 A HISTORY OF SUFFOLK in Newmarket. Cordyla flavicepi has been found at Tuddenham, both C. crasslcernis and C. brevicomis at Newmarket, with Dynatosoma fusc'icorne, Mycetophila luctuosa is found with M. obscura at Tud- denham, M. punctata, cingulum, and /ineo/a are common in the Bentley Woods ; M. bimaculata in Ipswich ; unipunctata has been found at Tuddenham, M. dimidiata, xanthopyga and spectahilh at Newmarket. Rhymosia trunctaia has occurred in Mr. Verrall's study, and Exechia interruptOy E.spinigera, E. fungorum, and E. tenuicornis in his garden ; £. /(7/fra/« is not uncommonly beaten from yew trees in Bentley Woods in February. Mycothera dimidiata, Brachycampta alternans, B. bico/or^ B. griselcoUis, and B. serena are all found at Newmarket, the last also at Exning ; Docosia sciarina has been noted at Coddenham and D. valida is often abundant at Bentley Woods on oak-trunks in May. Phronia Girschneri is recorded from Newmarket, Collin has taken Sceptort'ia nigra at Tudden- ham in September, and I have presented Zygomyia pictipennis, from the Bentley Woods in February on fir trees, to the British Museum, as it was previously doubtfully British. Z. notata, Z. vara^ Z. valida and Acnemia nitidicollis occur at Newmarket. I have taken Sciophila marginata in the Bentley Woods and at Blakenham ; and hear from Mr. Collin that S. occultans, S. incisurata, and S. fimbriata all occur at Tuddenham, with S. tumida at Newmarket. Glaphyroptera fasciipennit affects flowers at Bramford and Foxhall ; and both G. winthemii and G. fasciola are found at New- market, together with Lasiosoma hirtum and L. luteum. The genus Platyura is represented by P. marginata at Ipswich, P. atrata at Bildeston, P. cincta and P. nana at Newmarket, and tiie P. intincta of Shiner at Henstead. I have caught Ceroplates tipuloides in Staverton Thicks ; and Mycetobia pallidipes on exuding sap at Brandon. Macrocera fasciata, lutea, centralis, stigma, phaleratOy pusilla, and crassicornis all occur in Newmarket, with Bolitophila fusca, and at Tuddenham, B. cinerea. Mr. Tuck confirmed Ditomyia fasciata as British by the capture of a specimen at Tostock.* The typical genus of the Bibionidae is well represented, but of the others we only have Anarete candidata, Scatpse clavipes, albitarsis, recurva, and S. brevicornis at Newmarket, S. notata at Coddenham, S. halterata abundantly at Foxhall, and S. flavicoUis, which I once found ovipositing in a fungus in Tattingstone Park ; both Dilophus albipennis and D. fehrilis are plentiful. Among the fifteen species of Bibio in the British list only B. ferruginatus, venosus, and lacteipennis yet remain to be found here. Simulium ornatum has occurred to me at Foxhall, 6'. reptans and S. (?)argyreata are abundant in the Breck district, and Verrall has found S. nanum at Tuddenham. The extensive families Chironomidae and Psychodidae are represented for the most part by specimens from New- market — understood hereinafter — and elsewhere in Mr. Verrall's collection, where I have seen Chironomus dorsalis, tentans, chloris, and albimanus. I have found C. plumosus at Oulton Broad and Ipswich, C. riparius at Wherstead and Whitton, C. rufipes at Claydon, and C dispar in my study in Ipswich in 1895. Verrall has Cricotopus molitator, bicinctus, and annulipes, Camptocladius aterrimuSy byssinus, and minimus ; Orthocladius variabilis and stercorius ; with Diamesa ohscurimanus. At Ipswich I have found Metriocnemus fuscipes at light, and Tanypus varius ; T. nebulosus turns up at Bramford in May, and T. choreus, carneus, melanops, and pygmaeus are in Verrall's collection. Ceratopogon myrmeco- philus is the proper name of the species recorded from Bentley Woods ; ' C. pulicaris is common in Suffolk, with C. y^wcro/M in marshy places; and Verrall has C.piceus,ciliatus,/rutetorum,variuSy pictipennis, and niger. Among the Psychodidae Verrall has recorded Pericoma nubila and P. fusca from Fritton ; P. ocellaris and P. auriculata are also in his collection. I have often swept the common Psychoda phalaenoides from reeds, and P. albipennis, P. sexpunctata, and P. humeralis occur at Newmarket, with Trichomyia urbica. Of the mosquitoes Anopheles bifurcatus occurs at Foxhall^ Mildenhall, and Wherstead ; the common A. macuUpennis at Newmarket, Southwold, Bury, Hales- worth, Wickham Market, Blakenham, Bawdsey, and Newbourn, Of the gnats Culex annulatuSy and pipiens are only too common ; but C. dorsalis, the Aldeburgh biting gnat, said to have been originally imported in ships from Norway, is decidedly local at that place and at Southwold ; * and C. bicolor is rarely attracted to sugar on trees in the Bentley Woods. Verrall adds Corethra fusca, and the Dixid Dixia nebulosa. Ptychoptera contaminata, alhimana, and scutellaris are all common near streams, and P. paludosa occurs at Exning in August. Among the Limnobidae I have seen Limnobia bifasciata abundantly on sugar in the Bentley Woods ; L. quadrinotata, nubeculosa, and analis about Ipswich ; L. nigropunctata abundantly in woods at Assington and Bentley, and L. favipes at Wher- stead. Verrall has L. tripunctata, Dicranomyia sericata, and Rhipidia maculata from Newmarket,, with D. modesta from Mildenhall, D. didyma and D. dumetorum from Barton Mills ; D. lutea often dances in crowds in Ipswich and Southwold, D. chorea occurs in Ipswich houses, and I once found D. morio in a sand-pit. Both Empeda nubila and Goniomyia tenella, with Acyphona maculata, arc found in Newmarket, and Chilotricha imhuta at Exning. Molophilus appendiculatus, bifilatus, and obscurus have been found by Verrall, and M. propinquus occurs at Mildenhall in September. I have taken Rhypholopus lineatus on willows in Bentley Woods, and Curtis tells us he once took R. nodulosus 136
