The lancets slide on a grooved track the full length of the sheath, past the bulb and diverge along the two basal arms. The sheath and lancets combine to form a hollow tube (PsnC) through which the poison flows. The arms of the sheath are attached at their anterior ends to oblong plates (Ob) which overlap the sides of the sting. To these plates are attached palpi (StnPlp), soft white pro- jections provided with sense organs, by means of which the bee can tell when she is in con- tact with the object which is to be stung. The lancets are attached to triangular plates (Tri) which in timi articulate with the quadrate plates (Qd). By the move- ments of these plates on each other the lancets are slid along the sheath when the sting is used. It has been shown by Zander * that the triangular plate {Tri) is part of the eighth sternum, the quadrate plate (Qd) is part of the ninth tergum and the oblong plate (Qb) is the ninth sternum. "In the accessory plates of the bee's sting we have a most excellent illustration of how parts of a segment may become modified to meet the requirements of a special function, and also an example of how nature is ever reluctant • Zander, Enoch, 1899.
