76 OOLEOPTERA. 



hli/tid sul)paViillol, <'it)ii;iat»', ohvioiisly liroadcr tliaii llioni.x, the shoulders 

 ii little elevated, apices broadly rounded or subtnincate. so that the last 

 dorsal segment is uncovered ; their punctation evidently closer and rather 

 finer than that of the thorax, and with numerous minute punctures inter- 

 posed ; they are very slightly impressed near the suture, and tliere seem a 

 little rugose. Legs simple, i)ul)esient. 



VndcrsiiU' nigro - aeneous, finely sculptured, and })ul)escent. The 4th 

 ventral segment is somewhat nu^dially al)l)reviated ; the r)th elongate, witli 

 a deep cuneiform impression, wiiich is wide.st heliintl. 



Feni. — Body rather broader, 5th segment conical and uniiiijjre8.sed. 



Var. A. — Thorax subcyaneous. 



Var. B. — Elytra of a reddi.sh-coppery hue. 



L. axyrochares most nearly reseml)les this species, which, however, is 

 relatively narrower, the elytra particularly : the thorax is more distinctly 

 punctured, the eyes are more ajiproximated. and the coloration is different. 



g . Length, 1| lines ; l)readth, % line. 



Mount Cook. A good series found f)y Mr. T. K. Cheeseman. 



3151. Luperus obscurus sp. nov. 



Oblong, moderately convex, nude above, shining, fuscous, legs and an- 

 tennae fusco-testaceous. 



Ilend nearly as broad as front of thorax. Antmnnc pubescent, stout, 

 2nd joint .shorter than 3rd, the following ones about equal. Thorax a third 

 broader than long, straight in front, the base slightly rounded and oblique 

 towards each side so that the posterior angles are not sharply defined, 

 anterior angles slightly thickened but not prominent, lateral margins 

 distinct, the sides a little rounded : its punctation very irregular, distinct 

 near the base and the middle, very much finer in front and Vtetween the 

 middle and sides. Scutdbim smooth. Elytra widely incurved at the base, 

 evidently broader than the thorax, slightly wider behind than at the base, 

 the shoulders obtusely prominent in Iront but not raised, apices obUquely 

 rounded and subtruncate so that the sculptured and pubescent pygidium 

 is exposed ; they are irregularly, distinctly, but not very closely punctured, 

 rather more distinctly near the extremity. Legs simple, pubescent. 



This is obviously different from />. chrrsnnani, and. indeed, from any of 

 our species. 



Vor. — Anterior angles of thorax not incrassate. riytra witli less-promi- 

 nent shoulders. 



9 . Lengtli. 1 J lines ; breadth, ^ line. 



Mount Cook. Two examples only. Mr. T. K. Checseman. 



3152. Luperus diversus sp. nov. 



Oblong, apparently glabrous, shining, obscure fusco-testaceous, the middle 

 of thorax irregularly dark fuscous, a broad ill-defined vitta near each side 

 of the elytra infuscate, as are also the last () anti'unal joints. 



Head, including the eyes, as broad as the front of the thorax. Ahtvnnaf 

 pubescent, their fth joint not as long as the preceding 2 combined. Thorax 

 l)roa(ler than it is long, truncate in front, the base obliquely rounded towards 

 the sides .so that its angles are ill defined though nearly rectangular, an- 

 terior angles not distinctly thickened, lateral margins fine and only a little 

 rounded ; the sui"face a])pears smooth, yet there are a few shallow punctures 

 near the base and some minute distant ones in front. Elytra oblong, 

 broader than thorax at the base, more .so behind, apices separately rounded
