118 SUBANTARCTIC ISLANDS OF NEW ZEALAND, [Colcoptera. 



Stilbodiscus setarius, sp. no v. (Plate V, fig. 6.) 



Elongate, slightly convex, moderately nitid, castaneo-rufous, tarsi paler ; 

 sparingly clothed with short slender depressed, and erect elongate yellowish setae. 



Rostrum almost tricarinate, smooth near the apex. Head almost as wide as 

 front of thorax, narrowed anteriorly, irregularly sculptured, some of the punctures 

 being relatively coarse, the others fine. Thorax widest before the middle, slightly 

 constricted near the apex, very gradually narrowed behind the middle ; the disc 

 broadly bi-impressed longitudinally, its punctuation moderately coarse but not close, 

 and rather shallow ; its base is truncate. Elytra elongate, not closely adapted to 

 the thorax, much narrowed posteriorly, shoulders obtuse ; each elytron with 6 series 

 of moderate punctures, the sutural 2 form striae which are deepest near the base ; 

 interstices rather broad, minutely sculptured, and slightly rugose. 



Underside moderately shining, rufo-castaneous, sparingly punctured, and bear- 

 ing some yellowish setae. Ventral segments with well-marked sutures. 



^ . Length (rost. incl.), 3 J lines ; breadth, 1| lines. 



Campbell Island. 



One specimen, from the recent collection made by Messrs. W. K. Chambers 

 and F. S. Des Barres, of Gisborne. 



Group ERIRHINIDAE. 



Erirhinus, Schoenherr. 



Antennae inserted near the middle of the rostrum, more or less elongate, slender. 

 Scape thickened gradually ; 1st and 2nd joints of the funiculus elongate, the former 

 the larger, joints 3-7 shorter, obconical. Club articulate, oblong-oval. Rostrum 

 more or less elongated, cylindrical, slender, arched ; its scrobes beginning between 

 the middle and extremity, almost rectilinear, and attaining the eyes. Eyes briefly 

 oval, transversal. Thorax transverse, usually a little convex, more or less rounded 

 laterally, truncate at base and apex, with feeble ocular lobes. Scutellum punctiform 

 or triangular, small. Elytra oblong or oblong-oval, narrowed behind, a little wider 

 than the thorax, slightly emarginate at the base. Legs of at least moderate length. 

 Femora clavate, often almost pedunculate at base, unarmed. Tibiae slender, more 

 or less flexuous, mucronate at extremity. Tarsi rather long, narrow, spongy under- 

 neath, 3rd joint distinctly broader than 1st or 2nd, 4th moderate, likewise the claws. 

 2nd abdominal segment as long as 3rd and 4th taken together, separated from the 

 1st by a nearly straight suture. Intercoxal process rather wide, rounded or angulated 

 in front. Metasternum more or less elongate. Body oblong or oval, generally densely 

 pubescent. 



Dorytomus, Germar, is considered synonymous by many European entomo- 

 logists ; it is without ocular lobes, but the femora are dentate below. 



Erirhinus dracophyllae, sp. nov. (Plate III, fig. 6.) 



Elongate, subovate, slightly nitid, fulvescent, elytra testaceous ; pubescence 

 scanty, greyish, slender, and inconspicuous. 



Rostrum arched, slender, very elongate, about as long as the elytra ; longi- 

 tudinally grooved, with a series of punctures across the extremity. Mandibles 

 prominent, bifid at apex. Head rotundate, globose underneath. Eyes subrotundate,
