LIST OF DRAGONFLIES TAKEN NEAR 
BUFFALO, N. Y. 
By E. P. Van Duzee. 
During the seasons of 1895 and 1896 I took up the collection of the 
local Neuropteroid insects as a recreation from the heavier work I had 
been doing on the Hemiptera. The time at my disposal was very lim¬ 
ited, only a few half-days during the summer, therefore it is not likely 
that this list, which enumerates 41 species, is anything like a fair repre¬ 
sentation of our local Odonat fauna. 
The principal localities mentioned are the following : Squaw Island 
and Black Rock Harbor, in Niagara River, are within the limits of Buf¬ 
falo City. Ridgeway, Ont., is on the north shore of Lake Erie, twelve 
miles west of Buffalo, and Point Abino is just beyond. Between these 
stations is a large swamp separated from the lakes by sand-dunes, reach¬ 
ing in places a height of 100 feet. About here is by far the best col¬ 
lecting grounds within many miles of Buffalo. Stations at Tonawanda 
and Amherst are on a deep stagnant creek which affords excellent breed¬ 
ing grounds for many of the Dragonflies. Colden and Boston are 20 
miles southeast from Buffalo, among hills about 600 feet in height, 
where the country is well wooded in places, and traversed by rapid 
streams. Lancaster, Elma and Hamburgh are on the level country, 
about 10 miles east and south from Buffalo. Clarence is farther east, 
and there and at Hamburgh are bog swamps that harbor many Odonata 
and other insects both interesting and distressing. 
Several interesting localities not far from Buffalo have not yet been 
visited for the Odonata. Among these is Niagara Falls, and it is not 
improbable that this and other places at Chippewa, the lower end of 
Grand Island, etc., will yield numbers of fine species not on this list. 
Two or three species from the upper end of Grand Island taken by Mr. 
Philip Fischer have been included to make this list more complete. 
For the determination of these Dragonflies I am indebted to the kind-
