Show 220 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, has its base truncate, not rounded, and the posterior angles are but little produced; in one specimen the thorax is without any markings and the entire underside is flavous, the elytra have also the dark spots less strongly marked. EUMOLPINiE. MICROHEBMESIA, gen. nov. (group Colaspince). Oblong ; antennae filiform, eyes entire ; thorax transverse, the sides angulate and with a narrow margin; elytra semi-regularly punctured; legs robust, the anterior femora with a minute tooth, tibiae not sulcate, the metatarsus of the posterior legs as long as the following two joints together, claws appendicular^; prosternum broad, scarcely narrowed between the coxae, its base truncate ; the anterior margin of the thoracic episternum concave. In its general appearance, the little species for which I propose this new genus resembles Lefevrea, but differs in the angulate sides of the thorax, which places it amongst the group Colaspince, which up till now had no African representative ; the much broader prosternum and the minutely dentate anterior femora separate the genus from Colaspis proper ; the shape of the thorax agrees better with Hermesia, but that genus differs in other details, notably the unarmed femora, although this latter character must be used with caution and only in conjunction with others as a generic distinction. MICROHERMESIA HIRTICOLLIS, sp. n. (Plate XX. fig. 7.) d. Below black, base of the antennae and the legs fulvous ; thorax aeneous, closely punctured and finely pubescent ; elytra strongly punctured anteriorly, flavous, the middle with a transverse broad cupreous or aeneous patch. 2 (?)• Above entirely flavous, with a slight metallic gloss. Length 2\ millim. Head aeneous or cupreous, closely punctured and sparingly clothed with short pubescence ; the clypeus not separated from the face, transverse; antennae slender, extending to about the middle of the el\tra, flavous, the terminal joints slightly stained with fuscous, basal joint much thickened, second and third equal in length, fourth and following joints slightly longer and very feebly thickened towards the apex; thorax twice as broad as long, the sides with a narrow margin and distinctly angulate at the middle, the anterior angles distinctly tuberculate, the tubercle produced and provided with a single seta, the anterior and posterior margins straight, the surface punctured and pubescent like the head; scutellum broader than long, its sides rounded; elytra broader at the base than the thorax, the shoulders angulate, the base with a feeble transverse depression, Ihe surface rather strongly punctured in closely arranged irregular rows, with some more minute punctures at the interstices, flavous, with a slight metallic gloss the middle of the disc with an irregular, rather ill-defined transverse |
