Show 744 MR. M. JACOBY ON THE [N interstices transversely wrinkled and sparingly covered with short yellowish hairs. Legs testaceous, the tarsi somewhat darker. Principally distinguished by the three-spotted thorax, in connection with the narrow black sutural and lateral margins of the elytra, which colour separates the species from G. nymphaa, L., to which it seems closely allied ; but. in the latter the margins of the elytra are paler than the disk, and show no trace of darker colour. GALERUCELLA SEMINIGRA, sp. nov. Elongate, parallel, subcylindrical; black; elytra fulvous, pubescent; head and thorax very finely punctured, the posterior margin of the latter obscure fulvous ; elytra extremely finely and closely punctured. Length 3\ lines. Head broadly depressed at the middle, finely and closely rugose-punctate, labrum margined with testaceous. Antennae half the length of the body, the second and third joints of equal length, and shorter than the other joints, their apices more or less testaceous. Thorax more than three times as broad as long, the sides slightly rounded at the middle, nearly straight at the base, the posterior angles oblique ; the surface with three deep longitudinal depressions, the central one of a more triangular shape ; middle of the disk very finely, the sides more strongly punctured, rather shining ; black, the posterior margins obscurely edged with fulvous. Scutellum broad, its apex broadly rounded, black, pubescent. Elytra reddish fulvous, extremely closely and finely punctured, and covered with yellowish hairs. Underside and legs black ; the first joint of the posterior tarsi slightly longer than the second. Yagohara. A single specimen. Principally distinguished by the black head and thorax, and the fulvous elytra, in connection with its rather larger size. GALERUCELLA VIRIDIPENNIS, sp. nov. (Plate XLVI. fig. 9.) Elongate, parallel; black ; head and thorax finely rugose-punctate; elytra metallic green, finely rugose and pubescent. Length 2 lines. Head rugosely punctured, the frontal tubercles divided by a deep groove. Antennae black, nearly as long as the body, the third joint double as long as the second, but much shorter than the fourth, the following joints gradually decreasing in length. Thorax twice as broad as long, the sides slightly rounded, the anterior and posterior margin straight; the disk with a transverse deep depression at each side, which is but slightly interrupted at the middle, rather finely and irregularly punctured and sparingly covered with yellowish hairs. Scutellum black. Elytra bright metallic green, very finely and closely rugose, sparingly pubescent. Tibiae unarmed. Claws bifid. Anterior coxal cavities closed. Kurigahara, Wada toge. Of this handsome species a good many specimens were obtained ; the bright green elytra, and black head and thorax will at once assist in its recognition. |
