Several bulletins. 



Dr. Packard has continued work on the Report on Forest Insects. 

 He spent a portion of March and April in Northern and Central 

 Florida studying and collecting the species injurious to Live and 

 Water Oak, as well as to the Pines and Cypress. His observations 

 go to corroborate those of others who have studied the Florida insect 

 fauna, viz, that while a large proportion of the insects feeding on 

 the oaks in Central Florida differ from those found in the Northern 

 States, yet the pine insects from Maine to Florida belong to nearly 

 one and the same fauna. During the summer months he worked in 

 Maine, on the shores of Casco Bay, and a considerable amount of 

 work was also done near Jackson, in New Hampshire, and around 

 Providence. A report by him on some of the insects observed, and 

 especially on a worm injurious to spruce buds, has been submitted, 

 and will be published in the next bulletin. 



Mr. F. M. Webster has continued investigations on the insects 

 affecting our grains and forage plants, and his report, included here- 

 with, contains a number of interesting observations, and also a list 

 of 102 species of insects frequenting Buckwheat, with notes of their 

 relative abundance and their method of attacking the plant. 



Mr. Lawrence Bruner has continued work in Nebraska, and a 

 special report from him will be published in bulletin form. 



Prof. Herbert Osborn, of Ames, Iowa, has continued to assist me 

 in work upon the insect parasites of domestic animals. 



Miss M. E. Murtfeldt and Mr. J. G. Barlow were each engaged 

 during the year for brief periods in various observations in Missouri, 

 and Mr. William H. Ashmead similarly for a brief period in Florida. 



Work by Mr. B. P. Mann on the Bibliography of Economic Ento- 

 mology has been interrupted by the reduction in the appropriation, 

 but otherwise the Divisional force at the Depariment remains the 

 same, Messrs. E. A. Schwarz and Theo. Pergande assisting in the office 

 work. 



_ The illustrations to this report have been made by Miss Lillie Sul- 

 livan and Dr. George Marx, with the supervision of myself or of 

 Mr. Howard. 



I take pleasure, in conclusion, in acknowledging my indebtedness 

 to Mr. Otto Lugger for assistance in the preparation of the article on 

 the Buffalo Gnats and for the satisfactory manner in which he carried 

 on his observations at Memphis, and particularly to Mr. L. O. How- 

 ard, who has had charge of the Division during my absence, and who 

 has materially assisted me throughout both in the office correspond- 

 ence and the preparation of reports. December 24, 1886. 



Respectfully submitted, 



C. V. RILEY, 



Hon. Norman J. Colman, Entomologist.
