230 COLEOPTERA 



Legs slender. In form and structure this species is very much hke 

 C. fiiligiuosus. 



Length, \\ Hne ; breadth, quite \. 



I found four specimens near Whangarei Heads. 



Obs. — In C. aciculatus the intervals between the aciculate impres- 

 sions appear elevated and roughened, but in the present species the 

 surface seems smooth, though finely scratched. The colouration is 

 variable, some individuals being pale, others reddish, castaneous. 



405. O. punctulatus, n.s. Ovate, convex, moderately shining, 

 finely and sparingly pilose, castaneous, legs testaceous, antennae reddish, 

 club brownish. 



Antennce. rather slender, their third joint longest, fourth and fifth 

 equal, obconical, sixth and seventh moniliform, eighth transversal. 

 Head rather shining and finely punctured. Prothorax rounded and 

 narrowed towards the front, with the front angles deflexed, causing that 

 part of the thorax, when viewed from above, to seem narrower than it 

 really is ; its surface is moderately punctured. Elytra punctulated, 

 with a few excessively fine aciculate marks irregularly disposed over 

 their surface, their pubescence is fine, not very close, and evenly distri- 

 buted.

I found two examples near Whangarei Heads. 



It may be easily recognised by its small size, pale reddish chestnut 

 colour, and fine elytral sculpture. 



406. C. adspGrSUS, n.s. Sub-ovate, rather elongate, moderately 

 convex, rather dull, pitchy-brown, somewhat variegated with small spots 

 formed by short yellowish hairs, the legs and antennal club are infuscate- 

 red, the rest of the antennae reddish. 



Head rather closely and coarsely punctured, with prominent eyes ; 

 prothorax broader than long, its widest part behind the middle, a little 

 .contracted towards the hind angles, which are almost acute ; narrowed 

 anteriorly, with depressed front angles, so that the base appears to be 

 wider than the apex, which is sub-truncate, and its base bisinuated ; it 

 is finely margined, indistinctly impressed down the middle, rather 

 closely and moderately coarsely punctured, appearing somewhat rugose 

 and dull, with fine short yellowish hairs irregularly distributed in patches, 

 chiefly near the sides and base ; scutellinn transversely quadrate ; elytra 

 not much broader than the thorax, elongate, indistinctly depressed in 

 front of the middle, with a few reddish spots, most conspicuous on the 

 shoulders; their basal half is so impressed with coarse punctures in rows 

 as to have a striate aspect, the remaining portion is more irregularly but 

 much more finely sculptured; their pubescence is variegated, the yellow 

 hairs are congregated in irregular patches, giving the elytra a spotted 

 appearance. The legs are rather slender. The antennce are- slender, 

 pubescent, hardly so long as the head and thorax, with a three-jointed 

 club ; their basal joint is stout, not much exposed ; the second about as 

 long as but stouter than third, which is longer than the fourth ; the
