ZOOLOGICAL NOTES 249 



Society " (vol. xvii. p. 42, footnote) I mentioned a number of 

 Hydrach7iidcB I had taken in the Forth Area. To these I would 

 now add the following, the first four of which have not, so far as I 

 know, been previously recorded from Scotland : — 



Eulais georgei, Soar. — On 13th May 1908 I captured a number 

 of immature examples of an Eulais in a pool on Gullane Links, 

 which Air. Soar considered were most likely nymphs of E. georgei. 

 An adult obtained in the same pool on 28th May of the present year 

 confirms his identification. 



Gnaphiscus setosus, Koenike. — A male and several females of this 

 species were taken at Crosswood Reservoir on the Pentlands, 31st 

 July 1908. I have to thank Mr. Soar for their determination. 



Uniojiicola (A fax) figiiralis (C. L. Koch). — On 2 8th August last 

 I got two males of this in a small loch on the Dunduff hills, near 

 Dunfermline. I mistook them for another species, U. c?'assipes 

 (Miill.), but Mr. Soar has pointed out to me the difference in the 

 number of acetabula. 



Arrhenurics cylindratus^ Piersig. — Regarding six Arrhe7iurus $ $ 

 from a pond at Drumshoreland, 13th June 1906, Mr. Halbert {in 

 lit.) says: "There is little doubt these are the females of this 

 species." 



A. inaadator (Miill). — A $ from Loch Ard, 14th July 1906, is 

 referred by Mr. Soar to this species. 



Hyd?'ypha7ites dispa?- (Schaub). — One from Loch Watson, near 

 Doune, 22nd April 1905. 



Fiona rufa (C. L. Koch). — Burntisland Reservoir, common, 

 14th August 1908, and Gosford Ponds, 28th July 1909. Loch near 

 Dunfermline, 28th August 1909. 



P. ciradaris (Piers.). — 5 5 Kidlaw Reservoir, Haddingtonshire, 

 31st July 1909. 



P. uncata (Koen.). — c^, Kidlaw Reservoir, 31st July 1909. 



I have now a list of sixty-two Hydrachnidb from this area. — 

 William Evans, Edinburgh. 



Arg'yroneta aquatiea, Latr., in Perthshire. — Several examples 

 of this interesting spider were captured on Saturday, 4th September, 

 while netting a weedy pool on Methven Moss. The species does 

 not seem to have been observed in Perthshire before. — Alex. M. 

 Rodger, Museum, Perth. 



Two New British Diptera. — It is with pleasure that I record 

 the following additions to the list of British Diptera, both due to 

 the energy and enthusiasm of my friend, the Rev. James Waterston. 

 In July last he brought to me for identification a series of specimens 

 belonging to the genus Spilogaster which he could not satisfactorily 

 refer to any species in Meade's "Descriptive List." With the aid 

 of Stein's 'xA.nalytische Uebersicht,' published in the " Entomologische
