The Honorable Commissioner of Agriculture, Albany, 



Sir : — The following paper considers another of the many 

 insects which contribute their share towards making fruit-growing 

 a scientific business. The observation of any insect and the 

 study of truthful descriptions of it, are direct means of education ; 

 and the final mastery of it is a means of encouraging and fortify- 

 ing the farmer in every adversity. This bulletin, therefore, has 

 two distinct merits, — the imparting of immediate information 

 concerning the pest, and the power of inspiring correct and hope- 

 ful habits of thought ; it is therefore submitted for publication 

 under Chapter 437 of the law designed to extend the experiment 



station method and work.
