 distinct.] 



8. prcecox. Meig. IV, 64, 8. 



[I find this species on the sea-coast so early as March : on fine days 

 about Midsummer a little before high-tide they may be seen in swarms 

 resting lightly on the surface of the waves, and carried on by their advance : 

 numbers of them will be found paired in this situation. I have met with 

 the species also on the banks of the Thames, but always within the range 

 of the tide.]
