Show 610 MR. MARTIN JAOOBY ON NEW [Nov. 6, Var. o. Thorax with the anterior and posterior margins partly black, the rest of the surface unspotted. Length 3-31 lines. Head impunctate, the eyes large, the intermediate space narrower than their diameter, the frontal tubercles short and broad, bounded behind by a deep groove ; antennae slender, extending nearly to the middle of the elytra, the basal four and the apical two joints pale fulvous, the others black, the third and fourth joints equal; thorax a little more than twice as broad as long, the auterior and posterior margins nearly straight, the disc black, the sides rather strongly rounded, narrowed anteriorly, the anterior angles not produced outward, the surface impunctate, the sides rather broadly flattened ; elytra very finely and closely punctured, pale testaceous, with the extreme base and an elongate spot on each shoulder black; legs streaked with black above. Hab. Amazons, Ega. This is a rather variable species and one of those in which the eyes are larger than the intermediate space; in the normal form the disc of the thorax is black, but in many specimens only the anterior aud posterior margins are more or less marked with this colour; the femora are either spotted above with black as well as the tibiae, or are entirely testaceous ; the antennae also vary, having sometimes the first and the last joint testaceous only, or this colour is spread over several joints. OZPIONYCHIS TABIPA (Clk. Catal.). Pale testaceous, the head, breast, and the apex of the posterior femora black; thorax impunctate; elytra closely and distinctly punctured. Length 2 | lines. Head finely punctured, the vertex piceous, the labrum flavous, frontal elevations subquadrate; antennae fuscous, the basal three joints flavous, third joint scarcely shorter than the fourth; thorax with strongly rounded lateral margins, the anterior angles acute but not produced iuto a tooth, the surface impunctate, the scutellum piceous; elytra very closely and rather strongly punctured throughout; abdomen and legs testaceous, the posterior femora with a piceous spot at the apex, posterior claws piceous. Hab. Brazil. Of this species a siugle specimen, named by Clark, is contained in m y collection; the general colour is a uniform obscure testaceous, but the dark head, breast, and the femoral spot, as w^ell as the very close and rather strong elytral punctuation, will separate this species from others similarly coloured. ffiPIONYCHIS NIGROSCUTATA, n. sp. (Plate XXXVIII. fig. 3.) Robust, convex, black; head and thorax impunctate, the latter flavous with a central black spot; elytra testaceous, rather strongly punctured, the suture narrowly black. Length 4 lines. |
