EUMERUS STRIGATUS AND OTHER DIPTERA 23 



Other diptera tal^en in the Forth area are as follows : 



Sciara rufiventris, Mcq. One, Kirknewton, Midlothian, 8th 

 August 1904; 9, Luffness Links, East Lothian, 26th July 1913 

 (identification confirmed by Mr F. W. Edwards). S. carbonaria, 

 Mg. Two, Morningside, Edinburgh, Sept. and Oct. 1907; one, 

 Gifford, June igi6. 



Mycetophila signata, Mg. $ and $ , Tyninghame, East Lothian, 

 October 1910. M. li/nata, Mg. S, Balerno, Midlothian, April 

 1906. M. rt/fescefis, Ztt. $, in Stereum hirsutum on dead beech, 

 Aberdour, Fife, February 191 5; and one, Morningside, January 

 191 7. (All determined by Mr Grimshaw.) 



Macrocera anguiata, Mg. One, Loch Ard, S.W. Perth, July 

 1906 (determined by Mr Grimshaw). 



Bibio kpidus, Lw. As I have already mentioned in this 

 magazine (191 2, p. 279), the crop of a partridge shot near Denny, 

 StirHngshire, on 15th Oct. 19 12, was filled with this dipteron. It 

 has since been met with on Benarty Hill, Fifeshire. B. lepidus was 

 mentioned as a Scottish species by Dr Buchanan White in Scot. 

 Nat, 1873, p. 23. 



Simuliitm. My Forth specimens of this genus were submitted to 

 Mr Edwards in October 1915 and referred by him to the following 

 species, viz. : ,5. or7iatunu Mg., Mortonhall (May 1895), Comiston, 

 Arniston, Balerno, and other places in Midlothian; Pressmennan, 

 East Lothian (July 191 1); Blair Adam, Kinross-shire (May 1905). 

 S. reptans, L., Saltoun, East Lothian (Sept. 1903). S. latipes, Mg., 

 Comiston, Midlothian (Sept. 1896 and Oct. 19 10). S. eqiiinutn, L. 

 (Edw.), banks of the Tyne at East Linton, East Lothian (April 

 1 913). The record of the last mentioned species has already 

 appeared in the E^it. Mo. Mag. for December 19 15, p. 331. 



Chironomus rufipes, L. $ , Tynefield, near Dunbar, August 

 1894. 



CajHptodadius, sp./^ On ist July 1916 a troop of very small black 

 chironomids were observed flying over a rock pool, well out towards 

 low-water mark, on the Haddingtonshire coast, east of Port Seton. 

 They skimmed so close to the surface of the water that it was 

 impossible to capture them without sweeping water also into the 

 net, to the detriment, of course, of the specimens. The pool was 

 doubtless their breeding-place. The few I secured were all males. 



1 C. thalassophilus^ Goetghebuer, an addition to the British list (determined 

 27th January 1920 by Mr Edward?:, ^ho tells me he took the species on the coast 

 of Arran last May).
