42 LEPIDOPTERA. 



the second stripe of the fore wings strongly marked, brown ; 

 tind wings rich 3'ellow, shading to white at the dorsal 

 margin ; the central spot and cross stripe rich purple-brown 

 and strongly accentuated. Body yellow-brown ; legs more 

 tinged with pale purple-brown. 



Rather variable in the shade of yellow of the fore wings 

 and in the distinctness of the markings, which sometimes 

 are suffused with yellow. In the collection of the late Mr. 

 r. Bond are two males having these wings quite unicolorous 

 yellow. Mr. Frank Norgate has a male in which the whole 

 basal space of the fore wings to the first line is suffused with 

 pale purple, and the outer stripe is extremely broad and 

 strongly marked ; and also a female in which the two stripes 

 are so curved as to meet on the dorsal margin, and form, 

 between them, a distinct angle. 



In Mr. Sydney Webb's collection are specimens of which 

 the fore and hind wings are strongly tinged with smoky 

 colouring, and the stripes of a leaden-purple ; also a large 

 female which has the fore wings strongly dotted with purple- 

 brown and the stripes deeply marked in the same colour. 



On the wing in May and June, but in Southern Counties 

 sometimes at the end of April; a second generation apj)ears 

 in August and the l)eginning of September. 



Larva. Head a little narrower than the body, rather 

 notched on the crown, putty-coloured, the lobes slightly 

 tumid ; body of uniform substance throughout, without 

 humps, but having the skin delicately shagreened ; there is a 

 manifest skin-fold on each side, and the skin is also trans- 

 versely wrinkled ; the thirteenth segment has, below the anal 

 flap, two long, conical, acute points directed backward ; body 

 putty-colour with numerous narrow, waved, longitudinal 

 stripes of a darker tint ; of these the more conspicuous are 

 five in number, and approximate, constituting a dorsal orna- 

 mentation ; the middle one, double during a part of its 

 course, is more conspicuous and darker coloured towards the
