Show 590 MR. M. JACOBY O N PHYTOPHAGOUS COLEOPTERA. [Nov. 16, a black transverse sinuate fascia at the apex, surrounding flavous apical spot. Length 5 lines. Head distinctly punctured in front of the eyes, black ; lower part of the face deeply excavated, that portion, as well as the anterior margin of the clypeus and labrum, flavous; two testaceous spots are placed near the upper part of the eyes. Antennse rather long, extending further than the base of the thorax, fulvous, the first four joints black above. Thorax impunctate, of usual shape. Elytra moderately deeply and closely punctured, coloured like the thorax ; the apex of each elytron occupied by a black narrow band in the shape of a ring, the upper portion of which is widened towards the lateral margin; the space within this ring is of a light testaceous or yellowish colour, as well as a convex narrow band above the black marking ; the elytra may also be described as light flavous at their last third, interrupted by a black ring near the apex; a short lateral streak of flavous extends also from the shoulders downwards. Underside testaceous ; sides of the breast and base of the mesothorax black; legs fulvous, tarsi and claws piceous. Mus. Godman and Salvin. 7. MASTOSTETHUS SUAVIS, Bates. Of this species, two specimens were collected by Mr. Buckley. The elytra have four black spots each, of which the two anterior ones are longitudinal and oblique, the others transverse, but isolated in the specimens from Ecuador, and not connected in shape of a ring, according to Mr. Bates's description of his type. Genus AGATHOMERUS, Lacord. 8. A G A T H O M E R U S SIMPLICIPENNIS, sp. nov. Elongate, parallel. Flavous-testaceous ; shining, a transverse band at the vertex, labrum, antennse, part of the anterior femora, and the tibiae and tarsi black. Length 5 lines. Head deeply punctured near the eye, the rest impunctate ; flavous, with a broad black band between the eyes. Antennae extending to the base of the thorax, black, the first four joints shining, the rest pubescent. Thorax transverse, sides nearly straight seen from above ; disk with a transverse groove near the anterior and posterior margins, the former slightly arched at each side, the latter nearly straight; surface glabrous, impunctate, fulvous, margined anteriorly and posteriorly with testaceous. Scutellum trigonate, its apex rounded. Elytra closely but rather finely punctured, the punctures much more distant towards the apex, coloured like the thorax. Underside of the same colour, the femora rather darker ; hinder tibiae distinctly curved, covered, like the rest of the underside, with long testaceous hairs. Mus. Godman and Salvin. |
