small dark yellow lateral basal spots. 
“This large robust species is mainly an inhabitant of lakes rather 
than ponds or streams.—Males were flying here and there over the 
water, pursuing a rather irregular course, now following the shore line, 
now wandering out over the water in a manner suggestive of Epicor- 
dulia or Tetragoneuria. They were not observed to hover over one spot 
on the usual manner of Cordulines. Several times males were seen to 
attempt to capture the females during flight. One or two of these 
attempts resulted in copulation, the pair immediately flying off into 
the trees. A pair in copula was also taken on July 24 in the pine barrens 
a mile or so from any of the lakes.”” Walk. (’25, p. 189).

Walk. ’25 says: 
.... They are usually found flying back and forth in small, sheltered, shady 
opening in woods or along their partly shaded borders. Their flight is generally 
about shoulder high on an average and I have never seen them flying at a height 
beyond reach of an ordinary net.

They are characteristic dragonflies of small clear streams, with a gentle cur- 
rent, and do not occur where pond conditions, indicated by the presence of water 
lilies, Myriophyllum or cat-tails obtain. They seldom occur where the stream 
flows through dense shade nor are they often seen in open bogs, but are most at
