Palpi robust, the penultimate joint strongly incrassate. Antennae half the length of the body, the third joint longer than the second, but shorter than the fourth. Thorax subquadrate, broader than long, the sides straight at the base, and narrowed, converging to the apex ; surface with two deep depressions, black, shining, impunctate. Elytra broader than the thorax, the shoulders prominent and bounded within by a rather deep longitudinal depression, the base distinctly raised, the disk very minutely punctured ; a narrow longitudinal ridge, abbreviated near the apex, is situated at the middle of the disk ; another extends from the shoulder nearly to the apex. Underside and legs black, the latter slender ; tibia? unarmed, the first joint of the posterior tarsi as long as the two following joints united ; claws appendiculate. Abdomen testaceous ; anterior coxal cavities open ; elytral epipleura? extremely narrow. Osaka. Genus L U P E R U S , Geoffr. L U P E R U S HIRSUTUS, sp. nov. (Plate XLVI. fig. 4.) Entirely black, covered with very fine yellowish pubescence; antennae longer than the body in the male ; thorax finely rugose ; elytra minutely punctured. Length 2 lines. Head very finely rugose-punctate, the frontal tubercles rather distinctly raised. Antennae about one half longer than the body in the male, shorter in the female, black ; the underside of the first three joints sometimes testaceous, fourth joint slightly longer than the third. Thorax subquadrate, one half broader than long, the anterior angles slightly thickened and produced in a short shining black tooth ; the surface rather depressed, finely rugose-punctate and covered with very short pubescence. Elytra a little widened towards the apices, pubescent like the thorax, the punctuation extremely close and fine. The metatarsus of the posterior legs longer than the following joints together. Nikko, Yuyama, Kiga, Hitoyoshi. The short silky pubescence of this species, which covers the entire upper surface, but allows the punctuation to be well seen, will distinguish the insect at first sight.
