patch ; two snow-white costal patches, the first larger than the 

 second, its margin denticulated and bounded on each side by the 

 discoidal spots, which are black and annular; three black spots 

 bounded externally by a rectangular red-brown marking beyond 

 the cell ; an irregular line of white scales crossing the disc towards 

 outer margin, partly enclosing two black dots towards costa, con- 

 fluent, and forming an oblique dentated line towards external 

 angle ; a submarginal series of black spots with white internal 

 borders ; a large white spot on the fringe below the middle and a 

 narrow whitish dash crossing it longitudinally at apical third ; the 

 remainder of the fringe is divided by a central blackish line, beyond 

 which it is glossed with grey; secondaries straw-yellow, with a 

 broad external brown border ; basal half of fringe occupied by a 

 brown stripe, separated from the external border by an ochreous 

 line ; outer half of fringe white ; thorax white, the collar slightly 

 sordid ; abdomen ochreous banded with brown, the base and anus 

 white ; wings below stramineous ; primaries clouded with grey, 

 indicating the pattern of the upper surface ; secondaries with 

 three dark grey costal spots, shot with rosy cupreous, the third at

 wings less sharply denned ; the discal line of white scales not 

 terminating in a dentated line as in A. nivipicta, but uniform

 coloured, marked with three dusky spots, one at apex, one above 

 the middle, and one at external angle ; secondaries bronze-brown, 

 greyish towards the base ; body whity brown ; primaries below 

 smoky grey, with a golden gloss; costal border white at base,
