June, i8 97 .] Van Duzee: Dragonflies near Buffalo, N. Y. 89 
cover the shallow water. It it also common along all of our inland 
streams and ponds. Here they have been taken from May to Septem¬ 
ber. The orange females appear to be more abundant than the blue. 
Anomalagrion hastatum Say. Two males captured among the 
rushes on the shore of Lake Erie at Point Abino, August 8, 1896. The 
smallest of these expands but 20 mm. 
Gomphus spicatus Selys. Taken in a tamarack swamp at Clarence 
in July, and rarely about Black Rock Harbor, in June. 
Gomphus fraternus Say. Abundant along Niagara River in June. 
I have taken it only about still water. 
Gomphus villosipes Selys. Taken on Grand Island, in Niagara 
River, by Mr. Philip Fischer, of this city. 
Epiasschna heros Fab. Common. June and July. I can 
verify Dr. Kellicott’s remark that this species seems to enter our houses 
from choice. 
Boyeria (formerly Fonscolombia) vinosa Say. One example 
of this interesting species was taken by me from a bush in deep woods 
far up on a hillside at Colden, N. Y., August nth, 1896. A little 
water run was near, represented then by an occasional pool, and here 
may have been the home of the larva. 
Aeschna constricta Say. August and September. Taken im¬ 
mature in July. I have found this species most commonly in hilly 
country where a small brook meanders through open woods and pasture 
lands. In such places it is sometimes abundant. On the level country 
about Buffalo it is rarely seen. 
Anax junius Drury. Common everywhere through June and 
July. I once watched one of these insects pursuing gnats about a spruce 
tree until it was so dark I could no longer discern him before the fading 
light in the western sky. 
Macromia illinoiensis Walsh. Taken by Mr. Philip Fischer on 
Grand Island. In July, 1895, I saw an example of this species resting 
on a store window in the heart of the city. 
Epicordulia princeps. Common about Black Rock Harbor 
through June and July. 
Tetragoneuria cynosura Say. June. With the next. 
Tetragoneuriasemiaquea Burm. Very abundant at Black Rock 
Harbor during June, 1895. Early in the month they were mostly soft
