REPORT OF THE STATE ENTOMOLOGIST 1902 153 
FAUNAL STUDIES 
A detailed study of the distribution of insects in New York 
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 deterniine 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 locality, 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 tle 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.
