The present descriptions are drawn from a small collection which I have lately received from Mr. Sikora, who makes the study of this large island his aim. All the types are contained in m y collection. LEMA RUGICOLLIS, n. sp. Subcylindrical, entirely dark piceous; antennae short and robust; thorax subcylindrical, coarsely punctured anteriorly ; elytra very closely and strongly punctate-striate, the interstices costate at the apex, the ninth row of punctures entire. Length 2 lines. Of parallel, subcylindrical shape ; nearly black, the head not constricted behind, the vertex very finely punctured; eyes moderately deeply notched, subocularigrooves not very deeply marked ; clypeus and labrum obscure fulvous ; antennae scarcely extending beyond the base of the thorax, black, the terminal joints gradually and strongly widened and thickened ; thorax longer than broad, sub-cylindrical, widened at the middle, without a basal sulcation, the surface coarsely punctured anteriorly, finely and closely towards the base, the middle of the disc with a longitudinal depression extending to the base, where it ends in a fovea; elytra with closely-approached rows of deep punctures, the latter also closely placed, the interstices at the sides and apex longitudinally costate ; underside very sparingly clothed with greyish pubescence ; posterior femora not extending to the end of the abdomen. The shape and structure of the thorax, the sculpturing, and the uniform dark colour of this species will distinguish it from any of its allies from the same locality. LEMA MADAGASCARIENSIS, n. sp. Obscure piceous, the base of the head obscure fulvous; antennae very short; thorax nearly impunctate, trifoveolate; elytra with basal depression, strongly and rather distantly punctate-striate, the interstices smooth, costate at the apex. Length 2 lines. Head elongate, finely rugose and pubescent, the vertex fulvous with a central longitudinal groove, the supraorbital grooves rather indistinct; clypeus with a transverse row of punctures ; palpi fulvous; antennae very short, extending only to the base of the thorax; thorax subquadrate, rather broader than long, the anterior angles distinctly tuberculate, the disc extremely closely and finely punctured, the basal sulcus deep, the space behind it with a transverse ridge, the anterior portion with a very short transverse groove at the sides, the middle of the disc with two short elongate foveae, and another at the centre of the sulcus ; scutellum truncate at the apex; elytra with a short depression below the base near the suture, brownish aeneous, deeply and strongly punctate-striate, the punctures rather distantly placed, the 9th row entire ; the interstices smooth, costate at the apex ; underside very dark fulvo-piceous, thinly pubescent, legs more distinctly dark fulvous. |
