172 Mr. G. R. Waterliouse's Descriptions of XXI. Descriptions of New Genera and Species of Cur-culionides. By G. R. Waterhouse, Esq., F. Z. S. [Read 7th February, 1853.] Oxyrhjjnchus FortiDiei. Oblongo-ovatus, piilvere cervino tectiis ; thorace remote punc-tato, albo-tri-liiieato; elytris seriatim ocellato-punctatis, in-terstitiis alternis elevatis, singulis linea alba ab humero ad medium suturae ducta, notatis. Long. Corp., rostro excluso, lin. 7; latitudo lin. 2| : $, long. 5| ; lat. 24. Patria, China Boreali. Considerably larger, and proportionately broader, tban 0. discors; the dilated basal j)ortion of the rostrum broader and sliorter ; the puncturing both on thorax and elytra less distinct, the punctures being smaller and more remote; the interstices of the striaj of the elytra broader, and the alternate interstices very distinctly raised, and subcarinated. The ridges formed by the fourth and sixth interstices are united at some distance from the apex of the elytra; the suture, on the hinder half, is also raised, and from the apex there is a short ridge which runs obliquely forwards and slightly outwards to meet the second interstitial ridge. A series of very minute tubercles, each bearing a single pointed scale at its sum-mit, is seen on each of the ridges mentioned. The general colour is sometimes ashy, sometimes very pale rufous brown. The middle pale band on the thorax does not extend quite to the base. On the forehead is a small fovea, and on the basal portion of the rostrum is a longitudinally-impressed line ; in front of this the rostrum is keeled ; in the female the keel is very short, but in the male it reaches about half way to the apex of tiie rostrum : here the rostrum is rather shorter than in the female, and strongly punctured ; the scales extend beyond the point of in-sertion of the antenna, whilst in the female scales extend only to the points mentioned, and the fore part of the rostrum is nearly smooth. Several specimens of this insect were brought from North China by Mr. Fortune, so well known for his travels and re-searches in that quarter of the globe. It is after this gentleman that I have named the insect.
