Two of the specimens are finely preserved, showing the dorsal view of the body, antennae, part of legs, and most of both pairs of wings. It is a very large species and probably belongs to the subgenus Stenich- neumon Thomson, to judge from its robust build and thickset, taper- ing antennae with short joints. The cubito-discoidal cell appears to be somewhat longer in the type specimen, but I think all are undoubt- edly the same species. The discocubital vein is without trace of the stump of a vein which is present more or less distinctly in all recent species. Ichneumon obdtjratus, sp. nov. (Fig. 23.) Female. Length about 8 mm. Black, legs varied with rufous or ferrugi- nous. Head rather small, more or less subquadrate, its surface subshining. Antennae involute, the basal joints about twice as long as thick and the apical ones more or less quadrate; flagellum apparently without pale annulus. Mesonotum microscopically sculptured, subopaque; parapsidal furrows not defined. Scutellum with a broad transverse depression at its base; its surface moderately convex and with scarcely evident raised lateral margins. Areola of metanotum large, hexagonal, the basal and middle lateral areas sepa- rated. Abdomen black, the post- petiole distinctly punctate. Legs ru- Fig. 23.—Ichneumon obduratus, sp. fous or ferruginous, including the coxae. nov* TyPe- Wings hyaline, veins fuscous, the sub- median cell considerably longer than the median, the transverse median vein but little oblique. Discocubital vein evenly and strongly curved, without trace of any stump of a vein. Areolet of moderate size, very narrow above; stigma narrow, black with pale base; marginal cell long, the second sect
