Show 1899.] PHYTOPHAGOUS C O L E O P T E R A O F AFRICA. 377 than long, the sides rounded anteriorly, constricted at the base, the disc deeply transversely sulcate, impunctate, the anterior portion with some miuute punctures, the sulcation not extending to the sides ; elytra with the basal portion feebly raised, extremely minutely punctured near the suture only, the rest of the surface impunctate ; beloAv and the legs flavous, the metatarsus of the posterior legs as long as the following joints together, tibias unarmed; anterior coxal cavities closed. Hab. Lindi, Africa (Bang-Haas). The single male specimen which I received from Herr Bang- Haas with the above locality, which is unknoAvn to me, is of a purplish fulvous or reddish colour above and agrees in the excavate head Avith many other species of the genus, but the structure of the excavation differs from that of the allied species; the palpi are robust. MACEIMA AFRICANA, sp. n. (Plate XXI. fig. 9.) Flavous ; the base of the head, the antennas, and the abdomen black ; thorax bifoveolate, impunctate ; elytra closely punctured and rugose and sparingly pubescent, metallic blue ; legs flavous. Length 7 millim. Head flavous, the vertex bluish black, impunctate, the frontal tubercles narrowly transverse, the clypeus depressed at each side; penultimate joint of the palpi thickened, elongate ; antennae long and slender, black, the basal joint flavous below, second very small, third as long as the first joint, the f olloAving slightly shorter ; thorax subquadrate, one-half broader than long, distinctly narrowed at the base, the angles acute but not prominent; the disc bifoveolate, impunctate, flavous; scutellum black; elytra narroAviy elongate, metallic blue, closely punctured and finely rugose, their epipleuras broad and continued below the middle; legs elongate, flavous, tibias mucronate, the first joint of the posterior tarsi longer than the following joints together ; claws appendiculate ; anterior coxal cavities closed ; abdomen black. Hab. Salisbury, Mashonaland (67. Marshall). This insect agrees almost entirely in coloration with one described by Chapuis as Xenarthra orphana, from Abyssinia; but in that species the antennae are entirely flavous, the tibia are unarmed, and the general size is smaller. CANDEZEA PUNCTATO-LINEATA, sp. n. Black, the basal joints of the antennas and the thorax and legs fulvous; head and thorax impunctate; elytra black, fiuely punctured in closely approached semiregular rows. Length 4 millim. Elongate, narrow and con\rex in shape; the head blackish, opaque, entirely impunctate, the clypeus flavous ; antennas slender, the basal joint long and curved, the second short, the third twice the length of the second, the remaining joints slightly shorter, the basal five joints flavous, the others piceous ; thorax tAvice as |
