for Roesel's Bush Cricket which seems to show a preference for the east coast". They may well have recorded the same individual. In 1920 William John Lucas produced his monograph of the British Orthoptera, a book of over 250 pages with 25 plates, some of which were in colour; it listed all known British localities, species by species. Essex had its share of publicity and inevitably M. roeselii was well to the fore. By this time, the species had been found in few localities outside of the Thames Estuary. Lucas gave an account of the exchange of the insect between B.S. Harwood and himself previously mentioned, as well as detail of a A.B. Luvoni adding two new localities for the insect at Westcliff and Canvey Island between 21st July and 22nd September 1912. Other species mentioned by Lucas in his publication of 1920 were: Meconema thalassinum - Epping Forest (Shaw): Epping Forest near Chingford (Campion): Theydon Bois (Milton): Colchester (Harwood). Leptophyes punctatissima - Colchester (Harwood). Conocephalus dorsalis - Walton-on-the-Naze (Yerbury): north Essex Coast (Harwood): Near Clacton, macropterous form (Harwood). Phasgonura viridissima - Colchester (Harwood): Southend (Powers): Westcliff (Luvoni). Pholidoptera griseoaptera - Near Maldon (Fitch): Westcliff (Luvoni): Colchester (Harwood). Metrioptera albopunctata - Colchester (Harwood). Tetrix bipunctatus - Colchester (Ansorge). Acheta domesticus - In houses Walthamstow (Campion): In bakehouse, Colchester (Harwood). Stenobothrus elegans - Harwood found it on sea walls at Colchester whilst Yerbury discovered it in a Saltmarsh at Walton-on-the-Naze. A further record was at Leigh-on-Sea (Briggs). Stauroderus bicolor - Strawberry Hill Loughton (Campion): Epping Forest (Campion): Colchester (Harwood). Stenobothrus parallelus - Epping Forest (Shaw): Colchester (Harwood).
