Apion. | RHYNCHOPHORA. 151 
elytra leaden, not very convex, with fine and not deep punctured stria, 
and broad flat interstices ; legs rather stout. L. 1{-2 mm. 
Male with the rostrum shorter and the head broader, and the first 
joint of the posterior tarsi armed with a small spine beneath. 
Chiefly on Matricaria chamomilla, but occasionally on Chrysanthemum leucan- 
themum ; locally common; Mickleham, Egham and Gomshall, Surrey ; Lee, Esher, 
Birch Wood, Chatham, Sheerness, Erith, Belvedere, Dartford, &c.; Deal; 
Arundel; Brighton; Portsmouth; Isle of Wight; Devon; St. Faith’s, Norwich; 
Lowestoft ; Heysham, near Lancaster ; Ireland, Armagh (Johnson), 
A. stolidum, Germ. This species is very closely allied to the pre- 
ceding, and has by many authors been considered merely a variety ; it 
may, however, be known by the stronger strie of the elytra and con- 
sequently narrower interstices ; the rostrum is a little longer and more 
curved, the frontal impression is stronger, and the thorax is broader ; the 
general form is said to be shorter, but intermediate specimens occur ; the 
pubescence also is less evident. Tl. 15-1? mm. 
On Chrysanthemum leucanthemum (Ox-eye Daisy) and not on Matricaria; not 
common, or rather very local; Mickleham, Hammersmith, Birch Wood, Caterham, 
Sheerness, Weybridge, Horsell, Barking; Bushey, Herts; Birchington; Sussex ; 
Isle of Wight; Blackpool (Chappell) ; Scotland, rare, Solway district only.
