The Caterpillars of this Moth feed on the White and Black Thorn, 

 together with feveral herbaceous plants ; it has been obferved to thrive 

 better in the breeding cage when regularly fupplied with frefh grafs, 

 to keep the former in a proper ftate of moifture. 



The Female depofits her eggs in June or July, the Caterpillars are 

 hatched in Autumn, and remain in that ftate during the Winter; 

 about the middle of May it fpins a large brown cafe, within which it 

 paries to the Pupa ftate ; the Moths appear in June. 



In the Caterpillar ftate it is fcarcely pofllble to difiinguifh the Male 

 from the Female, except that the former is fmaller than the latter; but, 

 in the laft ftate their colours are entirely different, the Female bein«- 

 of a pale yellowifh teint, inclining to fox colour, the Male is of a 

 rich brown. 



The Eggs are very curious, they refemble in fhape thofe of a Hen, 

 but are neatly mottled with dark brown. 



The Caterpillars caft their fkins feveral times, and always thereby 

 affume a new appearance, though the general colours and chara&er of 

 the fpecies may be traced through every fhge. Our figure is copied 

 from a very large and fine coloured fpecimen of the Female, that 

 was met with at Darent-Wood^ Dartford.
