dilated among the males, with brush-like soles. Mesosternum often 

 carinated.

274. C. antennalis, ns. Body oblong, slightly oval and convex, 

 reddish, the middle of thorax and elytra pitchy-brown, legs pale reddish- 

 brown, as are also the three basal joints of the antennae, the other joints 

 black. 



AntenncB about as long as the body, slender, pilose ; their two basal 

 joints stout, first cylindric; second shorter than first, sub-ovate; third and 

 fourth equal, rather slender, the latter of equal thickness throughout, 

 third more slender at base than apex; fifth, seventh, ninth, and tenth, 

 ' each a little more dilated at the apex than its predecessor, longer than 

 broad ; sixth and eighth equal, slender, the latter more so, sub-cylindri- 

 cal ; the eleventh shorter than tenth, pointed. 



Eyes rather prominent. Head and thorax shining, the latter a good 

 deal rounded and narrowed in front, the sides behind nearly straight, 

 with rectangular hind angles ; its sculpture consists of irregular linear 

 impressions, and it is sparingly clothed with fine yellowish hairs. Elytra 

 elongate, obovate, rounded individually at their base, with distinct 

 shoulders ; their basal portion is sculptured very much in the same way 

 as the thorax, the rest is irregularly punctate-striate with short transversal 

 impressions, they are finely pilose, the pubescence behind the middle

I found my unique example, a female, at Tairua. 



275. C. alacris, n-s. Similar in form to C. antennalis, but with 

 the legs and antennae differing structurally. It is pitchy-brown, rather 

 dull, the basal portion of the thorax paler, legs and basal half of antennje 

 reddish. 



Antennce a little longer than head and thorax, stout, the two basal 

 joints stout, sub-cylindrical, first the stouter; third and fourth similar to 

 second ; fifth and sixth obconical, the latter as broad as long; seventh 

 obconical, longer than broad ; eighth very small, transverse ; ninth and 

 tenth equal, obconical. each about as long a broad ; eleventh sub- 

 ovate, pointed, yellowish ; they are pubescent. 



Head rather large, eyes not prominent. Prothorax much broader 

 than long, narrowed in front, rounded laterally, with almost acute hind 

 angles ; its sculpture consists of very fine aciculate impressions, and 

 it is clothed with fine yellow hairs, disposed in irregular lines. Elytra 

 elongate, obovate, of the same width as the thorax at the base, im- 

 pressed longitudinally with irregular lines, which are intersected by 

 much finer ones. Legs robust, elongate ; the hind tilncs nearly 

 straight, of about equal thickness throughout ; the middle pair arcuated, 

 and gradually dilated ; the front pair short, stout, a good deal expanded, 

 straight ; front tarsi with the three basal joints considerably dilated, first
