Show 92 MR. M. JACOBY ON THE [Feb. I, broad as long, the sides rounded and narrowly margined. Elytra widened towards the middle, very closely and finely punctured ; the prosternum narrow but distinct. Bogawantalawa. S. ceylonensis entirely resembles in regard to colour the unicolorous variety of S. suturalis, but differs in being of much larger size and in having the sides of the thorax much more rounded ; the antennae have their joints also much more elongate, and the punctuation of the elytra is finer and more closely placed. As the four specimens before me all agree in the above characters, I must consider the species specifically distinct from the preceding. S.pallida, Jac, from Celebes, is another very closely allied species, but differs in the depressions of the thorax, the fulvous labrum, and the shorter antennae. SPH^ERODERMA ORIENTALIS, sp. nov. Piceous ; the three basal joints of the antennse fulvous; above reddish fulvous ; thorax very finely punctured ; elytra closely and finely semipunctate-striate. Length 1 line. Head impunctate; the frontal tubercles distinct; lower part of the face prominent, the anterior edge of the clypeus straight. Antennse about half the length of the body, black, the three lower joints fulvous, the second thinner and rather smaller than the preceding, the terminal joints gradually thickened. Thorax transverse, three times broader than long, the sides straight, the posterior margin distinctly sinuate at each side, the median lobe slightly produced and rounded, the surface finely and evenly punctured. Scutellum small. Elytra very convex and distinctly narrowed towards the apices, the shoulders not prominent, the surface very closely and somewhat more distinctly punctured than the thorax, the punctuation arranged in semiregular rows. Legs piceous. Prosternum longer than broad. Elytral epipleurae broad, nearly extending to the apices. Galle. I am unable to say whether the present species is identical with one or the other described by Motschulsky. In some specimens the thorax is more or less stained with piceous. CHABRIA (gen. nov. Halticinorum). Anterior coxal cavities open. Body ovate, rounded, very convex. Antennae widely separated, filiform, slightly thickened towards the apical joints. Thorax narrowly transverse, four times as broad as long, the sides rounded. Scutellum triangular. Elytra irregularly punctured, convex, strongly deflected towards the apices, their epipleurae broad and continued below the middle. Posterior femora strongly incrassate; tibiae not channelled, the posterior ones with a distinct spine ; the first joint of the posterior tarsi as long as the two following joints together; claws appendiculate.
