COLLECTING FUNGUS-GNATS. 87 



marshes on July 7th, 1919, and on (iKerophyllum si/lvestre at 

 Claydon on June 16th, 1903; and a species, probably G. cylin- 

 drica, Winn., abounded at Staverton Thicks a few miles away 

 during the preceding August ; (}. sahfasciatas, the very distinct 

 G. wintliemi and a fifth species, frequent the windows at Monks 

 Soham during June, August and September. 



Anadinia nemoraUs I have only beaten from mountain-ash in 

 Bentley Woods on May 29tb, 1902, and swept at Market Kazen 

 in Lincolnshire on 11th of that month in 1912. Boletina hasalis 

 was also swept at Bentley on May 13th, 1900 ; and on June 17th, 

 1907, I was so fortunate as to take B. dispecta, Dz., on bracken 

 in the New Forest, Wilverley Inclosure, which specimen alone 

 represents the species in the British Museum. The large and 

 handsome Leptomorphus Walkert is surely rare, for it has occurred 

 to me only on July 22nd, 1904, at Cutler's Wood in Freston. 

 Lasiosonia hirtum occurs on the windows here in July and August, 

 as well as in May ; Sciophila (Mijcomyia) j/?a;v/rnrfto appears there 

 in June, and in the Bentley Woods from April 11th to May 20th 

 sometimes on fir branches. S. fasciata was on " The Elms " 

 windows at Ryde in the Isle of Wight on March 16th, 1898 ; >S'. 

 incisiiyata in the above Blythburgh Wood ; M. luconim in 

 Staverton Thicks on September 7th, 1916 ; and other species 

 occur on these windows in August and early October. 



The Ceroplatinffi are doubtless the most abundant group as 

 regards specimens; and Asindalum rost ratu m, Ztt., a.hoi\nds on 

 tables of SpJiondylium in my orchard here throughout July, 

 frequently in cop. or hovering in little clouds close to the flowers. 

 The large black A. nigrum, Latr.,was long mistaken for P/af ?/«?•« 

 atrata by Dr. Meade ; and Piffard thought it P. inticta of Schiner ; 

 I met with a good many examples on July 12th, 1900, onlv, on 

 both Angelica and Heracleum flowers in marshes at Henstead 

 and Kessingland. Of the genus Plattjura, the large i^. margimita 

 was found at Setley and Burley in the New Forest on Erica 

 tetralix during June and July, as well as on reeds by the Orwell 

 at Ipswich on June 1st, 1897. P. atrata was sitting on the road 

 at Bildeston on July 30th, 1898, but P. semirufa is not rare in 

 August and September on umbelliferous flowers at Lyndhurst 

 and Matley in New Forest, at Crow Wood Hill near Notts., at 

 Chippenham Fen in Cambs., and in Suffolk at Easton Broad, 

 Monks Soham, Tuddenham Fen, Staverton and South Cove. P. 

 fiava occurred at Grovely Wood near Salisbury on June 27th, 

 1911, with a doubtful specimen beaten from oak at Staverton on 

 June 14th, 1904; P. fasciata was found at Crouch Hill near 

 London on June 11th, 1907, and on August 15th, 1913, I took 

 one flying in a garden hut at Monks Soham, exactly like Cidex 

 pipiens. P. nemoralis is common on windows here from the end 

 of May to July 23rd ; also I have found it among ])lantains in 

 the lawns and at Tannington sitting on the sawn end of timber.
