red, blotches or clouds which lie upon the costa, and are very 

 irregular in form and size ; towards the apex of the wing is a 

 more definite prostrate triangle of the same colour ; cilia 

 yellow, dotted with chocolate. Hind wings rounded behind ; 

 sulphur-yellow ; central spot obscurely pale grey, followed 

 by a most indistinct, and often fragmentary, irregular, central 

 transverse line ; cilia yellow, spotted and clouded with choco- 

 late. Female very similar, a little stouter, often larger, and 

 with the transverse markings more visible. 



Underside light yellow, with the central spot of all the 

 wings, and a slender curved transverse line towards the hind 

 margin, dark chocolate; a pale chocolate stripe lies along the 

 costa of the fore wings, thickened and then tapered off 

 towards the apex ; cilia spotted with chocolate ; legs of the 

 same colour, untufted ; body pale yellow. 



Usually very constant in colour and markings — such as 

 they are — but occasional sjaecimens have the transverse lines 

 very prettily and distinctly rippled in crescents between the 

 nervures, and much more rarely these ripples give rise to 

 longitudinal dashes of the same semi-transparent grejnsh 

 shade. Two such — male and female — are in the collection 

 of Mr. Sydney Webb. Another of his specimens is quite 

 white, having no trace of the usual yellow colour, and a very 

 lovely example of this form is in the cabinet of the Kev. 

 Joseph Greene. Mr. S. J. Capper has another such, and also 

 a yellow specimen in which the chocolate costal blotches have 

 ran together into a complete costal stripe. Variation in 

 this direction, though in a less complete degree, is not very 

 rare, as also in the absence of these spots, specimens wholly 

 yellow being found in Somerset and other western counties. 

 A specimen having the fore wings white is in Mr. P.M. Bright's 

 collection, and I remember the exhibition by Dr. R. Freer 

 at the Birmingham Entomological Society of a beautiful 

 example, taken in Staffordshire, of a rich orange yellow, with 

 a deeper shade of the same along the costa. A supposed 

 aberration, occasionally to be seen in collections, has long
