1474 COLEOPTERA 



stout, femora clavate but slender near the base ; tibice a little bent, 

 the anterior distinctly arched beyond the middle, the inner ex- 

 tremity mucronate ; the setse en the legs are short; tarsi short, 

 their second joint transverse, the penultimate sublobate. 



This is a much narrower msect than C. aurisetifer ; the eyes are 

 rather larger ; the head is more immersed ; the scape is not so 

 slender at the base ; the funiculus is somewhat different ; the scrobe 

 is foveiform, but a shallow lateral groove extends to the eye. Not- 

 withstanding these differences I think the tw^o species may be placed 

 together, at any rate for the present. 



Length (rost. inch), If lines; breadth, f line. 



Mount Pirongia. A solitary specimen ; another of Mr. A. T. 

 Urquhart's leaf-mould novelties. 



2553. C. thoracicus, 'i--^'- Subovatc, not narrow, subopaque ; 

 elytra and tibiae fuscous, thorax and beak reddish, femora more or 

 less testaceous, the antennae of a paler red than the tarsi ; the 

 clothing irregularly distributed, consisting of very small, scale-like 

 yellow setae. 



Iiostruvi longer than the thorax, parallel, arched, closely and 

 finely punctured in front, bicarinate behind. Antennce inserted 

 before the middle. Scape slender, its apex clavate, with minute 

 yellow setae. Second joint of the fttnicuhis as large as the first, if 

 not larger, 3-6 shorter, each a little broader than its predecessor, 

 seventh a good deal larger than the sixth ; club ovate. Thorax as 

 broad as it is long, the middle of the base depressed, widest at the 

 middle, slightly rounded there, more narrowed in front than behind, 

 base truncate, apex slightly incurved ; its surface a little uneven, the 

 punctures rather small and irregular, so that there is a smooth space 

 on each side of the middle in front. Elytra ovate, base subtruncate, 

 with a very slender margin across the middle, where it is depressed ; 

 the sides very slightly curved, widest at, or behind, the posterior 

 femora ; they have series of rather shallow', not closely placed, punc- 

 tures (sometimes with slightly-raised transverse intervals), there are 

 two such rows, on each elytron, near the suture, those beyond are 

 irregular ; in line with the fourth and fifth interstices there are two 

 large but only slightly-raised spots covered with small setae, a third 

 one, placed further back and nearer the side, bears coarser setse ; 

 just before the top of the declivity, which is not at all abrupt, the 

 setae are more concentrated, and they form small spots on the slope 

 itself. Legs sparsely setose. 



The head is much smaller than it is in C. aurisetifer. The inner 

 extremity of the front tibiae is not perceptibly produced and acute, 

 as it is in C. flavipes, which is of different form. Although this 

 does not agree exactly with the typical species, I fail to find good 

 distinguishing generic characters. 



The incurved thoracic apex is distinctive. 



Length (rost. excl.), 1-^ lines ; breadth, % line. 



Mount Pirongia. One, picked out of leaf-mould brought by Mr. 

 A. T. Ur(|uhart.
