T HIS little creature, though but feldom taken no¬ 
tice of, affords an agreeable variety of fubjedfe, 
when examined by the microfcope. It is produced from a 
worm hatched in an egg, depoiited by its parent under 
the grafs in meadows. 
Thefe worms are to be met with but in the hot weather 
upon the ground under the grafs in the meadows and 
fields. Fig. i£>3. reprefents one of them, which could

The tails both of the male and female are of a curious 
ffruffure, that of the female is fharp, and of the con- 
fiftence of bone, wherewith fhe perforates the ground,
