CHRYSOMEI,A. 
379 
Genus XI ,—Chryfomela. 
From the variety of different colours with which the 
infefls of this tribe are adorned, they have been called 
chryfomel t. There are no lefs than an hundred and 
twenty-two different fpeeies defcribed by naturalifts, di- 
ftinguifhable by their fixe, colour, and manners.. Ihey 
all agree, however, in having the antennae momhform, 
and increafing in thicknefs towards the ends : Neither the 
thorax nor elytra are margined *. 
The chryfomelae are to be found almoft every where ; 
fome frequent the open fields ; ethers the woods, and 
many the gardens. Their larva prey upon the leaves of 
trees, rejefting the fibrous parts ; fome of them deftroy 
the -rafs while in that ftate i and there is in Sweden a 
particular fpeeies, faid to be guilty of very extenfive de- 
predations on the pafture grounds. This infeft, when it 
has reached its winged ftate, is of a fine gloffy green, 
mixed with a {hade of blue ; the whole diffeminated with 
a number of fmall fpots, which form irregular ftrise f. 
Chryfomela fanguinolenta, has the elytra of a deep 
black, interfperfed with fmall fpots, which gives them 
the appearance of fhagreen : Their margins, and the 
wings which they cover, are marked all along with a 
broad band of light red, which refembles ftreams of 
blood: the belly, thorax, and head, are of a blue colour.
