its classifícation and relationship to other destructive locusts ol 

 various parts of the world, the following pages will be dev'oted 

 to giving an account of its life-history and habits. In doing this 

 we must, of course, be more or less restricted to what has 

 been ascertained from actual personal observations during the 

 past eight or nine months. To this information, it is true, there 

 must be added a great deal obtained from published accounts, 

 as well as reports from numerous correspondents. This account 

 ot the insect's life-history and habits is of great importance, 

 since upon this knowledge must be based the various recom- 

 mendations for its suhiuaation and destruction.
