 furnished with white hairs ; head rather broad, eyes somewhat prominent ; 

 rostrum very variable in length in the sexes ; antennae inserted behind

 narrowed in front, coarsely punctured, with a small fovea before scutellum, 

 which is rather large ; elytra moderately long, a little dilated behind 

 middle, produced at apex in female, with the shoulders well marked, and 

 with broad strongly punctured striae, interstices narrow, subcarinate ; 

 legs black, moderately long. L. 2 mm. 



Male with the rostrum scarcely longer than the thorax, pubescent ; 

 antennae inserted a little behind middle of rostrum ; posterior tibiae 

 terminating in a distinct hook.

 plainly curved, more shining ; antennae inserted at some distance behind

 subparallel, moderately strongly punctured, with a small short fovea 

 before scutellum, which is small; elytra oblong, slightly depressed 

 towards base, with well marked shoulders, and with much finer striae 

 and broader interstices than in the preceding species, the latter being 

 wide, flat and very plainly shagreened, whereas in A. simile they are 

 scarcely as broad as the striae and are convex: legs black, moderately
