OF NEW ZEALAND. 743 



obtuse angles, prolonged forwards ; its surface is a little uneven, closely 

 punctured, reddish, the yellow hairs usually forming a dorsal line. Scu- 

 tellnm small. Elylra oblong, wider than thorax, apex obtusely rounded; 

 each with a large compressed basal tubercle near the suture, a smaller 

 rounded one after the middle, and two contiguous ones on the summit of 

 the posterior declivity ; their surface is a little uneven, punctate-striate, 

 with variegate clothing and several blackish spots, most conspicuous near 

 the sides. Legs moderate, testaceous ; the middle of the femora and 

 tibiaj and the apex of the basal tarsal joints more or less piceous ; each 

 claw with a distinct tooth. 



The male is distinguished by the greater length of the antenna) and 

 two tubercles between their point of insertion ; the female (.^) is smaller, 

 and the club of the antenna; only extends beyond the hind-body ; in both 

 sexes the pygiduwi is but little exposed. Allied to A. discedetis, but with 

 the eyes slightly more notched. 



^. Length, if; breadth, % line. 



I have received three specimens from i\Ir. P. Stewart, of Wellington. 



1 318. A. nigrescens, n.s. Body pitchy-black, head and front of 

 thorax brown, legs testaceous si)olted with black, antenna) castaneous ; 

 clothed with grey and yellowish hairs. 



Rostrum about as broad but twice as long as the head, a little dilated 

 in front, punctate ; eyes rounded, emarginated in front, moderately j)ro- 

 minent. Anteimas as long as the body, slender, inserted in foveiform 

 scrobes at the sides, a little distance in front of the eyes ; their two basal 

 joints stout, the visible part of the first as long as the second; joints 3-8 

 decrease, each a little thickened at the end ; ninth elongate-triangular, 

 as long as the next two taken together. Prothorax a good deal broader 

 than long, punctate ; its carina distinct from the base, obtusely angulated 

 in the middle, oblique just beyond, from thence rather deeply sinuated 

 towards the sides, where it is bent forwards, the angle obtuse. Scu- 

 tellum small, whitish. Elytra oblong, slightly dilated behind, punctate- 

 striate, interstices finely punctured ; each with a large, somewhat com- 

 j)ressed basal tubercle near the suture, an obtuse oblong one behind the 

 middle, and two smaller contiguous ones behind ; the greyish clothing is 

 chiefly confined to the sides, the disc being nearly nude and glossy. 

 Legs moderately long; basal joint of the tarsi longer than the following 

 two ; third short, bilobed ; claws distinctly toothed. 



Somewhat similar to A. disccdens and its allies, but readily distin- 

 guished by the short thorax. When examined from the side, it will be 

 noticed that the elytra are gradually depressed from the median tubercles 

 to the shoulders. 



Length, i .\ lines; breadth,^. 



One indivitlual received from Mr. P. Stewart, of Wellington. 



1 3 19. A. torulOSUS, n.s. Fuscous, covered with grey and yellow- 

 ish hairs ; legs fusco-tcslaceous sjiotted with black, antennx' castaneous. 



Rostnun double the length and nearly as broad at the head, punctate, 

 reddish, covered with yellowish hairs, and bearing two inter-antcnnal 

 tubercles. Prothorax broader than long, closely punctured ; its carina 

 distinct from the base, angulated at the middle, obliquely but slightly 

 sinuated towards the sides, where it is obtusely bent forwards ; the surfiice 

 uneven, transversely depressed before and after the middle. Scutellum
