Hab. Paraguay. A rather small and well-marked species, of which I possess a single specimen only. Elytra with elongate spots or longitudinal black or flavous bands. O ed io n y ch is h um b o l d t i , sp. n.

Head black or nearly so, impunctate, the frontal elevations broad, trigonate, clypeus perpendicularly deflexed ; antennae robust, fulvous, the third joint smaller than the fourth ; thorax narrowed in front, one-half broader than long, the sides straight, broadly flattened, the anterior angles produced into a small tooth, the surface impunctate, testaceous ; scutellum testaceous; elytra nearly parallel, closely and distinctly, although finely punctured, testaceous, each elytron with two more or less elongate black spots at the base and two others below the middle-of the basal spots, one is placed on the shoulders and extends nearly down to the middle, the other shorter one is placed near the suture ; the posterior spots are almost joined, the outer one being of more elongate shape than the inner; under side and legs testaceous, breast black. Hab. Bolivia. This Oedionychis is well distinguished by the straight lateral margins of the thorax, which are obliquely narrowed anteriorly, and by the four elytral spots.
