244 THE CLIFDEN NONPAREIL. 



head is greenish, with two frontal black crescents ; 

 the eighth segment having a dorsal protuberance of 

 a bluish-black colour, and marked with a few yellow 

 spots. On the ninth segment there is an oblique 

 black line extending to the hinder stigmata; the 

 latter are all surrounded with a black ring. It 

 spins a very loose cocoon among a few leaves, and 

 changes into a reddish-brown chrysalis, powdered 

 with pale blue, and having two small blue tubercler 

 on each side of the fourth and fifth segments. 



It is a rare insect in this country, and indigenous 

 specimens in good condition may still be regarded 

 as a valuable addition to a cabinet. It was first 

 figured by Wilkes as a British insect, and is said by 

 him to have been found at Cleifden, in Bucking- 

 hamshire; whence the English name he has as- 

 signed to it. It has since been observed in Suffolk, 

 Kent, Surrey, and a few other places ; the vicinity 

 of York is the most northern locality that has been 

 cited. In France, Germany, and other continental 

 countries, it occurs much more plentifully.
