ANATOMY OF THE BEE. 605 A close examination of the sting proper shows that both the bnlb and the tapering shaft are formed of three pieces. One is dorsal {SliB and ShS) while the other two (Let) are ventral (of course only one of the latter shows in side view). Furthermore, the basal arm on each side is formed of two pieces, one of which [ShA) is continuous with the dorsal piece of the sting, while the other (Lei) is continuous with the ventral rod of the same side. Since these ventral rods are partially enclosed within a hollow on the under side of the dorsal piece, the lat- ter is called the slieath of the stlrtg. It con- sists (f the terminal shaft of the sheath iShS), the biilh iShB), and of a basal arm [ShA) on each side. The ventral pieces [Let] Vx P tubular, alkaline gland (BGl). By move- ments of the triangular jilates (Fig. 5, Tri) the lancets slide back and forth against tlie sheath while the poison exudes in tiny drops from an opening between them near the tips. The poison-sac has no muscles in its walls, and, hence, can not force the poison through the sting. The poison, in fact, is driven out of the latter by a force-pump inside of the bulb. This consists of two pouch-like lobes situated on the upper edges of the lancets, having their cavities open posteriorly. When the lancets move forward the walls of these pouches collapse; Ijut when the motion is reversed they tlare apnrt and drive the poison contained in the bulb back through the shaft and out at the end.
