brown, the entire insect sometimes reddish brown; most nitid on the pro- 
thorax; rather convex: head rather long, rather finely and closely 
punctured ; a distinct, transverse, slightly bowed impression across the 
front between the eyes: epistoma broadly truncated in front, the suture 
rather strongly marked and angulate at the sides; prothorax very finely 
and, on the middle, remotely punctured; a strong angulate impression at 
each side close to the basal margin, and sometimes an obscure transverse 
impression between them; apex moderately emarginate; anterior angles 
subacute, directed forwards ; sides more or less regularly rounded, more 
contracted anteriorly than posteriorly, occasionally a little sinuous before 
the front angles; hind angles more or less (sometimes almost imperceptibly) 
_ outwardly produced, acute ; lateral margins very slightly expanded, a little 
concave, the edges moderately and almost uniformly thickened: elytra 
oblong-oval, feebly sinuous at the base; shoulders more or less distinctly 
rounded ; punctuation, etc., almost as in C. tibialis, but the interstices, 
especially at the sides, are more distinctly rugulose; expanded lateral 
margins narrow, almost obsolete (or strongly narrowed) at the base, scarcely 
perceptibly continued to the apex, a little concave, the edges sometimes 
slightly reflexed at the base: markings on the underside similar, but much 
feebler, to those in C. tibialis; legs, antennw, and epipleural fold reddish 
piceous ; anterior tibie acute (but not at all dentiform) at the outer apical 
angle. 
Length 63-8 lines ; width of elytra Q:-82 lines. 
Hab. New Zealand. Five examples. 
The oblong or elongate-oval form, the transverse impression between 
the eyes, the almost smooth prothorax in contrast with the somewhat 
coarsely sculptured elytra, the scarcely expanded sides of the prothorax, 
and the lateral expanded margins of the elytra obsolete at the base, will 
serve to distinguish this species. 
Artystona, n. g. 
Differs from Titena in the prosternum less strongly and abruptly 
elevated between the coxe, not distinctly concave in front of them, the 
anterior horizontal portion longer; the head consequently is less deeply 
imbedded in the prothorax, and does not repose on the front coxew. Pro- 
thorax squarer, less convex, truncated at base and apex, more or less finely 
punctured. Lateral reflexed margins of the elytra distinctly terminating at 
the humeral angle; the punctuation of the surface of the elytra is in rows 
of fine punctures, the intervals being convex, interrupted, and forming, 
especially at apex, series of oblong tubercles. Legs longer and (especially 
the tarsi) more slender, Body not pilose.
