218 PBor. p. E. UHLEB ON THE [Mar. 6, 



Beaulieu, Grand Etang, and on the Mount Gay estate. It was 

 found in the j'oung stages on the Grand Etang, March 2, along 

 the margin of running water, and in August it was found fully 

 developed on the surface of stagnant ponds and on a sluggish stream 

 near the sea. In the eastern United States along the seaboard its 

 habits are essentially the same as in Grenada. Near Baltimore it 

 lives on the ponds and around the overflowed freshwater marshes 

 among the cat-tails and rushes, where it creeps stealthily about in 

 search of small insects which fall into the water.
