hind marginal space sometimes clouded with dark brown ; 

 extreme edge obscurely dotted with black ; subcostal region 

 and space round the stigmata often clouded with darker 

 brown, which in some instances extends across the wing as 

 a dark central shade ; cilia shining brown, divided by a 

 darker line. Hind wings rather ample ; apex and hind 

 margin rounded ; shining, clear, transparent white, nervures 

 sometimes faintly tinged with brown ; extreme hind margin 

 brownish ; cilia white. 



Female very different in colour, which in it is usually dark 

 umbreous, grey -brown, or blackish brown, nearly uui- 

 colorous, with the markings so obscured as to be barely 

 visible ; but occasionally it is paler umbreous, with darker 

 nervures, and the markings more distinct, the dark reni- 

 form stigma especially so; cilia always light brown, almost 

 yellow-broAvn at their base, but divided by the dark 

 line. Hind wings clouded with grey-brown, especially 

 along the hind margin ; nervures dark brown ; cilia white. 

 Head and thorax sometimes dark-coloured in accordance 

 with the fore wings, often paler. Not very similar to the 

 male. 



Underside of the fore wings in the male shining whitish, 

 the whole under surface of the discal cell downy with long 

 grey scales ; beyond the middle is a white transverse band, 

 followed by a grey line. Hind wings white, with the costal 

 region broadly dusted with grey, and a grey line along the 

 hind margin, cilia white. Body dark grey mixed with 

 whitish, anal tuft browner ; leg tufts dense, purplish-brown 

 in front, white behind ; legs long and bristly, dark brown, 

 barred with white. In the female the underside of the 

 wings is but little darker, but the body and leg tufts are 

 more smoky-grey, the front legs blackish, with white bars, 

 and the hinder legs whiter. 



In the male the ground colour occasionally varies to pale

 forms, the markings are in some instances very sharp and
