Family BUPRESTIDiE. 
These are elongate, usually stout but sometimes cylindrical beetles, 
with broad thorax and elytra tapering back from the shoulders, the 
pro thorax closely united to the mesothorax. A large proportion of them 
are bronzed or metallic in color or reflection, and others are gaudily 
marked with red or yellow bands or spots. Many of them have the upper 
surface deeply grooved or pitted, and altogether they are very character¬ 
istic in appearance. Most of them are very active and fly readily, so 
that they are not often recognized except by collectors.
