INSECTS fifty British species only eighteen have been observed, amongst which L. notula occurs on reeds in Oulton Broad, L. lineola in Dodnash Woods, and on the banks of the Orwell, L. longipennh in tufts of Carex pankulata at Foxhall in the winter ; L. vitttpennis is abundant in Tuddenham Fen, where Elliott has taken L. fuscovittata in some numbers ; and L. punctulum with L. pelludda and L. scotti about Lowestoft, where it was found by Butler, as well as at Claydon Bridge and Foxhall. Mr. Edwards tells us' that L., or Chloriona, glaucescens, Fieb. — formerly thought to be C. unicolor, H. S. — has been found by him commonly on reeds in the coast marshes at Southwold in August. L. leptosoma and L. limbata are common, and L. eUgantula local at Foxhall, Kentford, and Tudden- ham ; but L. speciosa, which does not appear to have been taken in Britain for many years, has been but sparingly met with by Mr. Elliott and myself in marshes at Ipswich, Barton Mills, Brandon and Tuddenham Fen. The remaining species are Liburnia difficUis^ discolor, exigua, Fairmairei, and lineata, whose distribution is not yet fully known. Of the rest of the Delphacidae, I have seen Dicranotropus hamata from Foxhall to Tuddenham, and Stiroma pteridis common on bracken, P. albomarginata at Bentley and Tuddenham, P. affinh once swept at Freston in 1904. The extremely handsome Triecphora vulnerata is by no means uncommon upon young poplars and flying in the sunshine in the Bentley Woods, Assington Thicks, and Holbrook Park in June ; both species of Aphrophora live about Ipswich and Bury ; and all the British Philaeni, or ' Cuckoo-spits,' are common, though P. lineatus appears somewhat local, and several forms of P. spumarius have not been met with. Ledra aurita is uncommon on oaks in the Bentley Woods, at Tostock and Battisford ; Ulopa reticulata often swarms beneath heather ; and Megophthalmus scanicus is very common. Among the pretty family Bythoscopidae, we have a much better percentage of representatives. Afacropsis lanio is often beaten from oak trees ; Bythoscopus atni rarely met with on the banks of the Gipping and in Bentley Woods, where as elsewhere B. flavicollis abounds ; the rare B. rufusculus has occurred singly in Tuddenham Fen and the Bentley Woods in 1904. Pediopsis scutellatus, P. tibialis, P. impurus, and P. ulmi all occur with fair fre- quency, and last year I discovered P. cereus in Tuddenham Fen and P. fuscinervis at Foxhall, both in August ; C. virescens, too, has lately turned up at Tostock, Kentford, and Barham. Idiocerus adustus, I. populi and /. confusus are not infrequent upon poplars and willows ; an example from Farnham appears referable to I.fulgidus ; and I have also recently found here /. lituratus in Tud- denham Fen and /. distinguer.dus in Assington Thicks, which latter Mr. Tuck took at Aldeburgh ;* /. albicans is local at Freston, Tuddenham, and Brandon, and a single /. tremulae has occurred in Bentley Woods. Agallia puncticeps and A. venosa both occur, the latter being widely distributed at Claydon, Southwold, and Brandon. Evacanthus interruptus, upon ragwort, and E. acuminatus are both found in the Bramford chalk pits ; and Tettigonia viridis is often a pest in marshes throughout the county. We possess all the British Acoctphali, the only uncommon one being A. flavostriatus, which Butler has turned up in Fritton Decoy and I have seen at Kessingland. Eupelix cuspidata has only been noticed on the Breck sands and Foxhall Plateau ; but Doratura stylata and Paramesus nervosus, of the former of which I captured a specimen of the macropterous form at Ipswich in 1896, are common. I also beat a single Glyptocephalus proceps at Barren Heath near Ipswich in July 1904. The Jassidae leave much to be desired ; the only common Athysani being A. hrevipennis, communis, sordidus, obsoletus, and obscurellus ; Butler has found A. grisescens at Lowestoft. Twelve kinds of Deltocephalus are enumerated, of which five — D. pascuellus, coronifer, distinguendus, sabulicola, and punctum — were first taken by Butler about Lowestoft ; Edwards records D. Normani from Fritton, and I have seen D. argus in the Westleton lamb-pits and at Foxhall, where D. citrinellus, ocellaris, and striatus also occur. D. Flori and D. pulicaris appear to be rare at Freston.' Allygus mixtus, Limotettix antennata, and L. quadrinotata are common, as also probably is L. sulphurella, though I had not met with it till last August, when the rare L. aurantipes occurred to me at Foxhall and Bramford marshes. Of our six species of Thamnotettix, Tuck met with T. splendidula at Tostock in October 1899 ; and I beat a couple of T. Torneella from birch in the Bentley Woods in May and June 1902, from bushes through which I have beaten with no sign of this insect for ten consecutive years ; it is rare in Britain, but has a wide range from Rannoch to the New Forest. T. attenuata first turned up, and then commonly, at Foxhall late in September 1 904. Edwards has found the rare Cicadula jasciifrons at Southwold; and I have once or twice met with C. sep- temnotata, which is much rarer here than C. sexnotata ; Gnathodes punctatus is local at Bentley Woods and Foxhall. Alebra albostriella has been observed, and, in Tuddenham Fen, in June 1901, I took three examples of an allied insect, which was common there on birch, though apparently hitherto unrecognized in Britain. Dicraneura variata is abundant and D. flavipennis common. The ' Ent. Mo. Mag. 1898, p. 60. ' Cf. Trans. Norf. Nat. Soc. 1902, p. 332. ' Since the above was written I have been so tortunate as to capture somewhat commonly Deltocephalus formosus, a species not hitherto noticed jn Britain, in a marshy wood at Brandon, on the banks of the Little Ouse, which forms the north-west boundary of the county (Cf. Ent. Mo. Mag. 1908, p. 59). — C. M. I 145 19
