6o LEPIDOPTERA. 



in which the margins of the hind wings were pale and 

 almost without markings ; in the collection of Mr. S. J. Capper 

 is one having the pupils of the eye-spots placed rather awry, 

 giving the expression of a squint ; another of a dark smoky- 

 grey with paler markings ; and others having the edges of 

 the eye-spots somewhat angulated ; in Mr. A. H. Clarke's 

 collection is a female, obtained at Tunbridge Wells, entirely 

 of a smoky-black with still blacker markings ; Mr. R. New- 

 stead reared, from a larva found in North Wales, a female of 

 a remarkably rich dark colour, with deep red stripes ; and a 

 somewhat similar specimen has been reared by Mr. W. 

 Holland in Oxfordshire. 



On the wing in April and the first half of May — rather 

 later, or even into June, in the North. 



Larva cylindrical, but with the segments deeply divided, 

 each being rounded, and crowned by a transverse row of con- 

 spicuously raised spots of large size, from each of which arise 

 a few stiff divergent bristles. Head rounded, deep green, 

 sometimes streaked with black ; body rich bright greeu, some- 

 times a little paler at the sides and with a vaguely indicated 

 spiracular pale stripe ; tubercles bright yellow, pink, or 

 purplish, ringed with black, either separate, or joined across 

 the back in rows by a black line, or situated in a broad trans- 

 verse black stripe ; legs and prolegs green. When full grown 

 a remarkably beautiful larva. When young black, and hairy 

 or bristly, with orange sjDiracular lines ; at about half growth, 

 black with dull orauge rings in which the black tubercles are 

 situated. Gradually as it grows and moults the orange rings 

 broaden, become dull yellow, brighter yellow, green, darker 

 and lighter, until the adult colour is assumed. Occasionally, 

 however, the black ground colour is maintained throughout. 

 Mr. C. W. Watts has found such specimens, full grown, but 

 deep black, with the usual bright coloured tubercles, among 

 those of ordinary colouring, near Belfast ; and others are on 

 record.
