Fore wings pale mouse-colour, in the male with no 

 markings but the slightly darker cell-spot and an ill-defined 

 exterior line just beyond it ; fringe concolorous, with a fine 

 pale basal line, followed by a thick darker one. Hind wings 

 whitish for two thirds ; like fore wings in the marginal area, 

 beyond a curved, slightly wavy, subterminal line. In the 

 female the fore wings are shorter, slightly tinged with 

 ochreous ; the exterior line is distinct, being edged with 

 paler, and forming a slight sinus outward in the middle, and 

 the discal dot is preceded by an indistinct vertical darker 

 shade ; the hind wings are paler, with discal dot and sub- 

 terminal line more distinct. Head, thorax, and abdomen all 

 concolorous, paler in female than in male. Underside glossy, 

 with hardly any markings ; the fore wings darker than the 

 hind ones.
