middle of the disc and on the abdominal margin. Forewing with the following 

 white semi-transparent spots : a small round one in the middle of the 

 upper discoidal interspace ; two at the end of the cell, one above the other 

 the lower twice the size of the upper ; a large spot in the interspace below 

 and a small one placed in the second median interspace near its base. 

 Underside with the costa and apex widely and the entire hindwing 

 ferruginous-ochreous glossed and marbled with purple, the disc of the fore- 

 wing dark brown, the inner margin paler. Forewing with the spots as 

 above ; hindwing with a dark brown spot in the cell and a series of five or 

 six similar spots placed around the cell. Cilia cinereous, dark brown at 

 the end of the nervules. Antennae black annulated with pale ochreous 

 beneath, the club, all except the extreme tip, pale ochreous beneath.

" $ . Upperside, both wings dark vandyke-brown, suffused with purple, 

 especially on the costal and outer margins and the veins ; the cilia ochreous- 

 grey. Forewing with five small semi-transparent white lustrous spots, two 

 (the first of which is very minute) before the apex, and three discal, one 

 geminated in the cell consisting of an anteriorly outwardly convex thin 

 crescentic and a posterior triangular portion, another about the same size 

 behind and a little external to this between the first and second median 

 nervules sub-crescentic in shape, with its convexity turned towards the 

 base and a third squarish external to, and in front of, and rather less 

 than half the size of, this again between the second and third median 

 nervules. Underside, forewing lighter than above, the translucent spots as 

 on the upperside; with an indistinct submarginal band of spots darker than 

 the ground ; a dark anteciliary line ; the cilia obsoletely intersected at the 

 veins with dark, and an indistinct whitey-brown spot, touching the first 

 median nervule and the satiny patch, extending from the base nearly to the 

 outer angle and from the interno-median fold to the inner margin of the 

 wing, which bears a conspicuous fringe of slate-grey setae in part projecting 

 straight backwards and outwards from the edge and in part turned up so as 

 to spread out fanwise over the satiny ashy patch. Hindwing darker and 

 more suffused with purple than the forewing, with a dark anteciliary line, 

 but even less distinctly * intersected cilia ; with some dark mottling 

 indistinctly arranged in three bands, one subbasal and two closer together 

 discal or submarginal, and with an indistinct dot between the costal and 

 subcostal nervures, another near the end of the cell, on one side only in one
