Usually rather constant in colour in this country, but a

 S]iecimens reared by the Ilev. J. Hellins from the eggs of an 

 ordinary specimen taken in Sussex. Of these six, only one 

 approached in colour to the ]iarent, yet its ground colour 

 was more ochreous, and it had a black discal dot ; two others 

 were rather deeper ochreous, and also showed the discal spot, 

 the oblique stripe in one of them being rosy brown, and in 

 the other black-brown ; a fourth with an equally dark stripe 

 and the discal dot present, had the ground colour pale yellow 

 suffused witli smoky black ; the iifth had the ground colour 

 ochreous with a strong pink suffusion, the stripe purple-

 and tile sixth, also with shaded hind wings, liad the fore 

 wings yellow brilliantly sutt'used with rosy pink or crimson, 

 the oblique stripe crimson-brown, and tlie discal dot strongly 

 marked. In the collection of Mr. S. .I.(.'ap])er is a specimen 

 e(jually brightly suffused with rosy ])ink, the obli(|iie stripe 

 crimson, the discal spot absent, and the hind wings pure 

 white. It was captured by himself at a gas-lamp very
