Sept. 1898.] Davis: Dragonflies of Staten Island. 197 



these dragon flies was seen to crawl down a stick lying in the water 

 until it was entirely below the surface of the pool, as recorded in Ento- 

 mologica Americana, Vol. I, p. 18. 



/Eschna constricta Say. June, September, October. On 

 August 26, 1894, about six P. M., several hundred dragon flies were 

 seen flying westward over Slosson's Lane, West New Brighton. They 

 were a species of Alschna as I could see with my glass, but none flew 

 low enough to permit of capture.

 July 30, 1887, at New Brighton. On July 31, 1887, there were 

 many specimens near the reservoir of the Crystal Water Company at 

 Four Corners, nearly all of them keeping over a field of oats. They 

 were quite difficult to capture, except those newly emerged from the 

 pupa?, and all that were seen closely were males. 



Tramea Carolina Limit. May, June, July, August, September 

 On July 15, 1894, a male Tramea Carolina was flying over one of 

 the Four Corners iron mine ponds. Soon a female came and com- 

 menced dipping her abdomen into the water. In a moment she was 

 seized by the male and they flew away. In a half hour they were back 

 and went flying about together, the male now and then suddenly letting 

 go his hold and with equal rapidity catching the female again by the 

 neck. Other male dragonflies flew after them and when the female 

 stopped to lay eggs, they annoyed her considerably. The chief among 

 the disturbers was a Libeliula basalis. After a time the male Tramea 

 left his mate and she was quickly seized by the aforesaid Libeliula 

 basalis, after which they flew about together for a considerable time. 

 After letting go his hold once and flying down the pond, the L. basalis 

 returned and seized the Tramea a second time.

 Often quite abundant on the salt meadows. 



Libeliula basalis Say. June, July.
