Hab. Brazil. Of this large species three specimens are contained in my collection. Amongst the longitudinally banded species described by von Harold in the Berl. ent. Zeit. 1881, there is none which can be compared in size with this species, and all similarly coloured forms have but one elytral stripe instead of two. 0. tceniolata Har. has the eyes widely separated, a small thorax, and narrow elytral epipleurse, and is much smaller. O e d io n y ch is a d ju n c t a , sp. n. (Plate XV. fig. 12.) Black; thorax impunctate, the margins flavous ; elytra impunctate, a subsutural vitta, the lateral margins, and a short transverse band near the apex, connecting the stripes, flavous. Length 5| millim. Head broad, black, closely and strongly punctured in front of the eyes, the latter small, very widely separated ; antennse very short, the joints moniliform ; thorax twice as broad as long, the lateral margins strongly thickened, narrowly sulcate in front, the anterior angles thickened, slightly produced, the disc impunctate, black, all the margins narrowly flavous ; scutellum black ; elytra without any perceptible punctuation, black, with the lateral margins and a narrow longitudinal stripe at the disc flavous; this stripe extends from the middle of the base to the apex and approaches slightly the suture below the middle, near the apex it is connected with the flavous margin by another oblique transverse thin stripe ; below and the legs black. Hab. Bolivia. Amongst the species with pale longitudinal stripes, the present one seems most nearly allied to 0. haagi Har. in colour and pattern, but differs in the entirely impunctate thorax and elytra. Oe d io n y ch is d o n c k ie r i , sp. n. Elongate and parallel, the head fulvous; antennfe and breast more or less black; thorax flavous, impunctate; elytra finely punctured, obscure flavous, a sutural and a discoidal longitudinal band black ; legs dark fulvous. Length 7 millim. Head rugosely punctured above the eyes, fulvous; frontal elevations strongly raised, broadly trigonate ; clypeus short and broadly convex between the antennfe; the latter robust, extending to the middle of the elytra, black, the basal two joints piceous, third and fourth equal, the terminal joints more elongate ; thorax rather more than twice as broad as long, not or scarcely narrowed in front, the sides rounded, with a well-marked sulcus, the anterior angles acute but not produced, the disc transversely grooved near the base, impunctate, flavous, rather opaque |
