A HISTORY OF SUFFOLK 



descriptions of new species. His A. barbatui I took at Bentley in May 1902 ; A. arcuatus, Kief., I 

 found in the same locality in July 1904, and A. imterhis, Kief., in Assington Thicks in May 1899. 

 Chitty's A. Kiejfferi was floating on a horse-trough in Ipswich in May 1895. A. Gaullei, Kief., 

 occurs on flowers in the Bramford marshes and on fumatory at Tattingstone in July ; while 

 A. Morleyi, Chitty, affected the flowers of meadow-sweet at Foxhall in August 1902. I have also 

 taken A. vicinus. Kief., by the Aide at Farnham and A. fusiformis. Kief., in a swamp at Reydon. 



Of the very rare Pedinomma rufescens, Westw., I captured the second or third British example 

 in a chalk pit in Barking on 6 October 1898 ; Mr. Marshall, to whom I gave it, first discovered 

 the S, also an apterous insect, in 1901. The second of Curtis's records refers to He lor us anomalipeSy 

 Panz., which he says the Rev. William Kirby had observed in Suffolk," where, indeed, it is fairly 

 common everywhere, though especially so at Aldeburgh and Sibton Abbey. Among the Belytinae 

 we have fifteen ill-defined species : an undescribed Acropmia occurred to me at Blakenham in May 

 1897 ; and in the genus Belyta, B.validicornis, Thorns., was taken at the same time and subsequently 

 at Brockdish (Norf.). B. depressa and B. abrupta, Thoms., have been found respectively at the Kessing- 

 land clifis in July and Stanstead Wood in the middle of June. The fourth and fifth species were taken 

 flying in the Bentley Woods 27 May 1900 ; and B. dorsalls, Thoms., was once swept in Dodnash 

 Woods in September. I have taken Pantociis brevis, Nees, in moss at Ipswich, and a species of the 

 same genus or Anectata in the Bentley Woods on 22 September 1899. A new species of Aclista 

 was also swept there on the same day, as well as A. brachyptera, Thoms., on 28 September 1895. 

 Single specimens of Ismarus favicornis, Thoms., at Southwold, Oxy/abis armata. Curt., at Bentley 

 Woods, and of a species of Xenotoma at Stanstead Wood in June, have also been noted. Turning now 

 to the Diapriinae, we find that Spilomicrus stlgmaticalis has been swept from herbage at Little Blaken- 

 ham ; S. nigripes, Thoms., is common at Tuddenham Fen, Ipswich, and Barnby Broad ; and that 

 S. integer has occurred at Wherstead on 27 October, 1903. Aneurrhynchus galeslfcrmh, Westw., 

 has been found in Bentley Woods, A. pentatomus, Thoms., at Stanstead Wood and Knight's Dales, 

 and A. nodicornis, Marsh., has also put in an appearance. Galesusfuscipennis, Curt., occurs at Bentley 

 and Belstead, and its variety was taken in the former woods on 1 1 July 1 902. Basa/ys antennata, 

 Nees, has once been taken at Foxhall in September ; and a new species of Paramesius beneath the 

 bark of a willow tree at Sproughton on 3 September 1897. The genus Loxotropa is represented hy 

 L. tritoma, Thoms., in Dodnash Woods ; L. tripartita, Marsh, (or dispar, Nees), on the banks of the 

 Orwell at Wherstead ; L. abrupta, Thoms., in a marshy wood at Bramford ; ^' and Galesus brevi- 

 cornis or ob/iguus, Thorns., at Bentley. The typical genus Diapria is represented by D. conica. 

 Fab., in the Bentley Woods, at Southwold and Claydon ; Mr. Chitty's first new species is not 

 Suffolcian, but the second was found in the centre of Framlingham ; D. verticillata, Latr., has 

 occurred at Claydon, and the third new species in the Bramford marshes ; £>. nigra, Nees, is 

 common at Easton Broad, Foxhall Decoy, and perhaps at Barren Heath, near Ipswich ; D. suspecta, 

 Nees, on brackish mud at Aldeburgh, at the roots of ragwort at Brandon, and of stonecrop at 

 Tuddenham. A fourth kind has appeared in flood refuse by the Gipping and on firs in the Bentley 

 Woods. Monelata petiolaris, Nees, has been found in damp moss in the same locality in the 

 autumn, together with the minute Leptacis scutellaris, Thoms., which sometimes lives in ants' nests. 

 Late in September 1905 my wife discovered on a white table-cloth, Alaptus minimus. Walk., one 

 of the most minute of our indigenous insects, measuring one-fiftieth of an inch in length. 



TENTHREDONIDEA 



The nomenclature of the sawflies is just now in a state or transition from that employed in 

 Cameron's British Phytophagous Hymenoptera to the more scientific system evolved by Pastor Konow, 

 as at present being set forth by the Rev. F. D. Morice in The Entomologists' Monthly Magaxine ; and 

 although Mr. Morice's nomenclature has not yet nearly fully appeared, and is still quite unfamiliar 

 to British students, it is thought advisable, in the following r&um6 of the Suffolk species, to adopt 

 for the most part the newer, more correct but less familiar names, which will shortly be the only 

 ones in genera! use. The sawflies of the county have been comparatively fijlly worked during the 

 past ten years, though never systematically, and new kinds are still constantly turning up as more 

 and more of the Broads, Breck, woods, and marsh-lands are explored entomologically. 



The curious little Xyela jullii occurs, though sparingly, on pine trees in Bentley Woods, where 

 Pamphilus sylvarum has once been taken and P. sylvaticus is of periodical appearance. The Cephina 

 are rather well represented by Janus cynosbati, which Mr. Chitty took at Brandon ; ^* Trachelus 

 tabidus from Boxford and Claydon ; Cephus pilosulus from Stanstead and Barton Mills ; C. pallidipes 

 from Moulton and Tuddenham ; and C. pygmaeus, which is only too common everywhere, and very
