JL HE genus Chrysomela is extremely extensive, 

 and some modern entomologists have subdivided it 

 into several others. 



Many of the Chrysomelae are very nearly allied 

 in point of habit or general appearance to the 

 Coccinellae, and have accordingly by different 

 authors been arranged in either genus. Of this 

 kind is the beautiful insect called Chrysomela 

 Populi or the Poplar Chrysomela: it is about twice 

 the size of the common or seven-spotted Coccinella, 

 and is of a bright red colour, with the tips of the 

 wing-shells black, and the thorax of a greenish or 

 blueish black. It is found on the black and white 

 poplars, willows, &c. and proceeds from a larva of 

 nearly similar appearance to those of the genus 

 Coccinella : it is of a pale yellowish green colour 

 speckled with black, and edged with rows of small 

 tubercles, those on the sides projecting in such a 

 manner as to represent so many conical papilla?.
