1490 COLEOPTERA 



with the first joint thick but shorter than the second, 3-7 gradually 

 thickened ; club large, oblong, obliquely narrowed at one side ; the 

 apical joints small. 



Underside piceous. Metasternum short, with oblique, elevated 

 borders between the hind and middle coxae ; its middle portion, and 

 the basal ventral segment, much flattened or depressed, closely 

 punctured, the latter with very slender erect hairs; second segment, 

 and the sides of the first, with coarse scales, third and fourth each 

 with one row of similar scales, the fifth with smaller scales. The 

 pectoral canal with raised hind border. 



There is no scutellum. The front sides of the thorax are incurved 

 from above to the angles of the canal. Eyes large, hardly free, sub- 

 rotundate. 



Somewhat similar to No. 867 in form ; the thorax, however, is 

 not abruptly narrowed in front, and there are no crests. It is a very 

 distinct species. 



Length (rost. excl.), J; breadth, quite \ line. 



Maketu, Hunua Range. Two, found on the ground amongst 

 leaves. 



2571. A. allostethus, n.s. Variegate, squamosity greyish- 

 testaceous ; blackish, antennae and tarsi reddish, front of rostrum 

 piceous. 



This closely resembles A. aulacus ; the frontal portion of the 

 rostrum has deeper, closer, and more rugose punctures ; the thorax 

 is distinctly longer, more narrowed anteriorly, and it has a central 

 longitudinal line ; the elytra, though very similar, have more nume- 

 rous black and greyish spots ; the dark marks near the shoulders, as 

 well as those on the thorax, are similar ; the most important differ- 

 ences are to be seen underneath. 



The hind border of the pectoral canal is thicker. The mctaster- 

 num is without the oblique intercoxal elevations. The squamosity 

 is yellowish. The club is unsymmetrical also. 



Length (rost. excl.), f; breadth, line. 



Maketu. One, on the ground, amongst fallen leaves. 



2572. A. incultus, n.s. Broad, widest behind, the shoulders, 

 nearly equally narrowed towards both extremities ; opaque, squamo- 

 sity dense, rather small, oviform, depressed, mostly pale infuscate- 

 red, each side of the posterior declivity blackish, there are also dark 

 scale-like erect setae ; femora dark and opaque, tibiae obscure-red and 

 sparsely setose, antennae and tarsi reddish. 



Eostrum rather short, slightly pinched in near the eyes, broad, 

 dark, opaque, asperate, and squamose, there are, apparently, five 

 slender costae, the basal portion bears reddish scales. Thorax 

 almost as long as it is broad, much, but not suddenly, narrowed in 

 front, the sides in front of the middle appearing somewhat incurved ; 

 there are no crests, there is a row of coarse grey setae in front, it is 

 coarsely and closely punctured. Elytra cordiform, base slightly 

 sinuous and hardly at all broader than the thorax, the declivity
