Show 400 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, head impunctate, frontal tubercles rather broad, clypeus short and ridge-shaped; eyes widely separated, comparatively small; antenna? pale fulvous, the third and following joints elongate and equal, terminal joints rather shorter; thorax slightly narrowed anteriorly, the sides broadly flattened, the margins scarcely rounded, the anterior angles outwardly produced into a distinct and rather large tooth, the surface entirely impunctate ; elytra with anteriorly rather broadly reflexed, lateral margins, without basal depression, very finely and closely punctured ; under side and legs rather darker than the upper surface, the metatarsus as long as the following two joints together, claw-joint strongly swollen. Hab. Brazil. Of this species, which may be known by the rather flattened general shape, the short thorax with its broadly flattened sides, and the entirely unicolorous upper and under sides, three specimens are contained in my collection without special locality. A sphjera fem o r at a , sp. n. Testaceous, the head and the breast piceous or black ; thorax nearly white, impunctate; elytra obscure testaceous, nearly impunctate ; posterior femora with a large white patch. Length 6-7 millim. Head with a few deep punctures near the eyes, the vertex nearly black, the lower portion testaceous ; eyes large ; antenna? obscure fulvous or fuscous, the joints rather robust, the third slightly shorter than the fourth ; thorax with the lateral margins obliquely narrowed anteriorly, feebly rounded, the anterior angles thickened and pointed but not dentiform, the anterior margin straight at the middle, the sides gradually flattened, the disc impunctate, yellowish-white, the sides sometimes stained with testaceous; scutelliun piceous ; elytra with a distinct basal depression, extremely minutely punctured when seen under a strong lens, obscure testaceous, the extreme sutural margins piceous; under side and the legs piceous, abdomen testaceous, the posterior femora with a large yellowish-white oblong patch at the outer portion, claw-joint moderately swollen. Hab. Pichinche, Colombia. A species not difficult to distinguish on account of the colour of the thorax and of the posterior femora ; there are five specimens, before me, which show no variation in this respect. A sph^e r a d isc ic o l l is , sp. 11. Black; thorax with broad sides, the latter testaceous, the disc black, impunctate, anterior angles pointed; elytra convex, widened posteriorly, impunctate, testaceous; breast, the legs, and the middle of the abdomen black, sides of the latter testaceous; posterior femora but moderately thickened. Length 8 millim. Of convex, posteriorly widened shape; the head black, im- |
