Show 728 MR. M. JACOBY ON THE [Nov. 3, LONGITARSUS HEMORRHOIDALS, Sp. UOV. Ovate, convex, black ; legs (the apices of the posterior femora excepted) pale fulvous ; thorax very finely punctured ; elytra blacK, the apices fulvous, distinctly semipunctate-striate. Length 1 line. . , Head impunctate; eyes large ; the frontal tubercles entirely absent. Antenna? nearly as long as the body, black, the three or four basal joints fulvous, third and fourth joints equal in length, slightly longer than the second. Thorax transversely subquadrate, the sides nearly straight, not converging, the anterior angles obliquely thickened ; surface very minutely and not very closely punctured, the interspaces extremely finely granulate when seen under a strong lens. Elytra narrowed at the apices, slightly widened at the middle in the female, their surface much more strongly punctured than that of the thorax, and arranged in close and rather regular rows, black, the apex more or less broadly fulvous. Metatarsus of the posterior tibia? half their length, the apex of the posterior femora more or less piceous, the rest and the other legs fulvous. Yokohama. Smaller and less robust than the European L. apicalis, the antenna? shorter and not so thick, the thorax more finely punctured and less transverse, and the punctuation of the elytra more regularly arranged. LONGITARSUS ORIENTALIS, Sp. nOV. Ovate, narrow behind, pale testaceous ; antennae, their basal joints excepted, the sutural margin of the elytra, and the posterior femora piceous ; thorax extremely finely, elytra more distinctly punctured. Length 1^-11 line. Head extremely finely transversely wrinkled when seen under a strong lens, with a rather deep impression near the inner margin of the eyes ; the frontal tubercles indistinct; carina strongly raised. Antennae nearly as long as the body, piceous or black, the three or four basal joints obscure testaceous, third joint longer than the second, but distinctly shorter than the fourth. Thorax transverse, rather more than twice as broad as long, the sides straight, not converging, the anterior angles oblique, surface very finely punctured when seen under a strong lens, rather convex. Elytra widened towards the middle, narrowed at the apex, closely and a little more distinctly punctured than the thorax, the interstices not wrinkled, the suture narrowly piceous through its entire length, but this colour slightly widened below the middle; posterior femora and the last joints of the tarsi piceous. Kuiigahara. Nine specimens of this species were obtained : it is no doubt allied to several European forms and to one or two others described by Motschulsky, the descriptions given by this author being too superficial to identify with certainty his species. L. orientalis may be known by its comparative large size, the trans- |
