Show 1878.] MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. 985 well as to L. cyaneum, Lac, it is from both distinguished by its smooth prosternum, from the former by the punctured head, from the latter by the want of the depression at the head. 5. NODA LEFEVREI, sp. nov. Broadly ovate, uniformly greenish a?neous. Head coarsely, thorax less strongly punctured. Elytra semipunctate-striate, costate near the apex. Length 1| line. Head strongly and closely punctate, especially between the eyes, where the punctures are of an oblong shape. Eyes very prominent; clypeus also strongly punctured, separated from the face, its anterior margin crescent-shaped ; antennae as long as half the body, the last five joints much thickened, and the terminal one very robust and strongly pointed at the apex, the lower six joints shining greenish a?neous above, fulvous below, the rest black and opaque. Thorax very narrowed towards the apex, with the posterior angles acutely produced ; surface moderately punctured, the punctures not stronger near the sides than those on the disk, and not extending to the anterior or the posterior margin. Scutellum with a few punctures. Elytra convex, with a very obsolete depression below the base; surface very deeply and regularly punctate-striate near the outer margin, finer and more irregularly towards the suture ; the intervals towards the apex raised in longitudinal costa?, of which the third and fourth (counting from the outer margin) are united posteriorly sending off a short costa towards the apex. Underside and legs a?neous, extreme apex of the tibia? and the tarsi darkish rufous. Hab. Costa Rica (volcano of Irazu) ; Guatemala. Closely allied to Noda semicostata, Lefevre ; but distinguished by the equal punctuation of the thorax, which, in the former species, is, according to the description, strong and dense at the sides. 6. NODA BALYI, sp. nov. Broadly ovate, a?neous, shining ; antenna?, palpi, and legs ferruginous. Elytra punctate-striate, with a short round tubercle on the disk of each elytron. Length 1| line. Head rather deeply but widely punctured, the clypeus not separated from the face ; antenna? with the third, fourth, and fifth joints of equal length, entirely ferruginous. Thorax of the same shape as in N. viridis, distinctly punctate throughout, greenish bronze-coloured. Elytra convex, a little more strongly punctured than the thorax, the punctures arranged in regular stria?, the intervals scarcely raised except near the lateral margin and the apex, where they are semicos-tate ; the humeral callus prominent; and each elytron is furnished at a little distance before the middle with a short round tubercle, which is placed nearer the lateral margin than the suture ; a very shallow transverse depression is also visible in certain lights immediately above this tubercle. Underside greenish black, opaque ; legs ferruginous. Hab. Guatemala. |
