line, obscured by the dark ground color of the wing. A square pale 

 yellow discal patch, resting between the small dark discal dots. Trans- 

 verse posterior line more distinct, brought into relief by a diffuse pale 

 yellow shade, which latter obtains principally opposite the disc within 

 the t. p. line. This latter is projected outwardly opposite the disc, 

 where it is serrated ; below the yellow shade it becomes lost, owing to 

 the dark color of the wings. A terminal dark shaded line resting on 

 the external edge; fringes obscure brown, discolorous with the wing. 

 Secondaries resembling primaries ; at base fuscous, the dark color ob- 

 scuring a discal spot apparent beneath ; medially pale yellowish testa- 

 ceous; a distinct median line, followed outwardly by an interrupted 

 yellowish shaded line, so as to be brought into relief by the yellowish 

 color on both sides, of the mtrmal conformation, serrated, outwardly 

 projected opposite the disc. A terminal blackish interspaeeal line and 

 fringes, as on primaries. Beneath, paler than above; primaries, darker 

 shaded, with a slight opaline reflection; secondaries, wholly obscure 

 ochreous. On both wings the ornamentation of the upper surface is 

 repeated, the lines are here narrowly interrupted and macular.

AVings full. Primaries, pale ochreous, with darker sub-terminal

 by an obscure shade, deeper, more brownish than the ground color of 

 the wing. Discal spot, sub-obsolete, whitish. Transverse exterior line, 

 white, neatly margined by narrow dark coincident shade lines of which 

 the inner is more distinct. The line itself is greatly and roundedly 

 outwardly projected over the middle of the wing; towards the internal
