Hab. Salisbury, Mashonaland (67. Marshall). Distinct in its mode of coloration from any of its allies. CANDEZEA NIGROTIBIALIS, sp. n. Flavous, the antennas (the basal joints excepted) and the tibias and tarsi black ; thorax obsoletely sulcate, finely punctured; elytra more strongly and very closely punctured. Length 4 millim. Head impunctate, the eyes large, tbe frontal tubercles broad, as Avell as the clypeus ; antennas long and slender, black, the loAver three joints flavous, the second and third joints short, equal in the male, the third joint slightly longer in the female, the other joints very slender and elongate; thorax nearly twice as broad as long, of usual shape, the sides straight at the base, slightly rounded at the middle, the anterior angles slightly thickened, the surface obsoletely transversely sulcate, very minutely punctured; elytra wider at the base than the thorax, distinctly widened towards the middle and convex, extremely closely and more strongly punctured than the thorax, the interstices slightly wrinkled; beloAv and the femora flavous, the breast rather darker; tibias and tarsi black, tbe metatarsus of the posterior legs very elongate, all the tibiae mucronate ; elytral epipleuras distinctly continued beloAv the middle. Hab. Malvern, Natal (67. Marshall).
