XX Report of the Entomologist. 



have obtained some Missouri gas tar to use on our trees which were 

 uninjured bj the New York product. 



A serious greenhouse pest, a little motli {Phlyctcenia ferrugalis) 

 whose caterpillar feeds upon the foliage of many greenhouse plants, 

 has been investigated bj a student, Mr. Franklin Sherman, Jr., and 

 his observations and results may be embodied in a bulletin soon. 



We are now investigating an apparently new insect pest of the 

 strawberry in this State. It is a leaf -roller, and it has done much 

 damage in at least one locality, ruining half the crop. We have 

 been successful in breeding the insect in the insectary and expect to 

 get our results ready for publication during the coming year. 



A bulletin on canker-worms, embodying the results of our inves- 

 tigations during the past two or three years, is in preparation. All 

 of the four or five kinds of canker-worms now at work in the State 

 will be fully illustrated in the bulletin. 



About 1,500 photographic negatives of injurious insects and their 

 work have been made at the insectary during the past ten years, and 

 this collection receives additions almost daily. These negatives 

 have furnished the excellent half-tone illustrations used in our bul- 

 letins, and we are now making a series of lantern slides, many of 

 them colored from life, for illustrating lectures at Farmers' Institutes 

 and similar meetings. 



The correspondence of the Division continues to increase, and 

 requires a large share of our time. We have attended during the 

 year several Farmers' Institutes and delivered addresses at the meet- 

 ings of the Western and of the Eastern New York Horticultural 

 Societies.
