Show 986 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [DeC. 3, Collected by Mr. Salvin. Collection Jacoby. Allied to N. propinqua, Lefevre, but differing in the stronger punctuation of the thorax and the sculpture of the elytra. 7. NODA VIRIDIS, sp. nov. Broadly ovate, shining metallic-green above, below greenish black, the first six or seven joints of the antenna? and the legs entirely ferruginous. Length l^-lij line. Head coarsely but widely punctate, the clypeus distinctly separated, also strongly punctured, with the anterior margin emarginate ; labrum dark ferruginous or brown; vertex of head with an obsolete longitudinal groove. Antennse of half the length of the body, very robust, with the exception of the short second joint, gradually-thickened towards the apex, the three penultimate joints of nearly equal length and cylindrical, the terminal joint the longest of any, and pointed at the apex ; the first six or seven joints ferruginous, the rest black, opaque. Thorax transverse, the anterior margin nearly straight, the posterior one evenly rounded and produced in the middle, the sides nearly parallel at the base, but narrowed towards the apex, all the angles acute ; surface shining metallic green with a slight bluish tint, not very closely but rather deeply punctate- Scutellum smooth. Elytra slightly wider at the base than the thorax, very gradually and evenly rounded towards the apex ; disk rather convex, without any basal depression ; the humeral callus produced and smooth ; surface finely punctured a little more strongly near the base, the punctures arranged in rather regular lines, partially running in pairs, and forming one stria near the suture towards the apex. Underside opaque blackish green. Legs and tarsi ferruginous. Hab. Guatemala. Collected by Mr. O. Salvin. In m y collection. 8. NODA BOUCARDI, sp. nov. Broadly ovate, above violaceous blue, shining, below greenish black. Tibia?, tarsi, and base of the antennse rufous. Elytra geminate-punctate-striate. Length 1| line. Head strongly punctured, especially towards the lower part, shining greenish blue ; antenna? with the first six joints light rufous, the rest darker. Thorax of the same shape as N. lefevrei of this paper, also equally punctate throughout, the puncturing extending at the same time to all the margins. Elytra not differing in form from the above species, the punctuation on the disk, however, united in pairs, and only the extreme apex distinctly costate. Underside semiopaque, greenish black, all the tibia? and tarsi bright rufous. Hab. Valin, Guatemala. Collected by Mr. Salvin. Allied to Noda rufipes, Lefev. (Mittheil. Munch. Ent. v. 1878), but differing in the equal punctuation of the thorax, the double rows of punctures of the elytra, and the costate apex of the latter. |
