pale bluish green color, somewhat resembling the peculiar 

 glaucous green hue of the leaf on which it feeds. It is gen-

 enjoys an unusual immunity ; so also the pear slug (Fig.

Returning again to the grasshoppers, the species of the 

 family of Locustarians, to which the Katydid belongs, are 

 modified for a life hidden among the leaves of trees. Nearly

 the grass, and are better protected from harm than the young 

 Acrydians, which are usually dark, though some are green.
