Show 576 MR. M. JACOBY ON NEW [Nov. 1, following joints together ; claws appendiculate ; the prosternum very narrow, convex between the coxae ; the anterior coxal cavities open. MALACOSOMA FLAVICORNE, n. sp. (Plate XXXIX. fig. 12.) Flavous; the clypeus, thorax, the apex of the femora, and the abdomen black ; thorax closely punctured; elytra flavous, punctured like the thorax. Length 2;| lines. Head impunctate, pale fulvous, the frontal elevations narrowly transverse; the clypeus black ; antennae fulvous, rather robust, the third joint one half longer than the second, the fourth as long as the preceding two joints together ; thorax about twice as broad as long, the sides rounded, the anterior angles slightly produced, the posterior ones rather obsolete, the surface rather strongly and closely punctured, black; elytra flavous, very closely punctured; the apex of all the femora black ; tibiae mucionate, the first joint of the posterior tarsi as long as the following two joints together; claws appendiculate ; abdomen black, pubescent; prosternum very narrow but distinct, convex. A single specimen. ANTSIANAKA VIRIDIS, n. sp. Testaceous; the antennae, the abdomen, and the tibiae and tarsi black ; the head and thorax impunctate ; elytra metallic green, finely punctured and transversely rugose. Length 2 lines. Head with a more or less distinct depression at the vertex, the latter with a faint metallic hue, impunctate ; labrum black ; antennae as long as the body, very slender, black, all the joints with the exception of the second very elongate; thorax short, without a distinct lateral margin, the surface impunctate, with some shallow transverse depressions, testaceous ; scutellum black ; elytra bright metallic green, finely transversely rugose, and closely punctured. Closely allied to A. pulchella, Duviv., but differing in the pale head, the absence of the green thoracic margin, the entirely green elytra, and the black abdomen. ANTSIANAKA LONGICORNIS, Duviv. I refer a single specimen to this species ; m y specimen differs, however, from the description in having an entirely testaceous head. M . Duvivier does not mention the colour of the antennae, which are fuscous in my specimen with the basal two joints black. ANTSIANAKA ELEGANTULA, n. sp. (Plate XXXIX. fig. 10.) Pale flavous ; antennae (the basal two joints excepted) black ; elytra metallic blue, narrowly margined with flavous, rather strongly punctured ; the interstices finely transversely rugose. Length 1^ line. Smaller than any of its allies, the antennae extending beyond the elvtra, entirely black, with the exception of the first two joints, which are flavous ; the head swollen, impunctate ; the thorax very |
