and Species o/Heteromera. 477 



the elytra, distinctly more shining, the punctuation &c. on the 

 elytra coarser, more confluent and confused, somewhat ruggedly 

 so at the sides ; the sides of the pro thorax more rounded, more 

 incurved at the base, the median basal lobe more prominent ; 

 the base, consequently, has not that appearance of being 

 bisinuate-emarginate as is the case in C. opacula. 



Head closely punctured, the punctures coarsest and some- 

 what confluent on the front, between the eyes, where there are 

 also usually two more or less marked J foveate depressions : 

 prothorax more or less strongly transverse ; sides more or less 

 regularly rounded, more narrowed in front than behind, always 

 distinctly and more or less sinuously incurved before the hind 

 angles ; apex deeply arcuate-emarginate, the angles prominent, 

 subacute, and usually directed forwards ; base bisinuate, the 

 angles more or less prominent and acute, reposing on the 

 shoulders of the elytra, and directed backwards ; disk mode- 

 rately convex, very closely (save on the centre) punctured, the 

 interstices a little elevated, and more or less reticulate, at the 

 sides ; a transverse depression subparallel and near to the 

 base, and an angulate fovea at each side, close to the basal 

 margin (as in ? ? of C. opacula) ; sides moderately expanded, 

 the edges unequally (not uniformly) thickened ; scutellum as 

 in C. opacula : elytra oblong-oval, base sinuate-truncated ; 

 disk moderately convex, closely and more or less confluently 

 punctured ; the interstices (especially at the sides) elevated, 

 minutely granulose, reticulately confluent, sometimes assuming 

 the form of irregular nodules, at others of small umbilicated 

 tubercles ; the ordinary series of narrow costae and the row 

 of foveas within the side-margins more or less apparent ; 

 sides rather strongly expanded, concave, transversely reticu- 

 lately rugose-punctate and granulous : underside, legs, an- 

 tennae, &c. as in G. opacula. 



Length 7£-8£ lines ; width of elytra 3f-4 lines. 



Hah. Otago, New Zealand. Four examples. 



Var. ? grandis. 



Larger (length 9 lines ; width of elytra 4-f lines) ; the elytra 

 less convex, distinctly more gradually declivous behind ; the 

 punctuation &c. (on the elytra especially) coarser, the punctures 

 larger, the interstices 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 surface of a browner 

 colour. 



Hah. New Zealand. One example.
