Hah. Sierra Leone. M y collection. Of this species I possess three specimens ; they are rather larger than the preceding species, and of the same coloration, but the head is longer and the structure of the frontal elevations and carina totally different; the thorax is also much more transverse and has the sides strongly rounded; tbe legs are less robust and more slender. MALAXIA MARSHALLI, n. sp. Black, the head and thorax fulvous, pubescent, the former with one, the latter with three fuscous spots ; elytra bright green, finely rugose and pubescent; legs pale fulvous. Length 3 lines. Elongate and parallel; the head rugosely punctured, pale fulvous, the middle of the vertex occupied by a broad fuscous band; clypeus strongly raised in shape of a transverse ridge, flavous ; antennae extending beyond the middle of the elytra, black, the lower three joints and the base of the three or four following joints pale fulvous, third joint much shorter than the fourth, double as long as the second; thorax twice as broad as long, the sides strongly rounded at the middle, narrowed at the base, the anterior angles in shape of a small tubercle, posterior angles placed in front of the basal margin, the latter straight, the anterior margin concave, the surface transversely sulcate, finely rugose and pubescent, pale fulvous, the middle with a smaller, the sides with a larger fuscous spot, somewhat the shape of a band and narrowed posteriorly; scutellum black, strongly pubescent; elytra finely rugose and wrinkled, bright metallic green, clothed with greyish pubescence: underside piceous or black, the last abdominal segment obscure fulvous ; legs entirely of that colour, the last joint of the tarsi fuscous. Hab. Mashonaland (67. Marshall). Coll. British Museum and my own. Closely allied to M. alluaudl, Alld., but in that species, of which I possess a typical specimen, the entire upper portion of the head is fuscous, and the thorax is not transversely sulcate, but has some depressions anteriorly and at the middle, and in the specimen before me, named by Allard, there are also twTo lateral spots at the sides of the thorax instead of one. |
