634 COLEOPTERA 



I found the two individuals now before me at Tairua. The species 

 may be at once identified by its short broad thorax, which is differently 

 formed from that of the two preceding species. 



nil. A. ni^ripes, n.s. Not unlike Z. thoradcus: the thorax 

 somewhat similar, but less transverse, more convex and regularly rounded 

 laterally, of a testaceous-yellow colour, with an almost smooth surface. 

 Its head is black, with more pronounced sculpture, the eyes truncated 

 inwardly and distinctly facetted. Anteuum and palpi black. Elytra 

 oblong, ratlier convex, parallel-sided, very little widened behind, a little 

 divergent near the apex, the apices almost obliquely truncated ; their 

 sculpture is rather finer and less rugose than usual, the intra-humeral 

 depressions are well-defined, and, the more or less obvious, sutural and 

 lateral depressions seen in the preceding species are, in this, entirely 

 absent ; the predominating colour is testaceous, but the base, suture, 

 and apical margins are smoky-brown. The legs are blackish, the two 

 hind pairs of tibitt* are distinctly hirsute and arcuated. 



Length, 2|- lines ; breadth, \\. 



Described from one example found at Parua, near Whangarei 

 Harbour. The insect, when set out and viewed laterally, is seen to be 

 more convex than usual, the basal portion of the elytra, particularly, is 

 more elevated. 



1 1 12. A. nigricans, n.s. Oblong, narrow, sub-depressed, sub-par- 

 allel, the elytra slightly wider behind than in front, where they are but 

 little broader than the thorax ; of a blackish colour, not much shining, 

 with the legs and antennse fuscous. Thorax transversely-quadrate, slightly 

 narrowed anteriorly, nearly straight laterally, apex sub-truncate; the base 

 with a somewhat sinuous outline, being a little truncated in the middle 

 with a slight sinuation at each side ; its front and hind angles are almost 

 rectangular ; the surface is a little uneven, there are some obsolete dis- 

 coidal impressions, and it bears shallow punctures. Scutellum rather 

 broad. Elytra narrow, sub-parallel, widest behind, depressed near the 

 shoulders and along the middle, and obtusely rounded behind ; their 

 sculpture is indistinct, consisting of broad, almost imperceptible longitu- 

 dinal elevations and shallow punctures, they are a little wrinkled near 

 the shoulders, and less obviously elsewhere. 



Legs moderately long, of normal structure, the tibiae clothed with 

 griseous hairs. The head is rather short, not deeply inserted ; the last 

 joint oi the pa/pi is small, eyes moderately coarsely granulated, antentm 

 long. The elytra are finely but distinctly margined at the base as well 

 as the sides. 



Length, 2\ lines ; breadth, f. 



I found one individual only at Tairua. The insect may be easily 

 recognised by its black colour, elongate outline, and subquadrate thorax. 



1 1 13. A. nitidicolle, n.s. Oblong, rather elongate, sub-depres- 

 sed ; head and thorax shining bronzy-brown, elytra testaceous with vein- 

 like reticulations, legs testaceous, antennae infuscate.
