Show 1893.] BEETLES O F T H E F A M I L Y CLERID.E. 575 usual lateral white scales. The wide head, lobed sides of the thorax, and form of the elytra, depressed at the base and narrowing to their apex, give this species much the appearance of a large Hydnocera. XENORTHRIUS, Gorham (Ann. del Mus. Civ. Gen. xii. p. 733, 1892). Xenorthrius is proposed by me, in m y descriptions of tbe Cleridae collected by L. Fea in Burmah, for a genus of that family of which I have long had a few exponents obtained by Wallace in the East. They are allied to Opilo and to m y genus Orthrius; from the former the conical apical joint of the maxillary palpi, from the latter the eyes distinctly cut out afford sufficient distinction. X. mouhoti, from Laos and Burmah, tbe type of the genus, X. subfasciatus, from Pegu, and X. balteatus, Burmah, described in the publication quoted, have the elytra entire ; I have now to add two species of this section, and one in which the elytra are truncate with a distinct mucro, the genus thus resembling Priocera. XENORTHRIUS EPHIPPIATUS, n. sp. Pallide piceo-brunneus, breviter dense brunneo-pilosus; palpis, pedibus, elytrorum fascia communi undata ad suturam latiore apiceque pallide flavis; prothorace antice et lateraliter punctato, disco postice obsolete, crebre subrugose, elytris lateribus granulose punctatis, fascia et apice sublcevibus. 8-9 millim. Hab. Assam, Patkai Mountains (Doherty). The general colour of this insect is pitchy brown, the elytral fascia and the apex being very pale, almost white, and the brown of the parts margining these is more suffused indeterminately ; the puncturing is similar to that of X. mouhoti, viz. the head is nearly smooth, as well as the front part and rather tumid sides of the thorax ; these parts are separated from tbe disk by the anterior constriction and an impressed line on each side, and tbe disk is thickly, not deeply or strongly, punctured : as this structure seems usual in the genus, it will not be referred to again except where modified in other species. The elytra have also a normal sculpture, viz. striae with rasp-like puncturing, the interstices being flattened in the middle and from thence on each side of the suture to the apex, and the punctures obliterated. The punctures are only distinct in the basal third; they become obsolete and only leave small rasp-like edges behind, and in that part the alternate interstices are raised lines, hardly amounting to costse. Three specimens. XENORTHRIUS GENICULATUS, n. sp. Brunneus ; pedibus pallidioribus, geniculis nigris, tarsis brunneis, capite prothoraceque nitidis, hoc disco crebre obsolclius punctato |
