OF NEW ZEALAND. 1077 



equal, basal joint of posterior elongate, fourth minute, the elongate 

 apical one appearing as if articulated above it. 



1165. C. politula. Shining, black, glabrous, the lateral margins 

 and tibiae red, tarsi paler, antennae somewhat variegate, second joint 

 paler than the other dark ones. 



Head moderately distantly punctured. Thorax indistinctly and 

 remotely sculptured. Elytra very convex, their punctuation fine, 

 shallow, and not very evident. 



Underside shining, rufo-piceous, more evidently punctured than 

 the upper surface. 



Length, 1 ; breadth, j line. 



Tairua. Three examples off shrubs. This species was formerly 

 named Cyclomorpha, but, as I find the name had been used before, I 

 have substituted Cyclaxyra. As it is a very interesting genus the 

 new name is accompanied by the description. 



Priasilpha. 



Nov. gen. 



Body subdepressed above, "transversely convex below, oblong-oval, 

 attenuate posteriorly. Head immersed up to eyes, narrowed and 

 prolonged in front of antennae, frontal suture deep and straight. 

 Labrum transverse, entire. Palpi short and stout, their apical joints 

 almost cylindrical, truncate at apex. Mandibles acutely produced 

 at extremity. Eyes large and convex. Antennae implanted, not in 

 cavities, but on the front margin of the eyes ; in repose they are 

 bent backwards along the breast, the basal joint being shielded 

 between the front angle of the thorax and a carina, which limits the 

 middle and flanks of the prosternum, and impinges on the eye, but 

 there is no distinct antennal groove whatever; their basal joint 

 slender at base but much dilated beyond, second thicker but not 

 longer than fourth, third nearly twice as long as second, joints 6-8 

 submoniliform, club triarticulate, not very compact, basal joints 

 transverse, terminal nearly conical. Thorax transverse, feebly 

 emarginate in front, anterior angles not prominent, very obtuse ; 

 sides undulate, broader behind than in front; base bisinuate, its 

 middle portion a little, but only obtusely, prominent, its angles 

 nearly rectangular and resting on the elytra just inside the shoulders. 

 Scutellum distinct. Elytra large, a little wider than thorax at base, 

 three times its length, closely adapted to it, shoulders just about 

 rectangular, much narrowed behind, apices sharply rounded, in the 

 male leaving the apical ventral segment exposed. Legs elongate, 

 slender; tibiae somewhat bent inwardly beyond the middle, very 

 slightly thickened externally near the extremity, where they are 

 only feebly armed ; tarsi narrow, pilose underneath, not much 

 dilated in either sex. Coxes small, deeply imbedded, the anterior 

 widely separated by the broad prosternal process and distant from 

 the front ; middle pair widely distant, the intervening process flat, 

 simple, truncate in front. Metastemum moderately long, evenly
