402 COLEOPTERA 



I found one mutilated individual at Tairua measuring 3^ lines, and 

 quite recently, at Whangarei Heads, a perfect specimen which is scarcely 

 three lines in length ; the larger one is nearly one line broad, the smaller 

 three-fourths of a line. 



708. C. fuliginosa, n.s. Convex, elongate, parallel ; body of a 

 moderately shining, sooty-brown colour, with fine pallid pubescence ; 

 legs, antennae, and palpi reddish. 



Thorax sub-conical, rather short, the sides rounded, but nearly 

 straight behind, so that the posterior angles, which are not acutely pro- 

 longed, do not overlap the shoulders of the elytra, base bisinuated ; the 

 surface is very finely and rugosely sculptured, with an indistinct trans- 

 verse scutellar depression. Scutellum distinct, rounded. Elytra elon- 

 gate, almost parallel, the sides being very gradually narrowed towards 

 the apices, which are rather obtusely rounded and not at all divergent ; 

 their sculpture consists of ill-defined slightly elevated longitudinal lines, 

 with intervening depressions and a very fine rugose punctation some- 

 what similar to that of the thorax ; the suture and margins are simple. 

 The antcunce are rather long and slender, but of the orthodox pattern. 

 The two posterior pairs of tibia are serrated externally. The maxillary 

 palpi have a small basal joint, the second is large and of triangular 

 form, the penultimate is sublunate at the apex, but rather acutely pro- 

 duced, and the terminal joint is cultriform. The eyes are large but not 

 coarsely facetted. 



This insect is decidedly more elongate and parallel-sided than 

 Redtenbacher's species, but it does not exhibit structural differences to 

 warrant its removal from Ctenopkctron. I think it would be better to 

 regard the peculiar sculpture of the suture and margins of the elytra, as 

 detailed in Redtenbacher's generic diagnosis, as of specific value only, 

 as it seems evident that other species will be discovered, which, if this is 

 not done, will have to be associated under another generic name, though 

 ([uite normal in other respects. 



I found two examples at Tairua, both imperfect ; they measure 5 

 and 5^ lines recpectively.
