THE BUPODA, OR PHYTOPHAGA.

tora, of which the narrow and uniformly blue or brassy 
species are exceedingly common on willows, both in 
the summer on the leaves and trunk, and in winter 
hybernating beneath the bark in society. The larvae, 
also, are gregarious, feeding in rows upon the leaves, 
of which they devour only one side. 
The Galerucina are mostly oval and somewhat con- 
vex, being generally decidedly widest behind; their 
legs are nearly uniform, the hind femora being 
simple, and the front coxae approximated ; their 
antennae are of considerable length, closer together at 
the base than in the Chrysomelina, .and not thickened 
at the apex ; their head is inserted in the thorax 
almost up to the eyes, which are entire, the thorax 
itself being margined at the sides, more or less 
hollowed out in front, aud with produced front angles ; 
the maxillary palpi are thickest in the middle, with 
the apical joints resembling two cones, united at the 
base ; and the claws have a tooth in the middle. 
They are of softer integuments than the Chrysome- 
lina, and not so gaily coloured or metallic, though 
equally diurnal and attached to plants. 
Our largest species is Adimonia tanaceti, a dull 
black, sluggish, thickly and coarsely punctured 
insect, found ou the wild tansy, especially in chalky 
places on the south coast. It exhibits in a marked 
degree the peculiarity of the family of being widest 
behind ; and its female has somewhat the distended 
appearance of Gastrophysa above mentioned, possess- 
ing, also, though in a minor degree, Lina’s evil habit 
of distilling aud smelling. Of the others in this genus, 
A. caprese is exceedingly common on osiers, and less so 
on heath, — a very wide range of food-plant, — and.
