and Species of Heteromera. 481 



Length 5^-6 lines ; width of elytra across the middle 2^- 

 3 lines. 



Hah. New Zealand. Four examples. 



In the ? ? the form is slightly more expanded, the prothorax 

 slightly more transverse, the sides less strongly narrowed an- 

 teriorly, and the punctuation of the elytra a little more open. 



The three species last described are very near to each other ; 

 but I think there is ample justification, at present at least, in 

 holding them distinct. The species last described is of a more 

 oblong form (especially in the c? ?) than the others; the prothorax 

 has not the same glossy blackness as in elongata ; and the 

 elytra are less opaquely roughened, more closely punctured, and 

 much less distinctly granulose ; the humeral angle is much 

 more prominent, the lateral expanded margins broader and 

 strongly concave within the humeral angle. From Pascoei it 

 may be known by its narrower and more oblong form, finer 

 and closer punctuation, and more narrowly expanded lateral 

 margins. 



In this species the prothorax is still more decidedly elon- 

 gated (but is yet wider than long) than in the preceding. Form 

 elongate-oval ; entirely of a dark brownish black, subopaque. 

 Head and prothorax (save on the middle of the disk) closely 

 punctured, the punctures rounded, a little more crowded at the 

 sides of the latter, the interstices distinctly punctulate ,* sides 

 of prothorax gradually and but slightly curvedly narrowed from 

 near the hind angles to the apex, distinctly incurved at the 

 hind angles, which are more produced than in humeralisj and 

 slightly convergent or directed inwardly ; apex deeply eraar- 

 ginate, front angles subacute, slightly convergent ; expanded 

 lateral margins moderately wide, scarcely concave, the edges 

 finely and almost uniformly thickened ; a rather slight sublu- 

 nate impression at each side of the middle, close to the basal 

 margin, and another, still less distinct, rounded fovea above and 

 in front of them : scutellum transversely triangular, punctured : 

 base of elytra as in G. humeralis^ the humeral angle still more 

 produced (but not strongly concave within the angle), sides 

 with a very distinct sinus behind the humeral angle ; disk 

 slightly roughened or rugulose, indistinctly (except at apex) 

 granulose, moderately punctured, obscurely foveate-punctured 

 between the costae (when viewed obliquely) ; cost® very feeble ; 

 expanded lateral margins wide (and concave) at the base, 

 gradually narrowed behind ; underside &c. as in C. humeralis. 



Length 6\- lines ; width of elytra across the middle 2|- lines. 



Hah. New Zealand. One example.
