Show 1902.] OF AMERICAN COLEOPTERA. 201 OXYGONA NIGRICOLLIS, Sp. n. Black, head and thorax impunctate ; elytra pale flavous, nearly impunctate. Length 5-6 millim. Head entirely impunctate, with an oblique depression above the eyes, the frontal tubercles strongly raised, the carina short and broad; antennae black, extending beyond the middle of the elytra, the third and the following two joints very elongate, the others shorter; thorax more than twice as broad as long, the sides subangulately rounded before the middle, strongly narrowed at the base, with a broad reflexed margin, the anterior margin accompanied by a narrow sulcus, the disc entirely impunctate, shining, black; scutellum black; elytra pale flavous, extremely minutely punctured ; below and the legs black. Hab. Espirito Santo, Brazil. This typical Oxygona, of which three specimens are before me, is well distinguished by its system of coloration. CREPIDODERA FLAVOMACULATA, sp. n. Piceous, above black, the basal joints of the antennae and the legs (the posterior femora excepted) testaceous ; thorax opaque, minutely punctured and granulate, feebly transversely sulcate ; elytra very closely punctate-striate, piceous, the humeral callus and the apex flavous. Length 2 | millim. Head entirely impunctate, black, the frontal elevations obsolete, clypeus convex between the antennae, labrum flavous; antennae extending beyond the middle of the elytra, testaceous, the terminal joints more or less darkened, second and third joints of equal length, shorter than the fourth, terminal joints thickened ; thorax subquadrate, one-half broader than long, the sides nearly straight, the angles distinct, the surface opaque, finely punctured and minutely granulate, the basal sulcus feeble, not extending to the sides, the space below it also distinctly punctured; scutellum black, impunctate; elytra wider at the base than the thorax, extremely closely punctured in irregular rows, the apex much more finely punctate, the disc blackish, the shoulders with a small flavous spot, the apex more or less broadly of the latter colour, the space along the suture somewhat depressed; below piceous, the legs testaceous or flavous, the posterior femora piceous, their metatarsus as long as the two following joints together, all the tibiae with a small spine, prosternum very narrow; the anterior coxal cavities closed. Hab. Concepcion, Talcahuano, Chili. The thorax in this species is of an opaque, silky appearance and the sulcus but feebly impressed, although distinct. I cannot refer this insect to any of the species described by Philippi from the same country. PROC. ZOOL. Soc-1902, VOL. I. No. XIV. 14 |
