shorter ridge ends at the white mark ; the punctures on the dechvity are 

 subseriate and much finer than those on the dorsum. 



Legs thickly squamose, femora angularly dentate below. Funiculus 

 rather stout, basal joint rather shorter than the second. Club triarticulate, 

 rather narrow. 



Rostral canal deep, limited by the raised crescent-shaped mesosternal 

 process, which is cavernous. Coxae, prosternum, and metasternum coarsely 

 punctate and squamose. Basal ventral segment, in the middle, nearly 

 double the length of the 2nd, rounded there in front, flat, and coarsely 

 punctured ; 5th impressed along the middle. 



Undoubtedly allied to T. bufo Sharp (2182), but much larger, and differ- 

 entiated therefrom by the hind-body being broader than the thorax and 

 having longitudinal ridges. 



Length (rostrum exclusive), 7| mm. ; breadth, 4J mm. 



Silverstream, Hutt Valley. Found on the trunks of black birch {Fagus). 

 A single example received from Mr. H. 8immonds.

 p. 500. 



Variegate, piceo-rufous, thorax nigrescent, densely squamose. 



Rostrum distinctly, yet finely, longitudinally punctate, still more finely 

 in front, the punctures near the base filled with depressed pale-ferruginous 

 scales. Head depressed along the middle. Thorax of nearly equal length 

 and breadth, quite a third of its length, much contracted in front, the basal 

 portion nearly parallel-sided ; subcarinate along the middle, bicristate 

 near the front, its whole surface moderately and closely punctured ; it is 

 covered for the most part with depressed ferruginous scales, the coarser 

 .ones form a pair of antemedian crests, those on the apex are paler and 

 erect. Elytra subcordate, rather wider than thorax at the base, shoulders 

 oblique and densely covered Math slender pale ferruginous squamae ; the 

 disc, as far as the hind thighs, is on a higher plane than the thorax, and is 

 covered with small scales of a lighter colour ; at the base there is a pair 

 of small blackish spots, and a few minute granules near the suture ; at 

 each side of this area there are 2 moderate crests, and 2 or 3 others nearer 

 the sides ; the posterior declivity forms a long curved slope, covered with 

 small ferruginous scales, some dark, others bright ; this part is sub- 

 striate-punctate, bears several minute crests and 3 larger ones near each 

 side ; the punctures near the sides are much coarser and less regular. 



Femora medially angulate. Tarsi rather narrow, their basal joint 

 quite as long as the terminal, 3rd moderately expanded and bilobed. 

 The scape attains the eye. Basal joint of funiculus evidently shorter 

 than 2nd. Club elongate-oval, triarticulate and acuminate. 



Underside with depressed ferruginous and flavescent squamae. 

 Pectoral canal profovmd, bounded by the strongly raised border in line 

 with the back of the middle coxae. Metasternum very short. Basal 

 ventral segment quite double the length of the 2nd, moderately coarsely 

 and very closely punctured, subtruncate behind and more elevated there 

 than in front ; 2nd medially raised ; 3rd and 4th flat, on a lower level 

 than the preceding one, and, at the sides, nearly as long as it is ; 

 5th deeply impressed at each side. 



In form somewhat similar to C fasciculatus (2574), the basal portion 

 of the thorax less sharply defined in front owing to the absence of lateral
