and bend, and join slender lines on tiie nervures. Hind 

 wings smoky wbitisli-tjroun. 



Antennas of the male short, thick, densely ciliated, grey ; 

 palpi short and blunt, dark brown : face flattened, whitish- 

 grey ; head and neck-ridge tinged with fulvous ; thorax 

 smooth, pale grey ; abdomen pointed, brownish-grey, with 

 slender black bars across the first two segments ; anal tuft

 rounded ; hind margin long and evenly curved : dorsal 

 margin also a little rounded ; colour pale silvery-grey, 

 leaden-grey, or brownish-grey ; basal line black, slender but 

 distinct, once angulated outwards; first line triple, black, 

 sinuous, and sharply angulated below the middle ; second 

 line also triple, sinuous, very oblique, angulated at every

 is an equally black, slender single line, more direct, j-et bent 

 outwards, so as to touch the elongated perpendicular black

 the second line blackened ; — these markings, which are 

 clear and sharp, give the wings a beautifully laced aspect — 

 extreme margin edged by a black line ; cilia whitish-grey. 

 Hind wings not elongated, rounded behind, greyish-white ; 

 the base and the nervures faintly dusted with grey or black ;

Underside of the fore wings pale grey- brown, with the
