each side of the fifth segment, and another erect tuft on the 

 last. On the back are four pairs of yellow tufts, shorter than 

 the others. It feeds on most trees and shrubs growing in 

 woods and gardens, even on the poisonous Cherry Laurel (or 

 laurel, as it is generally called in England), which very few 

 insects will touch. The cocoon is egg-shaped and yellowish- 

 grey, and the pupa is yellow with dark brown vv^ing-cases and 

 brownish hairs. 



When the female emerges she crawls about on the cocoon, 

 but never travels farther, laying her eggs upon it. Newman 

 says : " It is a very curious thing, and I believe hitherto un- 

 observed, and therefore unpublished, that these eggs do not 

 hatch all together like those of Moths in general, but come 

 out a few at a time, over a period of ten weeks, so that the 

 caterpillar, chrysalis, and Moths are all found together through- 

 out the summer and autumn."
