THE INSECT WORLD. 



Brown Argus (Fig. 156), which does not occur here; the Lyccena 

 {Folyotnmatiis) cEgaii, which flies about our sandy heaths. 



Fig. 155. — Lycsena (Polyommatus) Corydon. 



The caterpillars of this genus, as also those of the preceding, are 

 broad and flat, resembling wood-lice, with very short legs, and are 

 very slow in their movements. 



Fig. 156.— Lycitna (Polyommatus) battus. 



Fig. 157. — Lycaena (Polyommatus) aegon. 



In the numerous family of the Vanessidce are placed the beautiful 



species known as the large and small Tortoise-shell, the Peacock, &c. 



The large Tortoise-shell Butterfly {Vaiiessa polychloros, Fig. 158) 



genus named in the text Polyommatus and that called Lycctna are never considered 

 Identical. When either name is applied to the one, it is not at the same time 

 applied to the other.— Ed.
