Uuderside of the fove Swings smoky-grey ; costa whiter, 

 hut barred beyond the middle with black ; discal spot visible 

 as an erect black streak ; cilia sharply dotted with white. 

 Hind wings dusky white, thickly dusted with brown ; cilia 

 along the apical portion dotted with white. Body and legs 

 ashy-grey ; tarsi dark brown. 



There is considerable variation in size in both sexes, in 

 many instances specimens of the autumn emergence being 

 small. These also are rather liable to partial approximation 

 of the stripes of the first and second lines, so as to form a 

 dark central band. This however is not confined to the 

 second brood ; Mr. 11. Adkin possesses a very large example 

 in which these two stripes are enlarged, and united from the 

 dorsal margin to the middle, thus forming a conspicuous 

 forked central band. IMr. Sydney \Vebb possesses a large 

 specimen in which the central band, equally dark, is formed by 

 a filling in of dark grey between the two stripes ; another, in 

 the late Mr. F. Bond's collection, has a very rich liand formed 

 by the coale.scing of the stripes, while their colour is changed 

 to dark brown and black, the rest of the fore wings shaded 

 with light brown, and the pale spaces rippled with numerous 

 fine brown lines, altogether a most wonderful creature. 

 Another remarkable specimen, in the collection of Mr. S. J. 

 Capper, has the space between the two stripes broad, and 

 filled up with light brown, and the apical obli(iue dash formed 

 of chestnut clouds. In the opposite direction there seems to 

 be a local tendency to obliteration of the stripes, some of 

 those from Kent having a verj' obscure appearance, and one 

 in the collection of Mr. F. -). 1! anbury, of a pale shade of 

 grey, being almost devoid of them, in Ireland some speci- 

 mens have the ground colour white, or nearly so. 



On the wing in May and .lune, and as a second generation 

 from the end of -July till September. 



Lauva elongated, moderately stout, slightly tapering 

 smaller to the head, which is decidedly less than the second
