Hab. Peru. The comparatively long thorax, the neai'ly straight and but slightly flattened sides, in connection with the very narrow and straight elytral pale band at the middle, well distinguish this species from others similarly marked. A s p h /e r a m a c u l ic o l l is , sp. n. Black, the antenna; obscure fulvous ; thorax pale testaceous with a transverse piceous band, the sides straight; elytra entirely impunctate, metallic green, the lateral margins and a transverse narrow band at the middle flavous ; claw-joint distinctly swollen. Length 5 millim. Smaller than the preceding species; the elytra more widened at the middle, with a broader lateral reflexed margin ; the head with a single puncture close to the eyes, black at the vertex, the lower portion stained with flavous, the frontal elevations broad, tri-gonate, divided by a deep narrow groove; clypeus strongly raised ; antenna? dark fulvous, the third and fourth joints very elongate, the following joints shorter; thorax with nearly straight lateral margins, the sides flattened, the anterior angles mucronate; the disc impunctate, whitish, with a narrow transverse piceous band ; scutellum black; elytra with broad flattened lateral margins, impunctate, metallic green, the flattened sides and a transverse narrow band at the middle pale yellowish; below and the legs black; metatarsus elongate; claw-joint distinctly thickened. Hab. Peru, Marcapata. Separated by the sculpture and colouring of the head and that of the antennse, the thoracic transverse band, and colour of the elytra. The general size is smaller than that of the allied species. A. nobilitata Fab. is of different coloration, although the elytral pattern is similar and the claw-joint is scarcely swollen. A. clisco-fasciata Baly is another closely allied species, but has differently coloured antenna;, rounded sides of the thorax, finely punctured elytra, and their transverse band broad, not narrow. A sp h ^ e ra a p i c a l i s , sp. 11. Black or piceous, the basal joints of the antenna? and the clypeus flavous; thorax impunctate, fulvous or flavous; elytra greenish-aeneous or purplish, impunctate, the lateral margins, a transverse band at the middle, a spot near the scutellum, |
