Head finely punctured, the interstices minutely granulate, the sides at the base of the antennae raised in shape of a ridge ; antennae filiform, black, the basal three joints more or less fulvous, the first joint metallic blue above, third joint but slightly longer than the second but shorter than the fourth, the following joints slightly thickened; thorax twice as broad as long, slightly narrowed anteriorly, the sides strongly rounded, with a narrow margin, the anterior angles produced into a short tooth, the surface very finely and rather closely punctured and minutely granulate ; scutellum subquadrate, truncate at the apex; elytra subcylindrical, much more strongly punctured than the thorax, the punctuation arranged in closely approached rows, the interstices with a few- minute punctures here and there, dark violaceous blue, the sutural margin greenish ; below and the legs dark metallic blue, finely pubescent, tbe anterior femora with a very minute, the posterior with a more distinct tooth ; prosternum widened at the base, the anterior margin of the thoracic episternum concave. Hab. Salisbury, Mashonaland (67. Marshall). Allied to 0. discolor Lefev., but in that species the labrum, palpi, antennae, and the legs are brown and the thorax is described as densely punctured ; tbe present insect, on account of the concave margin of the thoracic episternum, the entire tibiae, appendiculate claws, and other details, possesses all the characters peculiar to the genus. LEFEVREA BRUNNEA, sp. n. Entirely pale fulvous, the head and thorax rather strongly and closely punctured ; elytra closely punctate-striate, the punctures very fine towards the apex. Length 3 millim. Of the general shape of a small species of Colaspis; the head finely punctured on each side, the clypeus contiguous with the face, its anterior margin moderately emarginate in the middle and on each side, its surface sparingly punctured ; antennae extending to about the middle of the elytra, fulvous, the intermediate joints sometimes stained with fuscous, the third and fourth joints equal, one half longer than the second joint, terminal ones slightly thickened ; thorax twice as broad as long, the sides rounded, the anterior and posterior margins straight, of equal width, the angles acute, the surface closely and somewhat strongly punctured, the punctures more crowded at the sides, the latter with an obsolete depression, scutellum with the sides rounded; elytra not wider at the base than the thorax, convex, punctured in closely approached rows, the punctures themselves scarcely larger than those of the thorax; below and the legs fulvous, the latter unarmed ; claws appendiculate ; prosternum strongly narrowed between the coxae. Hab. Salisbury, Mashonaland (67. Marshall). Distinct from all its allies in the uniform pale fulvous coloration. PROC ZOOL. Soc-1900, No. XVI. 16 |
