Show 1899.] PHYTOPHAGOUS COLEOPTERA OF AFRICA. 375 (also having a basal black band); the colour of the antennas is not given, but only the last joint is mentioned as being black ; other detailed particulars in regard to structure are absent. Of the present insect I have seen three or four specimens kindly sent by Mr. Marshall. MONOLEPTA NIGRO-ORNATA, sp. n. (Plate XXI. fig. 12.) Rufous; the antennas (the last two joints excepted) and the tibiae and tarsi flavous : thorax finely aud closely punctured ; elytra of similar sculpture, rufous, a broad transverse band at the base and another beloAv the middle black. Length 5 millim. Of similar shape and size as the preceding species, also of nearly similar coloration ; the head with a feAV minute punctures, rufous ; the antennas long and slender, flavous, the apical two joints black, the second and third joints small, equal, the fourth as long as the basal one; thorax twice as broad as long, of usual shape, finely and closely punctured, rufous, shiuing ; scutellum rufous ; elytra punctured like the thorax, the base with a transverse black band, similar to the preceding species, and another band below the middle of the same width but of rather rounded shape near the suture; below and the femora fulvous, the tibias and tarsi flavous. Hab. Malvern, Natal (67. Marshall). I have received several exactly similarly coloured specimens of this species, which differs, besides the coloration, in the less transversely shaped and rufous, not flavous, thorax. MONOLEPTA OCTOMACULATA Jac. Of this Monolepta several specimens obtained at Frere, Natal, have been sent by M r . Marshall, in which the elytra are entirely without spots ; they differ in no other Avay whatever from the type, but may be known by the black vertex of the head and the similarly coloured tarsi and breast. MONOLEPTA CITRINELLA, sp. n. Elongate, convex, pale greenish flavous; the head and the breast pale fulvous; antennas long and slender; thorax and elytra extremely minutely punctured ; legs slender. Length 4-4^ millim. Head broad, obscure pale fulvous, scarcely perceptibly punctured, the frontal elevations indistinct, the clypeus rather strongly raised between tbe antennas; the eyes large and round; antennas nearly extending to the apex of the elytra, flavous, the terminal two or three joints fuscous at the apex, second and third joints small, equal, the basal and the other joints very elongate and slender; thorax nearly twice as broad as long, the lateral margins perfectly straight, the posterior margin rounded, anterior angles slightly obliquely truncate, the disc microscopically punctured ; scutellum pale fulvous; elytra very closely and slightly more distinctly punctured than the thorax, comrex, the sutural margin rather 25* |
