144 RHYNCHOPHORA. [Apion. 
in front than behind, very finely and closely punctured ; elytra not very 
convex, crenate-striate, with narrow, somewhat raised, interstices; legs 
robust; the species may be known by its shape and by having the 
rostrum nearly straight and much longer in the female than in the male. 
L. 23-31 mm. 
On Rumezx acetosella ; according to M. C. Brisout the larva forms a gall at the 
roots of the plant ; also on Teucrium scorodonia: in sandy places; rare; Reigate 
(Champion) ; Esher (in some numbers (Champion) ); Weybridge on Agrimonia 
eupatoria (Power); Horsell (Power); Barmouth (Blatch) ; London and Yorkshire 
(Stephens). 
Group 5. 
Upper surface black ; legs wholly or in part red ; pubescence distinct 
at all events on under-side in male. 
A. pallipes, Kirby (geniculatum, Germ.). Oblong, sub-parallel, 
dull black, clothed with distinct and very evident whitish pubescence, 
which is, however, exsily abraded ; head short and broad, rather strongly 
punctured, with one stria between the eyes, which is, however, often 
obsolete, eyes prominent ; rostrum scarcely as long as head and thorax, 
curved, a little thickened at base, finely punctured ; antennz inserted 
near base, reddish-testaceous, with the club usually darker; thorax 
scarcely longer than broad, slightly constricted in front, with the sides 
sub-parallel, finely and closely punctured; scutellum rather large, sub- 
cordiform ; elytra oblong-oval, with large punctured strix, interstices 
scarcely broader than the striz, base of the third a little dilated and 
thickly pubescent ; legs testaceous with the tarsi and trochanters, and 
usually the apex of tibiz, and the knees, dark. L. 2-25 mm. 
Male with the rostrum stouter and duller, pubescent, and more 
evidently punctured; in the female the rostrum is longer and smoother 
and more plainly curved. 
On Mercurialis perennis and Allium, especially in chalky districts ; very local, but 
not uncommon where it occurs ; London district, not uncommon, Caterham, Mickle- 
ham, Birch Wood, Sevenoaks, St. Mary Cray, Dorking, Shirley, Birdbrook (Essex) ; 
Ditchingham, Suffolk; Birchington; St. Leonards Forest; Arundel; Bath; 
Robins Wood, Repton; Yorkshire; Bowden, near Manchester ; Northumberland and 
Durham district, rare; Scotland, very local, on Alliwm, Forth district; abundant at 
Eskbank, May 18, 1865 (Sharp). 
A. semivittatum, Gyll. (Germari, Walt.). Closely allied to the 
preceding, but more convex, with thicker and whiter pubescence, and 
usually with a distinct bronze reflection ; the rostrum is shorter and the 
thorax is more rounded at the sides; the elytra are proportionally 
broader, with the shoulders more marked, and there is often a denuded 
fascia on their disc; the club of the antenne is rarely infuscate, and the 
insect may easily be distinguished by having the tarsi and trochanters 
red. L. 1$-2} mm. 
On Mercurialis annua in September and October; the larva lives in the knots of
