Show 1900.] FROM SOUTH AND CENTRAL AFRICA. 247 metallic blue, the interstices slightly wrinkled, the space near the lateral margins deeply sulcate and flavous, this colour also extending to the apical margins ; below and the legs fulvous, apex of the posterior femora piceous, posterior tibia with a distinct spine ; the metatarsus as long as the following joints together. Hab. Angola. T w o specimens of this very well-marked and distinct species are in m y collection. APHTHONA MINUTA, sp. n. Winged, entirely pale flavous or testaceous, the apical joints of the antennae black ; thorax impunctate ; elytra scarcely perceptibly punctured in irregular rows. Length 1 millim. Head impunctate, the frontal elevations distinct, bounded above by oblique grooves, carina acute and rather narrow; antennae two-thirds the length of the body, the lower four joints flavous, the rest black, the second and third joints small, equal, the following slightly longer, terminal joint more elongate and feebly thickened ; thorax one-half broader than long, slightly narrowed in front, the sides nearly straight, the surface somewhat depressed, with a very obsolete transverse depression near the base, entirely impunctate; elytra scarcely wider at the base than the thorax, parallel, the apex rounded, the surface with microscopically fine rows of punctures ; posterior femora strongly incrassate, tibiae dilated at the apex; the first joint of the posterior tarsi as long as the following joints together. Hab. Dunbrody, Cape Colony (Rev. J. ONeil). Many specimens. One of the smallest species of the genus, perhaps most nearly allied to the European A.pallida, but of entirely uniform coloration with the exception of the antennae; the penis is of parallel shape neither constricted nor widened, and with the apex broadly rounded, ending in a small point. SERRAPHULA ELONGATA, sp. n. Elongate, narrowed posteriorly, piceous below, above greenish aeneous, the antennae and the legs (the posterior femora excepted) fulvous ; thorax coarsely and closely punctured; elytra closely punctate-striate, the interstices longitudinally costate. Length 2 millim. Head impunctate, the frontal elevations trigonate, undivided; the clypeus strongly raised into a triangular ridge, which extends upwards between the antennae ; palpi rather slender; antennae extending to the apex of the elytra, fulvous, the basal joint moderately long and stout, the second and third short, equal, the following joints gradually elongate and slightly thickened ; thorax subquadrate, one-half broader than long, all the margins straight, the angles not produced, the surface closely and strongly punctured; scutellum broader than long; elytra rather long and convex, slightly widened towards the middle, rather pointed towards the apex, the 17* |
