 the costa being very straight and the outer (idge more oblique and longer in

 white, clouded with dark brown. Instead of the usual two very distinct lines, 

 there arc four indistinct ])arallel lines ecjually indistinct on account of the 

 speckled and spotted surface of the wing. The (wo inner lines are parallel 

 and similar. The two outer lines are nearer together and more or less bndien 

 and diffuse, with a white line between and beyond them, the submarginal 

 white Hne being a little sinuous. The usual marginal, dark, broken line on 

 both wings. Hind wings wnth no distinct lines, but mottled with brown, and 

 with some ochreous scales; di-scal dot obscure. TIk; fringe is lonff, with two 

 brown hair-lines externally. Beneath, both wings alike, quite uniformly 

 mottled with brown and ochreous, but with no lines, though the discal marks 

 are slightly indicated, not being [)resent ai)ove on the fore wings.
