Family CHRYSOMELIDyE. 
These are the “leaf-beetles,” having the same tarsal structure as in 
the “Cerambycidse”; but with antennae rarely as long as the body, the 
joints comparatively stouter and larger toward the tip. The species are 
rarely cylindrical and the thorax has usually either a lateral margin or 
a distinct suture. 
The larvae are “slugs” or “grubs,” often stout and chunky like those 
of the potato beetle and feeding on leaves, or they may be long and slen¬ 
der, mining in root or leaf tissue. They vary much in habit, although 
always feeders on vegetable tissue, and many of them rank among the 
first-class pests. As against those that feed openly, the arsenites are 
usually available; but there are some that must be dealt with in other 
ways, depending on their habits.
