OF NEW ZEALAND. 1159 



Head irregular!}', rugosely, but not deeply punctured. Thorax 

 about one-third broader than long, apex widely incurved, the base 

 not so deeply ; its sides almost regularly rounded, a little sinuously 

 narrowed towards the base, posterior angles rectangular, resting on 

 the elytra ; there is a feeble dorsal groove, the surface is moderately 

 finely and closely punctured, and there are two shallow basal im- 

 pressions. Scutcllam short and broad. Elytra broader than the 

 thorax at the base, widest near the hind thighs ; their surface not 

 at all uneven, finely and closely punctate ; each elytron with two 

 series of rather fine closely-placed punctures near the suture, these 

 do not form striae, other irregular lines of rather fine punctures en- 

 close oval or elongate spaces, none of which are raised. Tihicn 

 curved externally. 



A. nigrituluvi is narrower; the elytra, behind the shoulders, are 

 somewhat incurved ; the sculpture is coarser, and the surface more 

 uneven, though not to the same extent as in A. hullatus. These 

 two are its nearest allies, from each of which this species may be 

 distinguished by the larger size, broad form, and comparatively 

 smooth surface. 



Obs. — A variety of A. nigritulum has been found by Mr. Suter 

 on Mount Cook in which the areas enclosed by the fine serial punc- 

 tures of the elytra are, for the most part, linear, but I cannot 

 separate it from my typical specimen in a satisfactory way at 

 present.

Body elongate, subdepressed. Head transversely quadrate ; epi- 

 storne broadly rounded in front ; labrum prominent, truncate in 

 front. Eyci small, sometimes very small, coarsely facetted, trans- 

 versely oval, placed at the sides of the head just free from the 

 thoracic angles. Anteniur inserted in front of, but on a lower plane 

 than, the eyes ; most of the basal joint conceciled above by the anten- 

 nary orbits ; second joint scarcely longer than fourth ; third joint 

 nearly as long as the following .three taken together ; ninth and 

 tenth rather larger than eighth ; eleventh largest, broadly ovate. 

 Thorax closely adapted to elytra, longer than broad, narrowed be- 

 hind, rounded towards the front, posterior angles rectangular, the 

 anterior a little prominent. Scutellmn YQvy short and broad. Elytra 

 rather wider than thorax at base, humeral angles small but promi- 

 nent, sides subparallel, pleurae inflexed; cpipleura"- extremely narrow, 

 absent in fact. Prostcnium emarginate in front ; coxa; not prominent, 

 moderately widely separated. Legs simple ; tarsi pilose underneath, 

 narrow ; basal joint of anterior rather short, 2-4 transverse, fifth 

 elongate, the posterior with a rather short basal joint, second and 

 third transverse, fourth eloncrate.
