Black, with dense grey sealing ; the pro-thorax with a 

 brown stripe on each side and a narrow brown central line ; 

 elytra variegated with brown dorsally and with a more 

 distinct angulated brown marking behind the middle, followed 

 by a broad pale oblique band. 



Rostrum about as broad as long, almost parallel-sided and 

 directed downwards, the raised dorsal area also parallel- 

 sided and without any distinct anterior impression. Pro- 

 thorax about as long as broad, much narrower than the etytra 

 at the base, and only slightly narrowed in front, the sides 

 being almost straight, the dorsal anterior margin subtrun- 

 cate, the ocular lobes well developed ; the upper surface with 

 the sculpturing hidden by the scaling and set with very short 

 suberect setae. Elytra with distinct striae, but with the 

 punctures hidden by the scaling, the intervals convex and 

 with rows of erect scale-like setae. 



Long. 5j lat. 2^ mm. 



United Provinces : Dehra Dun (A. M. Littlewood). 



Mr. Stebbing states that the species was found in the 

 rotting bark of Mallotus philippinensis. 



In A. poricollis, Boh., the rostrum is porrect and narrowed 

 in front, the prothorax is broadly dilated behind and the sides 

 are angulated near the base, and the setae on the elytra are 

 recumbent and inconspicuous. Further, the scale-structure 

 is quite distinct : in A. subrecticollis the scales are flake-like, 

 fiat or slightly concave, strongly fluted, and more or less 

 regularly imbricated ; whereas in A. poricollis they are 

 somewhat bead-like, convex, indistinctly fluted, and scarcely 

 overlapping.

 fortiter punctato ; prothorace subconico, quam latitudine basali 

 vix breviore, lateribus fere rectis, aequaliter granulato, antice 

 rugoso ; elytris prothorace multo latioribus, humeris prominenti- 

 bus, lateribus subparallelis, seriatim fossulatis, subclathratis, inter-

Head closely punctate, with a frontal fovea. Rostrum
