Show 250 MR. G. A. K. MARSHALL ON THE [Mar. 20. tricarinate, the central carina sometimes obsolescent, the outer ones straight and parallel. Antennce long and slender, piceous. with fine grey scaling; the scape compressed, strongly bisinuate, gradually dilated to apex; funicle with the third joint distinctly longer than first, the subterminal ones elongate and clavate. Prothorax twice as broad as long in the <$, more than twice as broad in the 2 > ^ a s e subangulate, apex narrower and sinuate (more markedly so in the 6 ), sides slightly rounded, broadest at base; upper surface slightly convex, closely set with low rounded granules, with a smooth subdepressed central line and a distinct curved impression on each side; colour black, granules bare, the interstices with fine grey or yellowish scaling, which is sparse on the disk, except in the three impressed lines, and very dense on the underparts. Elytra narrowly ovate in the 6 , broadly ovate in the 2 •> jointly emarginate at base, the humeral angle more, or less acutely prominent in <5 , obtuse in 2 '•> sides almost parallel from base to beyond middle in o*, strongly rounded and broadest about middle in 2 j upper surface depressed in <$, convex in 2 J with broad stria? containing rows of shallow punctures separated by small granules ; the intervals convex, with irregular obsolescent granules, which are distinct and prominent only on the apical declivity, the second interval broader than the third near the base in the 2 o n ry '•> colour black, with grey or yellowish scaling, which is sparse dorsally, but forms a dense irregular band along the inflexed margins and across the summit of the declivity; on the disk there are some stripes of denser scaling in the S . Legs long and thick in cS> short and comparatively slender in 2 » piceous, with even fine grey scaling ; in the tf the posterior pairs of tibia? are slightly curved, the anterior pair very strongly so, the posterior femora reach, when fully extended, just beyond the elytra ; in the 2 the anterior tibia? are only slightly curved and the posterior pairs straight, the posterior femora do not reach the apex of the elytra. T Y P E J in the Stockholm Museum. N A T A L : Durban (J. P. Cregoe & A. D. Millar), Malvern (C. X. Barker & G. A. K. M.), Upper Tongaat R. (C. X. Barker), Lower Tugela R. (E. D. Reynolds). Z U L U L A N D : Lower Tugela R. (E. D. Reynolds), Eshowe (A. Windham), TRANSVAAL: Potchefstroom (T. Ayres). In the British Museum there is a series of 8 males and 3 females from the Lower Tugela, which represent a fairly well-marked varietal form. The difference is more marked in the <$ , in which the elytra are distinctly broader in proportion to their length, the sides being gently rounded instead of subparallel; the humeral angle is therefore more obtuse and the intervals appear to be a little broader. The markings on the elytra are pure white, there being a sharply defined stripe on the second interval which unites near the base with a quadrate scutellar patch. The 2 differs only in shape from the type form, two of the specimens having the elytra much shorter and more rotund; the third example, |
