of the leaves of the primrose. They are round, smooth, shining, 

 and of a pale yellowish green colour. 



The caterpillar is of an oval but depressed and elongated 

 shape; the head, rounded, heart-shaped, smooth, shining, and 

 of a bright ferruginous colour; the body is covered with rows 

 of tubercles: it is set Avith feathery hairs. On the hinder part 

 of the back there is a black dot on each joint, and on the 

 sides the like, but the spots less distinct. The general colour 

 is pale olive orange; underneath, it is whitish; the feet are 

 rusty brown; the claws whitish. It moves very slowly, rolls 

 itself up when disturbed, and remains in that state a long 

 time. Hubner says that it changes its skin five times before 

 going into the chrysalis state, and that each appearance varies 

 considerably. 



The chrysalis is suspended from the head, and is also kept 

 by a cord round its middle. 



The fifjure is from one of the specimens in mv own cabinet.
