Ue-bugs. These form balls 

 of manure in which they 

 lay their eggs, and which 

 they roll off to some safe 

 place and conceal in the 

 earth. Related species 

 make holes in the ground 

 under a pile of manure 

 and fill these holes with 

 manure in which they lay 

 their eggs. The tumble- 

 bugs are typical Scara- 

 bseids and one of them was 

 the sacred beetle or Scarab 

 of the ancient Egyptians. 

 Quite a complex system of 

 mythology was built up 

 about the habits of this 

 insect. The student will

 clopoedia and there get 

 additional information re-

 large size more abundant 

 than those known as June- 

 bugs or May-beetles. They
