4 [January, A NEW SPECIES OF MICEOQASTEE. BY CLAUDE MORLEY, F.E.S., &c. MlCROGASTEIt SUFFOLCIENSIS, Sp. 11. Niger, pubescens ; metanoto glabro, sec/mentis abdominis prima et se-cundo testaceis lateralis, his lineis duabus impress-is, oblique ex angulis apiralibus versus medium bans ascendentibus instrueta. Head black, dull ; labrum and palpi flavous, mandibles darker ; clypeus circu-larly separated from the face, broadly rounded in front, sparingly punctate and diffusely pubescent ; face punctate, covered with long scanty white hairs, longitu-dinally indistinctly carinated in the centre. Antennae gradually attenuated from base to apex, pilose, the joints cylindrical ; black, somewhat piceous beneath. Mesonotum shining, closely and finely punctate and pubescent ; mesopleura? brilliant, obsoletely punctate with scattered pubescence. Metanotum glabrous, broader than long, subrectangular ; centrally canaliculate and transversely strigose. Scutelluni very flat, brilliant, obsoletely punctate and pubescent. Abdomen subparallel-sided, dorsally deplanate, nearly smooth, with scattered white hairs ; first segment slightly longer than broad, with strong raised testaceous lateral margins, each of which in its basal half bears about fifteen long white radiant setae ; these margins become broader apically, and are separated from the central area by a linear depression ; central area basally depressed and glabrous, apically bifoveolate, subrugulose and pubescent ; second segment subrugulose, with smooth central tubercle, thrice broader than long, obliquely impressed, and thus forming a triangle at the anterior angles, which is testaceous ; third and fourth segments with distinct blue reflection in a strong light ; ventral surface laterally more or less testaceous ; terebra sub-exserted. Legs flavous ; hind pair slightly inflated, with the tibioa stramineous, cal-caria and base of tarsal joints whitish ; base of posterior coxae, apex of hind tibia; and tarsal joints, and extreme apex of hind femora, black. Wings hyaline throughout ; tegula and costa testaceous, stigma piceous, nervures in part fuscous. Length, ? , 3j mm. Wings, 8 mm. This species appears to be intermediate between the Rev. T. A. Marshall's Sections 1 and 2 (cf. Trans. Ent. Soc. Lond., 1885, p. 238 ; et Andre's Spp. Hyrnenop. d'Europe, tomes 4 and 5) ; it agrees with the former in having the terebra short, the wings hyaline, and the size small ; and with the latter in its broad, deplanate, basally rugose abdomen and slightly thickened hind legs. Its nearest ally is probably M. globatus (? L.), Nees, with which it agrees in the rugulose basal segments, fuscous belly, and rufous femora ; but it differs therefrom in the entirely pale palpi, abdomen ventrally testaceous at the sides, coxa? and trochanters more or less red, hind tarsi fuscous, with base of the joints broadly pale stramineous, mesonotum and pleura) closely and finely punctate and nitidulous, and the calcaria, which are hardly half as long as the metatarsus.
