The minute size of the body, long arched rostrum, abbreviated meta- 

 sternum, enormously expanded intermediate tarsal joints, apparently un- 

 armed tibifie, and obsolete scutellum, independently of other characters, 

 remove this from all the genera known to me. The species live on Phormmm 

 tenax. 



No vitas rufum, Broun. 938. Man. N.Z. Coleopt., p. 528. 



Rufous, only slightly nitid, rostrum and thorax subopacjue, antennse 

 and tarsi pale red. 



Rostrum closely and minutely asperate, distinctly thicker at the base 

 than in the following species, and with less slender antennae. Thorax 

 densely and minutely sculptured ; distinctly, moderately finely, but not 

 closely punctured. Elytra moderately finely punctate-striate, the outer 

 striae indistinct, all more or less effaced at the extremity, apices very slightly 

 dehiscent, the interstices with minute sculpture like that of the thorax.

Parua. Unique. 



N. nigrans, Broun. 939. Man. N.Z. Coleopt., p. 528. 



Subopaque, piceo-niger, apical half of rostrum piceo-rufous, tibiae, 

 tarsi, and antennae ferruginuous. 



Rostrum closely and minutely asperate, but nearly smooth in front. 

 Thorax rather longer than that of 938, more cylindrical, yet oviform ; the 

 derm similarly densely minutely sculptured ; its punctures fewer, coarser, 

 and quite distinct. Elytra rather coarsely striate-punctate near the base, 

 almost obliterated behind the middle, with a sutural stria on each extending 

 to the summit of the posterior declivity ; -the apical sculpture indistinct. 



It is from this species that the generic characters were derived.

Parua (one) ; afterwards both sexes on the Hunua Range. 



N. dispar, Broun. 2204. Man. N.Z. Coleopt., p. 1251. (Plate XVI, fig. 4,) 



Fusco-niger or piceous ; apex of thorax and elytra and terminal 3 ventral 

 segments somewhat castaneous ; rostrum shining, slender, and rufescent. 



Thorax with a sort of silky opacity, unusually broad in front, without 

 perceptible punctures but appearing as if densely minutely granulate, it 

 bears some slender brassy hairs ; in the female it is of the normal shape, 

 narrowed in front. Elytra slightly nitid, striate-punctate as far as the 

 middle. 



Female. — Antennae inserted behind the middle.

Tiritiri Island. Four specimens. 



Unas, gen. nov. 



Body subcylindric, transversely convex, apparently nude, with minute 

 almost invisible pubescence only ; shining, nigrescent, coarsely sculptured. 



Rostrum arched, broad, subparallel, only very slightly narrowed towards 

 the extremity, rather shorter than the thorax, not marked off from the 

 forehead. Scrobes oblique. Head globose, its sides slightly narrowed 

 behind the eyes. Scape medially inserted, very short and stout, still 

 thicker at the extremity. Funiculus compact, basal joint moderately large, 

 joints 2-5 transverse. Club but little broader than the 5th joint of the 

 funiculus, oblong-oval, annnlate. Eyes prominent, small, rotundate, less
