A family of moderate extent, comprising beetles which vary 

 much in shape and size. The larger ones are usually oblong ellip-

 either elongate and subcylindrical or short and ovate. Their bodies 

 are hard and inflexible, with usually a hi- >n/,ed or metallic surface.

 rate. Many of them resemble the click beetles in general form, but 

 have the thorax and abdomen firmly united, so that they have no 

 power of leaping. 



The Buprestida- are preeminently a tropical family, and in the 

 torrid regions reach a large size and reflect the light from their 

 polished bodies with an almost dazzling brilliancy. The adults of
