Gentlemen : I have the honor of presenting herewith my report on

General entomologic features. Excessive injuries by the forest 

 tent caterpillar, Clisiocampa disstria Hiibn. were even more 

 pronounced in many localities the present season than last year. On 

 account of this insect's appearing in force on many maples adorning 

 roadsides, the outbreak attracted more than the usual amount of atten- 

 tion and induced vigorous efforts in certain communities to prevent 

 serious injuries. The village authorities of Glens Falls, Saratoga Springs, 

 Herkimer and a few other places were obliged to fight the pest at public 

 expense. The closely related apple tree tent caterpillar, Clisio- 

 campa americana Fabr. was unusually destructive, specially in 

 the western part of the state. The appearance of a brood of 17 

 year cicadas, Cicada septendecim Linn, in the Cayuga lake 

 region excited considerable interest. Some attention, in an incidental 

 way, has been given to the distribution of certain insects believed 

 to be limited to the upper austral life zone. One of the most 

 important results of this work was to show that the 12 spotted asparagus 

 beetle, Crioceris 12-punctata Linn, was much more generally 

 distributed throughout the state than had been supposed. A personal 

 examination of sugar maples in Syracuse, Batavia and Leroy showed 

 that the sugar maple borer, Plagionotus speciosus Say, had
