Show 1893.] BEETLES OF THE FAMILY CLER1D.E. 577 ORTHRIUS, Gorham (Cist. Ent. 1876, p. 74). Orthrius was proposed by me for an Australian species (0. cylindricus), a smooth cylindrical insect with only the labial palpi hatchet-shaped at the tip, and the eyes coarse, scarcely cut out. I have since then recognized that many Eastern species placed in various genera should be united with it, though not often so cylindrical. Clerus subfasciatus, Westwood, Thanasimus sellalus, Westwood, Opilo sinensis, Gorh., and probably some others cannot be retained in those genera, but will form a homogeneous group under this name. ORTHRIUS BRACHIALIS, n. sp. 0. tarsali, Gorh., affinis et summa similitudine, ferrugineus, nitidus, tibiis geniculisque nigris, elgtris substriatis perobsolete punctatis. Long. 10 millim. Hab. Assam, Sudiya, Naga Hills, Patkai Mountains (Bohertg). Very closely allied to 0. tarsalis, described by m e in the ' Annals ' of the Genoa Museum of Natural History for 1892, a species from Burmah, and only differing from it in having merely the tips of the femora and the tibiae black, whereas in 0. tarsalis the femora and breast are also black. The striation and punctuation of the elytra are a little more distinct. The specimen from the Nagas has the antennae a little more infuscate, and in both it and the other specimens the tarsi have their uppersides dark. A single example from Patkai is not well developed and has the tibias red, being, in fact, ferruginous all over, but does not, I think, represent another species. The femora in this species and its allies are subincrassate, especially the front pair. THANASIMUS CARBONARIUS, n. sp. Ater ; antennarum articulo ultimo, femorumque basi albo-testaceis, pirothorace tuberculoso-incequali, elgtris basi granidatis nonnullis seriatim instruciis, dimidio apicali sublcevi, versus apicem fascia argenteo-pubescente ad suturam interrupta. Long. 8 millim. Hab. Manipur (Bohertg). Coal-black, a little shining; eyes finely granulated, deeply and angularly excised; antennas longer than the head and thorax, dull and pubescent, compressed, the three basal joints pitchy, the apical joint acuminate, nearly white, and the one preceding pale, the second joint very short, the third as long as the two basal joints, those following gradually increasing in width, not serrate. The thorax longer than wide, very rugose and uneven, having several tubercles, one of which before the middle of the base is round and shining. Elytra not much wider than the thorax, their basal third very rough, with two rows of elongate sharp tubercles on each, very irregular and often coalescing, the apex smooth, with an oblique fascia-like band of silvery hairs at about a quarter from the apex; a few scattered hairs are found all over the elytra, |
