tlian broad, 5-7 shorter and inoniliform ; club elongate-oval, indistinctly 

 quadriarticulate. 



Legs moderately elongate^ tibiae slightly mucronate. 



Underside nigrescent, with straw-coloured setae. Prosternum moderately 

 emarginate, coarsely and closely punctate, coxae equidistant from front to 

 rear. Metasternum short, medially depressed. Basal segment truncate 

 and depressed between the widely distant coxae, apparently longer than 

 second, their suture indistinct, third and fourth only moderately abbreviated, 

 together as long as the fifth, which is grooved along the middle.

 shallow punctures, elytra irregularly seriate-punctate, most of the punctures 

 oblong.

Elongate, moderately convex, subopaque ; nigro-fuscous, antennae and 

 tarsi fusco-rufous ; very scantily clothed with short, suberect, obscurely 

 fulvescent setae. 



Eostrum as long as thorax, only slightly arched, parallel, finely punctate 

 and piceo-rufous in fiont of the antennae, relatively coarsely punctured 

 and moderately distinctly tricarinate behind them. Thorax scarcely longer 

 than broad, slightly widened before the middle, gradually narrowed behind, 

 somewhat contracted in front, base and apex truncate ; coarsely and closely 

 punctate, more finely in front, with a mesial depression at its base. 

 Scutellum absent. Elytra almost oblong-oval, double the length of thorax, 

 slightly wider than it is at the base, a little oblique towards the shoulders, 

 a third broader near the middle, gradually narrowed behind ; their coarse 

 subseriate punctation rendered irregular by small rugae or granules, but 

 substriate along the posterior declivity ; third interstices subcarinate, fifth 

 less so, on each elytron there is a basal depression between these, and a 

 scutellar one. 



Scape inserted near the apex, hardly reaching the eye, slightly flexuous, 

 gradually incrassate ; funiculus finely setose, basal joint thicker and rather 

 longer than second, joints 3-7 transverse, gradually expanded ; club ovate, 

 indistinctly articulate, finely pubescent. 



Legs elongate, femora simple, tibiae uncinate, tarsi rather narrow, their 

 penultimate joint excavate above, emarginate at apex but not divided 

 underneath . 



Underside slightly nitid, blackish, coarsely punctate, with a few fulvescent 

 setae. Prosternal depression broad, without hind margins, not extendino- 

 beyond the coxae. Posterior coxae more widely separated than the inter- 

 mediate. Metasternum short. Basal abdominal segment widely truncate 

 between the coxae, second slightly shorter, its frontal suture apparently 

 straight but very fine, third and fourth very short, with deep straight 

 sutures. 



This cannot be placed in Sosgenes (Man. N.Z Coleopt., p. 1476), which 

 has the frontal portion of the rostrum distinctly marked off as in CJypeor- 

 hynchus (Man. N.Z. Coleopt., p. 1210) ; but as it accords better with
