REPORT OP THE STATE ENTOMOLOGIST 1902 153 



FAUNAL STUDIES 

 A detailed study of the distribution of insects in New ^ork 

 State, or, for that matter, in any section where there is some 

 variety in climate and physical characteristics, is bound to result 

 in some interesting discoveries regarding the factors limiting the 

 presence of various species. This is a matter of considerable 

 importance, since it has a practical application in enabling us 

 to determine in a measure the limits beyond which some of our 

 very destructive, introduced species can not spread. The collec- 

 tion of my assistant, Mr Young, listed below, has been made in 

 an exceptionally rich locality, where there is more or less ming- 

 ling of boreal and austral forms. Over 700 species are represented 

 in the list, to which we expect large additions will be made in 

 the future. It is published at this time, not only to make the 

 data available, but also in the hopes that other entomologists 

 in that locality may be encouraged to continue the work. 



LIST OF COLEOPTERA TAKEN AT NEWPORT, HERKIMER CO N Y. 



BY D. B. YOUNG 



We have had lists from the western and southeastern parts of 

 the State of New York and the Adirondacks, but none so far, 

 to our knowledge, from the central portion of the State. The 

 object of this list is threefold, partially to fill the gap, to call 

 the attention of collectors and others to a much neglected field, 

 and to show the result of five years' continuous collecting in a 

 single restricted localitj^, restricted in that this section is almost 

 destitute of pine, spruce, balsam and oak. Therefore, it will be 

 noticed that many of the forms found about these trees, only a 

 day's drive to the north, are absent from this list. 



Our thanks are due to Mr Charles Liebeck of Philadelphia Pa. 

 for his kindness in determining quite a large number of the 

 beetles.
