Show 732 MR. M. JACOBY ON THE [N surface closely and finely punctured, the interstices somowhat wrinkled. Elytra strongly and regularly punctate-striate, the interstices impunctate and slightly convex, costate at the sides and apex. Legs fulvous, the tibia? with a darker more or less distinct mark, the posterior femora dark aeneous. Hosokute. C. chalceola is evidently closely allied to C. granulifrons, Baly, of which I have the type for comparison, but in that species the thorax is more finely punctured as well as the elytra ; the antenna? are nearly entirely fulvous as well as the tibia?, and the shape of the insect is rather narrower and less robust. It may be, however, that the present insect is but a local form of Baly's species. CHETOCNEMA JAPONICA, sp. nov. Ovate, convex, aeneous ; antenna? and legs fulvous ; head rugose-punctate ;. thorax closely and strongly punctured ; elytra deeply punctate-striate, the interstices minutely punctured. Length 11 line. Head extremely finely granulate, strongly and very closely punctured throughout, the punctures sometimes confluent. Antenna? not extending further than the base of the elytra, fulvous, the apices of all the terminal joints stained with fuscous ; the second, third, and fourth joints of nearly equal length. Thorax transverse, slightly widened at the middle, the sides slightly rounded ; surface closely covered with round punctures, which are more strongly impressed at the sides than at the disk, the latter with a more or less distinct central, smooth, longitudinal space. Elytra a little widened towards the middle, very strongly and regularly punctate-striate; the interstices minutely punctured when seen under a strong lens, costate at the sides. Legs pale fulvous, the posterior femora stained with greenish a?neous. Hakodate, the sandhills, Fukushima, Niigata. Closely allied to C. ingenua, Baly, from China, hut more robust and of larger size, the head more strongly and closely punctured, and the elytral interstices minutely punctate ; in C. ingenua the latter are impunctate. CHETOCNEMA FULVIPES, sp. nov. Dark aeneous ; antennae, anterior legs, and posterior tibiae fulvous ; head and thorax closely punctured ; elytra deeply punctate-striate, the interstices sparingly punctured. Length l£ line. Head closely rugose-punctate, the frontal tubercles and the carina entirely absent, lower part of face covered with some yellowish pubescence ; palpi fulvous ; antenna? of the same colour, scarcely half the length of the body, the second joint as thick as, but one half shorter than, the first, the following three as long as, but much thinner than, the second joint, the terminal five short and of equal length. Thorax nearly three times as broad as long, the sides very slightly rounded, surface finely but very closely punctured, the punctures |
