Periclista, Knw.—This name was proposed by Knonow in his monograph of the European Blenocampids, published in the “Winer Ent. Zeit.,” V. 1886, 186, for those species having the lanceolate cell petiolate, the eyes more or less remote from the bases of the mandibles, and the posterior wings with the outer cells closed by a marginal vein. This name had already been used by Forester, 1869, tor a genus of Cynipidæ, and I therefore propose the name Mogerus (μογερός) to take its place.
