Show 572 MR. M. JACOBY O N T H E [May 18, AULAMORPHUS, n. gen. Body ovately subquadrate; antennae subfiliform, the terminal joints thickened, the second and third joints short; thorax transverse, with tbe anterior angles oblique, the disc with two transverse sulci; elytra irregularly punctured, their epipleuras broad and continued below the middle ; legs robust, the tibias unarmed, the first joint of the posterior tarsi as long as the following three joints together; claws appendiculate; prosternum very narrow and rather convex ; the anterior coxal cavities closed. The species for which this genus is proposed has entirely the appearance of those belonging to the genera Galeruclcla and Sphe-norala, inhabiting China and India, and can only be separated by the unarmed tibias, no spines being visible, even under the microscope. The place of the genus will be near Galeruca, from which it differs in the transverse sulci of the thorax and in the unarmed tibias. Two specimens were obtained by M r . C. Hollis in Uzum-bara, German East Africa, and kindly given to me by that gentleman. AULAMORPHUS HOLLISI, n. sp. (Plate XXXIV. fig. 12.) Testaceous, the antennae (the basal joints excepted) and the legs black; head with one, thorax with three black spots, strongly punctured; elytra closely and strongly punctured, a narrow longitudinal stripe at the disc and two spots before and below the middle at the sides, together with the apical margins, black. Length 2f lines. Head with a few fine punctures and a short central groove, testaceous, the vertex with a black spot, frontal tubercles transverse, broad ; clypeus with a central groove, black ; palpi moderately thickened"; antennas extending to about the middle of the elytra, black, the lower three joints testaceous below, the second joint short, the third slightly longer, fourth joint the longest, the following rather thickened and shorter ; thorax nearly three times broader than long, the sides straight, the anterior angles oblique, the posterior margin strongly obliquely shaped at the sides, the disc with an obsolete transverse depression before the middle, and a deeper sulcus at each side, not extending to the middle or the lateral margin, the surface deeply and irregularly punctured, testaceous, with a larger central and a smaller spot at each side; scutellum broad, black ; elytra wider at the base than the thorax, slightly depressed below the former, very strongly and closely punctured, testaceous, tbe suture posteriorly and the apical margins narrowly black, a narrow similarly coloured stripe extends from the middle of the base to below the middle of each elytron, to this is joined a rounded spot below the shoulder and another at the apex of the stripe at the sides : underside testaceous ; legs black ; the abdominal segments also marked with a piceous spot at the sides.
