Show 1903.J SOUTH-AMERICAX COLEOPTERA. 37 regularly punctate-striate, testaceous, the basal margin, a broad sutural band, connected with a transverse band before the middle and extending downwards, and the lateral margins narrowly aeneous. Length 12 millim. Head with a few very minute punctures, dull aeneous; antenna? black, the lower two joints fulvous below, the terminal joints widened (the last two joints wanting); thorax twice as broad as long, the lateral margins straight, the anterior angles acute, pointed, the surface of the same colour as the head and similarly sculptured, opaque; elytra with their greatest elevation near the base, punctured in very regular rows, the punctures rather elongate in shape, piceous, the ground-colour flavous, the lateral margins very narrowly and the suture broadly dark aeneous, the base with a narrow aeneous stripe extending to the middle of the width of the elytra, followed by a broad transverse aeneous band which at each end curves downwards at right angles to below the middle, this downward branch is rather suddenly constricted at its middle; underside and legs metallic aeneous, shining ; mesosternal process moderately long and straight. Hab. Peru. (A single specimen.) DORYPHORA ECUADORIEXSIS, Sp. nOV. Black, thorax closely and finely punctured; elytra flavous, strongly, closely, and irregularly punctured, the suture greenish black, a transverse spot at the shoulders of triangular shape, a small sutural spot, another below the middle, and a curved elongate stripe at the sides bluish black. Length 10 millim. Head closely and finely punctured ; antenna? short, black, the basal two joints flavous below, terminal joints gradually and but little widened, the last joint long; thorax black, with a slight greenish tint, the anterior angles acute but not tuberculate, the disc very closely punctured at the sides and the base, the punctures of different size, middle of the disc sparingly punctate, the sides with an obsolete depression ; scutellum triangular, greenish black ; elytra rather pointed at the apex, flavous, very closely and strongly punctured, especially so at the sides, the punctures of piceous colour, irregularly placed with some indications of rows near the suture, the latter greenish black, the shoulders with a transverse triangular spot, nearly connected with another small sutural spot below the base, a curved elongate, posteriorly narrowed stripe at the sides, and another small subsutural spot, both below the middle, blackish; underside and legs greenish black, the mesosternal process rather short. Hab. Ecuador. (A single specimen.) This is not a variety of D. instabilis Stal, which the species resembles somewhat, as the elytral sculpturing as well as that of the thorax are quite different. |
