Show 406 MR. MARTIN' JACOB Y OX NEW SPECIES [Nov. 28, intermediate joint slightly widened ; thorax with nearly straight sides, slightly narrowed anteriorly, anterior angles thickened and produced into a short point, the sides flattened but gradually so, without deep accompanying groove, the disc impunctate, fulvous or flavous, anterior margin rather deeply concave; scutellum black; elytra gradually and slightly widened posteriorly, with a short but rather deep sutural depression below the base, impunctate, pale testaceous, with two metallic dark purplish bands, the first subquadrate at the base, nearly extending to the middle but not to the lateral margins, its posterior edge straight, the posterior angles rounded, the second band occupies the entire apex and has its anterior angles rounded, these bands are separated by the testaceous ground-colour in shape of a transverse band of nearly similar size as the dark ones; under side and legs black, apex of abdomen flavous; claw-joint not strongly thickened. Hab. Peru. Principally distinguished by the position and shape of the posterior band in connection with the flattened sides of the thorax. A sph /era g l a b r ip e n n is , sp. 11. Obscure testaceous ; the thorax with gradually flattened sides, impunctate; elytra impunctate, with a metallic blight green sub-quadrate spot at the base and another one near the apex; posterior femora with the apex black. Length 7-10 millim. Of elongate and flattened shape, of a rather dirty testaceous; the head finely punctured at the sides as well as the space in front of the eyes, the frontal elevations broad, clypeus rather strongly raised; antennae long and slender, obscure testaceous, the terminal joints very elongate ; thorax with gradually flattened sides, narrowed anteriorly, the anterior margin deeply concave, the sides nearly straight, anterior angles in shape of a small tooth, the surface impunctate; scutellum testaceous; elytra entirely impunctate, with two brilliant metallic green bands or patches, the first at the base, not extending to the sutural or lateral margin and downwards to about one-tliird the length of the elytra, the other band of more rounded shape near the apex, not extending to either margin ; below finely pubescent; the apex of the posterior femora black ; claw-joint moderately swollen. Hab. Marcapata, Peru. I would have referred this species to A. chapuisi Har., but the author gives the colour as rufo-testaceous and the elytra as finely punctured, but even with a strong lens I cannot discover any punctuation. A sp h ^ e ra fu n e r e a , sp. 11. Black ; thorax whitish or obscure testaceous, the flattened sides well separated; elytra very minutely punctured, coloured like the thorax, a broad transverse band at the base and another still |
