straight to near the base ; ground colour dark olive-green 

 or olive-brown, very much obscured with black marbling, 

 especially so in the basal area and in a broad ill-defined 

 band across the middle, otherwise rather mottled with white ; 

 costal margin dotted with white ; first line double, much 

 indented and greatly obscured, deep black and margining 

 the basal blackened region ; second line also black but 

 indistinct and much indented ; orbicular stigma rather large, 

 round, white or whitish, ringed with black and centred 

 with blackish-brown ; from it a small white blotch attains 

 the costa, and a series of white, or pale olive, clouds and 

 dashes passes to the dorsal margin ; reniform stigma very 

 indistinct, faintly edged with black, its outer half lying in 

 a large ovate white blotch which occupies the greater part 

 of the apical region from the costa to below the middle, 

 and is much rippled with blackish cloudy lines ; it also 

 contains a small slender dagger-streak, and is often followed 

 by cloudy white blotches similarly rippled toward the hind 

 margin and apex ; hind margin ornamented with a slender 

 white line placed in crescents which enclose black spots ; 

 cilia whitish with large regularly placed black spots. Hind 

 wings pale grey-brown, darker toward the hind margin, and

Underside of the fore wings dark grey in the middle, 

 paler at the margins, and the costa spotted with black ; 

 cilia white with round deep black spots. Hind wings 

 whitish dusted with grey ; central spot dark-brown followed 

 by a slender, curved, dark grey transverse stripe; a dark 

 gi-ey cloud lies along the anal angle ; cilia whitish with 

 large brown spots. Body dusky pale brown, legs whitish 

 with large black bars.
