OF NE^Y ZEALAND. 1495 



with strongly-developed apical hooks, those of the anterior very 

 prominent, proceeding from the outer angle and directed forwards, 

 so that they are not greatly curved ; the inner apex is a little 

 prominent, with a slender spine ; there is another spinule on the 

 inner face, near the middle, between this and the extremity the 

 tibim are distinctly ciliate ; the other pairs with strongly-protruding 

 spurs, and a slender process at the inner angle. Tarsi narrow, not 

 long ; first joint longest, slender at the base, second and third equal ; 

 third entire, or nearly so; apical joint, at its base, minutely articu- 

 late, inserted into the apex of the penultimate. Claws very minute, 

 hardly distinguishable. Prostcrnum incurved in front, with a narrow 

 process which reaches the middle of the coxce ; these are prominent 

 and nearly contiguous. Metastcrnum short, depressed. Middle 

 coxoi evidently less separated than the posterior. Abdomen elongate, 

 its two basal segments about equal, with a fine sinuous suture 

 between them ; third and fourth with very broad, deep, straight 

 sutures, which, however, become much finer at the sides. 



The eyes are minute, free, depressed, lateral, rotundatc, and 

 coarsely facetted. The scutellum is obsolete, or altogether absent. 

 These characters, in conjunction with the minute claws, &c., differen- 

 tiate this from the numerous genera in Sect. V. of Wollaston's 

 " Genera of the Cossonida." 



2577. A. urquharti, ii.s. Shining, pitchy-red, legs paler, 

 tarsi yellowish-red ; convex, elongate-ovate. 



Eostrum very finely and distantly punctate, a little widened near 

 the middle, nearly the length of the thorax, its base on a slightly 

 higher level than the front of the head. Thorax a little wider near 

 the middle than it is elsewhere, more narrowed in front than behind ; 

 with rather distant but distinct punctures, each wdth a very minute 

 yellowish seta, near each side of the base there is a fine fringe, the 

 apical punctures are small. Elytra widest near the middle, much 

 narrowed posteriorly ; each with discoidal series of rather coarse, 

 but not closely-placed, punctures, the sutural usually closer than 

 those of the second or third, the posterior sculpture finer and sub- 

 striate ; each puncture has a very minute seta, there are also a few 

 scattered, greyish, slender, indistinct hairs ; interstices distantly and 

 minutely punctured. 



Underside shining, more or less coarsely but not closely punctured, 

 the second ventral segment much more finely and sparingly than the 

 first, with slender yellow setaB ; abroad impression extends from the 

 middle coxas to the hind margin of the first segment. Femora simi- 

 larly, rather coarsely, sculptured and clothed. 



Antenna : Scape nude ; funiculus with yellowish hairs, which, on 

 approaching the club, become more conspicuous, sometimes there is 

 a coarse, curved bristle attached to the seventh joint. 



Var. A. Elytra substriate at base. Thoracic basal cilia) wanting. 

 There is a very minute scutellum (one example). 



Length (rost. inch), 1^ lines; breadth, f line. 



Mount Pirongia. Four, specimens, amongst decaying leaves.
