150 POPULAR ENTOMOLOGY. 



Ehynchites populi. (Plate II.) In this well-known 

 species the body is shining, of a golden green, or with a 

 bluish tint on the upper side, and dark violet beneath ; the 

 antennae are black ; the elytra punctured ; in one of the 

 sexes there is an acute spine on each side of the thorax, 

 projecting forwards. The length of this insect is three 

 lines ; it is found on poplar and birch trees. 



Ehynchites pubescens is somewhat longer in proportion 

 than the preceding, of a deep violet-colour, and clothed 

 with rather long hairs ; the elytra are marked with punc- 

 tured lines. 



Ehynchites Bacchus. A beautiful species, found chiefly 

 in Kent on the vine, and doing great injury by devouring 

 the tender shoots, extracting the sap with its long tubular 

 proboscis ; this causes the leaves to roll up, and in these 

 little tents, surrounded by a silken covering, the eggs are 

 deposited. 



The species of the family Ctirctdionidce have the EngHsh 

 name of Weevil, and may always be known by the elonga- 

 tion of the head into a snout Or rostrum.
