Bignell. They are not so large as normal specimens, and the 

 inner edge of the black band is less indented. A beautiful 

 male, in which the black band is thickly obscured by orange 

 scales, is in Mr. C. A. Briggs's collection ; also a white female, 

 which has even the central spot of the hind wings wliite ; one 

 with white fore wings only ; another with one yellow hind 

 win", and the other suffused with brown ; and a white female, 

 in which the marginal pale spots are duplicated, and so large 

 as to break up the black baud of the fore wings. Mr. Boyd 

 has a specimen in which the usual black discal spot is yellow 

 edged with black. Specimens are known of a brownish- 

 orange or with smoky blotches in the fore wings, and, very 

 rarely, gynandromorphous examples occur. One of these is 

 in Mr. S. Stevens' collection. It is, in fact, almost impossible 

 to enumerate the aberrations of this species. 



Time of appearance usually August and beginning of 

 September, but on one occasion Messrs. Webb and Goss found 

 it emerging freely at the end of September and beginning of 

 October, when the commencement of frosty nights appeared 

 in some cases to hinder the full development of the colour, 

 and gave the specimens a greasy, smooth look. On another 

 occasion, in 1877, 1 found freshly emerged specimens in South 

 Wales as early as June Ith. They were tlie finest I have ever 

 met with, and considerably larger than those of the later 

 brood. 



Larva deep grass-green, with minute black dots ; spira- 

 cular line yellow or whitish, with a pink blotch under a 

 black spot on each segment. Feeding upon clover, lucerne, 

 Lotus corniculatus., Mdilotus, and other L«juminosa\ 



Pupa moderately stout, pointed in front of the head and 

 with long wing sheaths. Yellowish-green, with richer green 

 wing cases, and a yellow line on each side. On leaves or 

 stems of the food plant, or other convenient places close to 

 the ground. 



This beautiful insect is, perhaps, of all our species the most
