Black, above flavous, head and the disc of the thorax greenish black, the latter extremely minutely punctured ; elytra strongly and semiregularly punctured, each elytron with ten obscure aeneous elongate spots (4, 3, 3) placed transversely below the base and below the middle. Length 12 millim. Oblong, the greatest convexity placed at the middle of the elytra; the head sparingly and finely punctured, with a small flavous spot at the vertex; antenna? nearly extending to the base of the thorax, black, the lower four joints flavous below, terminal joints distinctly widened ; thorax more than twice as broad as long, the sides rounded anteriorly, the angles acutely pointed, the surface flattened at the sides, exceedingly finely and closely punctured ; the disc, in shape of a large transverse patch, greenish black, the anterior and lateral edges of the patch sinuate, the rest of the surface flavous ; scutellum black; elytra closely and strongly punctured in irregular rows, which are slightly arranged in pairs near the suture, flavous, with ten elongate blackish-aeneous spots arranged in three transverse rows, one below the base consisting of four spots, of which one occupies the shoulders, the second row below the middle composed of three spots, the outer one of which is strongly transverse in shape, and the third row of three small spots near the apex. Hab. Espirito Santo, Brazil. (A single specimen.) This species might easily be mistaken for D. fasciato-maculata St., which it resembles almost entirely in coloration and pattern, but is much larger, the thorax is much more transverse and is devoid of the small spot placed at each side of the larger patch as in the above-named species, the elytra have the punctation less regularly and less distinctly geminate. In all specimens of D. fasciato-maculata I have seen the thoracic central patch extends quite to the anterior margin; in the present insect the latter is flavous like the sides, in both species the suture is narrowly aeneous as well. DORYPHORA LATERALIS, Sp. nOV. Olivaceous green, more or less stained with testaceous below, antenna? entirely testaceous ; thorax very minutely and sparingly punctured ; elytra strongly punctate-striate, the extreme basal margin and a sutural stripe dark fulvous, the ninth interstice obscure flavous. Length 15 millim. Subglobular, deflexed posteriorly, the head impunctate, the labrum testaceous ; antenna? slender, the terminal joints scarcely thickened, entirely testaceous ; thorax twice and a half broader than long, the sides straight at the base, rounded anteriorly, the anterior angles broad and produced but not mucronate, the disc convex, dull green, subopaque, with some minute punctures, the |
