108 niGH-BBOWN FBITILLABT. 



marks near the tips are faded into rich brown, sometimes spotted with 

 silver. The hind wings are most beautifully variegated with buff, rich 

 ferruginous, and brown, the upper edge near the base being silver, 

 outside which are from five to seven large silver spots, these again 

 succeeded by an interrupted band of nine or ten still larger ones of 

 different sizes and shapes; these by a row of small rusty red spots, 

 some of which have their centres silver, and these again by another 

 row of seven triangular-shaped silver spangles. 



The caterpillar, in one of its first stages, is red, which is afterwards 

 exchanged for olive green, with a white line along the back, and 

 white spots on the sides. 



The chrysalis is of a reddish colour, with silvery spots. The insect 

 remains in the chrysalis state about a fortnight. 



A curious variety of this insect is mentioned by Mr. A. D. Michael, 

 as having been taken near Cromer, Norfolk, in which all the upper 

 side of the fore wings was of a deep brown colour without spots, but 

 with a lighter margin, in which were three or four darker lunules. 

 Other varieties have occurred in which the spots on the wings were 

 more or less confluent. 



The plate is from specimens in my own collection.
