Show 408 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, The comparatively small width of the thorax and the widely separated elytral green bands, in connection with the fulvous head and antenna?, distinguish this species, which is evidently closely allied to A. oblecta Baly; but the head has no punctures nor hairs, the thorax is certainly not " more than twice as broad as long," and the elytra are not furnished with hairs at the apical margins. A sph ^e r a d im id ia t ic o r n is , sp. n. Flavous, head piceous, the intermediate joints of the antennae black; thorax flavous, impunctate; elytra not perceptibly punctured, pale flavous, a transverse band at the base and a broader one below the middle metallic green; legs fulvous. Length 6 millim. Head impunctate, the vertex piceous; frontal elevations strongly raised, pyriform; clypeus flavous, semicircular, with an acute central ridge; eyes very large, the diameter of each laager than the dividing space ; antennae long and slender, the lower and the apical three joints fulvous, the rest black, third and fourth joints very elongate, equal, apical joints shorter ; thorax twice as broad as long, slightly narrowed anteriorly, the anterior angles pointed but not produced, lateral margins evenly rounded, preceded by a broad sulcation, the surface impunctate, flavous; scutellum fulvous; elytra widened at the middle, yellowish-white, with two broad transverse metallic - green bands, not extending to the lateral margins, the first extending from the base to nearly the middle, the second immediately below the latter and abbreviated at some distance from the apex, both bands are of nearly subquadrate shape; the breast and the legs pale fulvous, abdomen flavous, the tarsi obscure piceous; the metatarsus moderately elongate, claw-joint strongly swollen. Hab. Ecuador. Distinguished by the colour of the head and the antennae, the large eyes and broad elytral bands, pale legs, &c. ASPH^ERA DEJEANI, Sp. 11. Black; thorax impunctate, testaceous, the entire disc black; elytra impunctate, testaceous, a broad band at the base and another below the middle, not extending to the lateral margins, metallic blue ; claw-joint scarcely swollen. Length 8 millim. Head with some punctures near the eyes, black, frontal elevations strongly raised, narrow and transverse; antenna? extending beyond the middle of the elytra, black, all the joints elongate and slender, the third and fourth equal; thorax twice as broad as long, the lateral margins scarcely rounded, the anterior angles more than usually produced and pointed (in one specimen to a much smaller extent), anterior margin concave, the sides broadly but not deeply sulcate, testaceous as well as the extreme base, the rest of the surface occupied by a transverse black band; scutellum black |
