294 RHYNOHOPHORA. {Acalyptus. 
ACALYPTUWS, Schonherr. 
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 ; 
antenne 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 strie; breast densely pubescent; 
femora a little thickened in the middle, without teeth; the species elosely 
resembles a small Gymnetron. L. 1{-2 mm. 
Male with the rostrum shorter and the antenne inserted before middle; 
in the female the rostrum is longer and thinner with the antennz inserted 
in the middle. 
On species of Salia ; usually found on the catkins in spring; rare; Burwell Fen, 
Cambridge (Power); Little Brickhill, near Stony Stratford, on sallows, April, 1852 
(S. Stevens); near Haileybury (H. Gorham). 
ELLESCHINA. 
This tribe contains the small genus E/lesehus, 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 antenne 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 constrieted 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 tibize furnished with a strong spine at apex. 
ELLESCHUS, Stephens. 
This genus contains three or four species, whieh live in 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- 
logue, from New Holland ; two occur in Britain, but one of ‘hese appears 
to require further confirmation as indigenous. 
J. Rostrum black ; elytra black with a denuded dark spot or 
fascia (sometimes rather indistinct) behind the middle 
of each, near suture E. piruncratvs, L.
