 (S. N. Rhoads, N. J. list) ; Jamesburg, N. J., IX; Lakehurst, N. J., 

 VIII, X. This is one of the latest of our dragonflies and is to be 

 found far into the fall. We have seen them in copulation on Staten 

 Island on November 8. They are much attracted to anything light 

 colored, like a newspaper lying on the ground, and several may often 

 be seen sunning themselves in such a situation. They will light on 

 your hat, if you keep quiet, and will show no inclination to fly away 

 provided you walk about quietly.
