Insects of New York 7 



that more intensive collecting and study should increase the present total 

 by at least 25 per cent. It is hoped that the present list will increase both 

 the number of collectors and the number of workers, and will stimulate 

 further study along this line. 



The name of a collector or its abbreviation is indicated by the use of 

 italics, thus — Ndni ; that of the person responsible for a determination 

 or as having supplied a record is placed in parentheses, thus — (Ndm) ; 

 italics in parentheses indicate that the same person is both collector and 

 determiner, thus — {Ndm). Where the determiner is unknown the loca- 

 tion of the material upon which the record is based is often given, and 

 occasionally both determiner and location are indicated in parentheses ; 

 for example, (Vdyk CU), (VdykCU), or (Vdyk-CU), means deter- 

 mination by Van Dyke of specimens in the Cornell University collection. 



The data in connection with each locality are separated by semicolons. 

 Staten Island and Long Island localities come after a colon following 

 SI and LI in bold-faced type. 



Owing to a misunderstanding on t;,he part of one of our editors, the 

 species numbers which are used in the Hemiptera and the Coleoptera 

 were omitted from the manuscript in some cases. It was thought that 

 the slight inconvenience which might result from these omissions would 

 not be sufficient to warrant the expense which would have been involved 

 in making the corrections in the proof, and therefore the numbers are 

 missing in these cases. 



FAUNAL DISTRICTS 

 W. T. M. Forbes 



For convenience in indicating localities, the State of New York may 

 be divided into the districts shown on the accompanying map. They are 

 distinguished partly by climate, but more by topography and geological 

 substrata; and they are laid out with but little reference to life zones. 

 The Adirondack, Appalachian, and Taconic districts, the Tug Hill plateau, 

 and the small area of the New Jersey Highlands which extends into the 

 State, represent the higher country, the intervening districts being the 

 plains and the broader river bottoms. The Coastal Plain is represented by 

 Staten Island and Long Island. 



The St. Lawrence Plain is a broad open valley so far as New York 

 is concerned, while on the Canadian side it is continuous with the broad 

 St. Lawrence Plain of that region. Because of the northern latitude the 

 climate represents the Transition zone, though the altitude is only a little 

 above sea level. Relatively little collecting has been done here, the 

 most important localities being perhaps Waddington and Ogdensburg near 

 the northern boundary of the State, and Clayton near the mouth of Lake 

 Ontario. 



The Adirondack district comprises a great plateau of from 1500 to 1800 

 feet elevation, cut with valleys which are as a rule too narrow to shelter
