ScAEABAEiDAE. The Lamellicorn Beetles 



This family which is probably the most aristocratic be- 

 cause its name is taken from the Latin Scarabaeus meaning 

 *a beetle,' may be roughly divided into two groups according 

 to habits. However, as each genus generally has an adult 

 food habit of its own, one cannot generalize and they will be 

 treated separately.
