T R A N S V A A L : Leydenburg (T. Ayres). 26. SCIOBIUS VIDUUS, sp. nov. (Plate XIX. fig. 1.) Long. 8$, lat. 4f-4J m m. Head transverse, almost plane above, rugosely punctured and with fine scaling; forehead not impressed ; eyes slightly prominent. Rostrum longer than broad, the basal margin sharply angulate, sides subparallel, gena? rounded and scarcely dilated; upper surface plane, rugosely punctured, tricarinate, the outer carina? straight and parallel to near apex, then gently diverging. Antennce moderate, piceous, with thin grey pubescence; scape comparatively slender, subcompressed, only slightly curved about middle and gradually thickened to apex ; funicle with the first and third joints subequal. Prothorax moderately transverse, subtruncate at base, apex distinctly narrower and faintly sinuate, sides scarcely rounded, broadest at base and gradually narrowing to apex ; upper surface slightly convex, moderately closely set with distinct low granules and with a faint ill-defined impression on each side a little behind middle; colour black, with fine pale scaling which is denser laterally and beneath. Elytra broadly subpyriform, slightly sinuate at base, sides rounded, broadest well behind middle; upper surface broadly depressed and very steeply declivous posteriorly, with broad stria? containing rows of large shallow punctures separated by small granules, the intervals rather narrow, slightly convex and strongly coriaceous ; colour black or castaneous, with thin pale scaling dorsally and a broad uniform lateral band of denser scaling. Legs moderately long and lather slender, piceous or castaneous, with fine pale pubescence, the anterior tibia? straight. T Y P E 2 in the British Museum. TRANSVAAL. This species is founded on two females sent m e by Dr. W . Horn. It is nearly allied to marginatus Fahr., from which, however, it may at once be distinguished by the very differently shaped elytra, the more coarsely punctured stria?, and the much less curved scape. 27.

Head strongly transverse, piceous, with a few short pale setae, aciculate on vertex; forehead finely plicate, without any central impression or supra-ocular tubercle ; eyes prominent. Rostrum quadrate, distinctly longer than broad, sides subparallel; genae not dilated, bluntly rectangular at apex, similar in the two sexes ; upper surface impressed, tricarinate, the three carina? parallel, the central one lower than the others, the punctuation shallow and indefinite; colour black or piceous with a few short pale seta? |
