Apion.] RHTXCHOPHORA. 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 antennas, which are rather stout and 

 are inserted at about the middle ; thorax conical, longer than broad, 

 with close and rather strong punctuation, which 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 striae, which are about as broad as the interstice.*, the latter 

 being flat and shagreened ; legs moderately long and stout. L. 

 2-2', mm. 



Male with the rostrum shorter and more plainly punctured than in 

 female, and with the anterior femora stouter. 



On Lotus eorniculatvs ; 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, Sol way, 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., nee 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 striae which are distinct but not very deep, 

 interstices about as broad as the striae, plainly shagreened; legs 

 moderately long and stout. L. 1^-1 f 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, Sol way and Forth districts; Ireland, Water- 

 ford and Armagh, and probably common. 



A. tenue, Kirby, nee 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 striae are stronger. 

 L. H-lf mm. 



< )n Melilotus officinalis aud Hedicago satira ; the larva lives in the stems ; not rn 

 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, generjl but rare ; not recorded
