INSECTS 



await determination. The rare Polemon liparae has been swept in the marshes at Barton Mills in 

 the middle of June, and Dale also tells us that it has been bred from the dipterous Lipara 

 lucms at Beccles in 1861."' 



The Pezomachoid Chasmodon apterus is found at Wherstead and Blythburgh ; and Aphaereta 

 cephaloUi in the Bentley Woods and ovipositing in dipterous larvae in dung at Southwold. Goniarcha 

 lucicola occurs among autumnal fiingi at Bramford and Foxhall ; and Dtaspasta contracta in a damp wood 

 in the former locality in mid-October. The typical Alysla manducator is frequently found ovipositincr 

 in dipterous larvae amongst carrion at Claydon, Foxhall, Henstead, Barnby Broad, and Tuddenham 

 Fen ; the allied Homophyla pullata I have seen in a horse-trough in Ipswich, Phaenocarpa conspurcator 

 ovipositing in dog's droppings, Aspilota ruficornis in Stanstead Wood and Tuddenham Fen, and 

 once I found several specimens of what the Rev. T. A. Marshall said was A. macu/ipes in a fungus 

 at Assington Thicks in June. At the same locality Oenone ringens has also been taken ; and the 

 curious Chaenon anceps is not uncommon at Tostock, Tuddenham, and Lowestoft. Coelinius niger 

 occurs frequently in marshes at Felixstowe, Dennington, and Barton Mills ; C. gracilis at Brandon ; 

 and C. elegans is doubtless common in the Broads district. Rhizarcha stramineipes has several 

 times been taken in the Bentley Woods, and Dacnusa abdita once or twice at Nacton. 



Proctotrypidae 



Very little is known of the British Proctotrypidae, which have never been adequately mono- 

 graphed ; and consequently I am greatly indebted to the late Rev. T. A. Marshall, whose contribu- 

 tion on this subject was, I believe, to have appeared in Andre's great Species des Hyminoptires 

 d'Europe, for kindly examining and naming the fifty kinds enumerated in the following list, only 

 two of which had been previously recorded hence by Curtis. These interesting little creatures are, 

 for the most part, parasitic upon the eggs of other insects and, since more than one often find 

 sustenence in a single moth's egg to supply the whole of their larval appetite, the minute size of 

 these ' Fairy Flies ' may be easily imagined ; but their beautiful and varied structure is only to be 

 appreciated through the microscope. Their classification is still to a great extent in a state of chaos, 

 from which it may be expected to emerge on the completion of Dr. KiefFer's perhaps too elaborate 

 European Monograph. We are indebted to Mr. A. J. Chitty for the revision of our species, and 

 those not here bearing a distinctive name will shortly be described by him. 



In the subfamily Proctotrypinae, the typical genus is represented in Suffolk by Proctotrypes 

 niger, which has occurred to me in Tuddenham Fen and to Tuck at Tostock ; its var. a was swept 

 at Needham Market, and the var. /3 taken on umbelliferous flowers on the coast at Felixstowe. 

 Tuck has also taken P. ater, Nees, at Tostock in May and P. buccatus, Thoms., in September ; I 

 have found the latter at Whitton and Dodnash. The first of Mr. Chitty 's new species was also 

 taken by Tuck in an old beehive in Bury St. Edmunds, and I discovered the second in a dead 

 rabbit in the Bentley Woods.^* P. kngicornis, Nees, is common, and has turned up at Bentley 

 Woods on fir trees, at Felixstowe, Claydon, and Aspall Wood. P. brevipennis, Latr., was once 

 swept at Westleton by Mr. Elliott, and I caught it running on Foxhall Plateau in July 1904. The 

 handsome P. gravidator, L., is not uncommon at Foxhall, Brandon, Herringswell, Belstead, and on 

 the Kessingland cliffs ; whilst an allied species — Chitty 's third — was in my sweep-net in Tuddenham 

 Fen on 23 August 1905. P.pallidipes has only been found at Wherstead and Barton Mills ; and 

 P. viator, which destroys wireworms, at Ipswich and Tostock. P. calcar, Hal., is also found at 

 Tostock and Barton Mills ; but P. laricis, Hal., is confined to the Ipswich district, Bentley Woods, 

 Bramford, and Bourne Bridge. It is P. parvulus, Hal., that destroys the larvae of Orchesia micans 

 in fungi on elm, in the same locality. Chitty's fourth species I swept in a little alder wood at 

 Bramford ; ^' and his fifth occurred to me on long grass at Wortham early in June 1 900. Codrus 

 apterogynus, Hal., and Lagynodes palUdus, Boh., are not infrequent, the former at Southwold, Corton 

 cliffs, Sproughton, and Claydon, the latter in the Bramford marshes and amongst moss. Tricho- 

 steresis nitida. Thorns., has been taken at Nacton ; T. Forsteri, Kief., swept at Southwold in August 

 1904; Megaspilus alutaceus, Thoms., on the cliffs at Corton; M. halteratus. Boh., in the Bentley 

 Woods ; M. rufipes, Nees, among moss at Ipswich ; and the apterous form of M. thoracicus, Nees, 

 in a marshy wood at Bramford. The interesting and perhaps fossorial Bethylus fuscicornis, Jur., is 

 recorded by Curtis, under the name B. punctatus^^ from rushes on the beach at Covehithe, and it is 

 common at Ipswich, Bentley Woods, and Oulton Broad ; its for-long-intermixed cousin, B. cepha- 

 lotes, Forst., has been taken at Brandon in the north and Sudbury in the south. Of the Dryininae, 

 Chitty has recorded '^ Gonatopus striatus. Kief., from Brandon in May, and G. sepsoides, Westw., 

 from Lowestoft. To the genus Antaean he has paid considerable attention, and has just published
