Galerucidae. 



This family is exemplified by those very common striped beetles which infest and destroy 

 the cucumber plant. They are oblong, and are furnished with a small head and a narrow 

 thorax. Their antennae are about half as long as their bodies, of a uniform thickness, and 

 inserted near together and near the mouth. Their legs are of an equal size, though in some 

 the thighs are formed for leaping. They are small insects and vegetable feeders, and often 

 do considerable damage in gardens. 

 The family is divided by Westwood into two subfamilies : 1 . Galeeucides ; 2. Hal- 



TICIDES.

 obconic ; the third next in length, the two equaling the first or fourth ; the remainder 

 equaling the first or fourth : labrum entire : palpi indeterminate. Head small, exsert :
