62. Lepthemis vesiculosa.

This species was very abundant and very war\- at the lake 

 or pond where it was taken May 21. During the afternoon a 

 short but heavy rainstorm came up and the Lepthemis at once 

 took shelter in the alders, where they hung, often with the 

 water pouring in a miniature stream from the apex of the 

 abdomen. So drenched they were easily caught in the hand, 

 but with cessation of the rain and the immediate appearance of 

 the sun, they all took to the wing with unabated if not in- 

 creased vigor. 



Frequently they were observed feeding on a common fly, 

 which has kindly been identified for me by Professor Hine as 

 Anthrax fulvohirta. Lepthemis vesiculosa and Erythemis svm- 

 plicicollis are the most voracious feeders known to me among 

 the dragonflies. Both are grass green, both hunt in vegeta- 

 tion, especially simplicicoUis, and I have seen vesiculosa strike 

 like a falcon and kill dragonflies as large as itself.
