 A HISTORY OF SUFFOLK Orihocephalus saltatory and, at Lowestoft, 0. mutabilis have been noticed here. Six kinds of Dicyphus (of which D. pallidkornis is confined to Digitalis purpurea at Freston), Campyloneura virgula^ and the two species of Cyllocoris are all common on their respective food-plants. Aetorhinus angulatus is often attracted to light at night ; and I have captured Glohiceps Jlavomaculatus, G. dispar, and Me- comma ambulans. Butler has taken a macropterous specimen of Cyrtorrhinus flaveolus at Fritton,' I have found C. caricis at Wherstead, and C. pygmaeus has occurred to Thouless at Fritton. Eleven species of the genus Orthoty/us have been found in Suffolk, of which O. prasinus, taken by Saunders at Southwold in 1877, 0. tenellus at Freston, and O. rubidus on Artemisia maritima are the only un- common ones. Hypsitylus bicolor, Heterocordylus tibialis, Onychumenus decolor, and Oncotylus viridiflavus are uncommon, and Heterotoina merioptera abundant on nettles. Loxops coccineus has only been seen at Kentford, with Malacoris chlorixans in the Bentley and Dodnash Woods. The two common Macrocolei and both the Macrotyli are met with ; Conostethus roseus is abundant upon Foxhall Plateau and Harpocera tboracica on oaks everywhere. Amblytylus affinis, Byrsoptera rufifrons, the three Phyli and Atractotomus magnicornis occur sparingly, though A. mali has only been found at Bungay upon one occasion in 1903. Eleven species of Psallus, among which P. alnicola at Freston and P. Roter- mundi at Brandon are very local, and six of Plagiognathus, of which P. albipennis is found on Artemisia maritima all along the coast, have been noticed. Butler took Asciodema obsoletum at Lowestoft in 1891 ; I have recently also turned it up about Ipswich. Many of the interesting aquatic Cryptocerata await discovery, and few unusual kinds have been noticed. Naucoris cimicoides is said by Paget to have been very common in ditches about Yarmouth in 1825 ; it occurs at Oulton Broad, Ipswich, in brackish water at Bawdsey, and swarms in the Tostocic ponds. Nepa cinerea, the water-scorpion, is generally common ; but the handsome Ranatra linearis stood on the authority of a single specimen taken many years ago at Battisford by Baker, till Tuck took several in one pond in the middle of a field at Drinkstone in October 1 901.* Notonecta glauca is abundant, and its vanety furcaia is referred to by Paget ; Plea minutissima occurs in all the ponds about Ipswich. Of the extensive genus Corixa, comprising the lesser waterboatmen, we have only fifteen kinds as far as is at present ascertained ; all these are fairly widely distributed, though C.fallenii is represented by only two individuals taken respectively in 1893 and 1904, C. cohoptrata and C. venusta are restricted to Bixley Decoy and Oulton Broad, and C. limitata is very rare and local. C. lugubris often occurs, mixed with C. praeusta, in the utmost abundance among shrimps, in the brackish ditches at Bawdsey, the net becoming weighed down with a dark mass of them. From this short resume of the Heteroptera it will be seen that some two hundred and eighty- four species have been noticed in Suffolk. Considering that I captured over a hundred in 1897 alone, and that less than that number have been added during the following eight years, it is sufficiently obvious that collecting of late has fallen into neglect, and that assiduous working might show up many new kinds. HOMOPTERa CiCADIDAE In this group we have had even less observations to draw from than was the case in the Heteroptera. Mr. Butler noted a few about Lowestoft in 1891, Mr. Edwards mentions one or two kinds from Southwold and Brandon, and Curtis records, I think, two from the county. It cannot, therefore, be wondered at that I have been able to include little more than exactly half the British kinds ; but, with our extensive marsh country, to which many of those insects are restricted, quite another fifty or sixty kinds should turn up if systematically sought in favourable situations and upon their particular food plants, for these, like the last group, are entirely phytophagous in their economy. The curious Centrotus cornutus is a common species on bushes in the woods about Ipswich, Bury St. Edmunds, and Lowestoft in June ; but Gargara genistae is very local at Tostock and Ipswich, though Mr. Norgate has taken it commonly on broom at Barnham and Downham in the north-west. Issus coleoptratus has only occurred singly at Ipswich in 1894 and 1904, and in a wasps' nest in a holly bush near Bury ; Cixius pilosus and C. nervosus are common, though C. cunicularis is decidedly local at Tostock and Assington Thicks in July. The thick-horned Asiraca clavicornis was first found by Curtis at Henstead near Wangford, and more recently by myself among coniferae in Bentley Woods, it is not uncommon about Brandon ; I have also found Delphax pulchella to be somewhat common on reeds in Benacre and Herringfleet Broads in the middle of August. The extensive genus Liburnia requires much more full investigation than it has hitherto received ; of the • Ent. Mo. Mag. 1891, p. 277. 'Cf. Tram. Norf. Nat. Soc. 1902, p. 333. 144
