TEE CLIFDEN NONPAREIL. 
head is greenish, with two frontal black crescents ; 
the eighth segment haling 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 smTounded 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 tw'o small blue tubercles 
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 SuflTolk, 
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.
