fpon as they are difelofed, merit our particular notice. 
With that lancet, which we have already deferibed, 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 furrounded with that kind 
of food which is mod fuitable for them in their larva; 
fiate. The difpofitton of the eggs is in rows, and placed 
in the middle of the trees ; the foft fub dance of which 
is the firft food of the infect after it leaves the ovum. 
The infeft that proceeds from each of thefe eggs, after it 
has grown for fome time, and before reaching a fize in- 
compatible with efcaping by the narrow mouth of the 
hole, takes a final departure from the place of its birth. 
■The larva: haying thus left their egg ftate, and acquir- 
ed the ufe of their limbs, the two anterior of which are 
formed for digging the ground, loon apply them to that 
purpofe, and excavate for themfelves a fubterrar.eous re-

fnpport themfelves upon the juices that exfude from 
them *. In this date they remain till they are ready to 
■undergo another transformation, which introduces them 
into the open air in the form of winged infe&s. 
A ihort time after, the gralhopper appears in its lad 
flage of perfeelier. ; it fpreads over the meadows, which 
it fills with its chirruping drains, which are the calls of 
the male inviting the female to love. Some naturalids 
arc of opinion that the notes of the grslhopper are pro- 
duced by rubbing tbe two bind legs ol the animal asainft 
each other. M. <lc Reamur and Linr.ccu x, who have mi-

from a very different fource. On examining the male,
