 INSECTS Bungay. Syrlta pipitns is abundant ; Eumerus sahulonum was captured by PifFard near Landguard Fort andi'. strigatus is not very uncommon. Chrysotoxum sylvarum, C. bicinctum, and C.festivum are common ; I have found C. elegans at Southwold, and Tuck has bred C. octomaculatum at Tostock in 1896 and 1897. Paget records Sericomyia horealis as occasionally common at Lound Heath, though not now met with for many years, and I took the fine Criorrhina asi/ica in Bentley Woods in 1904. The interesting family Conopidae is well represented in Suffolk. Of the typical genus Conops, C. flavipei, (luadrifasciatOy and ceriiformis are not uncommon, and Tuck has bred the variety vitellinus at Tostock. Physocephala rufipes and Oncomyia atra are also ubiquitous, but 0. pusilla and Zodion cinereum are very rarely met with, the former at Dodnash Woods and about Bury, the latter once only at Foxhall in August, and once at Brandon in June. Sicus ferruginem is often seen on ragwort flowers in the autumn ; Myopa buccata is recorded hence by Curtis, and more recently from the Bury district, &c. ; M. testacea was bred at Tostock by Tuck in May 1898, and M. fasciata, which I have captured at Foxhall, was found at Ipswich by Freeman about 1887. Among the bot-flies, the Oestridae, we can only positively claim two species, though Hypodermae are sure to occur ; these are Gastrop^i/us equ't, of which Mr. Tuck took several specimens at Tostock in August 1898, and others at Bungay in July; and Oestrus ovis, the sheep-fly, which he also found in the former village in July. Many of our parasitic flies of the family Tachinidae have not yet been determined, but we may mention Meigenia egens from flowers near Ipswich, Ceromasia machairopsis about Ipswich, C. sordidisquama and C. juvenilis common in Bentley Woods in May, C. senilis from Felixstowe, by PifFard (in the British Museum), and Dodnash Woods, C. stabulans about Ipswich and Lowestoft, and C. spectabilis on birch in Assington Thicks in June. Exorista vetula is found at Assington and Bentley, E. fimbriata and E. apicalrigria occur here (the latter being in the British Museum), E. perturbans is common on oak-trunks ; Mr. Ransom has bred E. jucunda at Sudbury from Liparis salicis, and Tuck found E. notabilis at Aldeburgh. Epicampocera succincta is common at Little Blakenham ; I have Blepharidea vulgaris bred from Pieris rapae and Abraxas grossulariata ; Myxexorista fauna has been captured in the Bentley Woods, where Bothria caesifrons and Phorocera serriventris are not rare; Blepharipoda atropivora has been noticed at Bramford, and Sisyropa hortulana in Bentley Woods ; 5. lucorum I have bred from lepidopterous pupae at Ipswich in July. Chaetolyga amoena occurs about Bury St. Edmunds, Tachina grandis in the Bentley Woods, T. erucarum at Felixstowe, and T. rustica with T. agilis about Ipswich ; Gonia divisa was captured in 1894, and at Foxhall in May I have taken G. ornata with G. lateralis. Monochaeta leucophaea and Thelymorpha vertigosa are rare about Ipswich ; Aporomyta dubia is abundant in the Bentley Woods ; Somohia rebaptizata widely distributed, and Pelatachina tibialis once occurred to me at Mildenhall in June. In the Bentley Woods Maccjuartia grisea, Degeeria medorina, Demoticus Plebejus and D. frontatus, Myiobia pacifica, Micropalpus pudicus (with the type of Meade's Nemoraea quadraticornis), all occur with more or less frequency. Ptilops chalybeata has turned up at Bramford, Anthracomyia nana at Hens- stead and Tostock, Micropalpus pictus at Claydon Bridge, M. vulpinus is certainly uncommon at Felixstowe and Tostock, but Thelaira leucozona and Erigone radicum are common enough. Tuck has taken E. rudis about Bury, and I have found E. vivida near Ipswich ; Echinomyia grossa has occurred to me at Barton Mills, and E. fera to Hocking at Copdock ; Plagia ruralis occurs in the Bentley Woods and P. trepida at Assington. PifFard says Phorichaeta carbonarius was abundant at Felixstowe in 1896, and presented it to the British Museum ; Discochaeta muscaria is rare at Assing- ton, but Roeselia antiqua is generally distributed, as also are Digonochaeta spinipennis and D. setipennis, Thryptocera crassicornis and T. bicolor, with the two Siphonae, have been noted. Early in 1897 I took what Dr. Meade said was Exorista [Blepharomyia) ampUcornis on oak-trunks in the Bentley Woods, and with it occurred what he considered a new species and named Phorocera incerta, a co- type of which is in the British Museum ; ' these Verrall synonymizes. I was also so fortunate as to add Phasia Rothi {Xysta cand) to the British list,*" having found it in the vicinity of Ipswich, where Alophora pusilla is sparingly met with. Few of the remaining sections of the Tachinidae, the Trixinae, Sarcophaginae, and the Dexinae, require particular mention ; in the first we have twelve species, including Trixa oestroidea^^ Tryphaera umbrinervis, and Dialyta atriceps ; in the second fourteen species, several of the typical genus Sarcophaga and the fine northern fly Cynomyia mortuorum from Orford and Tuddenham, the bee-parasite called Miltogramma punctatum, Hereronychia chaetoneura, and the interesting little Sphixapata conica from Bramford and Felixstowe ; in the last only four species, of which Dexiosoma caninum is found sitting commonly on bracken with, rarely, Dexia rustica in the Bentley Woods, and D. vacua at Worlington, and Prosena sybarita on the Breck sands, taken by the Hon. N. C. Rothschild, in August. Of the ubiquitous Muscidae, we have found all the Stomoxys, Pollenia, Myiospila, Musca, Morellia, Mesembrina, Pyrellia excepting P. cyanicolor^ ProtocalUphora, Calliphora, and Euphora ; »Cf. Ent. Mo.
