390 COLEOPTERA 



The species may be at once recognized by the singular form of the base 

 of the thorax. 



I have received one individual from Professor Hutton. 



693. A. zealandicum, Bates; Ann. Mag. Nat. Hist., February, 

 1874. Oblong, sub-parallel, attenuate behind, depressed; bronzed- 

 brown, more or less metallic. Head short, immersed up to the eyes in 

 the prothorax, somewhat rounded in front ; epistoma very short, convex, 

 distinctly emarginate in front, the suture more or less distinctly marked, 

 arcuate ; one or more impressions between the eyes ; rather strongly 

 and somewhat irregularly punctured and rugose ; labrum prominent, 

 transverse ; angles strongly rounded, notched at apex ; antennce mode- 

 rate, a little longer in male than in female, perfoliate (distinctly so in 

 male), gradually thicker, and a little compressed outwardly ; the joints 

 obconic, all longer than wide, three shorter than four and five united, 

 the last largest of all, obliquely rounded at apex ; prothorax sub-quad- 

 rate, wider than long ; sides anteriorly moderately incurved, posteriorly 

 sub-parallel, or very slightly sinuously contracted ; apex arcuate emar- 

 ginate, and distinctly margined throughout ; front angles a little depres- 

 sed, obtuse ; base closely applied to and overlapping the base of the 

 elytra, strongly emarginate at the middle, the hind angles obtuse ; more 

 or less finely and somewhat irregularly punctured, more or less dis- 

 tinctly wrinkled at the sides and at the hind angles, distinctly (especially 

 at the sides) but very finely pubescent ; the whole surface more or less 

 uneven by numerous irregular foveate impressions, the most constant 

 being the rounded fovea at each side of the middle at the basal margin ; 

 scutellum rather large, convex, punctured, transversely curvilinearly trian- 

 gular ; elytra but little broader at base than the base of prothorax, nar- 

 rowed behind, finely pubescent, with numerous striae, these sometimes a 

 little irregular, more or less finely impressed, but very rarely (in but one 

 out of the ten examples before me) distinctly punctured ; the intervals 

 (except at the apex) flat, very finely and closely muricate-punctate, here 

 and there interrupted by irregular transverse impressions, which some- 

 times assume the form of rounded fovese ; winder-side bronzed-brown, 

 finely pubescent ; prosternum slightly compressed in front of the coxse, 

 its process rather narrow, convex, finely margined at the sides, very 

 obtuse and not produced behind ; intercoxal process wide, sub-truncate 

 at apex ; legs reddish-brown ; tarsi and antennae ferruginous ; the four 

 front tarsi distinctly more expanded in male than female ; inner edge of 

 hind tibia fringed with longish hairs in the male. 



Length, 3^-4! lines. 



New Zealand. Ten examples. 



694. A. thoraciCTim, Bates. Two specimens with the above 

 label were recently sent me by Mr. C. M. Wakefield, but I do not know 

 whether the species has been described. 



The insect is of an elongate form, somewhat similar to A. zealandi- 

 but may be readily distinguished from its allies by the shape of the
