Show 102 MR. M. JACOBY ON THE [Feb. 1, nearly square-shaped and smooth ; labrum piceous. Antennae nearly as long as the body, testaceous, the third and following joints elongate, nearly equal in length and much longer than the second joint. Thorax more than twice as broad as long, the sides rounded at the middle, narrowed near the anterior angles, the latter slightly prominent ; the surface shining, scarcely visibly punctured near the side, with a short anterior and posterior transverse groove and a small anterior fovea as well as an obsolete oblique posterior lateral depression. Scutellum obscure fulvous. Elytra closely pubescent, very finely rugose-punctate, the basal margin and the sides to below the middle obscure piceous or fuscous, the rest of the surface very obscure fulvous. Legs and underside testaceous ; the claws indistinctly bifid. SPH_EROPLEURA (gen. nov. Halticinorum). Body strongly rounded and convex. Antennae filiform, the first joint slender, the second and following joints nearly equal and shorter. Thorax subhemispherical, without depression. Elytra punctate-striate, their epipleurae very broad and concave, continued to below tbe middle ; the posterior femora strongly dilated ; the four posterior tibise mucronate ; the first joint of the posterior tarsi as long as the two following joints united; claws appendiculate. Prosternum narrow, deeply longitudinally channelled. Mesosternum deeply emarginate at its apex. Anterior coxal cavities closed. Spharopleura agrees in shape, which resembles that of a species of Coccinella, with Spharophyma, Baly, Argopistes, Motsch., and Homelea, Jac It differs from the first-named genus in the much less strongly dilated posterior femora, the longer and not dilated tibiae, and the smaller eyes, also in the want of a thoracic median lobe. From Argopistes this genus may be separated by the filiform antennae and the punctate-striate elytra; and from Homelea by the much more strongly incrassate posterior femora, the latter in Homelea being only about one half thicker than the rest of the thighs, and the mesosternum strongly transverse and of different shape, and the elytra irregularly punctured. SPHAROPLEURA TRICOSTATA, sp. nov. Piceous below ; antennse, tibiae, and tarsi testaceous; head and thorax impunctate, black; elytra finely punctate-striate. 2 . Each elytron with three short but distinct costae near the apex. Var. Elytra fulvous. Length 1| line. Head entirely impunctate ; the frontal tubercles very small and indistinct; labrum fulvous. Antennae about half the length of the body, testaceous, the terminal joint fuscous. Thorax subhemispherical, more than three times as broad as long, the sides straight, the angles not produced but distinct. Elytra wider at the base than the thorax, very convex and rounded, the punctuation very fine at the middle of the disk, much more distinct towards the sides ; of the three costae placed near the apex in the female, the first is shorter |
