ments whiter. Fore wings rather broad ; costa strongly 

 arched beyond the middle ; apex obtusely anguiated ; hind 

 margin but slightly oblique, hardly rounded; dorsal margin 

 very straight; shining black-brown with a reddish or pur- 

 plish gloss, and much dusted with white ; first line oblique, 

 broken in the middle, broadly white ; second line sinuous 

 but erect, narrow and obscurely white, but more distinct at 

 the costa ; just before it, toward the costa, is a large patch 

 or cloud of white dusting, which encloses two perpendicu- 

 larly placed black dots representing the discal spot ; often 

 this white cloud is extended, and sometimes it reaches quite 

 across the wing to the dorsal margin ; hind margin dusted 

 with white, especially so toward the apex, and edged with 

 black dots; cilia shining dark grey. Hind wings broad, 

 rounded behind, very glossy, smokj'-grey or smoky-brown, 

 the nervures darker ; cilia of the same colour but tipped 

 with white. Female similar, but with thread-like antennae.- 



Underside of the fore wings shining dark smoke-colour, 

 -^vith a white costal spot before the apex. Hind wings 

 equally shining, slightly paler. Body dark brown. 



Variable in size, and also in the extent of whibe clouding 

 and dusting. 



On the wing from the end of May till the beginning of 

 August. 



Larva. — Head pale brown ; second segment with an un- 

 divided plate, slightly palar, its anterior edge straight, the 

 posterior convex ; on each side on the same segment is a 

 small reniform chitinous spot ; remaining segments semi- 

 transparent, greyish-white ; dorsal vessel dark grey ; anal 

 plate pale brown ; raised dots also pale brown, chitinous, 

 bearing a single hair. (Lord Walsingham.) 



Apparently feeding throughout the year — found in green 

 cones which were already considerably distorted, in July 

 nnd onward, and in the fallen cones in winter, becoming 

 full fed in May or June— therefore in all probability nearly
