DEPARTMENT OF ENTOMOLOGY 157 



DEPAETMEXT OF ENTO^ilOLOGY 



The work of the department of entomology during the year 

 lias followed closely along the lines of previous years. Eealiz- 

 ing that the only way to obtain results of permanent value is 

 to work continually and exhaustively upon the subjects selected 

 for study, I have continued to confine our efforts to a com- 

 paratively few problems. 



Two bulletins have been published by this department dur- 

 ing the year. In April, Bulletin Xo. G4:, treating of the Forest 

 Tent Caterpillar, was issued to spread abroad a knowledge of 

 this insect, which became exceedingly destructive in May and 

 June. The October Bulletin (Xo. 67), treating of the Spiny 

 Elm Caterpillar, was published to enlighten those interested 

 concerning the life-history of, and remedies to be used against, 

 this pest. 



So much material has accumulated for the Insect Record of 

 the year that it has been thought advisable to issue it as a sep- 

 arate bulletin rather than to incorporate it with this report, as 

 jias been done heretofore. A second bulletin upon the Forest 

 caterpillar is also being prepared for publication this winter. 



Studies of the life-history and parasites of both species of 

 Tent Caterpillars have been continued through the season, as 

 have the studies of several other injurious species, especially 

 the Spiny Elm Caterpillar, the larva of the Mourning Cloak or 

 Antiopa butterfly. With the assistance of Mr. Xed Dearborn, 

 stu-dies of the food of birds have also been continued, the spe- 

 cies receiving special attention being the Euffed Grouse, or 

 ^'Partridge," and the Yellow-rumped Warbler. In the insect 

 work I have had regularly the valued assistance of Mr. W. F. 

 Fiske, and during the summer vacation Mr. R. A. Cushman 

 added a large number of specimens to the insect collection. 

 Most of the drawings for the entomological bulletins have been 



made by Mr. Joseph Bridgham.
