description, it is the same fly I have frequently seen on the pier end at 

 St. Anne's-on-the-Sea, where the females were probably waiting for the 

 receding tide to give them an opportunity of laying their eggs on the 

 Obei ia Zoophytes when once more uncovered, and where I have 

 more than once found the larvae, for says Schiner, " Herr Von 

 Frauenfeld caught the specimen near Trieste, close to the sea 

 shore, where it sat on rocks within the reach of the dashing breakers ; " 

 and Mr. H. M. Ridley, who found the species in a cave in the Isle of 

 Wight in 1884, says, " they were sitting on the rock seeming to enjoy 

 the dashing spray of the rising tide." We must now refer our readers 

 to Mr. F. V. Theobald's excellent account of British Flies, Vol. I., for 

 some interesting notes on Parthenogenesis in Chivonomus, which I sent 

 him. The following are some new and unnamed species of larvae 

 of Chironomus, which have been recently discovered and mounted.'"

As some encouragement to young naturalists who wish to make a 

 name for themselves, we may say that the above represent new and 

 undescribed species, which we met with in 1892, on watercress, &c. 

 How open the field is to others may be judged from the fact that Mr. 

 Verrall enumerates as many as 268 distinct species of midges (Chivono- 

 midcE) indigenous to England, of which the larvae of only a dozen are 

 known. 



The larva, Fig. 3. i., was very active in his movements, and his 

 antennae were so long that I thought at first I had one of the Tanypus
