cell ; discocellulars pale opaline blue, a spot of almost the 

 same colour on the interno-median area beyond the middle ; a 

 large pearly-white patch or abbreviated fascia from costa just 

 before apical third to below first median branch ; the extre- 

 mity of this fascia is conical and its outer edge inarched j a 

 broad, oblique, shining, lilac band from costa near apex to 

 outer fourth of inner margin ; a slender, silvery wdiitish, 

 wavy line between the last two bands ; inner border shining 

 snow-white to beyond middle; fringe also snow-white, with 

 three black spots on apical third : secondaries with the basal 

 two thirds pearly white, bounded externally by a slightly 

 irregular, oblique, black stripe (enclosing a silvery whitish 

 line) from outer third of costal margin to anal angle; inner 

 half of external area occupied by a shining lilac band, and 

 outer half by a blackish-brown border ; fringe snow-white, 

 marked with blackish, and with a black subbasal line towards 

 anal angle : outer surface of palpi, eyes, and shoulders deep 

 bronzy brown, almost black ; face testaceous, with white mar- 

 gins ; proboscis, inner side of palpi, and tegulsfi pure white ; 

 vertex of head sordid whitish, antennse greyish, thorax dark 

 brown, becoming lilacine greyish behind ; abdomen bronze- 

 brown, greyish behind, with blackish lateral stripe and anal 

 tuft and snow-white lateral borders. Wings below without 

 the lilac bands, silvery lines, or opaline spots of the upper 

 surface : primaries with the basal third white, so as to include

Allied to Nosophora, Lederer : primaries elongate-trian- 

 gular ; costal vein terminating just beyond the middle of the 

 costal margin ; subcostal live-branched, the first branch 

 emitted some distance before the end of the cell, the second to 

 fourth some distance beyond, the fifth from the end of the cell 

 in the position of an upper radial, and near to the upper 

 radial, the lower radial, second and third median near together 

 from the posterior angle of the cell : secondaries with the 

 costal margin arched nearly to the middle, and thence straight 

 -to apex, the outer margin from apex obliquely deflexed and 

 coming to a point at the end of the second subcostal branch, 

 thence suddenly excised and running in a very slight arch to 

 anal angle, whence it curves gently inwards to the abdominal 

 margin. Under surface of secondaries coarsely scaled towards
