Whity brown. Primaries are traversed by five dusky 

 wavy lines ; the third of these passes through two dark brown 

 marks, one on the inner margin and the other above third 

 median nervule; the fourth and fifth lines are diffuse. 

 Secondaries are traversed by a dusky diffuse central line; a 

 wavy outer line and two dusky dentate bands beyond. All 

 the wings have a brownish discal dot, that of secondaries 

 placed on the central line. Fringes rather darker than the 

 ground-colour, and preceded by a series of black dots con- 

 nected by a fine dusky line. Under surface : primaries 

 suffused with dusky ; beyond the discal spot, which is linear, 

 there is a faint blackish line and indented band : secondaries
