Male with the scape of the antenne clavate, much dilated at apex, 
funiculus with the first joint small, and the second and third very broad

Marshy places; on Polygonum hydropiper, &e.; local; London district, rather 
common and generally distributed ; Birchington ; Deal ; Dover ; Hastings ; Arundel ; 
Brighton ; Portsmouth; Devonshire; Littlington, Cambridge; Huntingdonshire ; 
Knowle, near Birmingham; I know of no record further north than Hunstanton, 
Norfolk, where I have taken it sparingly on the side of a brook towards Heacham.

glabrous ; head rather broad, somewhat obsoletely punctured in front; 
thorax subcylindrical, with the sides rounded in middle, closely and 
rather strongly punctured, with an indistinct channel before base ; elytra 
comparatively short, with rather fine punctured striz, shoulders strongly 
prominent ; femora and basal half of tibie red, anterior tibiz often

elytra long, oblong oval, with punctured striz ; femora, except extreme 
apex, and anterior coxe, red ; anterior tibie mostly red, intermediate 
and posterior pairs with a broader or narrower red ring before base ; the 
species is allied to A. apricans, from which it may be known by having 
the rostrum longer and much more curved, especially in the female, the
