OF NEW ZEALAND. 237 



Head coarsely and rugosely sculptured, rather broad behind. Pro- 

 thorax about as long as broad, rounded laterally, a good deal narrowed 

 in front, coarsely and rugosely punctured, and rather uneven; there 

 being a short oblique elevation at each side near the middle, a lateral 

 depression behind each of these, and two dorsal impressions. Elytra 

 rather broad, convex, oviform, a little depressed at the suture near the 

 base, and coarsely and somewhat rugosely punctured. 



Length, | line. 



I found two or three examples near Whangarei Heads. 



421. C. obesa, n.s. Convex, shining, almost destitute of pubes- 

 cence, there being only a few fine short pallid hairs proceeding from the 

 punctures ; it is of a dark, somewhat bronzy-chestnut colour, with red- 

 dish-testaceous legs and antennae, but with the club of the latter fuscous. 



Head and thorax with indistinct, rather distant punctures ; the latter 

 convex, about as long as broad, with moderately rounded sides (not 

 cordiform), and a little depressed near the base. Elytra convex, obovate, 

 a good deal narrowed towards the apex, with rounded shoulders which 

 are not at all prominent ; they bear distinct well-defined punctures almost 

 arranged in rows, and the interstices are quite smooth and shining. 

 The antenna are about as long as the head and thorax, their two basal 

 joints are stout, three to eight small, the latter scarcely more developed 

 than its predecessor, club elongate.

Described from one example found at Auckland. 



422. C. pudibunda, n.s. Somewhat similar to C. obesa, but less 

 robust; it is convex, not very broad, almost nude, of a moderately 

 shining reddish colour, with the legs somewhat testaceous. 



The head and thorax are coarsely and closely punctured, the latter 

 about as long as it is broad, rounded laterally and rather convex, with a 

 small basal fovea. The elytra are convex, obovate, and almost rugosely 

 punctate, with very fine almost indistinct hairs proceeding from the 

 punctures, and slightly depressed near the scutellum.

My only specimen was obtained at Tairua. 



423. 0. alacer, n.s. Moderately convex, shining, pubescent, the 

 head castaneous-red, thorax blackish, elytra reddish-yellow, the legs, 

 antennae, and pubescence yellow. The antenna are as long as the head 

 and thorax, their two basal joints are stout, the second the shorter ; 

 joints three to eight about equal ; club loosely articulated. The punc- 

 tation of the head and anterior half of the thorax is rather coarse, that 

 of the elytra less dense, whilst the hind part of the thorax is rugulosely 

 sculptured and free from punctures. 



The prothorax is longer than broad, dilated laterally at the middle, 

 its front and base scarcely so wide as the head (including the distinctly 

 facetted eyes), and most elevated at the middle. The elytra are obovate, 

 moderately convex, considerably wider than the thorax, impressed
