Show 556 MR. M. JACOBY ON T H E [May 18, transverse in the female, the sides very slightly rounded at the middle, the anterior angles oblique, forming a tooth at some distance from the middle, the surface finely granulate and closely and finely punctured ; elytra widened towards the middle, each apex rounded, the surface slightly more strongly punctured than the thorax, the punctures closely arranged in irregular rows; posterior tibiae distinctly toothed at their upper margins, their metatarsus shorter than half the length of the tibias, posterior portion of the hind femora black. Hab. Mashonaland (67. Marshall). British Museum and my collection. This Longltarsus does not differ in any striking way from many of its European congeners in general appearance and sculpture ; the absence of wings, the uniformly coloured antennae, and the partly black posterior femora will, however, help in its recognition. The posterior tibias have a distinct and rather robust spine. LONGITARSUS BIANGULATUS, n. Sp. Winged, piceous below, above obscure fulvous, antennae and legs flavous ; sides of thorax biangulate, surface closely punctured; elytra closely, distinctly, and semiregularly punctured. Length |-1 line. Head obscure piceous or fulvous, impunctate, opaque, frontal tubercles absent, carina acute and sharply defined, forming a sharp ridge at the middle; antennae two-thirds the length of the body, flavous, the first joint long and slender, the second scarcely shorter than the third joint, the following more elongate; thorax one-half broader than long, the anterior angles strongly oblique, forming a thickened angle near tbe middle, and followed by a semi-distinct tooth below the latter, the surface finely and closely impressed with somewhat elongate punctures, the interstices minutely granulate, obscure fulvous, opaque ; elytra more strongly punctured than the thorax, the punctures arranged in closely approached rather regular rows : the underside and the posterior femora more or less piceous ; rest of the legs flavous, the metatarsus of the posterior legs half the length of the tibias. Hab. Mashonaland (67. Marshall). British Museum and my collection. A species of more dusky fulvous colour, which may be known by the acutely raised carina of the head and the obsolete second angle at the sides of the thorax, more distinct in some specimens than in others. S E R R A P H U L A , n. gen. Body ovate, apterous; antennas filiform, frontal elevations strongly raised ; thorax subquadrate, without depressions ; elytra punctate-striate; legs robust, the posterior femora very strongly dilated, their tibias widened at the apex, the latter mucronate and furnished with a long serrate prolongation scarcely shorter than the tibia itself; tarsi inserted above the apex of tbe tibias; the |
