Show 434 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, short and transverse, the sides rounded and broadly flattened, the anterior angles acute but not dentiform, the surface entirely impunctate, testaceous; scutellum piceous; elytra with broadly flattened margins, slightly widened at the middle, finely and closely punctured, testaceous, with two broad fulvous transverse bands one at the base, deeply concave at its lower margin and connected by a sutural stripe with the second band near the apex of obliquely subquadrate shape, both bands are interrupted at some distance from the lateral margins and are more or less distinctly edged with piceous, the basal margin especially so; under side and legs testaceous. Hab. Argentine R. and Brazil. Not unlike 0. pustulata Jac. in coloration, but the antennae differently coloured, the thorax without a fulvous spot, and the elytral bands of different shape. O e d io n y ch is c a t h a r in a , sp. n. Dark fulvous below, antennae black; thorax flavous, impunctate ; head and scutellum dark fulvous; elytra rather strongly and closely punctured, dark fulvous, a large discoidal ovate patch on each, flavous. Length 6 millim. Of rather elongate and parallel shape; the head impunctate, fulvous, deeply grooved between the eyes, the latter large, frontal elevations broad, transverse; carina blunt and thick; antennae robust, black, third joint distinctly shorter than the fourth; thorax strongly transverse, the lateral margins distinctly rounded, the anterior angles but slightly produced outwards, scarcely toothed, lateral sulci broad and deep, the surface impunctate, flavous; elytra with narrow reflexed margins, fulvous, distinctly punctured, the disc occupied by a large flavous ovate patch, with its narrowest portion near the suture ; under side and legs dark fulvous, the tibiae and tarsi blackish; metatarsus very short, claw-joint strongly inflated. Hab. St. Catharina, Brazil. Of somewhat similar coloration to 0. 4-pustulata Jac. from the same locality, but the thorax without fulvous spot, the antennae entirely black, with more elongate joints, and tlie whole apex of the elytra fulvous; the thoracic sulci in the present species also are wider and deeper. O e d io n y ch is o c el la ta , sp. n. (Plate XY. fig. 10.) Black, thorax testaceous, with three black spots; elytra closely and strongly punctured, each elytron with six small flavous spots (1.2.2.1). Length 5 millim. Head not perceptibly punctured, the middle black, the sides and the anterior portion testaceous, frontal tubercles short and broad, strongly raised, carina broad; antennae rather short and robust, black, the lower three joints more or less flavous, third joint more |
