160 RHYNCHOPHORA. [ Apion. 
shining band adjoining the thorax; rostrum curved, longer than head 
and thorax, dull and punctured behind, smooth and shining in front; 
antenne inserted near middle of rostrum, rather long.; thorax about as 
long as broad, a little narrower in front than behind, with coarse and 
often more or less confluent punctuation, and a distinct central channel, 
which is sometimes entire, and sometimes abbreviated towards apex and 
base ; scutellum small; elytra pyriform, a little broader at base than base 
of thorax and gradually and strongly dilated behind, the greatest breadth 
being almost at apex, shoulders not marked ; strize broad and deep and 
strongly punctured, interstices somewhat convex, about as broad as the 
strie, shagreened ; legs black, rather long and stout. L. 25-35 mm. 
Male with the rostrum slightly thicker and shorter than in female. 
On Ulex Europeus, Sarothamnus scoparius, &c.; common and generally distri- 
buted througbout the kingdom. 
A. immune, Kirby (befule, Gyll.). This species very closely re- 
sembles the preceding, with which it is often confused, but it is, on 
the average, smaller, and may be known by having the head distinctly 
striated between the eyes, and the vertex very coarsely punctured where 
it is adjacent to thorax, the corresponding space in A. striatum being, as 
Walton points out, smooth and shining ; the thorax is rather longer and 
has no central furrow in middle, but a small stria or fovea before scutel- 
lum, which is sometimes obsolete or wanting; the striz of the elytra are 
deep with the punctures somewhat stronger than in A. striatum, and 
placed more widely apart, but this latter character is not a very depend- 
able one. L. 2-2? mm.

Grove 18. 
Black or metallic, pubescent, species, with the rostrum curved and 
usually long and slender (on low Leguminose, chiefly Lathyrus, Vicia, 
§c., with the exception of A. Scutellare which oceurs on Ulex). 
A. ononis, Kirby. (ononidis, Bedel, &c., nee Gyll.). Dull black, 
thickly clothed with grey pubescence; head long, somewhat enlarged 
behind, coarsely and rugosely punctured, and striated between the 
eyes, which are large and slightly projecting; rostrum rather stout, 
curved, strongly and closely punctured, underside furnished along 
its whole leneth with small hairs visible if viewed sideways (a 
distinctive character pointed out by M. Bedel) ; antenne black, rather 
long and slender, inserted near middle; thorax about as long as broad, 
slightly narrowed in front, closely and coarsely punctured, with a tine
