8oo COLEOPTERA 



testaceous scales, and erect similarly - coloured ones form two 

 crests on its summit. Legs stout, somewhat rufescent, clothed 

 with upright grey scales. Antenna stout, of the orthodox pattern, 

 arising from the middle of the beak. 



In some respects resembles a small and narrow A. erroneus, but 

 more nearly allied to A. deccmcristatus in the form of the elytra. 

 The green scales on the front of the thorax form a distinguishing 

 feature.

One of my Parua captures. 



1426. A. decemcristatus, w.s. Fuscous, closely covered with 

 testaceous and blackish scales, with erect ones of the former colour 

 on the elevated parts forming ten tufts, four on the thorax, two 

 apical, the others dorsal, two close together near the middle of each 

 elytron, and two more conspicuous ones on the top of the hind 

 slope ; the blackish scales are congregated on the base and the sides 

 of the apex, whilst the hind slope, along the suture, is densely 

 covered with pallid squamosity ; the antennae and tarsi are red. 



Bostrum rather short and stout, barely as long as thorax, linearly 

 punctate in front, scaly behind. Prothorax longer than broad, sub- 

 conical, transversely depressed near the front, its sculpture imper- 

 ceptible. Elytra triangularly obovate, not obviously wider at the 

 base than at the thorax, broadly dilated before the middle, greatly' 

 narrowed and deflexed posteriorly, rather suddenly elevated behind 

 their base, the space betvv-een the crests nearly plane ; their sculp- 

 ture invisilDle. Legs robust, covered with fuscous scales and coarse 

 setae. Antenna implanted at the middle of the snout, rather short ; 

 second joint of the funicle nearly as long as, but much more slender 

 than, the first. 



Can only be compared with the following species {A. iriangu- 

 latus), but the elytra are far more obliquely narrowed in front, 

 more strongly elevated, and the thorax is narrower and less 

 conical. 



My specimen is unique. Collected by Mr. P. Stew art- Sandager 

 near Port Nicholson. 



1427. A. triangulatus, ii-s. Convex, uneven, squamose, 

 variegate ; fuscous, antennae and tarsi red. 



Bostrum black, its punctation linea^r, smooth but not costate 

 along the middle, its basal portion covered with yellowish scales; 

 it is arched and sub-parallel. Antcnnce inserted at the middle, 

 sparsely pilose ; first joint of the funiculus obcoiiical, and longer 

 than the following ones ; club oval, compact. Prothorax a little 

 longer than broad, conical, somewhat depressed anteriorly ; covered 

 with flattened fuscous and testaceous scales, and many erect and 

 more obscurely - coloured scales and setae near the sides and 

 apex. Scuiellum distinct, squamose. Elytra sub-triangular, a little 

 wider at base than the thorax, broadest just behind the shoulders, 

 considerably attenuated and suddenly depressed apically ; sub- 

 punctate-striate, their squamosity variegated, reddish-brown, black-
