314 LEPTDOPTERA. 



with blackish-grey, in which a subterminal irregular line of 

 pale dots is perceptible ; orbicular stigma round, whitish, 

 ringed, and often centred, with black ; reniform stigma 

 indistinct, dark grey, edged with black, and much obscured 

 by a broad blackish transverse perpendicular shade through 

 the middle of the wing ; claviform stigma black, large, and 

 conspicuous ; extreme hind margin dotted with black ; cilia 

 light brown, shaded and lined with dark grey. Hind wings 

 white, with the nervures and hind marginal line faintly pale 

 brown ; cilia white. 



In the female the ground colour of the fore wings, with 

 that of the thorax, is more uniform, of a deep shining dark 

 grey or blackish-grey ; orbicular stigma white, ringed with 

 black, very conspicuous ; reniform stigma grey, edged with 

 black ; claviform small, black ; remaining markings obscured 

 by the dark ground colour. Hind wings pure clear white, 

 or else tinged with brownish along the hind margin, and 

 having brownish nervures; body rather stouter, antennas 

 simple. 



Underside of the fore wings of the male dark grey, except 

 the dorsal region, which is broadly glossy white ; under 

 surface of the discal cell covered with long fluffy grey scales ; 

 costal and hind margins rather pale. Hind wings whitish, 

 with the costal area dusted with dark grey ; beyond the 

 middle a slender dark grey transverse stripe is visible, 

 mainly upon the nervures ; on the hind margin are three 

 or four blackish dots. Body yellowish-white, barred with 

 dark grey ; leg tufts mixed grey and whitish, legs very 

 bristly, grey, banded with white. Female similar. 



Variation in this species is not great ; in the male it 

 consists in greater or less clouding of smoky-grey on the 

 fore wings ; in the female mainly in the distinctness of the 

 stigmata, or their suffusion with black colouring — which 

 occasionally even obliterates the white orbicular, leaving the 

 fore wings wholly smoky-black. In this sex the hind wings 

 are rather uncertain, being in some examples pure white.
