OF NEW ZEALAND. 225 



terminated by a horny hook. Mandibles short, arched, furnished with a 

 molar tooth at their base, with a ciliated membrane in front of this 

 tooth, and denticulated. Labritm quadrate, transversal. Head trigonal, 

 sunk in the prothorax as far as the eyes ; the latter large, prominent, 

 rounded, and strongly granulated. Anteimce rather robust, first joint 

 stout, pyriform, second a little longer than seventh and eighth, which are 

 equal, nine to eleven forming a rather compact club, ninth equal to 

 tenth, or a little "less thick. Prothorax transversal, truncated in front, 

 slightly rounded and denticulated on the sides, more or less bisinuated 

 at its base, and frequently having an impression near each of its hind 

 angles. ScuteUuiii transversal. Elytra oblong-oval, more or less convex. 

 Tarsi heteromerous among the males, pentamerous among the females. 

 Prosternitm hardly, or not at all, received into the mesoternum. Body 

 oblong-oval, slightly or considerably convex. 



Note. — The following species do not, strictly speaking, belong to 

 this genus (except perhaps C. aiistralis, Redten.), and will be re-arranged 

 when more material can be accumulated for microscopical examination. 



393. C australis, Redtenbacher ; Voy. Novara, Zool. Oblongus, 

 subconvexus, parce longe pilosus, ferrugineus, ore, antennis, pedibusque, 

 flavo-testaceis ; tJiorace valde transverso, lateribus obsolete crenulatis, 

 antice angustato, angulis simplicibus ; elytris vage punctatis, ante apicem 

 evanescentibus. 



Long., 1-^, ; lat, x\ lin. 



394. C. rubellus, n.s. Oblong, sub-parallel, slightly convex, shining; 

 elytra of a light chestnut-red colour, head and thorax darker red. legs 

 and antennae shining, red, the latter darker than the legs ; elytra clothed 

 with distinct yellow hairs, the head and thorax more sparsely with finer 

 ones. 



Antenna stout, longer than head and thorax, pubescent, eleven- 

 jointed ; basal joint longer and stouter than second, which is sub-ovate 

 and much larger than third ; joints three to eight moniliform and about 

 equal to one another, the fifth, however, larger than the contiguous ones; 

 club three-jointed, loosely articulated, the two first joints longer than 

 broad, the last rounded. Head trigonal, with prominent coarsely facetted 

 eyes ; rather coarsely but not closely punctured. Prothorax transversely- 

 quadrate, the frontal portion just behind the head sub-truncate and a 

 little produced, so that the front angles do not extend so far forward, 

 these are prominent but obtuse, and extend laterally so that they are 

 wider than the head in line with the eyes ; it is margined, narrowed 

 behind, with almost straight sides, the base is bisinuated so as to appear 

 obtusely lobed at the middle, and the posterior angles are acute, and 

 directed towards the shoulders of the elytra ; its surface is sparingly 

 impressed with rather large, shallow punctures, and it is more or 

 less obviously depressed near the hind angles. Sciitellinn transverse, 

 widest behind. Elytra a little wider than thorax at the base, but of 

 about the same width as its frontal portion, they are very slightly nar- 

 rowed behind, a little depressed above near the middle, with a distinct 

 suture ; they are not perceptibly striate, but bear rows of punctures very 

 similar to those on the thorax.
