DEPARTMENT OF ENTOMOLOGY. 



At the beginning of the year, nearly the entire support of the depart- 

 ment was assumed by the College of Agriculture. Under the present 

 arrangement, a part of the salary of the Professor of Entomology is paid 

 by Cornell University, and all other expenses of the department by the 

 New York State College of Agriculture. The writer therefore, includes 

 in this communication a report on all of the work of the department. 



Teaching Work. 

 All of the courses announced in the Program of Courses of Instruction 

 have been given, and have been well attended. The sum of the numbers 

 of students attending these courses during the past year is 378. Some 

 students attended more than one course. The numbers of different indi- 

 viduals were as follows :

Experiment and Research Work. 



Several members of the staff' of the department are engaged on the 

 I)reparation of text-books for the use of students and general readers. 

 These include a manual of the spiders of the United States, a book 

 on insects injurious to fruits, a work consisting of tables for the iden- 

 tification of the insects of the Northeastern United States, a text-book 

 on Insect Morphology, and a text-book of General Biology; and there 

 was published during the year by Assistant Bradley a monograph of 

 the Evaniidae. 



Professor Needham is devoting nearly his entire time to research, 

 a large part of which is concerned with insects and Crustacea that 

 serve as the food of fishes ; this research is supported by private funds, 

 but is conducted at the field station of the college in the Renwick 

 marsh near Ithaca. 



Professor Slingerland is devoting considerable time to studies of 

 injurious insects, and Mr. Crosby is devoting his entire time to re- 

 search in this field. During the last year, the following subjects were 

 investigated : 



(a) A study of the habits and life-history of the timothy joint-worm 

 and other Isosomas infesting grains and grasses, with a view to devising 

 a method to prevent the injury caused by these insects. 



(b) A study of the habits and life-history of the apple-seed chalcis, 

 grape-seed chalcis, and four other seed infecting chalcid-flies.
