Forewing: basal area extending beyond fourth, outer edge vertical, straight, 

 except one indentation below fold, mottled light brown, darker in outer half and 

 edged with dark brown. It is followed by a broad white fascia, the inner half of 

 which reaches costa ; a third below it broadens horizontally, equaling the width 

 of basal area, thence in a dentate line to dorsal margin. This is followed by a 

 light brown fascia, well defined on lower two-thirds of wing ; in the upper third 

 it runs obliquely inward to costa, and on inner edge below costa sends a short 

 line into the white at its narrowest part; there is a dot of raised black scales on 

 its inner edge just above fold ; the width of this brown fascia is equal to width of 

 the white ocellic patch beyond, the latter is large, with straight vertical edges, 

 and reaches to upper third of wing, it is dull white in the middle and shining 

 white on the sides, between its upper half and termen is a wedge-shaped brown 

 streak. The outer half of costa is marked with three brown spots, increasing in 

 size outwardly and a fourth brown spot in apex, before the first and between each 

 pair is a broader white spot, divided by a narrow brown oblique line. Between 

 these costal spots and the upper edges of the brown and white fascise is a hori"
