397. C. Silvanus, /i.s. Slightly convex, oblong, elliptical, the 

 head and thorax perceptibly narrower than the elytra, sparingly clothed 

 with rather short and fine pale yellow hairs ; it is shining, with red 

 antennae, reddish head and thorax, chestnut-red elytra and legs, with 

 more or less apparent fuscous marks near the base and apex of the 

 elytra. 



Antennce stout, shining, sparingly pubescent, longer than head and 

 thorax ; their two basal joints stout, the first the larger ; third a little 

 longer than second, more slender, thickened at ai)ex ; joints four to 

 eight bead-like, longer than broad, the fifth slightly longer than the 

 contiguous ones ; club three-jointed, the ninth joint larger than eighth, 

 tenth than ninth, the last largest, subovate. Head moderately coarsely 

 but not closely punctured. Thorax sub-quadrate, not very much broader 

 than long, not perceptibly sinuated laterally, and about as broad in 

 front as behind ; the apex is rounded, so that its middle part is a little 

 in advance of the angles, which are distinct but not acute ; the base is 

 bisinuated, with acute slightly carinated angles directed backwards ; the 

 disc is convex, there is an almost continuous basal depression, its entire 

 surface is distincdy but not closely punctured, and the lateral rims are 

 indistinct. Seiitellum transverse. Elytra oblong, but little rounded at 

 their sides, indistinctly impressed behind the base, humeral angles some- 

 what oblique and slightly elevated above; they are more finely punctured 

 than the thorax, the punctation is not arranged in rows, and each has 

 a distinct sutural stria. Legs rather long and slender.

One example found at Tairua. 



398. C- ang'Ulifer, n.s. Oblong, moderately convex, sub-parallel, 

 shining, chestnut-red (pale), base of elytra infuscate, antenna? red, legs 

 reddish-yellow ; it is sparingly clothed with short greyish hairs, so 

 disposed as to leave the whole of the dorsal space quite nude, but this 

 circumstance, it is probable enough, may be attributed to abrasion. 



Antennce rather short, hardly longer than head and thorax, iheir 

 structure similar to that of C. ruhcUus, but rather slender in proportion 

 to the size of the insect as compared with that species. Head distinctly 

 and rather closely punctured. Thorax transversely quadrate, a good 

 deal broader than long, apex rounded, base slightly bisinuated ; it is 

 widest in front, owing chiefly to the very prominent yet not at all acute 

 front angles, it is somewhat acutely angulated laterally near the middle, 

 and narrowed from thence in front and behind, but not sufficiently to 

 render the outline other than subtjuadrate ; its surface is closely and 

 distinctly punctured, and indistinctly impressed along the base. Elytra 

 a little wider than thorax, slightly wider at the middle than elsewhere, 

 not quite so coarsely and much more remotely punctured than the 

 thorax. Legs rather elongate ; tarsi linear, the posterior not quite so 

 long as the tibiae.
