DiPTERA. — Mr. Chris. A. Cheetham writes : — The general opinion 

 seemed to be that diptera were far too numerous, one species. Hydro iaea 

 irritans Fin., came in clouds about our heads, but if this had been cleared 

 away surprisingly few would have been seen. By vigorous use of the 

 sweep-net a good number were collected, and on working over these a 

 fair list of additions to the County list is available (these are indicated 

 by an asterisk). Seeing how scanty records are for this area, a full list 

 is given, as it will give some idea of the species available early in July 

 in a similar type of locality. Taking the most striking families first, 

 one brilliant Sargus (S. iridatus Scop.) was caught, of the Syrphids few 

 individuals were seen, the list being : — 



*Chilosia pulchripes Liv. (P.H.G. has previously verified this for me 

 from Ad el.) 

 Plaiychinis manicatus Mg., sciitatus Mg., albinianus F., scanibus Stacg., 



immayginatus Ztt., fulviventris Mcq., clypeatus Mg. 

 Pyrophaena granditarsa Forst. Liogaster metallina F. 



Syrphits venustiis Mg., grossulariae Mg., ribesii L., vitripennis Mg., 



balteatus Deg., cinctelliis Ztt. 

 Sphegina cluriipes Fin. Volucella pelluccns L. 



Eristalis intricarius L., pertinax Scop., horticola Deg. 

 H elophilus penditlits L. Xylota seguis L. 



On first arriving among the trees by the lake-side a number of 

 gnats were disturbed, a conspicuous species being the imago of the 

 Phantom larva, Corethra plmnicornis ¥., others being Cttlex pipiens L., 

 Chironomoiis pliimosus I>., and two other species which appear to belong 

 to C. brevilibialis Ztt., and Tanypits pmutipennis Mg., when tested by 

 Wingate's tables. 



Many additions to our list are among the daddy long legs, and here 

 I have to thank Mr. F. W. Edwards for assistance where his initials arc 

 appended :■ — • 



*l)icrauomyia mitis Mg. (F.\^'.E.) Ptyclioptcru nlhiiiuuia V. 



LiiiDiohia nubeculosa Mg., flying in threes or fours in llie mouths of large 

 rabbit Ijurrows.
