Head moderately transverse, convex, with sparse grey scaling which is denser round the eyes ; forehead very finely striolate and without impressions; eyes convex but not prominent. Rostrum as long as broad, basal margin subtruncate, sides subparallel, gena? not dilated ; upper surface plane, finely rugose and squamose, narrowly tricarinate, the outer carina? with a slight outward curve in the apical half. Antennce rather long and slender, piceous, with fine grey pubescence; scape narrow, cylindrical, evenly curved and gradually thickened to apex; funicle with the first and third joints equal. Prothorax strongly transverse, subcylindrical, truncate at base and apex, the latter scarcely narrower than the former, sides slightly rounded, broadest about middle ; upper surface convex, finely coriaceous, and without lateral impressions, but with a shallow transverse impressed line close to apex; colour black, with grey scaling having a metallic greenish reflection. Ely tret short, broadly ovate, truncate at base, sides strongly rounded, broadest before middle ; upper surface convex, with fine stria? containing rows of shallow punctures; the intervals rather broad, of equal width, almost plane, finely alutaceous and entirely devoid of granules ; colour black, with scattered traces of metallic green scaling. Legs moderate, piceous brown, with fine grey scaling and seta?; anterior tibia? quite straight externally and scarcely curved internally. T Y P E 2 in the South African Museum.

The species is closely related to S. viridis, but differs in its undilated gena?, more slender scape, and much shorter rotund elytra. 35. SCIOBIUS FRASINUS, sp. nov. (Plate XIX. fig. 5.) Long. 4-4|, lat. 14-2 m m. Colour black, densely and uniformly covered throughout with greyish-green or bluish-green scaling. Head transverse, slightly convex, coriaceous; forehead without ;iny impressions ; eyes rather prominent. Rostrum a little longer than broad, its basal margin sharply angulate, sides straight and parallel, genae not at all dilated in either sex; upper surface plane and almost smooth, with only a faint central carina; the outer carina? obsolescent and quite hidden beneath the dense scaling. Antennce long and slender ; scape not compressed, sub-cylindrical, slender, gently curved and abruptly clavate; funicle with the first and third joints subequal. Prothorax distinctly transverse, subcylindrical, base and apex of equal width and both truncate, sides very slightly rounded, broadest at middle ; upper surface convex, evenly coriaceous throughout and without any |
