Show 256 MR. G. A. K. MARSHALL ON THE [Mar. 20, reaching the base, the outer ones subparallel, finely aciculate and with sparse pale scaling. Antennce slender, piceous, with thin pale pubescence ; scape distinctly bisinuate, compressed and gradually thickened to apex ; third joint of funicle much longer than first, subterminal joints elongate. Prothorax very transverse, the base broadly rounded, sides straight and rapidly converging from base to apex, which is truncate, posterior angles acute ; upper surface rather convex, moderately closely granulate, with a shallow depression on each side near the base ; colour black, granules bare, the interstices with yellowish-white scaling which is denser laterally. Elytra broadly ovate, acuminate posteriorly, jointly sinuate at base and a little broader than the prothorax, shoulders acute, sides strongly rounded, broadest before middle ; upper surface slightly convex, the suture distinctly elevated and the sides strongly inflexed, the stria? deep laterally but shallower on disk, containing rows of shallow punctures separated by minute granules; the intervals finely coriaceous and with a few scattered granules on the declivity; interval 1 elevated, 2 plane, broader than the rest and subdepressed near base, 3 and 4 slightly convex, 5, 6, and 7 narrower and subcarinate, those on the inflexed margin plane ; colour piceous, almost bare, with very fine thin grey scaling. Legs slender, piceous, with fine short white pubescence, the anterior tibia? only slightly curved. T Y P E 2 in the Stockholm Museum. CAFFRARIA (J. Wahlberg). The type is the only example which I have seen of this species. The strong lateral inflection of the elytra, in conjunction with the elevated suture and depressed second interval, gives the insect a very distinctive facies. 17. SCIOBIUS ACICULATIFRONS Boh. S. aciculatifrons Boh. op. cit. vii. 1, p. 198 (1843). Long. 5i-5|, lat. 2f-2i m m. Head moderately transverse, convex, finely and longitudinally plicate, with thin grey scaling; forehead without impressions ; eyes not prominent. Rostrum about as long as broad, sides subparallel to near apex, gena? slightly and roundly dilated ; upper surface plane, rugosely punctured, with three fine carina?, the outer ones straight and parallel. Antennce moderate ; piceous, with fine grey pubescence; scape broad, compressed, strongly curved and gradually dilated to apex; funicle comparatively short, the third joint longer than the first, the outer ones elongate but subcorneal. Prothorax twice as broad as long, arcuate at base, apex truncate and much narrower, sides sub-angulate near base and rapidly narrowed fiom there to apex ; upper surface evenly coriaceous, without any lateral basal impressions ; colour black, with thin grey scaling which is rather denser beneath. Elytra ovate, somewdiat acuminate posteriorly, jointly sinuate at base, sides moderately rounded, broadest before middle ; upper surface not very convex, with fine stria? containing |
