A HISTORY OF SUFFOLK 



occurs commonly at Bentley, Stilpon lunata at Foxhall, with Tachypeza nubila at Oulton and New- 

 market ; Tachista connexa is abundant, as was once Chersodromia cursitans on Malva on the beach 

 at Slaughdon ; Tachydromia alhiseta, by Verrall, at Brandon, T. flavipei at Needham, T. maculipes at 

 Foxhall, and T. femoralis at Claydon Bridge, have also been observed. Several recent additions 

 include Oreogeton flav'tpei, Leptopeza Jlavipes, Hemerodromia unilineata, Ardoptera guttata, Thamnodromia 

 vocatoria, Drapetis assimilis, Tachista arrogans, znd Elaphropexa ephipptata. The beautiful Dolichopo- 

 didae have recently come in for a good deal of attention, and we can enumerate four species of 

 Piikpus, Neurigona quadrifasciata, Eutarsus, aulicus and Hygroceuleuthus diadema, the last from Moulton 

 in June. The typical genus Dolichopus is represented by sixteen species, of which many are only 

 recorded from the Broads of the north-east or Fens of the north-west. The handsome Poedlobothrus 

 nobilitatus often occurs on my house-windows at Monk Soham ; Argyrae with silver bodies flit about 

 streams ; Machaer'mm maritimae is common by the salt-water Orwell ; Sce/Ius notatus may be swept 

 from reeds in our salt marshes, and the curious little Medeterus are seen sitting abundantly on 

 tree-trunks, &c. I have recently added Dolichopus griseipennis, D. trivia/is and D. acuticornis from 

 Monk Soham, D. lepidus and D. planitarsis from Tuddenham Fen, D. clavipes from Southwold, D. 

 ungulatus from Barham, Reydon, and Easton Broad, Xiphandrium monotrichum from Southwold, and 

 Hermtomus nigripennis from Henstead. In all seventy-three species of this family have been noticed 

 in the county. Of the last family of the orthorrhaphous diptera, the Lonchopteridae, we have all 

 the British kinds but Lonchoptera punctum and L. fuscipennis ; they are common, often turning up 

 even during the winter months. 



The first three families of the cyclorrhaphous diptera, the Platypezidae, Pipunculidae, and the 

 Syrphidae, are now well known on account of Mr. Verrall's fine work, which treats of them, and in 

 which, too, many Suffolk records are enumerated. Calllmyia speciosa has occurred at Newmarket, 

 and C. amoena at Brandon ; Platypeza atra was once found by me in the Bentley Woods ; ' both 

 P. dorsalis and P. infumata can be mentioned, the former from Newmarket, and the latter taken by 

 Mr. Piffard at Felixstowe ; Chalarm spurius is recorded from Verrall's garden, and Verrallia aucta 

 from Suffolk. Thirteen species of the extensive and distinct genus Pipunculus have been noticed 

 here, but others are sure to turn up, of these the following seem worth recording : Pipunculus halte- 

 ratus at Tuddenham, which is the only British locality, P. varipes at Bentley Woods and Tudden- 

 ham, and P. pratorum in Newmarket. I have captured Paragus tibialis at Oulton Broad and Bramford, 

 and P. bicolor on the banks of the Gipping. Pipizella virens and Pipiza noctiluca are common, P. 

 luteitarsis and P. bimaculata are recorded from Newmarket, and I took a male of P. lugubris about 

 Ipswich, in 1894. Cnemodon vitripennis is recorded by Verrall, Orthoneura nobilis has occurred about 

 Ipswich, and we can include all the species of Liogaster and Chrysogaster except C. macquarti. Of 

 Chilosia we have seventeen species ; of the rarer kinds may be noticed C, longula from Barton Mills, 

 C. honesta at Ipswich in 1893, ^- g''0!"i which is widely distributed, C. albipilla singly at Bentley 

 and Raydon in March, C. impressa common at Barnby Broad, and C. Bergenstammi at Tuddenham. 

 And of Platychirus eight are recorded ; the best are P. scambus from Aldeburgh and Southwold, 

 P.fiilviventris from Brandon and Bramford, and P. angustatus from Aldeburgh and Bentley. Pyrophaena 

 granditarsa is not uncommon, and P. rosarum has also been met with ; oi Melanostoma we have not 

 yet noticed M. dubium, though the fine Xanthandrus comtus occurs at Copdock, Leucozona leucorum 

 usually a common species bred from nests of Bombus terrestris by Tuck at Tostock, and I once 

 captured Ischyrosyrphus laternarius at Bramford in August. Catabomba pryastri is common ; and 

 Gibbs took C. selenetica at Orford in 1903. Twenty-two species of Syrphus have been identified 

 from the county, of which may be mentioned S. tricinctus at Lackford and the Bentley Woods, 

 S. annulatusy S. iriangulifer, S. punctulatus from Newmarket, and S. labiatarum from Barton Mills 

 and Tostock ; as well as the three Sphaerophoria and both species of the handsome genus Xantho- 

 gramma, Baccha elongata is local, but Ascia podriagrica a.nd JJora lis occur freely; A. dispar is also said 

 to have been found here. The rare Brachypoda bicolor has twice been captured by me at so distant 

 localities as Belstead and Brandon ; Rhingia campestris, Volucella bombylans, and y. pellucens are com- 

 mon, and I once found V, inflata in the Bentley Woods. We have not found Eristalis cr\ptarum 

 nor rupium, but the other members of the genus are of frequent occurrence, E. aeneus being often 

 abundant on the coast. Myiatropa florea and Helophilus pendulus are a nuisance on flowers, though 

 H. trivittatus in various localities, H. hybridus at Cornard by Harwood, H. transfugus at Walbers- 

 wick, H. lineatus about Ipswich, and H.. vittatus (the Ruddii of Curtis) from Breydon marshes, 

 never seem to be met with in any numbers. Merodon equestris occurs at Bury, and I have found it 

 in an Ipswich house, and Tropidia scita is abundant in the fens and marshes. Criorrhina berberina is 

 noticed in Bentley Woods, C, oxyacanthae at the same locality and at Bungay,* C. floccosa is bred at 

 Tostock by Tuck, with the rare and handsome Pocota apiformis. I have captured Xylota nemorum at 

 Barham, X. segnis at Foxhall, X. lenta has been found at Copdock, and X. sylvarum at Tostock and
