THE BRITISH NATURALIST. [August, 1894. 



On Aquatic Diptera. — Mr. Swainson in his article on " Some 

 Curious Aquatic Larvae," mentions that Mr. Ridley found Thalasso- 

 myia Frauenfeldi in a cave, in the Isle of Wight, in 1884. If Mr - 

 Sw ainson would only read the Entomologists' Monthly Magazine , vol. xx. 

 p. 214, he will find that I took both sexes of it on Nov. 4th, 1868, in 

 a cave, under the cliff at Freshwater, Isle of Wight. Probably my 

 account of it led Mr. Ridley to find it there. In the same article I re- 

 marked another species of the same family, Clunio mavitimus, Hal., as 

 skimming over pools of water left by the receding tide, at Hastings. I 

 again met with T. Frauenfeldi in the Isle of Man, sitting on rocks, in 

 October, 1891. This may be of interest, as Mr. Swainson found his 

 Campontia there. Probably both Thalassomyia and Clunio are pretty 

 generally distributed round our coast, and only want looking for. 

 There are at least two others of the same family which occur on sea- 

 weeds. There are papers by Mr. Haliday on marine insects, in the 

 Natural History Review, and he also gives a list in it of British Diptera, 

 the earlier stages of which are more or less perfectly known. There 

 are so many books on Natural History at the present time that people 

 may well be forgiven for overlooking the proceedings of the predecessors, H
