Perlidia i 30 Ephemeridia, 5 39 Odonata, 22 42 Planipennia, 13 . . . . . . 55 Trichoptera, 25 ...... 163 (about) HYMENOPTERA The lists of the Cephidae, Tenthredinidae, Siricidae, Ichneumonidae and Chrysididae are due to Mr. Hamm, who has been assisted with names by the Rev. F. D. Morice and Mr. Claude Morley. Mr. Hamm is also responsible for the compilation of the Aculeata lists, in which he has been largely helped by Mr. W. Barnes, who has drawn up a very good list from the Reading district. Mrs. Cope (formerly Miss Thoyts) has contributed a good list from Sulhamstead, and Mr. L. Young a useful list from Bradfield. Mr. Harwood has also recorded a few species from the Maidenhead district; and we are greatly indebted to Mr. E. Saunders, F.R.S., for his kindness in naming and verifying many doubtful species in this group. 74 1
