VZ6 SILVER-WASHED FRITTLLARY. 



shew through, and of others only the outlines; those towards 

 the outer edge of the wing are nearly obliterated. The hind 

 wings are pale metallic green, with two short waves of silver 

 near the base, a third tinged with purple running across the 

 wing, and another still more tinged with purple follows the 

 margin; between these two last is a row of darker green spots, 

 with lighter centres, and another of green half-moons, the 

 latter outermost. 



The female is larger than the male, without streaks, the spots 

 larger, the fulvous colour less bright, and tinged with green. 



The caterpillar is light brown, with a row of yellow spots 

 on the back; it is covered with long spines, the two next the 

 head being longer than the rest. 



The chrysalis is described as being grey, with gilt tubercles. 



One variety, a female, taken by J. C Dale, Esq., has the 

 upper surface of the wings very dark, with some whitish spots 

 at the tips of the fore wings. 



In one, figured by Hubner, the wings on the right hand 

 side are of this variety, a,nd those on the left as in the ordinary 

 specimens. 



Mr. Westwood adds, "A still more remarkable specimen has 

 been figured by M. Wesmael, in the fourth volume of the 

 Bulletin of the Academy of Brussels, in which the right wings 

 were those of the male type, except that the marginal row of 

 spots were as large as in the female; the left fore wing 

 exhibited a complete 'melange' of the male and female, as well 

 as of the variety and typical individuals, the ground colour 

 being fulvous, as in the male, but the markings, especially at 

 the tip, dark as in the female, with the white spots of the 

 variety; upper side of the hind wings entirely coloured as in 

 the variety." 



Another specimen of this kind is mentioned by Ochsenheimer, 

 the right wings of which were those of a male, and the left 

 those of a female. 



In Loudon's "Magazine of Natural History" the occurrence 

 of a similar one in England is noticed. 



The engraving is from specimens in my own cabinet.
