OF NEW ZEALAND. 625 



are not very close ; the others are coarser and somewhat rugose. Elytra 

 obovate, with two more or less distinct marginal striae on each, the rest 

 of their sculpture consists of regular rows of rather fine punctures, with 

 a few others interposed between the rows near the base, the lateral 

 punctures are coarsest, and the slightly elevated shoulders are quite 

 smooth. 



This species, though similar in form to the preceding three, may be 

 at once identified by the sparingly punctured elytra ; the lines on the 

 head are not always so distinct as in the typical specimen, which has 

 slightly more protuberant anterior thoracic angles than the other. 



Length, ij; breadth, f line. 



I found two examples near Whangarei Heads. 



1097. C. brevicollis, n.s. Testaceous, with two distant thoracic 

 vittse, the base and suture, and a broad space on the side of each 

 elytron, fuscous. Head sparingly punctured, with a short impressed 

 line on the vertex. Thorax broad, very short, margined, slightly bi- 

 sinuated at the base, the sides a little rounded, not much narrowed 

 anteriorly, and the front angles but little depressed, and, therefore, 

 appearing rather prominent ; the sides and base are almost impunctate, 

 and the elongate punctiform impressions are somewhat congregated on 

 the darker spaces and apex. Elytra obovate ; their sculpture consists of 

 regular rows of punctures with others on the intervals near the base, and 

 there is a not very obvious stria near the marginal channel, and another 

 near the suture. 



Length, if; breadth, J line. 



This species resembles what I believe to be the C. pallidipennis of 

 White, but can be at once known by its short broad thorax. 

 My only specimen was found near Whangarei Heads. 



1098. 0. atrOCeruleilS, n.s. Body blackish-blue, legs somewhat 

 infuscate, antennae black, with the apex of each joint tawny. Head very 

 smooth, scarcely elevated at the point of insertion of the antennae. 

 Thorax transverse, base moderately bisinuated, finely margined, front 

 angles depressed, the sides a little rounded, and obliquely narrowed 

 near the hind angles ; the punctation of the dorsal space is fine and 

 remote, that of the sides coarser. Elytra obovate, the disc with rows of 

 rather fine punctures, with others on the intervals near the base, there 

 are some indistinct striae near the apex, two furrows near the side, 

 which, behind the shoulder, is coarsely and rugosely punctured. 



Length, if; breadth, f line. 



I found two individuals near Whangarei Heads. 



1099. C. OCliraceuS, n.s. Oblong, of a yellowish-brown colour, 

 the legs and antennae paler than the body, and slightly reddened in one 

 of my specimens. 



Head a little uneven, more or less punctate, with, in some examples, 

 a distinctly impressed line on the vertex. Thorax much broader than 

 long, margined, with the anterior angles depressed, the posterior small,
