Another species with an aquatic larva, but much commoner 

 than the last. It is recorded in Stephens' Illustrations by Mr. 

 Wailes from ''Meldon Park, Prestwick Carr, Marsden, &c.," 

 and by Mr. Hewitson from Newcastle (see Step. Illust., vol. iv., 

 p. 39). Mr. Hewitson's specimens were probably taken in 

 Jesmond Dene, where Mr. Henderson took it more recently. 

 Mr. Maling got this species on the boggy part of JSTewbiggin 

 Moor (see Trans , vol. v., p. 145). Mr. Finlay found it at a 

 lake to the west of IS'etherwitton, but does not mention Meldon 

 where Wailes took it so long before. Mr. Patterson got it at 

 Chopwell. It is recorded " among rushes in ponds near 

 Durham " in Ornsby's work. Mr. Gardner and I have taken it 

 about Greatham. I also took it at Throston Carrs before this 

 place was drained, and I have seen it sitting on palings close to 

 the town. More recently I have taken it in damp hollows at 

 Black Hall Rocks, not near any pond. Mr. Jeffrey found the 

 larva would spin up on Myosotis, and it has been shown they 

 would eat almost any water plant. I cannot but think they 

 will be found to live on plants growing in damp places as well 

 as on true water plants. The insect is common and widely 

 distributed, and is certain to occur all over both counties.
