Last of all, and most important of all to ordinary humanity, we come to the sting, with its append- age the poison-bag. It is well represented in No. 14. The main object of the sting, and its o'i- ginal function by descent, is that of laying eggs ; it is merely the ovipositor. But besides the grooved sheath or egg-layer (marked S in the illustration) and the two very sharp lances or darts (marked D) which pierce the fiesh of the enemy, it is provided with a gland which secretes that most unpleasant body, formic acid ; and when the wasp has cause.
