June, 1897.] 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. 



Qomphus spicatus Selys. Taken in a tamarack swamp at Clarence 

 in July, and rarely about Black Rock Harbor, in June. 



Qomphus f raternus 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. 



Episeschna 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 Dniry. 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. 



Tetragoneuria semiaquea Bunn. Very abundant at Black Rock 

 Harbor during June, 1895. Early in the month they were mostly soft
