live of New Holland, of a beautiful green colour, 

 with the transparent wings ornamented by green 

 veins. 



Among the smaller European Cicadae one of the 

 most remarkable is the Cicada spumaria or Cuc-

 which is sometimes so overcharged with moisture, 

 that a drop may be seen hanging from its under 

 surface. The included larva, or pupa, (for no ma-

 sap of the plant, may be observed by examining 

 the under part of the thorax, where it will be seen 

 pressed down in a strait direction from the head. 

 When the time arrives in which the animal is to 

 undergo its change into the complete insect, it
