INSECTS Elipsocus unipunctatui is not uncommon at Brandon, Whitton, and the Bentley Woods ; E. hyalinus at Monk Soham, Bentley Woods, and Tuddenham Fen ; E. TVestwoodi has occurred to me at Box- ford and Tuddenham in July ; and E. abieth is everywhere common on fir trees, upon which four specimens of £■. fy<7«o/ij, Rost., are recorded from Tuddenham Heath at the end of June 1880.'* Recently E.Jlaviceps and E. consimi/is, both from Foxhall, have been added to our list, together with Ectopsocus Brigsii from Wherstead and the Bentley Woods in March, as well as Peripsocus albogut- tatus in September and August in Tuddenham Fen, and P. phaeopterus at Brandon. Much remains to be done among the Perlidae, of which the record of even Chloroperla grammatica is not positive, though I believe I took it here in 1893. Leuctra fusciventris has been swept at Foxhall and Wher- stead, where L. Klapahki is not rare on alder in the autumn ; and L. genkulata has been found at Brandon Staunch in September. Nemoura variegata is common, especially in the early spring, at Bentley and Aspall Woods, Sotherton, Barham, Ickworth, Sudbury, and Tuddenham. N. cinerea has once been found about Ipswich, but N. incomptcua occurs in the Bentley Woods and Bixley Decoy annually in April, and sometimes again in September, when N. praecox may also be found in the latter locality. Mayflies are often common, but there appears to be but very small variety among them ; Ephemera vulgata is very rarely as abundant here as in other counties where I have observed it ; Leptophlebia marginata has only turned up once, on the banks of the Gipping in May, though quite possibly it constantly occurs there ; L. iubmarginata is rarely noticed at Foxhall in the same month. Cloeon dipterum is by no means uncommon in Southwold, Assington, Shrubland Park, and Mr. Chitty once took C. simile at Brandon in June ; though the ubiquitous Baetis Rhodani is everywhere met with. Among the Odonata, or dragon-flies, we are able to instance most of the commoner kinds as of indigenous occurrence. Sympetrum striolaium is common, S. flaveolum flies in Tuddenham Fen in August, but has not been seen elsewhere ; Platetrum depressum is not very common, though widely distributed ; Libellula quadrimaculatum has occurred to me in the marshes at Beccles, to Prest near Lowestoft, and to Paget rarely at Lound. Of the very rare and local L.fulva I captured an example in the marshes at Beccles in 1892,' another in Barnby Broad in July 1905 ; and Paget records it from Lound. Orthetrum caerulescens I saw abundantly on the outskirts of Henham Park, Covehithe, and at Hulver Bridge in 1900 ; and 0. cancellatum is nearly certain to be found in the broads of the north-east, since I have noticed it in Wroxham Broad in Norfolk. Cordulia aenea is said to be rare in Fritton Wood in May, and has several times been mentioned from Martlesham Heath ; Brachytron pratense is recorded by Lucas from the Lowestoft Broads, and I found it at Hen- stead in 1905. Harwood has found the rare Aeschna mixta flying over the Stour at Wiston, and I took an example in a Beccles house m 1892 ; * another has occurred to me in an Ipswich garden in October ; and it is very probable that Paget's A. varia. Curt., is also referable to this species. Aeschna cyanea and A.grandis are both quite common.' Both kinds of Calopteryx have turned up and Fitch reports great numbers of C.virgo near the source of the Stour.* The smaller dragon-flies have been much neglected. Lestes sponsa at Westleton, Claydon, Oulton, and Barnby Broads ; Platycnemis prnnipes at Blakenham, Claydon, Bentley Woods, Sproughton, and Bures ; with the common Pyrrhosoma nymphula and Ischnura elegans have been noted. Erythromma najas, at present uninstanced, certainly only requires a little searching in June to put in an appearance. Agrion pul- chellum at Brandon, Lowestoft, and Tuddenham Fen, and A. cyanthigerum at Blakenham, Claydon, and Barnby Broad are uncommon, though A. puella swarms everywhere from Lakenheath and Wortham to Nayland and the coast salt-marshes. The Neuroptera-plannipennia, regarded by Prof. Miall as the true representatives of the Order, are in very fair profusion in Suffolk, where Sialis lutaria swarms. The curious snake-fly, Raphidia notata, occurs sparingly in Belstead Wood and Assington Thicks, which, though 30 miles apart, have a wonderfully analogous fauna ; upon one occasion I bred this species from a larva found in burrows in a solid holly stem. R. xanthostigma has occurred to me singly at Brandon, and in a very wet part of Tuddenham Fen in June. Sisyra fuscata is ohcn common by running water ; Micromusvarie- gatus occurs at Stanstead, Tuddenham, and Bentley Woods, where, as well as at Wherstead, M. paganus has been found. The pretty genus Hemerobius is well represented by H. nitidulus on pine trees in Bentley Woods, H. humuli commonly, H. lutescens at Belstead and Harleston, H. limbatus common from Brandon to Ipswich, H. stigma abundant in Belstead Woods, and beaten from pine-hedges at Elvcden and Tuddenham in August, H. subnebulosus occasionally at electric light, &c., about Ipswich and Lowestoft ; H. nervosus once found at Bentley in May, and H. concinnus beaten from fir in the same locality at the end of June. At Kessingland I have swept H. micans among marram grass. • Ent. Mo. Mag. xvii, 21,71. ' Ibid. 1897, p. 106. * Ibid.
