 Of water shells, Limnccu pcrarra was common in a water 

 trough, and at the lower end of Fewston Reservoir, where 

 also was found a broken shell of what is most likely /-. 

 atcricularia, a species which has before been found there. Only 

 one slug was seen, Agriolimax agrestis, and four species of 

 land shells, Vitrinii pelliici'da. Helix /lispida, Pattilu rottoidata^ 

 and Hyalinia alliaria, the last-named being additional to the 

 lists given in the circular. 



Mr. J. H. Ashworth kindly forwards the following list of 

 Diptera taken at Fewston, which it is as well to put on record, 

 as the changes in connection with the Waterworks and the 

 afforestation may affect the fauna to some extent. Most of the 

 specimens have been examined by Mr. Percy Grimshaw, of 

 Edinburgh.

For the Entomological Section Mr. A. Whitaker reports 

 that very little work was done. E. jitnira, C. pampliilus, and 

 L. icartis were abundant, and /'. aia/anhi was noted. Ova of 

 S popiili and D. viniila were obser\ ed on the small poplars by 

 the reservoir. 



A beetle was handed to Mr. Roebuck on the excursion, and 

 submitted to Mr. F. G. Hayfoid, who writes : — 



'This is a specimen of Aiirisironychit alniomimilis F., a very 

 interesting and uncommon species, for which we possess very 

 few recorded localities in Yorkshire. An incident of this kind 

 serves to emphasise the desirability of members assisting each
