Show 546 MR. M. JA.COBV ON THE [May 18, PSEUDIVONGIUS, n. gen. Body ovate, non-pubescent; antennae filiform, the apical joints thickened ; eyes notched; epistome not separated from the face ; thorax transversely subcylindrical; elytra punctate-striate ; femora fusiform, unarmed, the posterior four tibiae emarginate at the apex, non-sulcate ; claws bifid, the inner division very short; prosternum broad, one-half longer than broad; the anterior margin of the thoracic episternum strongly convex. I am obliged to separate this genus from all others belonging to the group of Typophorince on account of the wTant of an ocular sulcus, the non-separation of the clypeus from the face, and the unarmed femora; the shape of the thorax agrees partly with Syagrus, but there is no trace of any tooth at the femora; in the general ovate and posteriorly pointed shape the species differs also from most of its African congeners of this group. PSEUDIVONGIUS NATALENSIS, n. sp. Oblong-ovate, dark aeneous, the basal joints of the antennae and the tarsi and tibiae fulvous ; thorax finely and closely punctured, elytra strongly punctate-striate, the shoulders with two short oblique costae. Length f-1 line. Head finely and somewhat rugosely punctured, the clypeus not separated from the face, its anterior margin concave, eyes distinctly notched, labrum piceous ; antennae filiform, the apical five joints thickened, black, the lower four joints fulvous ; thorax transverse, subcylindrical, the sides strongly deflexed, the lateral margin nearly straight, the surface finely and rather closely punctured, the space near the lateral margins nearly impunctate: scutellum triangular, impunctate ; elytra widened at the middle, pointed posteriorly, dark aeneous, strongly punctate-striate, the interstices slightly convex and impunctate, those at the shoulders forming two short oblique, more or less distinct costae, the punctures at the same place abbreviated or joined at the ends ; the suture in the female deeply depressed at the posterior portion, forming a longitudinal sulcation ; underside nearly black, with greenish gloss at the breast; legs fulvous, the femora metallic greenish at the middle portion ; prosternum strongly rugose. Hab. Natal, Estcourt (67. Marshall). This small species will not be difficult to recognize on account of the ovate shape, the short elytral humeral costae, and the peculiar sutural depression in the female, of which I know no simdar instance amongst the numerous other African genera of Eumolpidaa. PSEUDOMALEGIA, n. gen. Body oblong, pubescent above and below; eyes entire; antenna? filiform, the last five joints thickened; thorax subcylindrical, rather flattened, without distinct lateral margin; femora unarmed: tibiae not emarginate at apex; claws bifid; prosternum |
