Elongate, nearly parallel, testaceous; antennae black, the basal joint testaceous, the apical one fulvous ; thorax impunctate, the sides rounded, the anterior angles scarcely mucronate; elytra extremely minutely punctured. Length 5 millim. Head impunctate, the eyes very large, frontal elevations broad, not strongly raised; clypeus deeply deflexed, not prominent; antennae not quite extending to the middle of the elytra, black, the basal joint testaceous, the last one fulvous, third joint shorter than the fourth ; thorax twice as broad as long, of even width, the lateral margins moderately strongly rounded, the anterior angles scarcely produced or mucronate, the sides deeply sulcate, the surface impunctate; scutellum testaceous; elytra slightly widened towards the middle, narrowly margined, extremely minutely and closely punctured; metatarsus short ; claw-joint strongly swollen. Hab. Bolivia. Closely allied to 0. pallescens but larger and the antennae and legs of different coloration. 0. paupera Illig. is described as being only 3 millim. in length and with an elongate first joint of the posterior tarsi, which show that the species is an Asphcera. O e d io n y ch is so r d id a , sp. n. Black, the head strongly punctured; thorax flavous, with rounded sides and mucronate anterior angles, impunctate; elytra finely punctured, flavous, the basal portion obscure fulvous; scutellum black. Length 7| millim. Broadly elongate, nearly parallel; the head bluish black, strongly and closely punctured, deeply transversely depressed between the eyes, the latter widely separated ; antennae rather short, black, the lower three joints shining, the rest pubescent, basal joint short and thick, third and fourth joints subequal, the last of wider shape, the following joints rather robust, cylindrical, slightly shorter ; thorax twice as broad as long, of equal width, the sides deeply sulcate, the lateral margins rounded, the anterior margin produced outwards in shape of a small tooth, the surface flavous, impunctate; scutellum black ; elytra slightly wider at the base than the thorax, with narrow reflexed margins, nearly parallel, finely but distinctly and very closely punctured ; under side and legs black ; prosternum longitudinally carinate. Hab. Santa Catharina, Brazil. There are two specimens of this insect before me, which, although they show some differences, I must refer to the same species. In one the head has only a few' punctures and the extreme basal margin of the elytra is stained with black, the colour of the elytra is also entirely pale fulvous; but in structure the two specimens agree entirely. The species is closely allied to |
