MARTIN JACOBY ON NEW SPECIES [Nov. 28, ancl very strongly thickened at the anterior angles, the latter produced but not dentiform, the surface impunctate, nearly white ; scutellum dark brown ; elytra of the same colour or dark fuscous, shining, impunctate, each with two white markings, the first at the middle in shape of a transverse band not quite extending to either margin, the second of rounded shape, near the apex; the breast piceous ; the legs dark fulvous ; the abdomen testaceous or flavous ; claw-joint rather strongly swollen ; prosternum very narrow and parallel. Hab. Colombia. In some specimens the ground-colour of the elytra is much paler. The absence of a thoracic flattening of the sides and the position and colour of the elytral markings distinguish this species. A sp h ^er a b ip l a g ia t a , sp. n . Black, thorax and the femora flavous ; elytra nearly impunctate, the lateral margins, a large discoidal patch, and the apex flavous; apex of the posterior femora black. Length 5-6 millim. Head black, with one or two punctures near the eyes ; antennae black, the lower two joints flavous below, third and following joints nearly equal; thorax nearly twice as broad as long, the sides rounded anteriorly, with a broad flattened sulcus, the anterior angles thickened but not produced, the surface impunctate, flavous ; scutellum black; elytra impunctate ; under side, the apex of the posterior femora, and the tibiae and tarsi black, rest of the femora flavous. Hab. Brazil. This Asphcera resembles almost exactly A. episcopalis 111. in the elytral pattern, which consists of a transverse black band at the base and another near the apex connected by a very narrow sutural stripe, the disc in shape of a large oval patch and the apex as well as the lateral margins being flavous. The differences which separate this species are: the entirely black head, without the whitish frontal tubercles; the anterior angles of the thorax, which are not produced ; the position of the posterior elytral band, which is placed much lower down than in the above-named species; and the colour of the legs. I have received several specimens from the La Plata Museum without a special locality. A sphcera e r ic i iso n i , sp. n. Black; thorax testaceous, the sides straight, the surface impunctate; elytra nearly black, the lateral margins and an extremely narrow transverse straight band at the middle flavous. Length 6 millim. Head with a few punctures above the eyes, black, the frontal elevations very broad and flat, scarcely raised, the base of the antennae flavous; the antennae very long and slender, black, the fourth joint longer than the third ; thorax only about one- |
