In the preceding kind, the eggs are laid in the back part of the 

 cavern where the creature lives ; evenly arrang'd ; and when the 

 time of their hatching is near, the Fly brings in a number of 

 flaughter'd Infects, for the food of the expected young ones : me 

 then clofes up the mouth of the hole with mud, and her care is over. 

 When the young worms hatch, they find their food ready ; and when 

 they have eaten their fill, they reft, and take their change into the Fly. 



But this creature lays her eggs in the body of a living Caterpillar : 

 they hatch, and eat that creature up, even while itielf is feeding : 

 at their appointed time they hatch : and 'twas long a wonder among 

 the curious, how a Caterpillar produced this Fly, inflead of a 

 Butterfly, or Moth ; or how one Infect changed to many. 



The Head of this creature is of a chefnut brown, with a fhade of 



blue. 

 The Eyes are black, and large. 

 The Antlers are of a ruddy brown. 

 The Feelers are blackifh. 

 The Jaws are hard, ferrated, and yellow., 



The Trunk is of a ruddy brown. 



The Scutcheon is yellow. 



The Thread which fattens the two parts together, is alfo vellovr. 



The Body is of the colour of rufty iron ; but there is a fkin of yel- 

 low covering part of it from the end of the thread. 

 The Air-holes are black. 



The Legs are partly brown, and partly yellow. 



The Wings are of a dufky brown,, 



The Sting is yellow. 



The drawing of this, as of the former, is not greatly magnify 'd ; 

 the fame fourth glafs was us'd to it ; the creature being naturally of a 

 fize nearly big enough to mew its own particularities ; and always 

 here the lefs magnifying is wanted^ the lefs is us'd.
