OF NEW ZEALAND. 1261 



Closely related to A. crassus, No. 983. A}itcnncB with the second 

 joint thicker and rather shorter. Elytra very similar, the sculp- 

 ture, however, more obvious, considering the small size of the insect, 

 it being little more than half the bulk of the other. 



Length, nearly 1 ; breadth, f line. 



Paparoa, near Howick. One example. 



222'2. A. fungicola, '^i'- Cour^o-', subopaque ; head and thorax 

 nigro-piceous, frontal portion of the latter rufescent ; elytra of a 

 chestnut colour ; antennae fuscous, but with their two basal joints 

 fulvescent ; legs reddish-brown, the knees and tarsi paler. 



Head and rostrum closely and comparatively* coarsely punc- 

 tured. Thorax with similar sculpture, broader than long, bearing 

 flavous pubescence. Scutclluvi indistinct. Ehjtra evenly convex, 

 without distinct inequalities, rather regularly punctured, the punc- 

 tures forming strige ; interstices rather closely punctate. 



Underside and pygidium blackish. 



This is congeneric with A. crassus. It is differently coloured, 

 and the yellowish pubescence is evenly distributed instead of caus- 

 ing spots ; the thorax is much shorter, and its carina, owing to the 

 absence of the elytral margin or thickening of the base, does not seem 

 so closely fitted to the hind-body. 



Length, 1 ; breadth, ^ line. 



Five examples, found amongst fungi on the side of a log near 

 Howick. The insect possesses considerable saltatorial powers. 



2223. A. thoracicus, n-^- Compact, very convex, suboblong, 

 slightly shining, greyish-black ; legs rufo-fuscous ; tarsi and antenna 

 paler, the two basal joints of the latter fulvescent ; clothing greyish. 



This little creature much resembles A. )ianus, but has the head 

 less rostrate. It is remarkable on account of the very large tliorax, 

 which, indeed, just about equals the hind-body in bulk ; its punc- 

 tuation is close, rather coarse, comparatively, and appearing trans- 

 versely rugose ; the middle of the disc less elevated than in that 

 species, and wdth the carina more strongly sinuated on either side of 

 the middle. Elytra densely sculptured, and with very irregular 

 series of moderately large punctures ; each elytron with three large, 

 but not much elevated, rather rotundate prominences disposed in a 

 row. 



The posterior angles formed by the carina do not embrace the 

 shoulders to the same extent they do in A. nanus, but in other 

 respects the structural characters are similar. 



Length, -| ; breadth, nearly f line. 



Mokohinou Island. One individual, found by Mr. Sandager. 



2224. A. sandageri, n.s. Variegate, pale - castaneous ; the 

 sides, undersurface, an oblique vitta on each elytron extending from 

 the base, midway between the scutellum and shoulder, to the hind 

 thighs, sometimes interruptedly prolonged round the apex, and a 

 broad curvate fascia behind these thighs, dark-fuscous or blackish ;
