Prefatory Statement. 



The publication of this volume by the State of New Jersey, at this 

 time, marks an era in the progress of the study of entomology, and 

 also shows how extensive the depredations of injurious insects have 

 become. So extensive, indeed, as to require a large annual expendi- 

 ture of time and money on the part of the farmer to overcome them ; 

 and also the necessity there is for study of this subject, not only by 

 those who are or expect to become farmers, but by every one who 

 expects to grow fruit-tree or vine, shade-tree or flower, as no plant 

 or tree is exempt from the ravages of some insect pest. 



To make this work of greatest use, the Executive Committee of the 

 State Board of Agriculture have decided to send a copy to every 

 school teacher in the State of New Jersey who applies for it. Such 

 copy to be used by the scholars, under direction of the teacher, for 

 study and reference. The secretary of the various farmers' organiza- 

 tions throughout the State will be supplied with a copy for use by the 

 members, and any family desiring a copy for study will be supplied 

 on request, so long as the edition lasts. 



The Executive Committee hereby express their thanks to the 

 State Printing Board for granting their request to print this work, 

 believing that its study will be of much benefit to the fruit and agri- 

 cultural interests of the State. 



Requests for copies should be addressed to 



Franklin Dye, Secretary,
