334 Mr. R. I. Pocock on some dric, very densely punctate. Elytra densely and coarsely punctate, along the suture shorter than the thorax, at the sides about as long as the thorax. Hind body slender, elongate and cylindric, almost destitute of pubescence, very coarsely punctate. Male with a rather deep notch on the hind margin of the terminal ventral plate, and with the pre-ceding segment slightly depressed along the middle and pubescent on each side of the depression. Nikko, Tokio, Fukushima ; six specimens. This is allied to S. currax and S. sedatiis, but can be readily distinguished from the latter by the more slender form, intense black colour, and by the almost complete absence of pubescence on the hind body. S. currax has a differently formed head, comparatively obsolete punctuation on the hind body, and a remarkably conspicuous white pubes-cence on the basal segments of that part. Steniis Jlavidulus, n. sp. (Sect. II. B, Erichson.) Elongatus, angustulus, rufo-testaceus ; capite inter oculos, pectore abdominisque apice nigris ; autennis, palpis pedibusque flavis. Long. 5-5 2 millim. Antennge very long. Head black, red in front of the antenna, not excavate but broadly and shallowly bisulcate, rather sparingly punctate. Thorax elongate, subcylindric, rather coarsely but not densely punctate. Elytra as long as the thorax and punctate like it. Hind body slender, elongate, very scantily pubescent, the basal segments sparingly punc-tate, the apical almost impunctate. Male with a large angu-lar notch on the last ventral plate. Honjo, in Tokio, under rushes with Dn/pta fulveola, an insect of somewhat similar colour ; in late autumn and early spring in plenty. This species is very distinct on account of its colour. The only species I am acquainted with that are like it in this respect inhabit Ceylon. [To be continued.] XXXVin. — Notes on some Buthida?, new and old. By R. I.
