antennal joint is one-half longer than the penultimate. Body and legs densely covered with silvery pubescence. Abdomen sessile; its apical half densely punctured. Mesonotum trilobate, the parapsidal furrows being distinct.

Comes near to Rhynchochalcis, which may be known by the untoothed femora, by the scutellum being bilobate, by the frontal depression enclosing the anterior ocellus, and by there being a keel between the antennæ. The ovipositor is more distinctly separated from the abdomen than usual with the Chalcididina, being more as in the Torymine, that is to say the apical segments do not enter into its structure. I have included in the genus one species (C. bicornutus), in which the vertex is armed with 2 teeth or horns.

Dunbrody. Cape Colony.

The base and sides of the prothorax, the mesonotum round the scutellum; the sides of the latter are rufous. Face closely, strongly punctured. Frontal depression deep, closely striated, narrower than the space between it and the eyes. Hind ocelli separated from each other by double the distance they are from the eyes. Malar space as long as the eyes. Pronotum as long as the mesonotum ; its basal slope rufous, closely transversely striated. Pro- and mesonotum and scutellum covered with raised points in transverse rows; those on the scutellum are broader and larger. Metanotum reticulated; its areola is large, wide on the apical two-thirds, narrowed at the base; the sides of the segment are rounded at the apex and thickly covered with long, grey hair; their base bears laterally an oblique, stout tooth. Propleura smooth above; there is a curved keel below the middle. Central part of mesopleuræ closely reticulated; the base of the metapleuræ smooth, the rest strongly reticulated. Hind femora with seven teeth; the basal close together, the rest widely separated; the apical broad, rounded. Abdomen smooth, except the sixth segment, which is strongly punctured.

EURYCENTRUS, gen. nov.

3. Antennæ at least 12-jointed, the last joints not clearly separated, the third joint not much longer than the pedicle, covered

thickly with silvery tomentum; they are situated half-way between the eyes and the clypeus. Eyes densely pilose; the malar space is as long as them. Frontal depression gradually rounded, only margined at the eyes and, more distinctly, on the top above the fore ocellus. Scutellum large, clearly longer than wide, its apex broadly bidentate. Sides of metanotum stoutly toothed above, the teeth longer than the width at the base. Apical half of hind femora margined below, the margin slightly dilated at the base, bare. Hind tibiæ longer than the tarsi, not toothed at the apex; the basal four joints of the tarsi become gradually slightly shorter; the joints spinose. Abdomen short, the petiole very short, clearly broader than long; its apical segment strongly punctured, the others smooth; the ovipositor projecting, broad, three times longer than the width at the base. Wings smoky. Fore claws.

This genus, as regards the position of the antennæ, is intermediate between the Chalcidini and the Haltichellini, they being too low down for the former and not near enough to the mouth for the latter. The only genera with hairy eyes are Trichochalcis, Microchalcis, and Allochalcis, described by Kieffer (Berlin, Ent. Zeit., xliv., 246 and 247), but the species cannot fit into them. Trichiochalcis and Allochalcis are from Madagascar. The present genus comes nearest to the latter.

EURYCENTRUS ERYTHROGASTER, sp. nov.

Black; the abdomen, except the ovipositor, the four anterior legs except the coxæ and trochanters and the hind femora, red; the wings fuscous violaceous, the nervures black.

Length to end of ovipositor 10.5 mm.
Cape Colony.

f.

Head rugosely punctured, the centre of the front closely transversely striated; the temples and cheeks densely covered with longish silvery pubescence. Face below bordered by a smooth, shining keel, with rounded edges; the apex of clypeus bordered by a similar keel, but not so strongly projecting; the labrum large, with three stout transverse keels. Temples keeled on the outer edge. Malar space with two fine keels down the middle; they are united below and, on the outer side, above are bordered by a row of three foveæ, outside of which is another foveated band, extending to the bottom. Pro- and meso-thorax closely, rugosely punctured, more or less reticulated. The reticulatous punctures are strong on the pronotum, stronger on the scutellum, and weaker on the base of the

mesonotum. On the centre of the metanotum are two areæ extending from the base to the apex; these are bordered by an area which is dilated in the middle on the outer side; at the sides at the base is a long curved area, widest below, with two stout keels opposite the spines, the base bearing also stout keels.

EUCHARINÆ.

STIBULASPIS, gen. nov.

Scutellum large, roundly narrowed behind, ending in two longish teeth about 3 or 4 times longer than wide; strongly longitudinally striated throughout. Metanotum with a steep slope, the sides broadly rounded, not tuberculate. Antennæ twelve-jointed, the fourth to ninth joints stoutly produced above, the projections longer than thick, gradually narrowed to a sharp point, the apical roundly narrowed at the apex, closely united to the penultimate, which is broader than long and shorter than the preceding; they are placed well upon the face, above the lower edge of the eyes. Malar space longer than the eyes. Clypeus bounded laterally by oblique furrows, but not from the face. Temples very short. Except on the metanotum the whole thorax is strongly striated. Abdominal petiole stout, twice longer than wide. Wings not extending much beyond the apex of the abdomen; the nervures as in Stibula. Legs slender, the femora narrowed towards the apex; metatarsus as long as the following three joints united. Claws curved, simple. Ovipositor slender. Mandibles curved, bidentate, the apical tooth long, curved, sharp-pointed, the sub-apical shorter and blunter.

The affinities of this genus are with Stibula, which may be known from it by the antennæ in both sexes being simple, neither serrate in the nor flabellate in the ; and both have a distinct hump-like elevation above the metapleuræ. In Stibula, too, the thorax is strongly punctured; in Stibulaspis it is as strongly striated. The form of the scutellum is the same in both, except that in Stibula the apical teeth are curved, not straight as in the present genus. In the

of Stibulaspis the abdominal petiole is longer, much longer than in the; the middle joints of the antennæ, instead of being stoutly serrate, are stoutly flabellate.

The history of the Eucharine is interesting. So far as it is known the species are parasites on ants. Cf. Cameron, Manchr. Memoirs, vol. 34, 1890-91, p. 5, where it is stated that Chalcura bedeli,
