Black, the lower portion of the face and the thorax reddish fulvous, the latter very minutely punctured ; elytra opaque, black, closely and more distinctly punctured than the thorax; legs black. Length 3 millim. Head broad, impunctate, the vertex black, the lower portion in shape of a large subquadrate patch, fulvous, frontal elevations very broad; carina rather blunt, anterior edge of the clypeus straight; antennae robust, extending to about the middle of the elytra, black, the second and third joint small, equal, third and following joints thickened, about twice as long as broad; thorax twice as broad as long, convex, the sides rounded, the posterior angles rather oblique, the surface extremely minutely punctured, reddish fulvous ; scutellum black ; elytra slightly broader at the base than the thorax, very slightly narrowed posteriorly, black, opaque, closely and finely punctured; below and the legs black, posterior femora strongly incrassate ; the tibiae with a long spine; the metatarsus as long as the following two joints together. Hab. Dunbrody, Cape Colony (Rev. J. O'Neil). Distinguished by the opaque black elytra, antennae, and legs, and the colour of the head ; the eyes in this species are, however, much more distantly placed than in the other members of the genus, and the posterior angles of the thorax are less rounded: all other characters agree with the typical species. DECARIA OBSCURA, sp. n. Below and the legs pale fulvous, above obscure dark fulvous, antennae (the basal joints excepted) black ; thorax extremely minutely, elytra more distinctly punctured, the punctures arranged in very close semiregular rows ; antennae ten-jointed. Length 2 millim. Head impunctate, obscure fulvous or piceous, frontal elevations transverse, broad ; carina distinct; antennae closely approached at the base, black, the lower two joints fulvous, second joint very small, third and following joints triangularly dilated, rather broad and robust; thorax scarcely twice as broad as long, the sides rounded, the anterior angles slightly obliquely thickened, basal margin distinctly concave in front of the scutellum, the disc obscure dark fulvous, with a few minute punctures ; scutellum broad, impunctate ; elytra distinctly wider at the base than the thorax, slightly widened towards the middle and gradually narrowed posteriorly, the apex rounded, the surface convex, subcylindrical, rather strongly punctured in closely approached semiregular rows ; posterior femora strongly incrassate ; posterior tibiae with a long spine, their metatarsus as long as the following two joints together. Hab. Rhobomp, Sierra Leone. This cannot be D. tricolor Weise from the same locality, as the author describes the antennae as yellowish brown and the elytra aa |
