lines ; oval, oblong, and blue; elytra fulvous or red, and the inner 
angle of their extremity marked with a black dot. On the Wil- 
low and Poplar ; its larvee lives on the same trees, and frequently 
in society. 
This species, ‘and some others equally oblong, with a thorax 
narrower than the elytra, and forming a transversal square 
thickened on the sides, constitute the genus Lima of Megerle *. 
We will terminate this tribe with those Chrysomelinze whose max- 
illary palpi are attenuated at the extremity and terminated in a point, 
They will form two subgenera. 
Puapon,—Corarnuus, Meq., 
Where the body is ovoid or orbicular |, and 
Prasocurts, Lat—Hetopes, Fab., 
Where the body is narrower, more elongated, and almost a parallelo- 
piped, and where the diameters of the thorax are nearly equal. The 
four or five last joints of the antenne are dilated, and almost form a 
club ¢

In the third and last tribe of the Cyclica, that of the GALERuciTa, 
we find antennz always at least as long as the half of the body, 
of equal thickness throughout, or insensibly thicker towards their 
extremity, inserted between the eyes, at but little distance from the 
mouth, and usually approximated at base, and near a small longitu- 
dinal carina. The maxillary palpi, thickest about the middle, termi- 
nate in two joints, in the form of a cone, but opposed or united at 
base, the last short, and either truncated, or obtuse or pointed. The 
body is sometimes ovoid or oval, and sometimes almost hemispherical. 
In several, and particularly the smaller species, the posterior thighs 
are very stout, which enables them to leap. 
This tribe is composed of the genus 
GALERUCA, 
Which we will divide into two principal sections; those which are 
destitute of the power of leaping, or the Isopoda, and the Jumpers or 
the Anisopoda. 
Some species foreign to Europe, in which the penultimate joint of 
the maxillary palpi is dilated, and the last much shorter and trun- 
cated, form the genus

lowing: raphani, vitelline, polygoni, &c. The antenne of the species called armo- 
racie, cochlearie, in the thickening of their terminal extremity, closely approach 
those of the Helodes.
