Show 734 MR. M. JACOBY ON THE [Nov. 3, of the posterior tibia? as long as the two following joints together, claw-joint distinctly swollen. Yuyama, Hitoyoshi. There are three specimens of an entirely fulvous colour, and three in which the thorax only is of this shade. The species is closely allied to H beavani, Baly, from India; but in the latter the elytra are of a metallic blue or green colour, and the head shows no traces of strigae. Genus A R G O P U S , Fisher. A R G O P U S NIGRIPENNIS, sp. nov. Black; lower part of head fulvous; thorax narrowed in front, closely punctured ; elytra irregularly and closely punctate. Length 2 lines. Head impunctate at the vertex ; frontal tubercles divided and hounded behind by a moderately deep transverse groove; lower part of face rugosely punctured, fulvous. Antennae more than half the length of the body, black, the apices of the first three joints fulvous, second and third joints equal, one half shorter than the fourth. Thorax narrowed in front, the sides but little rounded, surface rather closely and irregularly punctured, the basal margin impressed at each side with a row of deeper punctures. Scutellum fulvous. Elytra not more strongly punctured than the thorax, the punctuation irregular and only here and there arranged in striae, the punctuation absent at the anterior portion near the lateral margin, the latter impressed with a deep row of punctures. Underside and legs black, the anterior coxa? and the apex of the abdomen fulvous. Shimonosuwa. I am somewhat doubtful whether the single specimen before me represents really a new or a variety of one or other species of Argopus, perhaps A. nigritarsis. The thorax of that species is, however, more transverse and less narrowed in front, and the general shape of the insect more rounded ; the black colour of the present species is unique amongst its allies. ARGOPUS CLARKI, sp. nov. Ovate, convex, pale fulvous; antenna? (the three basal joints excepted) and legs black ; thorax very finely punctured; elytra strongly subgeminate punctate-striate. Length 2 lines. Head impunctate, the frontal tubercles flattened and broad. Antennae half the length of the body, black ; the three basal joints fulvous, second and third joints short and equal. Thorax at least three times as broad as long, the sides rather rounded, the anterior angles oblique; surface rather closely covered with fine and larger punctures, a row of the latter accompanying the posterior margin. Elytra strongly punctate-striate, the punctures arranged in irregular and rather remotely placed double lines, the space near the lateral margins impunctate. Underside fulvous. Legs black. Miyanoshita. |
