Show 444 MR, MARTIN JACOBY ON NEW SPECIES [Nov. 28, by Clark, and formerly in the Baly collection. The colour of the elytral bands, their shape, and the more than usually convex anc widened general shape of the insect, distinguish this species. Whether 0. jaculus Illig. is identical with this or some other similarly marked species I am unable to say, but Illigei s description of the shape of the elytral bands does not agree with that of the insect before me. O ed io n y ch is r e g in a , sp. n. (Plate XIY. fig. 12.) Large and broad, black, the last two joints of the antennae pale yellow ; thorax impunctate, flavous, with a large black transverse band; elytra strongly and very closely punctured, metallic dark green; the lateral margins and a transverse band below the middle testaceous. Length 10 millim. Head bluish-black, impunctate, except near the eyes, the latter with a flavous spot near the inner margins, widely separated; antennte slender, black, the last two joints pale flavous, third joint slightly shorter than the fourth ; thorax rather more than twice as broad as long, the sides broadly flattened, evenly rounded, the anterior angles thickened, very slightly produced outwards, the disc impunctate, black, the lateral and basal margins flavous; scutellum black ; elytra widened below the middle, closely and strongly rugose-punctate, metallic green, the lateral margins narrowly and a slightly wider transverse band, immediately below the middle, testaceous; under side and legs black. Hab. Espirito Santo, Brazil. The black thoracic band which extends to the anterior margin, the colour of the antennae, and the strongly punctured elytra well distinguish this species from any other. O e d io n y ch is d if f ic t l is , sp. n. (Clark, MS.). Black, thorax flavous, impunctate ; elytra convex, widened posteriorly, closely and finely punctured, flavous, a broad transverse band at the base and another band below the middle, with the lateral and posterior margins rounded, metallic blue, both bands not extending to the margins. Length 6-9 millim. Head impunctate, black, two or three deep punctures are placed near the eyes, frontal tubercles trigonate, nearly connected ; antennae rather long, black, the base at their insertion flavous, third and fourth joints nearly equal; thorax twice as broad as long, the sides rounded anteriorly, the anterior angles produced into a small tooth, the disc impunctate, flavous or fulvous ; scutellum black; elytra widened towards the middle, convex, finely and closely punctured, flavous, with two transverse dark blue bands-the first at the base, of regular shape, with its posterior edge straight and not quite extending to the middle, the second band below the latter, its anterior margin straight, but the lateral and apical margins rounded, the last-named some |
