The Papilio. 



The Papilio, or Butterfly, belongs to the order Lepidop- 

 tera. There are a great many fpecies of this genus, generally 

 diftinguifhed by the colour of their wings : The more com- 

 mon forts, with their caterpillars, are fo well known as to 

 render a description of them unneccflary. The caterpillars 

 and chryfalids muft be carefully picked ofF, and the trees well 

 watered with clear lime-water and tobacco-water mixed* 



The Cicada* 



The Cicada, Frog- hopper, or Flea-Locuft, is a genus of 

 infects belonging to the order Hemiptera. The larvae 

 t)f feveral of this genus evacuate great quantities of a frothy 

 matter upon the branches and leaves of plants or trees, in the 

 midft of which they conftantly refide, probably for fhelter 

 a gain ft other animals ; perhaps, alfo, the moifture of this foam 

 may ferve to feeure them from the fultry rays of the fun. 



As the froth emitted by thefe infects is very unfightly, and 

 as they are alfo hurtful to trees, by eating the leaves^ they 

 lhould be deftroyed by rubbing off the larvae with the hand, 

 and afterwards watering the tree plentifully with foft water*
