Show 740 MR. M. JACOBY ON THE [Nov. 3, scarcely visibly punctured and granulate. The elytra are very deeply'punctate-striate, and the striae are more closely placed than in the other Japanese species ; the interstices are convex at the sides, and obsoletely transversely wrinkled ; the legs are entirely piceous. P. difficilis, Baly, which has also convex elytral interstices, is much larger, and of a'bright metallic blue, the thorax is distinctly punctured, and the elytral stria? are more finely impressed and more distantly placed. PSYLLIODES JAPONICA, Sp. nOV. Oblong, black below ; antenna?, the anterior legs, and the posterior tibia? flavous ; above dark metallic green ; vertex impunctate; thorax closely punctured ; elytra strongly punctate-striate, the interstices finely punctured. Length 1 line. Head extremely finely granulate, impunctate, with a narrow but deep oblique groove at each side above the antennae, the space between the latter broad and slightly raised. Antenna? entirely flavous, the second joint slightly longer than the third. Thorax twice as broad as long, the sides nearly straight, surface extremely finely granulate, closely and finely punctured. Elytra narrowed at the apices, strongly and regularly punctate-striate, the interstices with a single row of fine punctures, somewhat raised near the apex. Sapporo. Rather smaller than P. augusticollis, Baly ; the head and thorax differently punctured and granulate, and the elytra more strongly punctate-striate, with the interstices not impunctate as in that species, but with a single row of punctures; another different structural character is the oblique groove at each side above the antennae. Genus ENNEAMERA, Har. ENNEAMERA TIBIALIS, sp. nov. Black ; antenna? fuscous ; elytra dark greenish blue, closely punctured ; four anterior legs, base of the posterior femora, abdomen, and the tibiae and tarsi fulvous or testaceous. Length l|-lf line. Head with a few very fine punctures, the frontal tubercles limited behind by a deep transverse groove. Labrum piceous. Antennas obscure fuscous or fulvous, the third joint distinctly longer than the second. Thorax more than twice as broad as long, black, extremely finely punctured, the anterior angles obscure fulvous. Scutellum black. Elytra convex, scarcely widened below the middle, their surface very finely and closely punctured. Jensai, Fukushima, Nikko, Nara. Easily distinguished from E. cyanea, Baly, and E. fulviventris, lialy- bj the black, not blue, thorax, and the colour of'the anterior kgand all the tibiee, as well as by the obscure fulvous antennae. JNine specimens were obtained. |
