M A R T I N J A C O B Y ox [Feb. 16, followed by the deep transverse sulcus, anterior angles tuberculate, the sides from the middle to the tubercles obliquely diverging, the surface impunctate, with the exception of a few minute punctures at the middle of tlxe disc, tlxe latter with two fovea?, one at each side before the middle, and joined at the latter place by a feeble curved gx-oove, only visible in certain positions; elytra sub-cylindrical, feebly depressed below the base near the suture, the shoulders rounded, the punctures closely placed and moderately sti'oxxg, much finer towards the apex, tlxe ninth row entire, interstices flat and impunctate except near the apex where they are raised ; below and the legs black, finely pubescent. Hah. Mashonaland (my collection). This is another of the smaller-sized blue species, closely allied to L. azurect Lac, but differing in the curved antemedian depression of tlxe thorax which ends in a fovea at each side; from L. suahilornm Weise, the absence of the deep elytra! depression, the frontal tubercles of the head, and the larger size will separate the species. L. acutangula Weise has the antenna? and the tibia? and tarsi more or less testaceous, also a punctured thorax, and L.fugax Weise has likewise a closely-punctured thorax and is of smaller genex-al size. LEMA GRAMINIS, sp. n. Below, tlxe head, antenna? and the tarsi black, above testaceous, antenxxa? short; thorax subcylindrical, scarcely constricted, impunctate ; elytra closely punctate-striate; scutellum black. Length 3| millim. Head flat, black, sparingly pubescent, the eyes prominent, entire; antenna? not extending to the middle of the elytra, the terminal joints widened, black, the lower four joints more or less fulvous; thorax subcylindrical, but slightly constricted near the base, with a very feeble transverse groove near the same place, preceded at the middle by a short longitudinal depression, impunctate, with the exception of some extremely minute punctures at the middle of tlxe disc ; scutellum black ; elytra testaceous, with deep punctures placed in closely approached rows, the interstices near the apex costate ; legs flavous, the breast, abdomen, and the tarsi black. Hah. Salisbury, Mashonaland, on root of grass (G. Marshall). This little species is of the same Saljringus-Wke shape as L. brevi-cornis Jac, but differs in the colour of the antenna? and in the black underside ; the thorax above also is of more convex shape than in the allied species and the head is black. LEMA NIGROFRONTALIS, sp. n. Elongate and narrow, testaceous, the antenna? and a spot on tlxe top of the head fuscous, the latter pubescent; thorax with a fovea at the sides, impunctate ; elytra closely punctate-striate, tlxe suture and a spot on the shoulder black; tarsi stained with fuscous; breast black, |
