ON [Feb. 16, has lately pointed out, and rightly so, that most of the species described under Pseudocolaspis belong to Eubrachys Baly, on account of the concave, not convex, anterior margin of the thoracic episternum. The genus therefore requires revision when the types can be compared. ECHTRUSIA CAPENSIS, Sp. IX. Ovate, a?neous, antenna? piceous, apex of the tibia? fulvous ; head and thorax finely punctured, punctures of the latter elongate ; elytra sparingly pubescent, finely punctured. Length 3 millim. Head rather flattened, finely and closely punctured, apex of the epistome triangularly emarginate, the lower joints of the antenna? obscure cupreous, the terminal five joints piceous, strongly thickened; thorax about one-half broader than long, strongly narrowed anteriox-ly, tlxe sides nearly straight, the margins distinct, the disc closely and finely impressed with elongate punctures, which are more crowded at the sides; scutellum tx-ansverse, its apex x-ounded ; elytra ovate, convex, the sides strongly rounded, the lateral margins below the shoulders oblique, the surface finely and closely punctured and sparingly pubescent; femora strongly thickened, unarmed, prosternum very broad, claws bifid. Hab. Dunbrody, Cape Colony (Rev. J. A. O'Neil). 1 have received a single specimen from the Rev. J. A. O'Neil, tlxe sex of which is uncex-tain. It is tlxe second species of the genus established by Lefevre, axxd differs from tlxe type in being smaller, in having differently coloured antenna? and legs, and the thorax impi-essed with elongate punctures ; it is possible that the elytra in the specimen befox-e m e are partly rubbed as regards the pubescence. The broad and rounded scutellum, very broad prosternum and mesosternum, and the stx-ongly narrowed thorax separate tlxe genus from Pallena axxd allied genera. SCELODOXTA RUGIPENNIS, Sp. IX. Dark cupreous, the apical joints of the antenna? black ; thorax finely transversely wrinkled ; elytra confluently rugose-punctate, the interstices finely costate at the apex with single white hairs, sides of the breast densely pubescent. Length 4 millim. Head strongly rugose, the vertex with a central groove, supraocular sulci very deep ; antenna? with the lower joints cupreous, the last five black, strongly widened ; thorax scarcely wider than long, the sides widened at the middle, the whole surface finely transversely wrinkled; elytra transversely depressed below the base, narrowed at the apex, closely confluently punctured throughout, the punctures stronger at the base than posteriorly, the interstices at the apex with a few short costa? and sparingly provided with single whitish hairs; parapleura? of the breast clothed ^\ it.Ix dense white pubescence |
