cent at the extremity ; the internal membraneous inwardly. Mandibles 

 short, furnished inwardly with a straight, fringed membrane. Labrum 

 transversal, entire. Head transversal, trigonal, bent below. ' Eyes some- 

 what prominent, moderate, rather convex, almost rounded. Antenna 

 rather long, slender, filiform, or gradually increasing towards the ex- 

 tremity ; the three or four first joints rather longer than the succeeding. 

 Prothorax large, rather convex, truncate at the base, which slightly 

 overlaps the elytra and is wider than them, narrowed anteriorly, with 

 acute front angles. Elytra longer than the sternum, their terminal 

 angles straight. Abdomen not margined laterally, strongly narrowed 

 posteriorly. Mesostermim carinate. Anterior femora ciliated at the 

 extremity ; the tibia of the other pairs fringed throughout their whole 

 length ; the four basal joints of all the tarsi gradually decreasing, those 

 of the four posterior very long and smooth. 

 Body clothed with silky pubescence. 



177. C. largulUS, n.s. Antenna long, their four basal joints 

 yellowish and more or less shining ; the first not longer than the third 

 or fourth, which are slender and about equal, second shorter than 

 third ; joints five to ten fuscous, darkest near the sides, obconical, each 

 shorter than its predecessor ; eleventh sub-ovate, obliquely excised at 

 its apex. Head red, blackish at the sides and base, shining, not very 

 perceptibly punctulate, and bearing a few short yellow hairs, more con- 

 spicuous near the eyes than elsewhere. Prothorax large, curvedly 

 narrowed anteriorly, delicately and closely punctulated, sparingly clothed 

 in the same way as the head ; the disc is convex, blackish-brown, more 

 glossy than the rest of its surface and nearly nude ; the base and front 

 are reddish. 



Elytra longer than prothorax, margined laterally, each obtusely 

 rounded and reddened behind, rather dull reddish-brown, punctulate, 

 and clothed with short, dull yellow hairs. Abdomen not twice the 

 length of the elytra, dark brown, the segments somewhat rufescent 

 behind, clothed and sculptured very much in the same manner as the 

 elytra, each segment with three or four black hairs at each side, the 

 sixth bearing, in addition, several others above. Legs reddish-testace- 

 ous; the intermediate tibia considerably bent, the four posterior 

 sparingly spinous.

I found two specimens, one at Tairua, the other at Parua (Whan- 

 garei Harbour.) 



178. C. austerus, n.s. Antenna moderately long, reddish-tes- 

 taceous, similar in structure to those of C. largulus, but with the last 

 six joints less triangular in form, and the terminal decidedly larger than 

 the preceding. Head dark red, sparsely punctulate and pubescent. 

 Prothorax dark smoky brown, paler behind, not much shining, finely 

 punctulate, and clothed with short yellow hairs. Elytra shorter than 

 the prothorax, rather more distinctly punctulate, its colour and pubes- 

 cence, however, very similar. Abdomen of the same colour, with the
