PKEFACE 



This bulletin was prepared, first to bring prominently before the 

 public the very destructive nature of this imported insect, and 

 second to demonstrate that it can be controlled without great 

 expense, provided intelligent direction is given to the matter. 



The life-history and habits of this beetle have been given some- 

 what in detail because unless they are thoroughly understood, 

 it is very easy to adopt means that are only partially successful 

 or futile. In order to give the bulletin a more practical value, 

 short accounts have also been included of three other insects, 

 which, working with the elm-leaf beetle, have aided greatly in 

 ruining many noble elms. 



In the portion devoted to remedies prominence has been given 

 to the cost of spraying per tree, the proper apparatus and the 

 time and manner of application. It is surprising to see what mis- 

 takes some men make in dealing with insects and how they cling 

 to methods of no value. To offset this tendency, two of the more 

 common fallacies are mentioned and their futility shown.
