of water flowed along the railroad track from several small springs. 
The bed of this small stream was composed of cinders and sand. The 
dragonfly alighted in the grass near this stream and placed her eggs 
in a small depression in the cinders. This depression contained not 
more than a tablespoonful of water. 
This species appears among the earliest dragonflies of the season in 
the South. It was found by the Senior author in early April at Rock 
Bluff on the Appalachicola River in West Florida. The place was near 
the Torreya Field Station of the University of Florida. Adults were 
resting on the trunks of the trees, or making short foraging sallies 
across the sunny openings between the trees, in a little nook at the 
mouth of a rill where it joins the great muddy river. A number of 
specimens were taken, but no egg laying was observed. Probably 
this species flies and forages a long time before the eggs are matured.
