark line; fringe long, concolorous with the rest of the wing. Ilind wini^s 

 with two Unes, the inner very obscure, the outer more distinct, curved, and 

 sinuate slightly in the middle ; edge of the wing and fringe just as in the tore 

 wing. Beneath, very unitbrm gray, but little lighter than aljove; at the base 

 of the wing, a pearly luster; darker on the costa and outer edge, with the 

 lines as distinct as above, the out(;r more so, and tlexed as above. No discal 

 dot on the fore wing; that on the hind wings is nearly obsolete. Legs dark 

 above, paler l)eneath.
