Osphryon forbesi (Gahan, 1894)
Described: On the Characters of a new Genus and Six new Species of Longicorn Coleoptera from New Guinea.
The Annals and Magazine of Natural History, London 13 (6) 75: 288-293.
Description: Dark brown, almost entirely dull and opaque above. The head with a sparse fulvous pubescence. The prothorax is fringed anteriorly and at the base with fulvous hairs ; the two anterior spines at each side are connate at their base, and so likewise are the two posterior spines; the disk bears two feebly raised humps which are strongly and closely punctured. The elytra are devoid of pubescence, but under the lens are seen to bear numerous minute granules which seem to correspond to the setigerous punctures of O. adustus, Pasc. The underside of the thorax has a fulvous pubescence. The abdomen is glossy, sparsely punctured and almost impubescent; the fifth ventral segment of the male is feebly emarginate (almost truncate) behind. The antennae are slightly longer than the body; the first two joints and the base of the third are thickly and strongly punctured; the third (except at the base) and the remaining joints are very minutely and closely punctulate and opaque; some feeble or obsoletely raised lines are to be seen on nearly all these joints ; each joint from the third to the tenth is acutely angular or toothed on the outer side at the apex, and is produced into a distinct dentate or spinous process on the inner side. These cha-racters of the antennae would almost justify the separation of this species into a distinct genus; but in other respects it agrees very well with the remaining two species of Osphryon.
