86 THE ENTOMOLOGIST. 



and again in the middle of April at Beutle3\ In a peculiarly 

 marshy wood near the Suffolk coast at Blythburgh a great variety 

 of Mycetophilidae were found on birch bushes September 14th, 

 1912; and among them a couple of M. guttata, Dz., which was 

 on a Southwold window on September 10th, 1919 ; M. dimidiata 

 appears on the Monks Sobam windows about May 22nd, and at 

 Setley in the New Forest was another species on July 12th, 

 1909. 



Close to the sea at Southwold a fair number of Trichonta 

 suhmaculata, Staeg., were on the panes of a beach-sbelter at 

 6.15 p.m. on September 19th, 1913 ; and I took one that Mr. 

 Edwards considers a new species at Monks Sobam on August 18th, 

 1917, now in the British Museum. Rhymosi'i. fasciata is among 

 the most abundant kinds on the windows here from the end 

 of October to that of November (I have just taken it sitting 

 quiescently on an outhouse wall, November 24th, 1919) ; but 

 R. domestica has only occurred to me in a peculiarly sylvan spot 

 on Crow Wood Hill near Nottingham on August 9th, 1914. 

 Exechia /estiva, Winn., and E. cruciciera, Lun., also appear on 

 these windows in the late autumn ; both E. trivittata, Staeg., and 

 E.fungoriim occurred in the above damp wood at Blythburgh ; 

 E. parva, Lun., I beat from birch bushes on September 9th, 1915, 

 in Tuddenham Fen ; and somewhat doubtful E. guitiventris were 

 captured at Cromer in Norfolk during August, 1903, and at 

 Washbrook on March 27th, 1897. Allodia lagens, Wied., was 

 swept at Westleton on September 19th, 1912. Two rather 

 doubtful A. caudata, Winn., were in a beach-shelter at Southwold 

 on 25th of the following September ; the pretty little A. amoena, 

 Winn., beaten from Pinus sylvestris at Potters Bridge there five 

 days earlier ; and another species occurs on Monks Soham 

 windows during mid-May. 



The species of Mycothera and Brachycampta have hitherto 

 eluded me, though Verrall found several in this county. Docosia 

 valida, on the contrary, is abundant, quietly sitting on the trunks 

 of large oak trees in Bentley Woods early in May, and also on 

 those of Palmer's Heath at Brandon late in the month. D. 

 sciarina was swept from Mercurialis perennis on May 4th, 1901, 

 at Coddenham. My only D. (Megophthabnidia) crassicornis was 

 sucking the stylopods of Angelica sylvestris on September 1st, 

 1903, at Harkstead, near King Harold Godwinesson's hunting 

 estate. Zygomyia valida is abundant on Monks Soham windows 

 from August to November, and I took it at Cromer in Norfolk in 

 1903 during the former month ; Z. notata also was at the windows 

 here on August 2l8t, 1919. The handsome orange Glaphyroptera, 

 now called Leiomyia, species are always abundant on Heracleum 

 sphondylium flowers in the summer. G. fasciipennis thus occurred 

 at Peterborough in Northants on June 14th, 1908, at Foxhall on 

 September 10th, 1903, on thistle flowers in the Orford salt-
