Show 258 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, testaceous, third joint very slightly longer than the second, the following more elongate, terminal joint widened at the middle but not longer than the preceding one ; thorax very short, more than twice as broad as long, narrowed anteriorly, the sides straight, the surface rather remotely but distinctly punctured ; scutellum proportionally large ; elytra strongly convex towards tbe apex, strongly punctured in regular and very closely approached rows, distinct to the apex, the interstices slightly longitudinally convex, their epipleurae entirely absent below the middle ; underside piceous ; legs slender, testaceous, the first joint of the posterior tarsi very long. Hab. Kurazol, East Africa. This small species is not difficult to recognize on account of its short thorax and the sculpturing of the elytra, which differs from any species with which I am acquainted. MONOLEPTA NIGROCINCTA, Sp. n. Flavous, antennae fuscous; thorax transverse, impunctate ; elytra finely and closely punctured, very narrowly margined with black ; lateral margins of the thorax obscure piceous. Length 4 millim. Head impunctate, the frontal elevations transverse, the clypeus broad ; labrum black ; antennae extending slightly beyond the middle of the elytra, fuscous, the lower three joints flavous, second and third joints short, equal, the rest elongate; thorax twice as broad as long, the sides feebly rounded, the angles distinct, posterior margin moderately rounded, the surface convex, impunctate, flavous, the lateral margins piceous; scutellum fuscous ; elytra subcylindrical, very finely and closely punctured, the interstices somewhat wrinkled, the extreme margins piceous or black ; elytral epipleurae entirely indistinct below tbe shoulders, margined with black ; below flavous as well as the legs ; the anterior tibiae unarmed, tbe posterior tibiae with a long spine, their metatarsus very long. Hab. Sierra Leone. Similar in colour to Candezea dahlmanni Jac, but the elytral epipleurae indistinct below the shoulders, the antennae and the underside of different coloration, and the general size smaller ; C. tenuicornis Jac. is likewise nearly similarly coloured, but varies also in the same structural differences pointed out, the smaller size, more slender antennae, pale labrum, and the absence of tbe thoracic black lateral margins ; C. nigrosuturalis Jac. has the underside black. MONOLEPTA EXCLAMATIONIS, Sp. U. (Plate XX. fig. 9.) Fulvous, the head and the intermediate joints of the antennae black ; thorax subquadrate, closely punctured; elytra widened posteriorly, punctured like the thorax, the*lateral margins anteriorly, an interrupted longitudinal stripe (widened and abbreviated posteriorly), and a small spot at the apex black. Length 5 millim. Head black, opaque, the frontal elevations broad, trigonate, bounded by a transverse groove behind, clypeus wdth an oblique |
