6 Insects of New York 



Pressure of other work later prevented Dr. Bradley from continuing 

 in charge, and the present editor was appointed in the spring of 1923, 

 while he was Acting State Entomologist at Albany, New York. The Board 

 of Editors was somewhat modified, for various reasons, and in the fall 

 of 1924 the work was transferred to Cornell University, where it was 

 completed under special appropriations by the New York State College of 

 Agriculture and the Heckscher Research Fund. To these funds the New 

 York Academy of Science added $150 and the New York Entomological 

 Society a like amount. 



It is impossible here to express thanks individually to the large number 

 of specialists and collectors, more than one hundred and fifty in all, 

 whose work has made it possible to gather together the data from the 

 great mass of published records and from specimens in public and private 

 collections. We believe we have been successful in transcribing by far the 

 greater part of these data, and no effort has been spared to include every- 

 thing. Such acknowledgment is made in the text and in the list of co- 

 operators beginning on page 1088. Special acknowledgment should be 

 made, however, for assistance in many ways, to the authorities and officers 

 of Cornell University, the American Museum of Natural History, the 

 Brooklyn Museum, the New York Academy of Science, the Staten Island 

 Institute of Arts and Sciences, the New York State Museum, Syracuse 

 University, the New York Entomological Society, the Brooklyn 

 Entomological Society, the United States Bureau of Entomology, and 

 the United States National Museum, 



The editor wishes to make particular acknowledgment to Professors 

 O. A. Johannsen and C. R. Crosby for supervision of the many details 

 in connection with seeing this publication through the press — a task to 

 which the editor has been unable to attend personally. The editor wishes 

 also to acknowledge with appreciation the painstaking efifort of Miss Lela 

 G. Gross, Assistant Editor of Publications at the New York State College 

 of Agriculture. She has been responsible for the selection of the various 

 kinds of type and for all other matters in connection with the mechanical 

 arrangement of the List, and in immediate charge of all corrections and 

 additions to the proof. Final typewritten copy was made by Mrs. H. M. 

 Fridley. Her intelligent and continued interest in what proved to be far 

 more than merely a clerical piece of work greatly facilitated its completion. 



Because of the studies made by certain specialists and the availability of 

 records in certain other groups besides insects, there have been included 

 lists of the following: the millipedes and centipedes, the spiders and har- 

 vestmen, the eriophyid mites, and the ticks. In all, 16,124 species and 

 varieties are included, of which 15,449 are insects. It is difficult to deter- 

 mine what percentage of the total number of species this figure represents. 

 In many parts of the State but little collecting has as yet been done and 

 many groups are still imperfectly known. It is not unlikely, therefore.
