OF NEW ZEALAND. 229 



Prothorax subconical, broader than long, front angles depressed, yet 

 less obtuse than the posterior, the sides are a little rounded, apex sub- 

 truncate, base bisinuated ; the surface is coarsely punctured, and its 

 pubescence is unevenly distributed, chiefly near the sides and base. 

 Scutellum sub-quadrate. Elytra sub-oblong, transversely convex, of the 

 same width as the thorax at the base but somewhat broader behind ; 

 they are not striate, being finely and irregularly sculptured, so as to 

 appear rugulose ; the base space is more or less reddened, and the 

 yellowish hairs are more congregated there than elsewhere. Legs 

 moderately long and slender. Under-side blackish, with fine greyish 

 pubescence. 



Length, I-IT line; breadth, nearly \. 



Not uncommon on the Nikau. 



This and the four following species are congeneric, and must ulti- 

 mately form a new genus. 



402. C. SUbstriatuS, n.s. This species so much resembles C. 

 fuliginosus that it will be unnecessary to do more than point out wherein 

 the two differ. This insect is darker in colour and more glossy, not 

 only the base but the apex also of the elytra are dilute in colour, as 

 well as in some examples the same parts of the thorax, the legs, and 

 antennae are infuscate-testaceous ; the punctation of the thorax is less 

 dense ; the posterior half of the elytra is finely sculptured, but the rest 

 is almost striated, with rows of coarse punctures ; the body is much more 

 sparsely clothed, and the eyes are less conspicuous. 



Length, ii line ; breadth, i. 



Professor Hutton sent me a few specimens from Otago, and I found 

 one at Tairua. 



403. C. aciCUlatUS, n.s. Oblong-oval, convex, sparingly clothed 

 with fine short griseous hairs ; it is piceous, with a humeral spot on each 

 elytron, the legs, and all but the club of the antennae, reddish-testaceous. 

 Head with four longitudinal raised lines, formed apparently of minute 

 granules. Thorax a good deal rounded, and narrowed towards the 

 front, and so sculptured as to appear as if irregularly scratched with a 

 needle. The elytra are similarly but more finely impressed on the disc, 

 with some fine punctures behind. In other respects the form and 

 appearance correspond with those of C. fuliginosus. 



Length, i line ; breadth, quite J. 



I found one example near Whangarei Heads. 



404. C. SerratUS, n.s. Oblong-oval, convex, shining, castaneous, 

 covered with fine yellowish hairs, legs testaceous, antennae shining, red- 

 dish, with an infuscate club. 



Head moderately finely punctured; thorax rounded and narrowed 

 anteriorly, its sides serrated, and the surface with short irregular acicu- 

 late impressions, with small punctures on the otherwise smooth intervals; 

 elytra with numerous fine scratch-like marks similar to those observable 

 on the prothorax, and minute punctures on the interstices.
