dotted with wliite. Hind wings elongated, the hind margin 

 sinuous; colour pale purple, interrupted in the middle by a 

 broad j>ale yellow transverse band, in which are parallel 

 purplish-brown lines ; cilia shining white. Female similar. 



Underside of the fore wings similar to the upper, so far as 

 the discal spot, costal dots, and second line are concerned, 

 but more strikingly shown ; middle area smoky-purple ; 

 dorsal area white ; the cilia as on the upper side. Hind 

 wings smoky-white with black dusting, the hiud-marginal 

 region purple ; near the base is a transverse black line, and 

 in the middle a double one. Body and legs pale purple- 

 brown. 



Rather variable in colour. Specimens taken at Folkestone, 

 Kent, are sometimes of (|uite a different tone in this 

 respect, all the usual purple or crimson purple areas on fore 

 and hind wings being of a silky purple-^?'«y ; on the other 

 hand some of those taken near London are of very light 

 yellowish-purple ; and one, in the cabinet of Mr. A. F. 

 Griffiths, is yellow, the markings remaining normal. Almost 

 all intermediate dark and light shades occur. 



On the wing from the end of June till the beginning of 

 August. 



Larva rather slender to the sixth segment, thence 

 gradually thickening to the ninth and as gently decreasing 

 to the end of the eleventh, thence more tapering ; head 

 narrow, dark brownish-red, body segments divided by tico 

 deep wrinldes very dose together, which is a distinguishing 

 character from a very early stage ; dorsal plate blackish- 

 brown ; body chocolate-brown above, dingj' pink or brownish- 

 ochreous beneath ; anal plate edged in front and on the 

 sides with dull black ; legs pale gn^yish-drab ; prolegs 

 similar, the anal pair extended. (W. Buckler, con-
