Legs somewhat asperate and finely setose. The rostrum, underneath, tri- 

 carinate in front, smooth behind. 



Female. — Rostrum much arched above, longer than the thorax, more 

 slender than that of the male, a little asperate and coarsely rugosely punctured 

 at the base, the punctuation more distinct, finer, and subseriate towards 

 the front, and bearing some short setre along its sides behind the antennae, 

 which are inserted just before the middle. 



Var. S ■ — The coarse lateral seta? of the rostrum near the front obsolete 

 or absent. 



S . Length, 2J lines ; breadth, f line. 



Parua and Hunua Range. Both sexes. 



Pogonorhinus, Brouli. Man. N.Z. Coleopt., p. 532. 



Depressed, moderately broad, subfusiform, opaque, bearing semi-erect 

 slender yellow set?e. 



Rostrum about as long as the thorax, slightly arched, cylindrical, not 

 quite half the breadth of the head, and marked of? at the base by a transverse 

 linear impression ; at each side, from the extremity to behind the middle, 

 it is fringed rather thickly with long conspicuous bright - yellow setse ; 

 this fringe is prolonged underneath and becomes finer, and approximated 

 to its fellow, near the eye. Scrobes profound, beginning near the apex and 

 extending to the eyes, linear. Head rounded in front, immersed to the 

 eyes, globose underneath. Eyes not prominent, large, their greatest bulk 

 below, and so situated that vision must be directed nearly straight forwards. 

 Scape inserted between the apex and the middle, moderately stout, nearly 

 straight, gradually incrassate, not quite attaining the eye. Funiculus 

 closely articulated, 2nd joint nearly as long as the 1st, both nearly twice 

 as long as they are broad, 3-7 gradually thickened, transverse, 7th largest. 

 Club elongate, oviform, subacuminate, but little broader at its base than 

 the 7th joint, almost quadriarticulate. Thorax as broad as it is long, sub- 

 conical, abruptly contracted in front, base subtruncate, the sides well 

 rounded. Scutellum distinct. Elytra gradually narrowed backwards, the 

 base slightly bisinuate and rather wider than that of the thorax. Femora 

 moderately elongate, strongly arched above, widely notched near the 

 extremity, angulate and distinctly dentate medially below : those of the 

 female nearly similar. Tibi* moderately uncinate, the 2 hind pairs dilated 

 inwardly below the middle, the front pair prominent and finely ciliate at the 

 middle, but emarginated between the middle and extremity in both sexes. 

 Tarsi relatively slender, basal joint shorter than the terminal, the 3rd 

 slightly dilated, deeply excavate above and appearing lobate, but under- 

 neath apparently entire. 



Female. — Rostrum arched, more slender, not ciliate. Scape inserted 

 before the middle. 



Underside nearly plane, minutely setose, moderately coarsely punctate. 

 Prosternum deeply incurved medially in front, the coxse slightly separated, 

 more approximated than in Phloeophagosoma, and with much larger cavities, 

 and more nearly contiguous than those of Arecophaga. Mesosternal suture 

 truncate, and very distinct between the coxte. 



This genus most nearly resembles Arecophaga, but is differentiated by 

 the more approximated anterior coxa3, shorter and rather stouter rostrum, 

 dentate femora, &c. Out of 122 genera enumerated in Wollaston's " Genera 

 of the Cossonidee " four only approach this one in structure. Odontomesites,
