64 LEPIDOPTERA. 



parallel with the hind margin till it reaches the curved stripe, 

 which it crosses and then bends sharply back to the costa 

 where it also is thickened. Hind margin from the tip down 

 the concave portion strongly edged with black-brown, and 

 inside this with bluish grey, lower portion reddish brown ; 

 cilia short, pale brown. Hind wings ample, rounded behind ; 

 pale brown, costal region broadly paler ; from the dorsal 

 margin arise four very slender indented brown lines, corre- 

 sponding with those of the fore wings but extending only 

 across a portion of the wings ; just before the hind margin is 

 another, even more slender, dotted on the nervures and 

 zigzagged between them, but extending from margin to 

 margin ; outside this the hind margin is sharply edged with 

 bright brown ; cilia paler brown. Female rather larger ; an- 

 tenu£e distinctly though very shortly pectinated ; hind wings 

 paler with the costal region whitish ; otherwise similar. 



Underside bright light brown ; shading to deeper brown 

 at the apex of the fore wings ; beyond the middle are two 

 curved transverse brown lines, those in the hind wings much 

 scalloped ; nervures brown ; at the apex of the discal cell in 

 the fore wings are two indistinct purplish brown spots. In 

 the female paler, but showing the sub-marginal dark lines of 

 the upper side, legs short, neat, not tufted, light brown ; 

 body very pale brown. 



Variation is usually very slight, merely existing in the 

 depth of the brown ground colour and distinctness of the 

 transverse lines ; but occasionally in the North of England, 

 and more constantly in Scotland, is found, in company with 

 the typical form, one in which the ground colour, in both 

 sexes, is brownish white, in many cases very nearly white ; in 

 some of these the transverse lines near the base of the fore 

 wings are very indistinct, while in others they are sharply 

 accentuated, but on the underside the marginal markings 

 are visible in both sexes. This whitish form is even, very 

 rarely, found in the South of England. Mr. F. J. Hanbury 

 possesses one taken in Essex. In the collection of Mr.
