24 COLEOPTERA 



50. A. SUbmetalliCUS, White; Voy. Er. Terr., Ins., p. 2. 

 (Colpodes.) Bronzy brown; thorax with the side margins yellowish; 

 the side margins of elytra very slightly yellow. Head in front, with the 

 sides with two deepish longitudinal impressions ; the edge slightly 

 recurved (of thorax, T.B.), scarcely grooved in the middle; elytra with 

 straight grooves not punctured ; the second groove (from the suture), 

 near the end with a transverse very short impressed line on the outside : 

 near the margin a row of impressed points, closest near the end ; an 

 impressed point near the end of the seventh stria ; legs yellowish ; 

 antennae brownish ; under side of abdomen greenish. 



Length, 4f lines. 



NOTE. A widely-distributed species ; the thorax is rather small, 

 relatively, to the wide oblong elytra. The fourth joint of the anterior 

 tarsi is rather triangular and emarginate. 



51. A. SUborbithorax, n.s. Colour pitchy black, head 

 and thorax shining, elytra rather dull, antennae, palpi and legs red- 

 dish. Head with two ill-defined frontal groves ; lab rum emarginate and 

 hispid. Thorax about as long as broad, with explanated and reflexed 

 margins ; the sides regularly rounded, indistinctly narrowed behind, the 

 front angles obtusely rounded, the posterior obsolete, apex slightly emar- 

 ginate, base truncate; the disc is rather convex, with an impressed 

 dorsal line, and a broad, shallow, irregularly curved groove between the 

 marginal channel and disc, the base is broadly depressed near the hind 

 angles ; there is a curved impression near the front, and another near 

 the scutellum, both of which are scored with fine longitudinal lines, the 

 rest of the surface with some transverse aciculate impressions. Elytra 

 broadly oval, not greatly wider than thorax, the base sinuous, with an 

 oblique sinuation near the apex ; each elytron bears nine impunctate 

 striae, the two outer ill-defined, the third and fourth, fifth and sixth, 

 unite before reaching the apex ; the interstices are rather broad, slightly 

 convex, and the marginal ones bear a row of large, but feebly impressed 

 punctures. The tarsi are hispid beneath, with the fourth joint of the 

 front pair sub-cordate, the two hind pair are feebly grooved above, and 

 all the joints have a piceous apical spot. The antennal joints 4-11, 

 with yellow pubescence. 



Length, 5! lines. 



I found my specimen on Mount Manaia, near Whangarei Harbour. 



52. A. perrugithorax, n.s. This species very much re- 

 resembles A. suborbithorax, but it has a shorter head, which is more or 

 less rugose, and the thorax, though nearly the same, approaches the 

 cordate form ; the apex being rather deeply marginate, the sides rounded, 

 but obliquely narrowed behind, with more distinct hind angles ; the disc 

 is sub-depressed, with impressions as in the preceding one, and strongly 

 rugose. The elytra do not differ materially from those of the preceding 

 species, but the marginal punctation is more obvious, and they are 

 indistinctly rugose towards the tip. The structure of the legs is alike in 

 both species, but, in this the femora are more or less rugose, and the
