374 COLEOPTERA 



tulate ; 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 humeralis, and slightly con- 

 vergent or directed inwardly ; apex deeply emarginate, front angles sub- 

 acute, slightly convergent ; expanded lateral margins moderately wide, 

 scarcely concave, the edges finely and almost uniformly thickened ; a 

 rather slight sublunate 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 C. humeralis, the humeral angle still more produced 

 (but not strongly concave within the angle), sides with a very distinct 

 sinus behind the humeral angle ; disc slightly roughened or rugulose, 

 indistinctly (except at apex) granulose, moderately punctured, obscurely 

 foveate-punctured between the costae (when viewed obliquely) ; costae 

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

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



Length, 5 \ lines ; width of elytra across the middle, 2 lines. 



New Zealand. One example. 



The punctation on the head and on the sides of the prothorax is 

 more crowded, and the interstices more closely and distinctly punctulate 

 than in C. humeralis ; the sides of the thorax are distinctly incurved at 

 the hind angles ; the punctation on the elytra is less defined ; and the 

 form is elongate-oval. 



672. C. brevipenniS, Bates; Ann. Mag. Nat. Hist., Dec., 1873. 

 Smaller, and of a more briefly oval form, than any other species in the 

 genus. Black, usually most nitid on the prothorax, the elytra frequently 

 of an obscure purplish-brown hue ; sometimes the entire upper surface 

 is of a decided reddish-brown colour. Head and prothorax finely and 

 closely punctured, the punctation very dense (and frequently finely 

 reticulately rugose) on the former and on the sides of the latter ; the 

 interstices more or less distinctly minutely punctulate : prothorax trans- 

 verse, apex deeply emarginate ; front angles prominent, more or less 

 acute, usually directed forwards, sometimes slightly convergent ; sides 

 anteriorly very gradually narrowed from the middle (sometimes from 

 behind the middle), posteriorly subparallel, or slightly incurved (in one 

 example they are distinctly excurved at the hind angles which are con- 

 sequently somewhat outwardly directed), hind angles more or less 

 produced, acute, directed backwards; lateral margins moderately ex- 

 panded, more or less concave ; three more or less distinct impressions 

 at the base, and sometimes two indistinct foveate impressions on the 

 middle, at each side of the median line : elytra short, moderately con- 

 vex, base feebly sinuous ; humeral angle not distinctly prominent, as in 

 C. humeralis and thoracica ; sides subparallel or slightly rounded, not 

 sinuous behind the humeral angle; expanded lateral margins rather 

 broad at the base, narrowed behind, more or less distinctly extending 

 to the apex, strongly concave at the base (especially within the humeral 

 angle) as in C. humeralis ; punctation, &c., almost as in C. thoracica, but 

 (especially at the sides and apex) the surface is slightly more roughened,
