Apion. | RHYNCHOPHORA. 165 
punctured and finely wrinkled between the eyes; rostrum cylindrical, 
rather long, curved, shining, finely and diffusely punctured, often with 
a small stria or fovea between the antenne, which are rather stout and 
are inserted at about the middle ; thorax conical, longer than broad, 
with close and rather strong punctuation, whieh is sometimes more or 
less confluent, and a small stria or fovea before scutellum which is often 
obsolete ; elytra rather broad, wider behind middle, with rather strong 
punctured striz, which are about as broad as the interstices, the latter 
being flat and shagreened; legs moderately long and stout. L. 
2-25 mm. 
Male with the rostrum shorter and more plainly punctured than in 
female, and with the anterior femora stouter. 
On Lotus corniculatus ; the larva feeds in the pods of the plant ; locally abundant 
and widely distributed throughout the greater part of the kingdom: it appears, 
however, to be commoner in the South of England, and to be somewhat rare in the 
midland and northern counties; Scotland, Solway, Tweed and Forth districts ; 
Ireland, Waterford, &c. 
This species somewhat resembles A. ononis, but is larger and more 
robust, with the pubescence less evident, and with a wider head and 
more conical thorax, which has the furrow before scutellum small and 
obsolete, and not continued for the whole length as in the latter species, 
A. seniculum, Kirby (tenue, Gyll., nec Kirby, pusillum, Steph.). 
One of our smallest species; narrow, dull black, clothed with rather 
thick greyish pubescence; head long, eyes slightly prominent ; rostrum 
moderately long, curved; thorax about as long as broad, feebly punctured, 
with a fovea at base ; elytra rather long, leaden black, with sides a little 
dilated, and with punctured striz which are distinct but not very deep, 
interstices about as broad as the striz, plainly shagreened; legs 
moderately long and stout. L. 13-1$ mm. 
Male with the rostrum shorter and more thickly pubescent than in 
emale. 
On Trifolium pratense and other species of Trifolium ; the larva has been observed 
in the stems; common and generally distributed from Yorkshire southwards ; less 
common further north; Scotland, rare, Solway and Forth districts ; Ireland, Water- 
ford and Armagh, and probably common. 
A. tenue, Kirby, nec Gyll. Very like the preceding in size and 
general appearance, but more slender and much more glabrous and 
shining, the pubescence being very scanty, and with the elytra evidently 
depressed on disc ; the vertex of the head is more plainly punctured, and 
the thorax is longer and more cylindrical with more sparing punctuation ; 
the elytra, moreover, are less acuminate at apex and the striz are stronger. 
L. 15-1} mm. 
On Melilotus officinaltés and Medicago sativa; the larva lives in the stems; not so 
common as the preceding but very widely distributed, especially in the London 
district and the South of England; Bristol; South Wales; Knowle, near Birming- 
ham; Trench Woods; Filey, Yorks; Manchester, general but rare; not recorded
