Mr. Riederer, in explaining his exhibits, said : — " Like the 

 ovipositors of all the Ichneumonidce these consist of the oviposi- 

 tor proper and two sheaths. The ovipositor proper serves for 

 the boring of bark or wood, or the stinging of larvae and pupae, 

 according to the nature of the species, and also for the con- 

 ducting of the eggs to the place, where they are to be deposited.
