Acidalia okakaria Ji. sp. 



Yevy uniform, finely mottled gray, with a pearly lustre on both 

 wings. Head with the vertex whitish; antennaj 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 

 du?ky 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 outwards in the middle of the wing. No 

 discal dot, or any other markings on either wings. 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 lustre ; 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 the body .38 ; fore wing .48 inch.

This species is closely allied to, but differs from Moschler's A.frigi- 

 daria in having no discal dots except on the hind wings, and these are 

 only appai-ent on careful examination. The lines are not waved, ex- 

 cept at the slight flexure of the outer line. The antennae are not 

 white above, as they are said to be in Moschler's species, and the 

 fringe is darker than his description of that of frigidaria would Indi- 

 cate, while the outer line is not pointed beneath on the nervules as in 

 the other species.
