US large series of galls from which we were able to rear' a number 

 of previously unknown species. The care of this material devolved 

 largely upon Assistant D. B. Young, who has met with exceptional 

 success in rearing the flies. Miss Fanny T. Hartman has assisted 

 in caring for the biological material and has made excellent micro- 

 scopical mounts of many of these extremely delicate midges. 



Publications. Many brief, popular accounts dealing with in- 

 jurioius insects have been prepared by the Entomologist for the 

 agricultural and local press and a few notices of more than general 

 interest have been disseminated as press bulletins or through the 

 agency of the x^ssociated Press. A comprehensive popular bulletin 

 on the Control of Household Insects, made advisable by the recent 

 great advances in our knowledge of the relation of insects to the 

 dissemination of disease, was issued in May and is now, due to the 

 great demand for such information, practically out of print. The 

 report for last year, owing to delays incident to publication, 

 was not issued till the last of the present year. A popular 

 account summarizing one phase of our studies of gall midges 

 and entitled : " Gall Midges of the Goldenrod," appeared in 

 the Ottawa Naturalist for February. Biological data and brief 

 descriptions of nearly 50 reared species of Cecidomyiidae were 

 published in the issue of the Journal of Economic Entomology 

 for August. 



Collections. The additions to the collections have not been 

 very extensive, since the amount of material already at hand de- 

 mands the expenditure of much time before it can be properly 

 classified. Particularly gratifying additions have been made by 

 rearing large series of Caryomyia, Cincticornia and Sackenomyia, 

 the biology of these genera being previously unknown. There have 

 been valuable contributions of biological material, mostly insect 

 galls, through the generosity of Miss Cora H. Clarke of Boston, 

 Mass. 



The general work on the arrangement and classification of the 

 collection has been pushed as rapidly as pO'Ssible. Mr D. B. Young 

 has identfied practically all our species of Bombylidae, has done 

 considerable work upon the Empididae and made substantial prog- 

 ress in classifying the Sapromyzidae, the Tabanidae and the Sciomy- 

 zidae. Mr Young is also responsible in large measure for the 

 preparation of the list of insect types in the New York State col- 

 lection given on a following page. Much of Miss Hartman's time 

 has been devoted to the care of breeding material, to mounting and
