Show 56 MR. M. JACOBY ON NEW GENERA AND [Jan. 3, Head with a few fine punctures, flavous, a rhomboidal spot at the middle and one on each side at the base black. Antennae black, the second and third joints and the apex of the terminal one fulvous. Thorax nearly three times as broad as long, the sides very moderate y rounded, anterior angles acute; surface finely and not very closely punctured on the disk, much more closely towards the sides ; a broad subquadrate irregular-shaped black spot is situated at each side, and connected anteriorly with a small round spot, another oblong one being placed in the middle of the base. Scutellum black. Elytra extremely closely subrugulose punctate, black, the margins narrowly testaceous, but interrupted at the apex by an elongation of the black portion ; an elongate pear-shaped testaceous spot extends from the middle of the base in an oblique direction to the middle of the elytra. Underside closely pubescent. Four specimens of this well marked species are contained in m y collection. The design of the elytra and thorax will distinguish this insect from any of its allies. GALERUCIDA. LUPERODES, Motsch. 10. LUPERODES MARGINATUS, sp. nov. Oblong, convex, light flavous below. Antenna?, their basal joints excepted, piceous. Above pale olive-green, extreme lateral margins of the elytra and their epipleurae black. Length 3 lines. Hab. Africa, Lagos. Head not longer than broad, with a well marked transverse groove between the eyes, finely punctate, the latter black, prominent. A n tenna? two thirds the length of the body, obscure piceous, the two or three basal joints flavous, joints 2 and 3 very short, of nearly equal length, the rest filiform and slender. Thorax narrowly transverse, its sides straight and narrowed from base to apex, the angles obtuse and rather rounded ; surface like the head, very minutely punctured. Scutellum triangular. Elytra convex, parallel, more distinctly punctured than the thorax, of a very pale greenish tint, with the lateral and apical margins black; this colour is narrowed gradually towards the base, where it is very narrow. Underside and legs flavous, finely pubescent; last abdominal segment in some specimens black. Collection Jacoby. The genus Luperodes, resembling in its general appearance the genus Monolepta, maybe known by the very long first tarsal joint of the posterior legs, the tibiae of which are armed with a long spine, in connexion with the open anterior coxal cavities. 11. LUPERODES AUSTRALIS, sp. nov. Oblong, convex, flavous; apical joints of the antenna?, and the breast, black ; elytra minutely punctured, flavous, the base and a small spot below the middle rufous, |
