[Received January 9, 1904.] (Plate XVII.*> The following descriptions are based on new species from different pax-ts of Africa and contained in my collection, which were sent to me for identification by Mx-. Cecil Barker of Malvern, Natal, tlxe Rev. J. A. O'Neil of Cape Colony, Dr. Brauns of the same place, and Mr. Sheppard of Beira. The present paper deals with the first groups as far as the Chrysomelince; the rest of the Phytophaga will form the subject of another contribution. CRIOCERIN^E. L E M A WEISEI, sp. n. Underside and antenna3 and legs black, upperside dark brown; thorax with several rows of very fine punctures at middle of disc, otherwise impunctate ; elytra with a sutural depression at the base, deeply punctate-striate, the interstices costate posteriorly. Length 7 millim. Head constricted behind the e}^es, with two highly raised, deeply divided, and sparingly pubescent tubercles, dark brown, the anterior portion black ; eyes large and prominent, deeply notched ; antenna? not extending to the middle of the elytra, the third and fourth joints equal, terminal joints slightly thickened ; thox-ax scarcely longer than broad, the sides not strongly constricted, with the usual deep fovea which gradually diminishes towards the disc, the base deeply transversely sulcate, the surface with three or- four rows of fine punctures at the middle, anterior angles slightly tuberculiform ; elytra, with a more or- less deep depression below the base near the suture, strongly punctate-striate, the first row of punctures double at the anterior portion, the interstices near tlxe apex strongly costate and closely approached; below finely pubescent. Hah. Lambarem, Fr. Congo (Coll. Belgian Mus. and m y own). This is another and no doubt quite distinct species belonging to the group of L. ctrmata Lac, L. hottentota Lac, and Z. macro - dera Weise. The sculpturing of the thorax is quite different, inasmuch as there is scarcely any punctuation excepting the median rows, and these are vex-y fine; there is also an entire absence of axxy transverse wrinkles, and the antenna? ai'e much longer- than in L. cephalotes Lac. I have received several specimens of this species from M. Clavareau. LEMA CYANEOPLAGIATA Jac Var. Elytra metallic blue, the apex, in shape of a triangular spot, testaceous. * For explanation of the Plate, see p. 270. |
