quently have the head broader, the mandibles stronger and more sa- 
lient, and the anterior legs longer. 
Crytura, Leach, Fab.— Me oiontua, Geoff. 
C. quadripunctata ; Chrysomela quadripunctata, L., Oliv., 
Co]. VI, 96,1, 1. From four to five lines in length; black ; ely- 
tra red, each marked with two black dots, the anterior of which 
is the largest. 
The larva inhabits a coriaceous tube that it drags about with 
it, and which with the animal was sent to me by M. Waudoner, 
from Nantes *. 
There, the elytra, strongly dilated exteriorly at their origin, and 
then suddenly narrowed, present a deep emargination. The pos- 
terior angles of the thorax are acute, arched and form a roof; the an- 
terior are strongly curved underneath. The antenne are laid along 
its inferior sides, or are lodged under its edges. ‘The eyes are evi- 
dently emarginated in several. The superior surface of the body in 
those, and they are the greatest number, where it is less short and 
convex, is usually very uneven. 
These Chrysomeline are exclusively proper to the western conti- 
nent. 
Curamys, A noch. 
Where the form of the body approaches that of a short cylinder or 
of a cube, with the thorax abruptly elevated, and as if hump-backed 
in the middle, and the middle of its posterior margin prolonged or 
unilobate. The body is in general extremely scabrous. In some the 
labial palpi are forked f. 
Lamprosoma, Aird: 
Where the body is almost globular, extremely convex, very smooth, 
and the thorax very short, very broad, gradually raised and slightly 
lobate at the middle of its posterior margin. The five last and ser- 
rated joints of the antennz are less dilated than in the preceding 
ones f. 
Sometimes the antenne, evidently longer than the head and thorax 
united, are simple and filiform, or thickest at the end, or even termi- 
nated in a club, in which case they are serrated, but only from the 
seventh joint. The body, in several, is ovoid and narrowed before. 
The last joint of the antennze is appendiculated, so that their number 
seems to amount to twelve.
