The water beetles are pretty numerously represented in the district generally, the best localities for them being Coleshill, Sutton Park, Cannock Chase, and Bewdley. It must suffice to mention a few of the rarer or more striking kinds, _e.g._, _Brychius elevatus_, at Yardley and Knowle; _Haliplus cinereus_, at Knowle; _Hydroporus septentrionalis_, Bewdley; _H. marginatus_, Knowle; _H. picipes_, Cannock Chase; _H. lepidus_, Knowle, Bewdley, Cannock Chase; _H. duodecimpustulatus_, Bewdley; _H. assimilis_, Sutton Park, Knowle, Cannock Chase; _H. dorsalis_, Yardley, Knowle; _H. marginatus_, Knowle; _H. nigrita_, Knowle, Bewdley; _H. monticola_, Cannock Chase; _H. neglectus_, Cannock Chase; _H. umbrosus_, Knowle; _H. augustatus_, Knowle; _Ilybius ater_, Knowle, Cannock Chase; _I. guttiger_, Coleshill; _Agabus Solieri_, Knowle; _A. affinis_, Sutton Park; _Gyrinus caspius_, Hopwas; _Hydrobius picicrus_, Knowle; _Laccobius sinuatus_, Knowle; _L. alutaceus_, Knowle; _L. minutus_, Cannock Chase; _L. bipunctatus_, Cannock Chase; _Limnebius nitidus_, Knowle, Bewdley; _L. picinus_, Knowle; _Chætarthria seminulum_, Cannock Chase; _Helophorus æqualis_, Bewdley; _H.

Several of the Burying Beetles--Necrophorus and Silpha--occur generally in the district, as also do many of the Cholevæ. Colons are conspicuous by their absence--only two species having put in an appearance, viz: _Colon dentipes_, Knowle; and _C. brunneum_, Knowle. The interesting groups of Scydmænidæ and Pselaphidæ are remarkably well represented, but room can be found for only a few of the rarer species: _e.g._, _Scydmænus exilis_, Sutton Park, Hopwas Wood, Cannock Chase, Bewdley; _S. angulatus_, Cannock Chase; _S. hirticollis_, Sutton Park; _Eutheia plicata_, Budden Wood, _E.
