Lyperobius læviusculus, sp. nov.
Pitchy-black, sometimes rufo-piceous; hind-body sparingly clothed with depressed, testaceous, setiform scales. Rostrum nearly plane above, medially narrowed, rather finely punctured. Head broader than the rostrum, with a shallow median groove before the eyes and some transversal linear impressions behind. Eyes more rotundate than those of the typical species. Scrobes deep in front, but quite indefinite behind. Scape thickened apically, attaining the back of the eye. Funiculus sparsely pilose, second joint only slightly shorter than the first; joints 3–7 momliform. Club triarticulate, rather elongate, finely pubescent. Thorax somewhat uneven, without central carina, finely punctate. Elytra oblongoval, humeral angles narrowed and rounded, rather acuminate posteriorly; each elytron indistinctly tricostate, suture slightly elevated, interstices nearly smooth, with only feebly impressed series of punctures. Legs rather elongate; femora clavate; tibiæ flexuous, without the usual inner armature just above the extremity; the anterior pair with pale erect setæ along the inside. Underside nearly smooth, almost nude. Prosternum a little emarginate. Length (rost. included), 10–12 lines; breadth, 3½-5 lines.
Auckland Islands. Captain Bollans, of the Government steamer “Hinemoa,” found two specimens on Adam's Island. The larger one has very indefinite elytral costæ. One specimen retained in Captain Broun's collection, the other placed in the Canterbury Museum.
