Show 84 MR. M. JACOBY O N T H E [Feb. 1, different shape of its groove, and the general colour seem to an allied but different genus. ENNEAMERA CEYLONENSIS, sp. nov. Testaceous ; a spot at the vertex and the scutellum black ; head and thorax impunctate ; elytra scarcely visibly punctured, testaceous, a triangular-shaped spot at the base and a narrow transverse band below the middle reddish fulvous. Var. Elytra entirely dark fulvous. Length 2 lines. Head broader than long, impunctate, a large spot at the vertex black ; frontal tubercles obsolete ; labrum piceous. Antennae entirely pale fulvous, the second and third joints short, the rest transversely dilated. Thorax three times as broad as long, widened at the middle, the sides nearly straight, narrowed in front, the anterior angles slightly thickened and distinct; the surface entirely impunctate, pale testaceous. Scutellum black. Elytra microscopically finely punctured, very convex and rounded, of a yellowish colour, a transverse triangular-shaped band at the base, not quite extending to the sides, and marked with a more or less distinct black spot at the shoulder, reddish fulvous ; the narrow band behind the middle of a more piceous colour; the outer margin of the posterior tibise with a row of small black teeth or spines. Besides the above-named fulvous variety, which does not vary in other respects from the typical form, I possess a specimen in my collection (also from Ceylon) in which the posterior band of the elytra is divided into two small spots. PHYLLOTRETA DISCOIDEA, sp. nov. Head, thorax, and the abdomen fulvous ; antennae, the breast, and legs black; elytra scarcely visibly punctured, testaceous, all the margins narrowly black. Length 1| line. Head impunctate, fulvous, the frontal tubercles transverse, narrow and very distinct. Antennae half the length of the body, black, the third joint smaller than the second, the following ones gradually thickened. Thorax transversely quadrate, the sides slightly rounded; the surface rather flat, with a very obsolete and shallow depression at the middle of the sides, entirely impunctate. Scutellum black. Elytra parallel, not covering the pygidium, their surface only visibly punctured when seen under a strong lens, testaceous or yellowish, margined with black, the sutural margin generally narrowed near the base. Breast and legs black, the anterior femora slightly stained with fulvous below; the abdomen, with the exception of the last segment which is black, fulvous. Bogawantalawa. P. discoidea may be recognized by the small third joint of the antennse, which is smaller than the second (au exceptional structure as a rule), and by its general coloration. |
