Show 252 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, very finely punctured, with the anterior fourth portion black. Three specimens are before me, which do not differ from each other. SPHiERODERMA MASHONANA, sp. n. Subglobulose, reddish fulvous, the apical joints of the antenna' and the tibiae and tarsi black ; thorax extremely minutely and rather closely punctured ; elytra punctured like the thorax, the punctures irregularly placed. Length 4 millim. Head impunctate, the clypeus deflexed anteriorly, with a distinct central longitudinal carina; eyes very large ; the antennae extending to the base of the thorax only, flavous, the terminal five or six joints fuscous, subtriangularly dilated, the last strongly pointed ; thorax nearly three times broader than long, the sides feebly rounded, with a very narrow margin, the anterior angles rather thickened and obtusely rounded, the posterior margin broadly produced at the middle, sinuate at the sides, the surface closely and very finely punctured ; scutellum triangular, pointed; elytra subglobular, evenly and very strongly convex, the shoulders rounded and slightly prominent, the punctures not or scarcely-larger than those of the thorax, irregularly distributed and here and there arranged in lines, those near the lateral margins nearly obsolete; elytral epipleurae extremely broad and concave ; legs and the underside fulvous, the coxae and the tibiae and tarsi blackish ; prosternum elongate, constricted at the middle, strongly punctured. Hab. Salisbury, Mashonaland, M a y and October (67. Marshall). Resembling somewhat in size and shape the European Argopus ahrensi Gebl., but still more convex, the antennae very short and dilated, and the punctuation of its upper surface very fine. The present species is the largest of the genus known to m e from Africa. BLEPHARIDA REGULARIS, sp. n. Subquadrate ovate, fulvous ; head and thorax flavous, the latter minutely punctured; elytra strongly punctate-striate, the interstices costate at tbe sides, with numerous closely placed flavous spots, the lateral margins broadly flavous, spotted with fulvous. Length 5 | millim. Head very sparingly and finely punctured, flavous, with a deep semicircular groove in front of the eyes ; clypeus broad and flat; antennae not extending to the middle of the elytra, fulvous, the terminal six joints short and thick ; thorax more than twice as broad as long, narrowed anteriorly, the sides nearly straight, the anterior angles thickened, the surface extremely finely punctured, only visible under a strong lens, with two small round depressions near the lateral margins ; elytra with ten rows of deep and closely placed punctures, the subsutural one short, the punctures fulvous tbe interstices varied at regular intervals with fulvous and flavous |
