 With that lancet, whicli we have already defcribcd, flic 

 excavates a number of holes in the dried branch of a 

 tree ; into each of thefe holes eight or ten of her eggs 

 are dropped ; there they are fiirFounded with tliat kind 

 of food which is mod fuitohle for them in their larvps 

 ihite. The difpofition of the eggs is in rows, and placed 

 in the middle of the trees ; the foft fiihfLance of which

 The infeft that proceeds from each of thefe eggs, after it 

 has grown for fome time, and before reaching a f:xe in-

 hole, takes a fined departure from the place of irs birth. 



The larvqs having thus left their egg ftate, and acquir-

 formed for digging the ground, foon apply them to that 

 purpofe, and excavate for themfelves a fubterraneous re- 

 treat among the roots of plants, which they gnaw, and 

 fupport thenafelvcs upon the juices that exfude from 

 them *. In this Rate they remain till they are ready to 

 undergo another transformation, which introduces them 

 into the open air in the form pf winged infecls. 



A fliort time after, the gralliopper appears in its lad

 are of opinion that the notes of the gradiopper are pro- 

 duced by rubbing the two hind legs of the animal againd 

 each other. M. de Recwmr and Limiatis, who have mi- 

 nutely examined thefe infecls, derive tlicir vocal powers
