Head twice as broad as its length, with scattered punctuation and sparse yellow scaling; forehead with an ill-defined central impression and a slight tubercular elevation above the eyes, which are very prominent. Rostrum longer than broad, as long as prothorax, tricarinate dorsally, and with a short lateral carina just in front of eye; genae produced in $ into a long (li mm.) recurved horn-like process, rounded and only slightly prominent in 2 ; upper surface with irregular shallow punctuation and dense ochreous scaling. Antennce moderately long, piceous, irregularly aciculate and with fine pale pubescence ; scape compressed and gently curved, third joint of funicle scarcely longer than first. Prothorax very transverse, sides strongly rounded, especially in the <5, broadest about middle, base truncate, apex narrower and slightly sinuate, with a faint constriction and an impressed transverse line close to the margin ; upper surface convex, but flattened in the median basal area and fairly closely covered with smooth depressed tubercles; the interstices are thinly clothed with ochreous scales, and there is a short curved lateral impression on each side near the base. Elytra broadly ovate, shoulders obliquely rounded, sides ampliated, broadest near base; upper surface convex in 2 •> subdepressed in S > with shallow stria? containing rows of distinct separated granules; the intervals with rows of low rounded tubercles, which are absent on the inflexed margins, the stria? there being also simply punctate ; colour black or piceous brown, granules and tubercles bare and shiny, the interstices with thin yellowish scaling. Legs stout, thicker in the <S , black or piceous brown, finely aciculate and sparsely punctured, with yellowish scales and seta? which are dense near the apex of femora; the anterior pairs of tibia? broader and more strongly curved in the d1.

It is evident from his description that Fahraeus took the <S of this species for the 2 > both sexes being represented in Wahlberg's series. It is curious that he makes no reference to the striking horn-like rostral processes of the o*, which distinguish it from all other species of the genus except S. cultratus. 2. SCIOBIUS CULTRATUS, sp. nov. (Plate XVIII. fig. 1.) Long. 8f-10J, lat. 4|-5f m m. Head strongly transverse, finely aciculate and with rather thin grey scaling ; forehead finely plicate, with no distinct impressions ; eyes prominent. Rostrum distinctly longer than its width at base ; in the o" the sides are somewhat narrowed from the bast to about middle, and the gena? are produced into broad but sharp PROC. ZOOL. Soc-1906, VOL.
