OF NEW ZEALAND.

more distinctly granulose, and the punctation a little finer and closer : 

 underside, &c., as in C. huvieralis. 



Length, a\-S\ ^i^^s ; width of elytra, 2j-2f lines. 



New Zealand. Five examples. 



673. 0. granulosa, De Brcme; Bates in Ann. Mag. Nat. Hist., 

 Dec, 1873. Easily recognizable by its usually squalid aspect, and 

 coarsely sculptured and closely granulose surface. The humeral angle 

 is more or less strongly prominent ; the expanded lateral margins of the 

 elytra broad and concave ; and there is at the sides a more or less dis- 

 tinct sinus behind the humeral angle ; the costae on the elytra are moe- 

 conspicuous (especially at the base) than in any of those preceding. In 

 some examples we can perceive on the elytra a very minute pubescence. 



Length, 5I-64 lines; width of elytra, 20-3^ lines. 

 New Zealand. Six examples. 



674. C. rug-OSa, Bates; Ann. Mag. Nat. Hist., Dec., 1873. Near 

 C. granulosa, but distinctly narrower ; the expanded lateral margins of 

 the elytra very narrow, not concave, except slightly at the base ; the 

 surface of the elytra distinctly punctured, reticulately rugose, not granu- 

 lose, or granulose-punctate, and with three distinctly prominent cost^ on 

 each ; humeral angles not prominent, the sides not sinuous behind them; 

 and the anterior tibise have the outer apical angle strongly dentiform. 



From the following ( C. tibialis, the only other species having the 

 outer apical angle of the anterior tibise dentiform) it may be known by 

 its different form, somewhat squalid, opaque surface, the elytra distinctly 

 rugose, costate, and pubescent ; the prothorax more deeply emarginate 

 at apex, the front angles more prominent, the hind angles not acutely 

 produced, &c. 



Broion, slightly squalid ; head (except the epistoma) and prothorax 

 coarsely punctured, the interstices narrow, appearing a little elevated, and 

 a good deal broken up on the front of the head and the base of the 

 prothorax, allowing the punctures to run confusedly together. Head 

 trapezoidal in front ; sides of epistoma almost completely continuous 

 with the antennary orbits, the angles slightly rounded : prothorax arcuate- 

 emarginate in front, the angles a little produced, subacute, directed 

 forwards'; sides regularly but moderately rounded, more narrowed 

 anteriorly than behind, a little sinuous in front of the hind angles, these 

 latter not acutely produced, slightly divergent ; the three impressions by 

 the base as ordinary, the two outer strongly marked, and another round- 

 ed depression on the middle, at each side of the median line : elytra 

 rather strongly narrowed behind, humeral angles not prominent ; sides 

 slightly rounded from the humeral angles, not at all sinuous behind them; 

 the surface somewhat coarsely punctured, very distinctly reticulate- 

 rugose, and very thinly clothed with a short, minute, rigid, pale golden 

 pubescence, on each elytron three very distinct costse, with a much 

 fainter one between them ; these send out irregular, lateral, elevated 

 branches, which cause the reticulate-rugose appearance before mentioned, 

 the interstices being somewhat squalid ; the punctation, costag, &c.
