line formed of curved lunules, the central part of the line 

 curving a little outwards, then bent inwards, then another 

 small outward curve before it reaches the hinder margin at 

 two thirds : hind wing with a similar discal line, but more 

 deeply curving outwards in its middle ; marginal line of both 

 wings pale, with brown lunules ; cilia concolorous with the 

 wings ; the apex of fore wings is pale, and there is a pale 

 shade outside the upper portion of the exterior line. Under- 

 side : body, legs, and wings white, outer portion of wings 

 and cilia grey ; cell-spots and outer line distinct ; a cell-spot 

 on hind wings.

 of a uniform greyish-olive colour. Wings with a brown mark 

 at the end of each cell : fore wings with a small brown spot 

 within the cell ; interior line outwardly curved, but only 

 indications of it ; exterior line commences with two white 

 lunular marks at the costa one fifth from apex, bulges out a 

 little, forming an indistinct and rather flattened grey line, 

 with pale dentations, then inwards on vein 2 and then to the 

 hinder margin at two thirds, and is continued in the usual 

 form across the hind wings, with an outward curve in the 

 centre, and edged outwardly with whitish throughout ; mar-

 fore wings with a dot within the cell rather close to the end ; 

 an interior line, slightly sinuous and outwardly curved ; an 

 exterior more or less lunular line from the costa almost straight 

 down to vein 4, then it bulges out a little with three denta- 

 tions to vein 2, where it abruptly runs in, and then straight 

 to the hinder margin at two thirds, is continued across the 

 hind wings with an outward curve in the middle: anteciliary 

 line pale, cilia concolorous with the wing. Underside pale
