124 LEPIDOI'TIZRA. 



exquisitely tiivj^ed with purple-red colour, which very rapidly 

 fades out. 



Verv constant iu colour and markings. Occasionally there 

 is a little variation iu the width of the central band ; Mr. 

 H. Goss has a specimen in which it is narrow and of quite 

 unusual shape, the portion near the costa being extraordinarily 

 slender; and 3Ir. Sydney Webb ])ossesses one in which the 

 band, narrowed and drawn nearer to the liase, is followed by 

 a beautiful stripe of pure white of more than twice the usual 

 width : continued also across the hind wings, and having the 

 uervnres most delicately indicated. 



On the wing in June and July, sometimes till the beginning 

 of August ; in confinement specimens of a very partial second 

 generation have been reared late in August. 



Lakv.\ tapering slightly towards the head; of a pale stone- 

 colour ; there is no regular dorsal line but a series of dusky 

 dashes and dots, and at the five middle segmental divisions 

 these dots become enlarged and (|uite black in colour, and 

 are preceded by an oblong transver.se reddish mark, and that 

 by a scjuare white spot ; there are two very wavy and 

 suffused snlidorsal lines of a faint dusky black, but just above 

 the spiracles is a clear thin line of the ground colour followed 

 by another of the darker tint ; spiracles l)lack ; under surface 

 rather more yellow than the ground colour, and marked on 

 each side of the five middle segmental divisions with little 

 groups of fine black dashes and dots. (Rev. J. llellins.) 



July and the beginning of August, on chickweed (Alsine 

 media) feeding up rapidly. 



TiPA light brown ; darker at the segmental divisions ; 

 head ijrominent ; wing cases clear trans])arent brown ; surface 

 roughened with numerous small depressions, except segments 

 nine and ten which are smooth and glossy ; anal segment 

 terminated by two short hooked bristles. In a cocoon of 

 loose silk mixed with fine grains of earth. (Miss M. Kimber.) 



In this condition through the winter.
