Show 1885.] COLEOPTERA FROM JAPAN. 205 Genus NODOSTOMA, Motsch. NODOSTOMA JAPONICUM, Sp. nOV. Black ; head and four basal joints of the antennae fulvous ; head and thorax closely and strongly punctured; elytra with the base swollen, distinctly punctate-striate. Length 2 lines. Head entirely fulvous, closely and very strongly punctured, the middle impressed with a short longitudinal groove ; epistome broader than long, separated from the face by an irregular transverse groove. Terminal joints of the antennae slightly and gradually thickened, the four lower j oints fulvous, the rest black; second and third j oints of nearly equal length. Thorax about twice as broad as long, the sides angulate immediately below the middle ; surface closely covered with deep and round punctures, which at the middle of the disk are now and then confluent. Scutellum impunctate. Elytra with the base strongly swollen, deeply depressed below the latter and within the humeral callus, from which a short costa runs obliquely towards the lateral margin ; the punctuation is strong within the basilar depression, more finely impressed and very regular at the rest of the surface ; the suture is accompanied by two rows of punctures, the latter near the other portion of the apex is very fine. Femora with a small tooth, the knees sometimes as well as the base of the tibiae dark fulvous. Kisa. I cannot find amongst the many eastern forms contained in this genus a species of similar coloration, which is the same in the two specimens I have for examination. All the femora are armed with a small tooth, and the thorax is angulate directly below the middle and not close to the base, as is the case in many other species of Nodostoma. The claws are appendiculate as usual. The two specimens before m e are evidently females. NODOSTOMA RUFICOLLE, sp. nov. (Plate XI. fig. 10.) Underside, legs, terminal joints of the antennae, and elytra black; head and thorax rufous, strongly punctured ; elytra with the base swollen, punctate-striate. Length 2 lines. Head strongly rugose-punctate, the epistome separated from the front only by some smooth raised longitudinal spaces. The four basal joints of the antennae fulvous, the rest black, fourth joint slightly longer than the third. Thorax narrowly transverse, the sides obsoletely angulate near the base, its surface rather convex, rufous like the head, remotely and strongly punctured. Elytra with a distinct depression within the shoulder and below the base, the latter strongly raised and with but few punctures, the latter more crowded and deeply impressed within the depression; rest of the surface more finely and remotely punctate-striate. Intermediate and posterior femora with a minute tooth. Nikko, Fukushima. The dozen specimens obtained at the above locality do not seem |
