This common species is as abundant as A. k-lineata in the Northeastern 

 States, and may be recognized by the ochreous-gray body and wings, the 

 blackish front, 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 A. k-lineata. There is no species in the Northeastern States 

 with which it can be confounded. It is very closely related to A. californiata, 

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

 Kansas and Nebraska do not differ from eastern ones, and show no approach 

 to californiata. 



I append my original description of A. okakaria: — Very uniform, finely 

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

 whitish ; antennae finely ciliated, gray above, with blackish fine scales ; front 

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

 above. Wings with three dusty obscure stripes ; the basal line oblique, not 

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

 parallel line once waved, and flexed outward in the middle of the wing. No 

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

 dark line ; fringe long, concolorous with the rest of the wing. Hind wings 

 with two lines, 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 fore 

 wing. Beneath, very uniform gray, but little lighter than above; at the base 

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

 lines as distinct as above, the outer more so, and flexed as above. No discal 

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

 above, paler beneath. 



Length of body, 0.38 ; of fore wing, 0.48 inch.
