tint, but deep ochreous beyond. Inner line faint; discal dot very distinct ; 

 outer line distinct, nearly straight. Beneath uniformly ochreous; with the 

 outer common line very distinct, consisting of a row of blackish dots; on the 

 hind wings, it is bent opposite the distinct discal dot. The base of the fore 

 wing is rather densely shaded with dark specks, and there is a very faint 

 submarginal shade. Legs concolorous with the body, speckled. The wing 

 is whitish in the middle, with the white spot distinct, In one case, the 

 margin of both wings above is lilac-ash.

This species is perhaps more common than the other The male may 

 be distinguished by its smaller size, by the wings being more ochreous, by 

 the distinct discal dots, and by the rather distinct median white band on the 

 fore wings. The female differs greatly from the male, being much larger 

 and with the wings more serrate, the two inner lines more or less obsolete, 

 the border of both wings being much darker than the inside of the wing, 

 the border sometimes having a lilac tinge. From the female of P. subato- 

 maria, it differs in its still smaller size, in having usually but one subapical 

 spot, instead of three, as is usually the case in the other species, and in the 

 outer border of the wings being darker or more decidedly ochreous. The 

 wings are serrated much alike in the two species, but more decidedly in the 

 female of P. deplanaria than that of the other species. It is a very difficult 

 genus, and impossible to study properly without a large amount of specimens. 

 It would be easy for one to be led into making half a dozen "species" if he 

 had but one or two specimens of each variety.
