BUPRESTIS-BEETLES (Buprestidx). In these insects the 

 point at the hind part of the breast is immovable; the antennae 

 are finely serrate, and the colors are usually metallic. 



The larvae generally have the fore part of the body greatly 

 dilated and flattened (Fig. 54), and the body is nearly or 

 wholly destitute of legs; they live in the stems, roots, or trunks 

 of plants, shrubs or trees, and are sometimes very destructive.

One of their number, the Flat-headed Apple-tree Borer (Fig. 

 138), is very destructive to various kinds of fruit-trees. The 

 Cherry-tree Borer (Fig. 256) and the Raspberry Borer (Fig. 

 257), belong to this Family. 



SPRING-BEETLES (Elateridx). -In these insets the point at 

 the hind end of the breast is movable; the antenna3 are some- 

 times filiform, and the colors are usually brown or black.

They are at once distinguished from all other insects by the 

 power they possess of suddenly springing into the air when 

 placed upon their backs upon any hard, smooth surface.
