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 ^Eschna as I could see with my glass, but none flew 
low enough to permit of capture.

pupas, and all that were seen closely were males. 
Tramea Carolina Linne. May, June, July, August, September 
^ J 11 Y I ^ 94 > a male Tramea carolma 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 amono- 
the disturbers was a Libellula basalis. After a time the male Tramea 
left his mate and she was quickly seized by the aforesaid Libellula 
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.
