the rank herbage that grows along their margins. As 

 these two conditions do not usually obtain in connection 

 with the same stream, this is perhaps one reason why 

 the two species are seldom found together.* Like its 

 congener it is fond of running water, and does not fre- 

 quent stagnant ponds. The flight of the two insects is 

 similar also, being weak, and seldom sustained for many 

 yards. These Dragonflies rest with wings closed over 

 their backs amongst the low herbage near the banks of 

 the stream the\- haunt. 



Migration. 



Though no migration of this species seems to have 

 been recorded, it often wanders some distance from 

 its haunts, and when so wandering its flight is by 

 no means weak.
