MARSHALL ON THE [Mar. 20, at base and very slightly narrowed from there to the apical constriction ; in $ a little more transverse, sides slightly rounded and the apical constriction less evident; upper surface subdepressed, granulation very variable, usually depressed and subcontinent, occasionally subobsolescent, sometimes with a faint, rounded, very shallow impression on each side not far from base ; colour piceous, with fine grey pubescence, denser laterally and there bearing a bright yellow powdering, which, however, is easily abraded. Elytra in J very narrowly ovate, truncate or slightly emarginate at base, constricted behind the shoulders, which have an acute tubercular prominence; sides moderately rounded, broadest about middle, rounded apically ; in $ broadly ovate, slightly sinuate at base, shoulders normal and not prominent, sides more strongly rounded, subacuminate apically; upper surface slightly convex or subdepressed, steeply declivous and distinctly retuse posteriorly, especially in 2 •> with distinct stria? containing shallow punctures separated by small granules, the intervals almost plane, coriaceous and devoid of granules; colour piceous or cas-taneous, with very fine thin grey pubescence, the inflexed margins with a broad stripe of denser pubescence having a bright yellow powdering; there is also a similar but narrower sutural stripe extending from base to near apex. Legs slender and elongate, piceous, or ferruginous with the knees and coxa? darker, with fine grey pubescence; anterior tibia? straight externally in both sexes. T Y P E S in the Stockholm Museum. NATAL : Malvern (C. X. Barker), Howick (Dr. F. Dimock Brown). Apart from the type I have seen only a single tf and 2 > which I refer provisionally to this species. The former, however, differs from the type in having the shoulders merely subrectangular and without any distinct tubercular prominence, the constriction of the prothorax being less marked and the sutural stripe wanting. But without more material it is difficult to say whether these are specific or merely varietal characters. 24. SCIOBIUS SPATULATUS, sp. nov. (Plate XVIII. fig. 10.) Long. 6f, lat. 3-| m m . Head very short, strongly transverse, slightly convex, aciculate and with sparse yellowish pubescence forming a denser ring round the eyes, which are not prominent, forehead with a shallow central impression. Rostrum longer than broad, arcuate at base, sides sinuate, gena? rounded and scarcely dilated; upper surface shallowly impressed, tricarinate, the outer carina? curved and higher than the central one, aciculate and with pale setiform scaling which is denser beneath. Antennce piceous, with fine grey pubescence; scape compressed, broadly dilated, subfusiform, with a distinct central carina above and bisulcate beneath ; funicle long and s'ender, the third joint much longer than the first, the subterminal joints elongate, subcorneal. Prothorax subcylindrical, as long as its width at apex, which is truncate, base a little |
