From all of these Odontiomorpha is at once distinguished by the distinct thoracic sulcus, a rather rare character amongst the Eumolpidce; the terminal short and dilated joints of the antennae and the emarginate apex of the intermediate tibiae will further assist iu the recognition of tbe genus. Only a single, very small specimen was sent by M r . G. Marshall. ODONTIOMORPHA MINUTA, sp. n. (Plate XX. fig. 6.) Black, the basal joints of tbe antennae and the legs fulvous; above aeueous or obscure cupreous ; head and thorax closely punctured ; elytra strongly punctured in irregular rows, the interstices costate at the sides. Length 2 millim. Head finely and rather closely punctured, the clypeus not separated from the face, its anterior edge concave ; labrum and palpi fulvous ; antennae scarcely extending to the middle of the elytra, fulvous, the apical five joints black, the second joint scarcely shorter than the basal one and similarly thickened, the third as long but thinner, apical joints widened : thorax strongly transverse, twice as broad as long, the sides strongly rounded, the surface with a distinct transverse sulcus, slightly interrupted at the middle, closely and strongly punctured ; scutellum with the apex truncate; elytra stongly convex and slightly widened towards the apex, distinctly transversely depressed below the base, the shoulders prominent, the punctation strong and close, arranged in semiregular lines, tbe interstices near the lateral margins longitudinally costate ; underside black, legs fulvous. Hab. Malvern, Natal (67. Marshall). PAUSIRIS SUBFASCIATUS, sp. n. Cupreous, the antennae and the tibiae fulvous ; head and thorax closely and finely punctured, sparingly covered with white pubescence ; elytra finely and semiregularly punctured, with white hairs arranged in two more or less distinct transverse bands at the base and near the apex. Length 3 millim. Of ovate posteriorly slightly dilated shape; the head very finely and remotely punctured, the interstices furnished with very short single white hairs ; antennae extending to the base of the elytra, fulvous, the terminal five joints strongly widened ; thorax about one half broader than long, the sides rounded, w-ith a narrow margin, the anterior portion not more constricted than the posterior one, the disc punctured like the head, cupreous, the interstices at the sides and at the middle with some longish w"hite hairs; scutellum subpentagonal, closely pubescent; elytra wider at the base than the thorax, shoulders prominent with a shallow transverse depression below the base, more strongly and closely punctured than the thorax, the punctures arranged in irregular rows, the surface with an indistinct band of white hairs at the base and another at the apex cupreous ; below greenish-cupreous, sparingly |
