 INSECTS Since the above paragraph was written I have been doing some desultory work on this family, and consider the determination of the following local species sufficiently satisfactory for publication : — Eucharii adscendem, Fab., the only British exponent of its family, was swept in Tuddenham Fen on 6 May 1907. Males of Eurytoma aterrima, Sch., at Brandon on 27 September 1907, and o{ E. nitida, Walk., at Barton Mills on 12 June 1 900. Isosoma longicornis, Walk., at Bentley Woods on 21 June 1901 ; /. brevis, Walk., at Southwold on 31 May 1905 ; /. angustlpennis, Walk., at Bentley on 13 May 1900, and in Tuddenham Fen on 6 May 1907 ; /. minor. Walk., at Belstead on 23 May 1896 ; /. elongata, Walk., at Foxhall on 27 May 1907 ; /. angustata. Walk., at Barnby Broad on 5 July 1906 ; /. depressa, Walk., swept from grass at Nacton 26 May 1 900 ; and /, attenuata. Walk., at Wortham on 9 June 1900. Callimome curtus, Walk., was beaten from birch in the Bentley Woods on 4 May 1895, and is frequently common on the underside of lime leaves in my garden here at Monk Soham ; C, Jlavipes, Walk., was found on Angelica flowers at Claydon Bridge on 10 August 1899 ; and C. chloromerus, Walk., in the Bentley Woods on 13 May 1900. Mr. Tuck has taken at Tostock several specimens of the interesting Monodontomerus nitidus, Newp., which lives in bees' nests. Two species of Chalcids were described by Rev. W. Kirby,'**^ Ma- croglenes penetrans and Eulophm damicornis. I have recently been engaged upon the compilation of a Catalogue of British Chalcididae, shortly to be published by the Entomological Society, and find that upon the closest scrutiny there appear to be 1,408 species in our isles. Cynipidae Of this family we have a much more representative, though still quite an elementary, list, and one which could with ease be extended with a little attentive working. Though a large proportion of these insects are phytophagous in their habits, they have nothing in common with the Tcnthre- donidea structually, and many are known to be parasitic upon Aphides. The majority, however, construct galls upon the leaves and roots of herbage and trees which were for long, and still are by the vulgar, supposed to be of vegetable origin ; many are inquiline in the galls of their relatives ; and several harbour commensals which play no part in the galls' construction. I am much indebted to Mr. G. C. Bignell for assisting me in the determination of the following thirty-three species, of which only one was noticed by the older collectors. The curious and distinct species of Eigites, Kkditoma, and Eucoela are not uncommon from June to November ; Figites scute/Iaris, Rossi., has been found at Marlesford, and Anacharis tincta, Walk., in Tuddenham Fen ; Kleditoma nigra, Htg., in the Bentley Woods ; and Aegilipes rufipes, Westw., by Tuck about Tostock, and by Flatten in Ipswich. The extensive genus Eucoela is represented by E. nigricornis. Cam., common at Mildenhall, Claydon, and Bury on carrot flowers ; E. proximo. Cam., at Framlingham in June ; E. diaphana, Htg., at Burgh Castle and Bentley ; E. crassiscornis, Westw., found about Bury by Tuck, and E. gracilicomis, in the Bramford marshes. What are, perhaps, E. rapae, Westw., and E. testaceipes. Cam., have been seen respectively at Bentley and Foxhall. The large and very rare Ibalia cultellator, Fab., was first taken in Britain by Mr. W. H. C. Edwards, who captured a male flying in his garden at Bungay ; this specimen is figured by Curtis ; ^ and is said to be parasitic upon Sirex juvencus. The galls of Cynips kollari, Htg., are common everywhere upon oak trees ; but Andricus radicis. Fab., is more often met with in the perfect state and frequently swept from herbage in Bentley Woods ; the galls of A. fecundatrix, Htg., may be commonly observed in the same locality, where I once found A. Sieboldi, Htg., and probably also A. gemmatus, Adl. ; Synergus Reinhardi, Mayr, inquiline upon C. Kollari, is very common ; S. Hayneanus, Htg., occurred to me at Foxhall in June 1895 ; S. incrassatus, Htg., inquiline upon Aphilothrix corticus, Htg., is common, the pretty males having been found at Bentley and about Bury ; and both S. vulgaris, Htg., and S. melanopus, Htg., are common. The imagines of Aphilothrix quadrilineatus, Htg., occur in Bentley Woods, where I have met with Trigonaspis megaptera, Panz. Biorrhixa terminalis. Fab., is found at Belstead and Ipswich in November, and both Neuroterus lenticularis, Oliv., and iV. aprilinus, Gir., are abundant, but N. tricolor, Htg., has only once been noted in the Bentley Woods, where I have seen galls of N. numismatis, Oliv., Andricus ostreus, Gir., and Dryophanta divisa, Htg. The woolly bedeguar galls of Rhodites rosae are not uncommon about Bentley and Wrentham ; and I have taken the much rarer R. nervosus. Curt., at Framlingham in June. Allotria pedestris. Curt., and A. megaptera. Cam., were found at Brandon in June 1903 ; I have observed galls of Diastrophus rubi on blackberry at Debenham, and Mr. Rasor has sent me those of Aulax glechomae, Htg., from Woolpit. '°* Trans.
