OF NEW ZEALAND. 371 



Var. ? grandis. 



Larger (length, 9 lines ; width of elytra, 4! lines) ; the elytra less 

 convex, distinctly more gradually declivous behind ; the punctation, 

 &c. (on the elytra especially), coarser, the punctures larger, the inter- 

 stices still more elevated and more uniformly reticulate; the apical 

 emargination of the prothorax distinctly sinuous ; the tibiae (especially 

 the anterior) distinctly less closely punctured and the entire upper sur- 

 face of a browner colour. 



New Zealand. One example. 



668. C. elongata, Breme, and C. phosphugoides, White ; Ann. 

 Mag. Nat. Hist., Dec., 1873. Examples of C. elongata obtained from 

 the collections of Reiche and Doue (presumably authentic exponents 

 of the species) do not differ from C. phosphugoides except in the form 

 of the prothorax, which in the former has the sides more obliquely nar- 

 rowed anteriorly, and the elytra, which are more acuminate behind. 

 Experience has shown us that these differences possess no true specific 

 value in this genus ; C. phosphugoides must consequently be sunk under 

 C. elongata. 



This species is much smaller than any of those preceding ; the 

 form is more or less elongate-oval ; prothorax shining black ; the 

 expanded lateral margins paler ; the elytra are of a more or less deep- 

 purplish or chocolate-brown. Head convex between the eyes, trapez- 

 oidal in front, with the borders usually dark-ferruginous, more or less 

 strongly, closely, and sometimes rugosely punctured ; epistoma convex, 

 more or less distinctly arcuate-emarginate in front, the sutural impression 

 more or less distinct ; the form and punctation of the prothorax is 

 variable ; it is always of a shining black, convex, a depression on the 

 middle near the base, another smaller at each side at the basal margin ; 

 usually very finely and not closely punctured on the disc, the punctures 

 more crowded at the sides and finely rugulose, more or less distinctly 

 granulous on the intervals ; lateral margins moderately expanded and 

 concave, the edges finely and uniformly thickened ; apex deeply emar- 

 ginate, front angles more or less acute, and usually a little convergent, 

 sometimes directed forwards ; base closely applied to the base of the 

 elytra, bisinuate, hind angles prominent, reposing on the shoulders of 

 the elytra, acute, usually a little outwardly directed; ordinarily the sides 

 are a little sinuously contracted posteriorly, but sometimes they are sub- 

 parallel (in this latter case the base is as wide as the base of the elytra) 

 anteriorly they are always more strongly contracted, sometimes very 

 gradually (obliquely) from behind the middle, at others more abruptly 

 (curvedly) from the middle or even before the middle ; scutellum trans- 

 versely triangular, punctured ; elytra oval, more or less acuminate 

 behind, convex, subopaque, of a dark purplish-brown ; frequently the 

 base (narrowly), the suture, the expanded margins, and the scutellum 

 are of a reddish tinge ; base sinuous, and generally a little wider than 

 base of prothorax ; expanded lateral margins narrow, concave, not dis- 

 tinctly reaching the apex ; disc with numerous more or less distinct 

 longitudinal costse, irregularly punctured, finely rugose (most strongly 

 at the sides), and studded with very distinct, shining, black granules ;
