the lower Hudson valley and Long Island, were likely to develop 

 later in the more northern sections and that hence the conditions 

 in one region could be used to indicate probabilities in others. The 

 fifteen Weekly digestsmot only recorded conditions in various sections 

 of the State and outlined preventive or remedial measures, but also 

 appraised the possibility of subsequent damage by various insects. 



Particular attention was paid to the possibilities of preventive or 

 early remedial work, and in carrying this out several circulars were 

 issued, especially one on fruit insects and crop pests, mailed May 

 30th, another discussing the destructive red bug and pear psylla 

 was issued June 2d, a third on spraying fruit trees with special 

 reference to the control of the codling moth was mailed June 7 th. 

 A circular calling attention to the work of the extraordinarily abun- 

 dant May or June beetles was issued June nth. One discussing 

 the seed corn maggot so destructive in the bean-growing regions 

 was prepared June 18th and the day outbreaks of the army worm 

 on Long Island were reported was marked by the preparation of a 

 circular calling attention to early indications of attack by this greatly 

 feared pest and giving in summarized form the more approved 

 control and remedial measures. The wheat midge injuring rye and 

 wheat, the midsummer leaf feeders of the apple orchard, the insect 

 pests of domestic animals and the Hessian fly were likewise discussed 

 in timely circulars. 



The correspondence reported above has been largely with county 

 representatives of the New York State Food Supply Commission. 

 Special effort was made to keep these persons thoroughly posted as 

 to the latest developments and the best methods of dealing with 

 various perplexing insect problems. These in turn have passed the 

 information along to their numerous correspondents and the effort 

 can not fail to have greatly increased interest in the problem of 

 insect control as well as promoted greater efficiency along these 

 lines. 



Gall insects. The Entomologist prepared an illustrated " Key to 

 American Gall Insects ' ' (now in press) which has resulted in much 

 interesting material being submitted for study. This is true of 

 the work of several gall wasps or cynipids, namely, the ribbed bud 

 gall and the white oak club gall, deformations which are occasion- 

 ally very abundant and injurious. Brief discussions of the work 

 and biology of these species appear in 'the Entomologist's report. 



There have been some exceptionally interesting gall midges sub- 

 mitted to the Entomologist for study, namely, a small collection
