The Orthoptera are vegetable feeders, and frequently commit 

 great ravages on various crops. They are divided into two groups, 

 viz., those which riui^ and those which jump or leap. We will begin 

 with those which run, which contains the Earwig {Forfcu/a), the 

 Cockroach {Blattd), the genus Mantis^ or Leaf Insects, and the
