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.
