150 RHYNCHOPHORA. [Apion. 



sometimes rather rugosely punctured, with a distinct channel at base ; 

 the elytra are elongate ovate, with moderately strong punctured striae. 

 L. lf-2 mm. 



On white clover (Trifolium repens), Spircea, &c. : common and generally distri- 

 buted throughout the kingdom ; it extends over Europe and Northern Asia. 



I have adopted Bedel's name for this species, as the common name A. 

 JJavipes has been applied to several insects by different authors, and it 

 does not seem at all clear to what species the original type must be 

 assigned ; it is better therefore to adopt an entirely new name. 



A. nigritarse, Kirby. Smaller than the preceding from which it 

 may at once be known by the more finely punctured and smoother thorax, 

 and by the fact that the male has the anterior half of the rostrum yellow- 

 red ; the anterior coxae are red in both sexes, and the antennae are reddish- 

 yellow except the club, whereas in A. dichroum the anterior coxae are 

 black in the female, and the apical half of the funiculus of the antennas 

 is black in both sexes. L. \\ mm. 



On various species of Trifolium, and also on other low plants ; common and gen- 

 erally distributed throughout England from the Manchester and Liverpool district 

 southwards; recorded by Bold as not common in the Northumberland and Durham 

 district, and by Dr. Sharp as occurring only in the Solway district of Scotland ; Ire- 

 l;ind, Dublin, &c. ; the larva of the clover-feeding species appear to be almost always 

 found in the flower-heads. 



The A. Waterhousei of Boheman is, according to Walton, a variety of 

 the female of this species with the tibiae obscurely testaceous. 



GROUP 722. 



The who?e of the species in the remaining groups have the "body Hack 

 or metallic with the legs entirely dark (except A. annulipes, which has a 

 testaceous ring at the base of the tibice in male, A. flavimanum which has 

 the base of the tibiae yellow-brown in both sexes, the colour being often 

 obscure, and A. filirostre which sometimes has a testaceous ring at the 

 apex of the anterior femora) ; the chief distinguishing characters will be 

 found in the table of species (pp. 134 et seqq.), 



GHOUP 7. 



Rather small narrow species, with the forehead marked ivith two dis- 

 tinct furrows in the fcrm of a V (on Corynibiferae). 



A. confluens, Kirby. Kather narrow, black, somewhat shining, 

 clothed with distinct but fine and sparse pubescence ; head almost as 

 broad as the anterior margin of thorax, finely shagreened, rostrum 

 slightly curved, aboxit as long as head and thorax, antennas rather stout, 

 inserted near b;ise of rostrum ; thorax almost cylindrical, a little longer 

 than broad, sparingly and finely punctured with a small fovea at base ;
