Show 1900.] FROM SOUTH AND CENTRAL AFRICA. 253 spots, the last interstice near the margins broad, flavous, crossed from the middle downwards with fulvous stripes. Hab. Africa. Whether this is the species described by Thuuberg as Podontia stolida I a m not certain, the description is not detailed enough to be sure about it; the terminal joints of the antennae are given as black and the thorax as impunctate ; the position and number of the elytral spots are not mentioned. The present species differs from all its African congeners with which I a m acquainted in the regular or semiregular numbers of the flavous spots, which form no bands or other pattern, but are distributed evenly and closely on every interstice ; I possess three specimens, which show no differences in that respect, but have no exact localities. DlBOLIA BIMACULATA, Sp. 11. Bluish black, above metallic blue, the basal joints of the antennae flavous ; thorax closely semirugose-punctate; elytra finely and closely punctate-striate, each elytron with a fulvous spot near the apex. Length 2 | millim. Of convex, subcyliudrical shape; the head with a few fine punctures, metallic greenish; clypeus triangularly raised; eyes elongate and large ; antennae scarcely extending to the middle of the elytra, black, the lower five joints flavous, the basal joint stained with piceous above, elongate, slender, the second as long as the third joint, terminal joints gradually and moderately thickened; thorax about twice as broad as long, the sides nearly straight, obliquely narrowed towards the apex, the anterior angles very slightly thickened, the surface irregularly wrinkled, rather finely and closely punctured ; scutellum small, triangular, black ; elytra very closely and finely punctate-striate, the rows rather irregular here and there ; each elytron with a large, subquadrate, slightly oblique fulvous patch near the apex ; femora metallic blue; tibia? and tarsi black, posterior tibiae strongly widened towards the apex, the edges dentate, the apex with a robust, double-pointed fulvous spur ; the metatarsus slender, as long as the following two joints together. Hab. Malvern, Natal (67. Marshall). I received a single specimen of this pretty little species from Mr. Marshall. DlBOLIA AFRICAN A, sp. n. Dark metallic greenish, the antennae black ; thorax strongly and remotely punctured; elytra strongly and very closely punctured in irregular rows. Length 3 millim. Head finely and remotely punctured, the eyes widely separated, frontal elevations feebly raised; clypeus convex, triangular; antennae extending to the base of the elytra, black, the lower three joints more or less stained with fulvous, the second, third, and fourth |
