Show 1899.] PHYTOPHAGOUS COLEOPTERA OF AFRICA. 349 Hab. Boma, Congo (coll. Belgian Mus. and my own). This small species differs from Thrymnes nucleus Weise in the flavous head and differently coloured antennas and legs and nearly impunctate upper surface, aud from T. custos likewise in the flavous head and scutellum. T. bifoveatus Weise is black below and has two elytral foveas. PODAGRICA(?) GLABRATA, sp. n. Ovate, widened posteriorly, flavous, the apical joints of the antennas and the elytra, breast, and abdomen black; thorax with a distinct transverse sulcus, impunctate; elytra not perceptibly punctured. Length 3 millim. Head impunctate, flavous, the frontal tubercles small, clypeus widened between the antennas, apical joint of the palpi acute; antennas filiform, extending to the middle of the elytra, flavous, the last four joints blackish ; thorax transverse, tAvice as broad as long, the lateral margins distinctly rounded, the posterior angles produced into a small tooth, tbe surface strongly transversely convex, flavous, shining and impunctate, the base with a distinct transverse sulcus, which does not extend to the sides but is bounded laterally by perpendicular grooves or rather turns downwards to the base, another small transA'erse depression is placed near the anterior angles; scutellum small, black ; elytra strongly convex and widened behind, much wider at the base than the thorax, black, shining, with traces of a few extremely minute punctures, only visible with a very strong lens here and there ; legs flavous, all the tibias with a minute spine; the breast and abdomen black; prosternum moderately broad, elongate; the anterior coxal cavities closed. Hab. Malvern, Natal (G. Marshall). This small species differs from the typical form of Podagrica in its more convex and ovate shape and in the thoracic transverse sulcus. In the absence of other similarly structured species, hoAvever, I have for the present included the insect in Podagrica, to which at all eA'ents it is very closely allied. The elytra have a very narrow lateral reflexed margin, which is accompanied by a row of punctures, the only ones visible; the metatarsus of the posterior legs is as long as the following two joints together. CREPIDODERA ZAMBIENSIS, sp. n. Elongate, fulvous ; head and thorax remotely and strongly punctured, the latter transversely sulcate ; elytra dark blue, strongly punctured, the interstices longitudinally costate throughout. Length 5 millim. Of elongate and parallel shape, tbe head broad, strongly and remotely punctured at the vertex, the latter fulvous, lower portion of the face paler; frontal tubercles in shape of narrow transverse ridges, clypeus with an acute central ridge ; antennas rather long and slender, fulvous, the basal joint elongate, thickened at the |
