THIRD REPORT OF THE DIRECTOR I906 69 



Mr J. R. Gillett, a medical student, was engaged during the entire 

 summer in making some 2000 microscopic preparations of these in- 

 sects. These large additions to our collection will result in 

 important contributions to our knowledge of this hitherto rela- 

 tively unknown group. The value of this work has been greatly 

 increased by the enthusiastic and intelligent collecting of Assistant 

 Entomologist Young and Assistant Nixon. 



Publications. The Entomologist has contributed numerous 

 economic articles to the agricultural and local press. The report 

 of the office for 1904, owing to delays, did not appear till early in 

 the present fiscal year, and that for 1905 was not issued until Sep- 

 tember, 1906. A special bulletin giving a summary account of the 

 gipsy and brown tail moths [Mus. bul. 103] was issued in mid- 

 summer, and the first volume of Insects Affecting Park and Wood- 

 land Trees [Mus. mem. 8] appeared in February; the second 

 volume of this work will appear without delay. 



Another paper entitled Diversities among New York Mosquitos 

 was reprinted from the Yearbook for 1904-5 of the American 

 Mosquito Extermination Society. 



Collections. Considerable additions have been made to the 

 State collections aside from those secured in prosecuting the special 

 investigations mentioned above. A fine collection of parasitic wasps 

 (Chrysididae) was "received from A. Mocsary, Budapest, and a 

 valuable addition to the Tachina flies from Dr Mario Bezzi of 

 Torino, Italy. Some desirable mosquitos from the south and south- 

 western part of this country, from Jamaica and the Philippine 

 Islands were obtained through various correspondents of the office. 



The special collections made by the members of the office staff 

 in the Cecidomyiidae, mentioned above, have resulted in large addi- 

 tions to this group. The work upon the State collections has 

 continued with unabated vigor and the general condition of the 

 collections has been much improved, particularly in the families 

 Ortalidae, Trypetidae, Dolichopodidae and Ephydridae, The rep- 

 resentatives of the latter groups have been determined by the Assist- 

 ant Entomologist. The midges (Chironomidae) have received 

 considerable study at the hands of Assistant I. L. Nixon, who has 

 also devoted much time to the general arrangement and classifica- 

 tion of the Coleoptera.
