MARTIN JACOBY ON NEW SPECIES [Nov. 28, Head piceous or black, the vertex coarsely punctured, the clypeus flavous; antennae black, the third and fourth joints very nearly equal; thorax strongly transverse, the sides strongly but not broadly flattened, the lateral margins rounded in front, anterior angles dentiform, the surface impunctate, flavous, with a very obsolete transverse sulcus near the base ; scutellum black ; elytra finely and closely punctured, bluish black, the discoidal flavous stripe of double the width of the similarly coloured lateral margins and connected with the latter at the apex; under side and legs black ; elytral epipleurae with a very narrow inner dark margin. Hab. Brazil. This banded species is more nearly allied to 0. figurata Chev. than to any other, and may be known by the dark head, antennae, and legs, the broad discoidal elytral flavous stripe, which has somewhat irregular outlines, and by the inner dark margin of the elytral epipleurae. The species, if these details be kept in view, cannot be mistaken for any of those of which v. Harold has given an analytical table (Berlin, ent. Zeitschr. 1881). O e d io n y ch is e x c l am a t io n is , sp. n. (Plate XY. fig. 3 .) Testaceous, the intermediate joints of the antennae black; thorax impunctate; elytra minutely punctured, two elongate spots at the base and a longitudinal stripe at the sides, strongly thickened at the upper end, black. Length 7 millim. Head impunctate; the eyes large, each as wTide as the intervening space; carina short and convex, narrow ; antennae testaceous, the sixth to the ninth joints blackish, third smaller than the fourth joint; thorax more than twice as broad as long, the sides strongly rounded and broadly flattened, the anterior angles produced into a small tooth, the surface impunctate; elytra not wider at the base than the thorax, with narrow reflexed lateral margins, extremely finely and closely punctured, testaceous, the base with two black longitudinal short stripes, the sides near the margins with another longer narrow black stripe, which ends anteriorly rather abruptly in a club or knob directed towards the suture; under side and legs testaceous. IIab. Brazil. I know of only a single specimen of this rather peculiarly marked species, the exact locality of which is unknown to me. O ed io n y ch is in ter r u p to -v it t a t a , sp. n . (P la te XY. fig. 6 .) Testaceous, the head and the intermediate joints of the antennae black ; thorax impunctate, the anterior angles mucronate ; elytra finely punctured, testaceous, each elytron with two more or less interrupted longitudinal black stripes ; the breast black. Length 6 millim. Of flattened shape ; the head impunctate, black, deeply foveolate between the eyes, the latter large, their diameter as wide as the |
