COLEOPTERA. 83 
small, hardly perceptible to the naked eye, and conical; the anterior 
prolongation of their head resembles a rostrum or proboscis. 
Sometimes the antennze are at once straight, inserted on the ros- 
trum, and consist of nine or ten joints. 
Those, in which the three or four last joints are united into a club, 
form the genus ; 
ArrteLases, Lin.,and more particularly of Fab.—BrEcmarss, 
Geoff. 
They attack the leaves or most tender parts of plants. Most of the 
females roll up these leaves into a tube or cornet, in which they de- 
posit their eggs, thus preparing a domicil for their young ones, which 
also furnishes them with food. 
The proportions of the rostrum, the manner in which it termi- 
nates, as well as the tibiz and form of the abdomen, have given rise 
to the four following subgenera: Aproprerus, ArrEeLABUs, Ruyn- 
cHires, and Arion. The first is the most distinct. The head of 
these Insects is narrowed posteriorly, or presents a sort of neck, and 
is united to the thorax by a kind of rotula. Their snout is short, 
thick, and widened at the end, a character common to Attelabus, 
properly so called, but where the head, as in the two other subge- 
nera, is received into the thorax up to the eyes. Here the snout is 
elongated into the furm of a proboscis. In Rhynchites, it is some- 
what widened at the end, and the abdomen is almost square.

and pubescent; antenne and extremity of the proboscis black. 
The larva of this species lives in the rolled leaves of the 
Vine, from which, in certain seasons, and when unusually nu- 
merous, they sometimes completely strip the foliage. They 
are known in some parts of France, by the names of Lisette, 
Béche, &c. 
The snout in Apion is not widened at the end, and even frequently 
terminates ina point. The abdomen is strongly inflated.* 
The following genera have been formed with Rhynchophora, very 
similar to the Attelabi, but with a narrower and more elongated 
body. 
Ruworti, Airb.—Beruus, Schenh., 
Where the antenne gradually enlarge without forming a club, and 
the body is almost linear f. 
Evrummus, A7rb., 
Where they terminate in an elongated club, of which the last joint 
is very long in the males}.
