MARSHALL ON THE [Mar. 20, sickle-shaped processes ; in the 2 the sic^es are subparallel basally and the gena? are only moderately and roundly dilated ; upper surface impressed, tricarinate, the outer carina? parallel from base to beyond middle, thence widely diverging, an additional short curved carina in front of eyes ; punctuation and scaling as on the head, the central carina bare. Antennce comparatively long and slender, piceous, with fine grey pubescence ; scape clavate, slightly compressed and distinctly curved; first joint of funicle about as long as third, the subterminal joints elongate. Prothorax moderately transverse, base gently bisinuate, sides not much rounded, broadest before middle, with a shallow constriction near apex, which is truncate and narrower than the base; upper surface convex, with scattered rounded granules, except along a broad central space which is almost smooth, punctured and slightly elevated, being more prominent in the 2 than in the <$ ; a rounded impression on each side near base; colour piceous, the granules and the central ridge (in the 2 ) bare, the interstices with grey scaling. Elytra subtruncate at base, ovate, more acuminate apically in the <$ , so that the sides appear more rounded than in the 2 > broadest well before middle; upper surface convex, with broad stria? containing shallow rugose punctuation, the intervals convex, more or less distinctly granulate, often subrugose ; colour piceous, with uniform grey scaling, the intervals posteriorly with rows of small grey squamiform seta?. Legs piceous or ferrugineous, with the knees black, and with fine grey scaling ; all the femora more strongly clavate in the <S than in the 2 > a R d the tibia? more strongly curved, especially the anterior pairs.

Allied to granosus Fahr., but with much narrower elytra, the obliquity of the shoulders being most noticeable in the <3 ; the sides of the prothorax are also much less strongly rounded and the lateral impressions deeper; in perfect specimens there is a small round whitish spot at the base of each elytron. 3. SCIOBIUS CINEREUS, sp. nov. (Plate XVIII. fig. 3.) Long. 9f-10|, lat. 5-6 m m. Head transverse, with coarse shallow punctuation which is hidden by dense grey scaling ; forehead with a central impression and with a slightly raised fold above the eyes, which are prominent. Rostrum rather longer than broad, sides parallel to beyond middle; gena? sharply and laterally produced in both sexes, but more prominent in the o* ; upper surface shallowly impressed, tricarinate, the outer carina? with a strong outward curve towards apex ; punctuation rugose, but the whole surface covered with dense scaling except the central carina. Antennce moderately long and thick, piceous, with dense grey pubescence ; scape sub-cylindrical, evenly curved and gradually clavate; funicle with the first joint equal to the third, the subterminal joints comparatively |
