8. precor. 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. Ihave met with 
the species also on the banks of the Thames, but always within the range 
of the tide.]
