Locality. Chagos Islands : Salomon Atoll, lie de Passe; bred from mines in Sccevola Koenigii (1905). Leucopis, Meigen. Leucopis Meigen, Syst. Beschr., xi. (1830), p. 133. 58. Leucopis griseola (Fallen), Dipt. Suec, Agromyz., (1823), p. 8 [Anthomyzd]. There is a fairly long series of a species of this genus; they exhibit no structural differences from the above species, but are on the average somewhat smaller in size, being from 1^- to If mm. long. The legs are not quite so definitely coloured and the third antennal joint is in most cases slightly larger. It is impossible to separate the specimens satisfactorily from the members of the series of L. griseola, in the Cambridge Museum. Localities. Seychelles. Silhouette: Mare aux Cochons plateau and forest above, IX. 1908; Mahe: country above Port Claud, 500—800 ft., 5. XI. 1908; Port Victoria, XII. 1908; Cascade Estate, about 1000 ft.; Anonyme Island, I. 1909; marshes on coastal plain, Anse aux Pins and Anse Royale, I. 1909. Also known from the Canary Islands.
