 many species ; some larger, some smaller, than

 Although discovered alive with difficulty, it is 

 found abundant in the stomachs of the fish.

 or ovipositor, used for the purpose of piercing the 

 skin of caterpillars, in which it deposits its eggs,

 Ichneumon flies are the great check to the mul- 

 tiplication of the insect tribes.
