white ; tufts smtiU, white. Fore wings broadly trigonate ; 

 costa gently arched ; apex bluntly angulated, almost rounded; 

 hind margin evenly and slightly curved; dorsal margin also 

 a little filled out ; greyish-white, regularly crossed by 

 numerous undulating pale brown lines and stripes, each of 

 which arises from a blacker cloudy spot on the costa, and is 

 also more distinct ou the dorsal margin ; first and second 

 lines rather unusually near together, each blackened and 

 rather streaked on the principal nervures, and each attended 

 outwardly by an obscure brown stripe into which the blacken- 

 ing of the nervures runs; between them is no darker lantl 

 whatever, but often a slender, more angulated and irregular, 

 brownish-black line; in the hinder area between some of the 

 slender transverse lines are two series of faint spots of the 

 white ground colour, separated by indistinct darker longi- 

 tudinal shades, the outer of these seems to repi-esent the 

 subterminal line ; extreme liind margin edged with black 

 lunules ; cilia white. Hind wings rather elongated, rounded 

 behind, white, with the nervures, here and there, and the 

 cross-bar, tinged with brown, and two faint rippled brownish 

 lines forming a submarginal shade ; hind margin streaked 

 with black ; cilia white. Female very similar, but with 

 simple antenna^, and a shorter body. 



Underside of the fore wings dull pale brownish-grey, rather 

 rippled with faint yellow stripes, and more tinged with yellow 

 on the costa. Hind wings white, with a small black central 

 spot, and three or four faint, curved and rippled, brown 

 transverse lines. Body and legs pa'e brown. 



Rather variable in the depth of colour of tln' transvei-se 

 stripes and lines of the fore wings, and even in their number, 

 some specimens having the spaces between the first and 

 second lines, and outside the second, almost without markings, 

 and forming white bands; while others have these portions 

 as fully ornamented as the rest ; also every intermediate 

 stage occurs. In South Yorkshire a local recurrent form 

 seems to have quite recently made its appearance. In it the
