 A HISTORY OF SUFFOLK Graphomyia maculata and Cyrtoneura stabulans are abundant ; C. pabulorum has been bred at Tostock from nests of Vespa vulgaris ; Luci/ia caesar and L. urica are common on flowers, and I once took a doubtful L. illuitris at Blakenham. The Anthomyidae are equally common ; of these we have the two usual Polietes, eighteen species of Hyetodesia, in addition to H. ohscurata taken at Exning in July ; Alloeostylus flaveola and A. simplex ; six species of Mydaea, twelve of Spilogaster, two of Limnophora, eleven of Hydrotaea, four of Hydrophoria, fourteen of Hylemyia, seven of Chortophila, twelve of Phorbia, and five of Pegomyia. Sphecolyma inanis has been bred by Tuck from nests of Vespa germanica ; Melanochila riparia occurs at Foxhall ; Ophyra leucostoma and Drymia hamata are occasionally met with ; Trichopticus semipellucidus, with T. cunctans, and all the British species of the genus Anthomyia are also recorded, the rare A. albicincta having been taken once at Tostock. Mycophaga fungorum has been found about Bury St. Edmunds and the rare Chirosia abbitarsis at Foxhall. We have recently added Lasiops Roederi, ctenoctena, and L. Meadii from Newmarket. Among the Homalomyinae we have fourteen species of the typical genus and five Azelia, three Lispe, two Caricea, two Coenosia, together with Piezura pardalina, Coelomyia mo/lissa, Hoplogaster mollicula, and Fucellia maritima. The marsh-loving Cordyluridae are represented by Cordylura pudica at Hen- stead, C. pubera at Brandon, C. ciliata at Beccles and Claydon, and the common C. umbrosa ; ParalUlomma albipes at Foxhall and Bentley Woods, Cnemopogon apicalis at Barton Mills, Amaurosoma tibiella at Oulton Broad, Norellia spinimana, N. liturata, and A'^. spiniger, Trichopalpus fraternus, and Spathiophora hydromyzina ; eight species of Scatophaga, Ceratinostoma ostiorum on the banks of the Orwell and the Gipping, and Coniosternum obscurum at Harleston. Helomyza rufa and H. ustulata, Btepharoptera ruficauda, and B. serrata are common ; H. Zetterstedtii, montana, and H. pallida occur about Newmarket, and I took Allophyla atricornis at Brandon in 1903 ; Heteromyza atricomis and Tephrochlamys rufiventris are frequent, T. flavipes is found in the Bentley Woods, arid T. palkscens was taken in Ipswich in 1896. Trigonometopus frontatus is our only representative of the Heteroneuridae ; it occurs in some numbers on dead rushes at Foxhall in March, and doubtless hibernates among them. The Sciomyzidae in so well-watered a county as Suffolk are abundant ; Mr. Tuck has taken Actora aestuum at Aldeburgh in September, and both Dryomyza analis and D. flaveola are everywhere common ; of Sciomyza we have noted nine species, including S. Schoenherri near Ipswich, S. simplex at Barton Mills, and S. albocostata at Foxhall ; and ten of Tetanocera, of which mention may be made of T. sylvatica at Barnby Broad, T. punctata commonly, and T. umbrarum in reed refuse at Oulton Broad, Limnia marginata at Barham and Ipswich, and L, obliterata at Tostock and Aldeburgh. Elgiva dorsalis and E. rufa are common ; I took E. lineata at Tuddenham in 1 906, and Tuck has found E. albiseta at Tostock in July. The carrot-fly Psila rosae is too common, I have taken P. fimetaria at Ipswich and Tuddenham, and both P. nigricornis and villosula are found at New- market. Chyliza atriseta occurs at Bramford, C. leptogaster in Tuddenham Fen, and in June 1902 Tuck took C. vittata, which was new to Britain, at Bungay ; Loxocera aristata and L. albiseta are generally distributed, and I once beat L. sylvatica in the Bentley Woods. Micropeza lateralis is rare upon dry heath grasses at Foxhall, M. corrigiolata common with Calobata ephippium ; C. petronella occurs commonly in Ipswich gardens, and Verrall took C. cibaria at Fritton in 188 1. Of the Ortalidae, the only British specimen of Tanypeza longimana was captured at Tostock by Tuck in July 1899 ; '' Dorycera graminum is not rare, nor also probably is Piilonota centralis. Pteropaectria frondescentiae is frequent on rushes, and P. afflicta and P. nigrina have been met with here ; Ceroxys pictus is abundant in the coast salt marshes and C. crassipennis in all the broads and fens. Platystoma seminationis is often a pest in June, with Rivellia syngenesiae ; Seoptera vibrans is local at Theberton, Southwold, Monk Soham, and Tuddenham Fen ; Ulidia erythropthalma is not uncommon, but Chrysomyxa demandata is rare. Comparatively little attention has been paid to the pretty little Trypetidae, and we can only instance the celery-fly, Acidia heraclei and A. Ifchnidis, Gonyglossum Wiedemanni at Blakenham and Newmarket, Spilographa Zoe at Tuddenham on birch, Trypeta jaceae at Yoxford ; T. onotrophes and T. florescentiae are common, T. cornuta has occurred at Ipswich, T. tussilaginis at Oulton Broad, and T. serratula at Farnham. Urophora solstitialis and U. stylata, with Sphenella marginata, are frequent ; Ensina sonchi has been taken at Southwold, Urellia stellata at Foxhall, and six species of Tephritis comprise our list — T. plantaginis abundant about Southwold, T. formosa at Bentley and Tostock, and the widely-distributed T. bardanae. Of the Lonchaeidae, L. vaginalis is abundant, L. chorea found near Needham, L. tarsata bred by me from a Tortrix pupa at Foxhall ; and I also took upon thistles in the Bentley Woods, 1895, what Dr. Meade called L, fumosa, Egger. Palloptera ustulata, P. umbellatarum, and P. arcuata are common, but I have only found P. saltuum at Southwold, and Taxoneura muliebris has been taken at Bramford, &c. Peplomyza Wiedemanni occurs at Barton Mills, Sapromyza marginalis, fasciata, inusta, decempunctatOy biumhrata, rorida, praeusta, and plumicornis are all recorded from the county, with S. lupulina fron: Wherstead, " Cf.
