about six small triangular spots, blackening at tbe posterior 

 margin. 



Caterpillar. Velvetty black, with short white and tawny 

 hairs, the last forming on each side of the body a line of the 

 same colour. 



Chrysalis. Lemon colour, sometimes whitish with nume- 

 rous black spots and streaks. 



OhscrmUion. The lorvse of P. Craltegi, enclose themselves 

 in the autumn in cases of silk, and thus pass the cold season 

 in small societies of irom two to twelve, under a covering 

 formed of leaves. When first excluded, they devour the 

 shells of the eggs from which they have proceeded. The 

 female is very prolific, and covers her eggs which she deposits 

 on the extremity of a hawtliom branch, with a coating of 

 varnish so effectually weather-proof, that they remain in 

 security till the larva are excluded. The Butterfly of this 

 species as well as of f'anessa Vrlicie and Polycliloros, emits a 

 fluid of a reddish colour, which has frequently given rise to 

 the reports of showers of blood which are said to have fallen 

 in diflerent places. This species is stated to have disappeared 

 from the neighbonrhood of London for many years.
