294 RHYNCHOPHORA. [Acahjptns. 



ACAXiYPTVS, Schonher-r. 



This genus contains only one species which, however, has a very wide 

 range, being found in North America, Northern Asia and Northern and 

 Central Europe ; it is very rare in Britain. 



A. carpini, F. (v. rufipennis, Gyll.). Oval, subdepressed, clothed 

 with shining silvery white pubescence, colour variable, sometimes almost 

 black, but usually dark with the elytra testaceous, at least in part, the 

 portions about scutellum and along suture being more or less fuscous ; 

 antennae and legs always red or testaceous, the former eleven-jointed 

 with a small club which is sometimes darker ; thorax scarcely broader 

 than long, much narrowed in front, very little rounded at the sides, 

 closely punctured; elytra much broader at base than the base of thorax, 

 separately rounded at apex and leaving the pygidium exposed, with 

 plainly but shallowly punctured striae ; breast densely pubescent ; 

 femora a little thickened in the middle, without teeth; the species closely 

 resembles a small Gymnetron. L. lf-2 mm. 



Male with the rostrum shorter and the antennae inserted before middle; 

 in the female the rostrum is longer and thinner with the antennae inserted 

 in the middle. 



On species of Salix ; usually found on the catkins in spring; rare; Burwell Fen. 

 Cambridge (Power) ; Little Brickliill, near Stony Stratford, on sallows, April, 1852 

 (S. Stevens); near Haileybury (H. Gorham). 



ELLESCHINA. 



This tribe contains the small genus Elleschm, which is closely allied 

 to Erirrhinus, but differs in having the tarsal claws armed with a strong 

 hooked tooth at base; the species are small with the antennas 11-jointed 

 and inserted before the middle of the rostrum which is moderately stout; 

 the eyes are subrotundate and only slightly prominent ; the thorax is 

 not constricted at apex; the elytra have the shoulders well marked and 

 completely cover the pygidium, and the legs are rather short and stout 

 with all the tibiae furnished with a strong spine at apex. 



EXiXiESCHUS, Stephens. 



This genus contains three or four species, which live ii< the larval 

 state in the catkins of willows, sallows and poplars; they are found 

 in Europe and Northern Asia, and one of them extends to the United 

 States a species has also been described, according to the Munich Cata- 

 loue, from New Holland ; two occur in Britain, but one of ^hese appears 

 to require further confirmation as indigenous. 

 1. Eostrum black ; elytra black with a denuded dark spot or 



fascia (sometimes rather indistinct) behind the middle 



of each, near suture E. BiruNCTATUS, Z>.
