OF NEW ZEALAND. 1385 



Acalles (Gen., p. 488). 



2416. A. mimus, n.s. Convex, ovate, contracted medially; 

 piceous, thickly covered with pale reddish-brown, black, and greyish 

 scales, and erect squamiform setae ; antennae and tarsi red. 



Hostrum finely punctured in front, with testaceous scales behind, 

 it is as long as the thorax, and is narrower near the middle than it 

 is elsewhere. The scrobe begins at the middle and reaches the front 

 and lower part of the eye. Antenna with fine hairs ; funiculus 

 longer than the scape, its basal joint rather longer and much thicker 

 than the second, joints 3-7 increase in bulk so that the seventh is 

 almost as broad as the base of the club, which is large and ovate. 

 Thorax about as long as it is broad, the frontal half narrower and 

 more depressed than the basal ; at the middle of the base the 

 squamosity is blackish, there are some coarse dark setae ; on the 

 middle there are two small crests, and, in line with these, at each 

 side there is a smaller one, the apex is not crested. Scutellum in- 

 visible. Elytra of the same width as the thorax at the base, much 

 wider just before the middle, gradually narrowed behind that point ; 

 they are rather suddenly raised from the base backwards, so as to 

 seem very convex, the posterior portion appears long and narrow ; 

 the sculpture is hidden, but apparently consists of series of punctures ; 

 on top of the hind slope there are two large squamose prominences, 

 there are two small crests on the middle, and two others further 

 forward and nearer the suture, besides some minute ones near the 

 sides and on the declivity itself. The legs bear coarse scale-like 

 setae. 



Closely resembles A. decemcristatus : in that species, however, 

 the posterior declivity presents a flat face which is densely covered 

 with depressed, pale, greyish-yellow scales, forming a conspicuous 

 appearance ; in this species there are some scattered pitchy setae. 



VAB. Thorax darker, the squamosity on the middle of the 

 elytra, for the most part, greyish, there are four black spots in place 

 of the median crests, and, on the suture, in front of the posterior 

 crests, there is an obtuse tuft. 



Length (rost. excl.), 1^ lines; breadth, nearly -| line. 



Moeraki. Four examples from Mr. Sandager. 



OBS. From the same source I have some specimens of No. 1427 

 (A. triangulatus) , having a triangular patch on the middle of the 

 elytra ; this is sometimes quite pale, in other cases it is nearly black. 

 The type, found near Wellington, was therefore in an imperfect 

 condition . 



2417. A. lepirhinus, w.s. Convex, rather narrow, opaque, 

 piceous, antennae and tarsi ferruginous ; squamosity dense, depressed 

 as well as ereco, mostly piceous ; on top of the hind declivity are 

 two tawny crests, some grey scales and coarse setae are visible near 

 the middle of the elytra and along the sides of the thorax ; the legs 

 bear coarse scale-like setae, most of which are greyish; and the 

 rostrum, almost to its apex, is covered with short, erect, pallid scales,
