ries» These leaves must be carefully picked olF, and the in- 

 sects crushed : The trees must then be washed with clear 

 lime-water mixed with tobacco-water. This washing would be 

 found useful when the insect is in its larva state, after picking 

 oiF and crushing as many of the caterpillars as possible. Set^

Sphinx or Haxvk 3ioth, 



There are 165 species of thi& genus, ten of which are 

 found in Great Britain and Ireland. 



The name of Sphinx is given to this genus on account of 

 the singular attitudes of their caterpillars, who apply the hin- 

 der part of their body to a branch of a tree, and hold the rest 

 of it erect, like the Fabulous Sphinx, Most of them spin their 

 cod under ground. The sphinges appear either early in the 

 morning, or after sunset, and fly heavily and sluggishly, often 

 emitting a kind of sound. M-atiy of the caterpillars are green 

 and smooth, some brown, or yellow, and others are spotted, 

 or have belts. The sphinx may be destroyed by the same me- 

 thod as the phaleena. 



The Fhalcena Bombyx Neustria. 



The Phalaena Neustria, or Lackey Moth, lays its eggs in 

 rings round the branches of fruit-trees, exhibiting the appear- 

 ance of a necklace. These being very hard, and adhering close 

 to the bark, must be cut off with a sharp knife, taking care 

 to wound the bark as little as possible ; and wherever the knife 

 enters, it will be necessary to rub in a little of the composi- 

 tion. 



The Papilio. 



The Papilio, orButterfly, belongs to the order Lepidoptera. 

 There are a great many species of this genus, generally distin- 

 guislit d by the colour of their w^ings^: The more common sorts, 

 with their caterpillars, are so well known, as to render a de- 

 scription of them unnecessary. The caterpillars and chrysalids 

 must be carefully picked, and the trees well watered with clear 

 lime-water and tobacco-water mixed. 



The Cicada* 



The Cicada, Frog-Hopper, or Flea-Locust, is a genus of 

 insects belonging to the order Hemiptera. The larv« of se- 

 veral of this genus evacuate great quantities of a frothy matter 

 upcjn the branches and leaves of plants or trees, in the midst of 

 Yrhich they constantly reside, probably for shelter against other
