OF NEW ZEALAND. 1217 



narrow, free, very little convex. Thorax longer than broad, broadest 

 near the front, uneven, nearly straight -sided behind ; with a short 

 longitudinal elevation on the middle near the apex, two tubercles on 

 the middle having indistinct elevations proceeding backwards, the 

 base between them appearing depressed, there is another elongate 

 elevation near each side before the middle, the sides too are uneven, 

 there are no punctures. Scutellum small. Elytra very elongate- 

 oval and convex, narrowed at base to width of thorax, sides vertical, 

 apex sloping; they have rows of coarse punctiform impressions, a 

 broad curved groove near each shoulder, the third, fifth, sixth, and 

 seventh interstices are more or less irregularly raised, third nodose 

 behind, fifth ending with a smaller nodosity placed further back, 

 nearly similar sculpture extends down the hind slope. Legs long ; 

 femora notched at apex, clavate ; tibiae flexuous, mucronate. 



Underside clothed and coloured like the upper surface, almost 

 impunctate. Prosternum deeply emarginated ; ocular lobes distinct ; 

 no scar on the mandibles : posterior tibice a little expanded at apex, 

 without cavernous corbels ; tarsi with dense brush-like soles, basal 

 joint nude, or nearly so, at base, lobes of the third narrow. 



Length (rost. incl.), 7|; breadth, 2f lines. 



Mount Egmont. I owe my specimen to the kindness of Mr. 

 A. T. Urquhart. 



OBS. Pheeophanus, Heteraomus, Phoxoteles, and Anagotus are 

 nearly- allied forms. 



Heteraomus. 



Nov. gen. 



Rostrum moderately elongate, dilated at apex (pterygiate), other- 

 wise parallel-sided, apex deflexed. Scrobes deep, visible above in 

 front, directed towards the underside but not reaching the eyes. 

 Antennce elongate, scape attaining the eye, thickened at the ex- 

 tremity; squamose ; funiculus 7-articulate, two basal joints elon- 

 gate, second rather longer than first ; club elongate-oval. Eyes free, 

 oviform, yet almost truncate in front, transverse, rather large, not 

 widely separated above. Thorax subcylindric, widest near the 

 front, widely incurved above the eyes and obtusely rounded below 

 so that the ocular lobes are moderately developed. Scutellum small. 

 Elytra oblong-oval, truncate at base and closely adapted to thorax, 

 scarcely exceeding it in breadth, apex sloping, not suddenly deflexed. 

 Prosternum emarginate, anterior coxae prominent and contiguous, 

 separated in front only by the short sternal process ; mesosternum 

 moderate, its rather broad process extending backwards half-way 

 between the middle coxae so as to overlap the anterior projection of 

 the metasternum, which is short ; posterior -coxa widely separated. 

 Abdomen cuneiform, its two basal segments large, each about as long 

 as the metasternum, their suture sinuous, next two short with deep, 

 straight sutures, the apical equalling the basal in length. Epipleurce 

 extremely narrow; pseudepipleurae vertical. Legs long, tibiae 

 flexuous, unarmed at apex, corbels not cavernous ; tarsi elongate,
