OF NEW ZEALAND. 1489 



Hostrum about as long as the thorax, rather broad, slightly nar- 

 rowed towards the centre, red, and finely sculptured, in front, the 

 basal portion with yellowish scales. Thorax truncate at the base, 

 gradually narrowed towards the front, without distinct punctures. 

 Elytra closely adapted to the thorax, very convex, abruptly curvedly 

 deflexed behind, widest near the middle, apparently without sculp- 

 ture. Legs densely clothed with fulvous hairs, and erect infuscate 

 setae, comparatively long and robust ; thighs not clavate ; anterior 

 tibiae incurved along the outside, with distinct terminal hooks ; tarsi 

 with first joint rather slender, second joint as long as broad, third a 

 good deal expanded and lobate, fourth elongate and slender. 



There is no scutellum. Eyesr&thei large, just free, subrotundate. 

 No ocular lobes. Antenna medially inserted ; scape short and thick, 

 much, but only gradually, incrassate ; funiculus elongate, first joint 

 stout, largest ; club ovate, apical joints short and pubescent. 



This should be placed near A. alpestris. It may be known by 

 the smooth shining surface, its quite uninterrupted outline, and dis- 

 tinct contrasts in coloration. It is not likely that these two species 

 will remain in Acalles.

Maketu, Hunua Eange. One, on the ground, amongst leaves. 



2570. A. aulacus, n.s. Convex, broad, ovate, without con- 

 spicuous inequalities of surface, piceous, antennae and tarsi red ; 

 densely covered with subdepressed, coarse, rounded scales, mostly 

 reddish-brown, blackish ones form two large elongate patches near 

 the base of the thorax, and small irregular spots on the elytra ; the 

 four hind tibiae are dark near the knees ; on the third and fourth 

 interstices of each elytron, in line with the hind thighs, there is a 

 distinct grey spot ; there are no erect setae. 



Hostrum about the length of the thorax, feebly narrowed towards 

 the middle, coarsely and rugosely punctured in front, squamose 

 behind. Thorax about as long as broad, its frontal half depressed 

 and obviously contracted, not abruptly so, however ; it is coarsely 

 and closely punctured ; the scales at the sides, and along the front 

 of the dark spots, are more erect than the others but do not form 

 crests. Elytra short, much rounded, base truncate and closely 

 applied to the thorax, of the same width there, much broader be- 

 hind the shoulders, so much curved as to be vertical behind; 

 the suture, at the base, is somewhat depressed, and has two small 

 black tubercles ; they are punctate-striate, the striae appear to be 

 deep, owing to the overlapping scales on the interstices, which are 

 rather broad ; there is a blackish spot near each shoulder. Legs 

 comparatively long and thick, the scales on the front femora are 

 longer than those on the others, these thighs are not clavate but 

 they are thick, and grooved below at the apex, the other femora are 

 grooved underneath ; anterior tibiae rather short, a little curved, 

 prominent at the knees, with moderate hooks ; tarsi with broadly- 

 expanded and lobate third joints.
