A HISTORY OF WARWICKSHIRE species of water beetles occur in the adjoining counties which have not yet been recorded from Warwickshire. Of the Brachelytra a large number of species occur at Cannock Chase, Bewdley, Sherwood Forest, Church Stretton, Trench Woods and Budde'n Woods which have not been found in our county, and of the other sections the following insects may perhaps be mentioned : Triplax russtca and eenea, Teredus nitiaus, Gnathoncus rotunaatus, Plagaderus dissec- fus, Thymalus limbatus, Antheropbagus nigricornis, Byrrbus fasciatus and dorsalis, Georyssus pygnuzus^ Macronycbus quadrituberculatus, Trox sabulosus, Elater coccineus and pomorum, Athous rhombeus, Clytus mysficus, Pachyta collaris and octomaculata, Strangalia quadrifaciata and nigra, Melasoma ceneum, Tropideres sepzco/a, Apion jilirostre, and some hundreds of others which cannot be referred to. Warwickshire has however produced a fairly large number of species when compared to other counties. It has been said that the midlands are not productive of a large and varied insect fauna, and that in the British Isles the further west investigations are made the less insect life appears to thrive. While to a certain extent this may be true, it is nevertheless a fact that the more a district is worked the more species does it reveal. It is of course impossible to make a county list of Coleoptera com- plete, as at any time further species may be found in the district. The Rev. J. H. Bloom of Whitchurch Rectory in the space of a few months last year added several species to our county fauna by collecting in the neighbourhood of Stratford-on-Avon. Mention has been made of some of the more remarkable beetles which occur in the immediate neighbourhood, but which have not been recorded from the county, and the following remarks regarding the families and more notable species which have appeared within our limits may be interesting. Of the Geodephaga, which embraces 310 British species, we find 138 occurring in Warwickshire. The beautiful species Cicindela campestris, which is very active and voracious, is extremely abundant at certain seasons, and the elegant beetle Cychrus rostratus is occasionally taken throughout the district. Five species of Carabus, four of Notiophilus and four of Leistus occur. Elapbrus riparius and E. cupreus, both very beautiful insects, may sometimes be taken in the utmost profusion on mud flats near streams and ponds. Clivina collaris, Badister sodalis, Chlcenius vestitus, C. nigri- cornis and Oodes helopioides occur but sparingly in a few localities. The genera Harpalus and Pterostichus are fairly well represented, and the commoner species of Amara are numerous. The rarer ones, A. ovata, A. acuminata and A. nitiaa, occur in certain localities. Taphria nrualis has turned up occasionally at Knowle. Fifteen species of the genus Ancbomenus occur, amongst which may be mentioned A. marginatus, which is common locally ; A. graci/is, A. thoreyi and A. puellus. 78
