legs attached to each segment of their bodies. Some kinds have 

 only a single pair of legs attached to each segment, while 

 others have two pairs. By this characteristic we are enabled 

 to separate, at a glance, the injurious from the beneficial; for 

 those which have only one pair of legs to each segment are 

 predaceous, feeding upon snails and other soft bodied-animals, 

 whereas those having two pairs of legs to each segment feed 

 upon vegetable matter. 



It is thus seen that true insects belong to the first Class, 

 which is known by the name of INSECTA. Having learned the 

 position which these animals respectively occupy in the Ani- 

 mal Kingdom, a short account will be given, in Chapters II., 

 III., IV., and VI., of the four states or stages through which 

 .insects pass, namely: First, the egg; second, the larva or 

 'caterpillar; third, the pupa, chrysalis, or nymph; fourth, the 

 perfect insect, or imago state. 



Chapter V. treats o^their transformations (metamorphoses).
