The empodium (fig. 30 A, B, and C, Emp) consists of a terminal lobe bent upward between the claws (C) and deeply cleft on its dorsal surface (A), and of a thick basal stalk whose walls contain a number of chitinous plates. One of these plates is dorsal (A and C, hh) and bears five very long, thick, curved hairs projecting posteriorly over the terminal

THE ABDOMEN, WAX GLANDS, AND STING. 69 worker, but the drone's claws (C) are large and very strikingly different in shape from those of either the worker or the queen. The empodium (fig. 30 A, B, and C, Emp) consists of a terminal lobe bent upward between the claws (C) and deeply cleft on its dorsal surface (A), and of a thick basal stalk whose walls contain a number of chitinous plates. One of these plates is dorsal (A and C, hh) and bears five very long, thick, curved hairs projecting posteriorly over the terminal lobe, while a ventral plate (B and C, ii) is provided with numerous short thick spines. A third plate (A, B, and C, gg) almost encircles the front of the terminal lobe, its upper ends reaching to the lips of the cleft. When the bee walks on any ordinary sur- face it uses only its claws for maintaining a foothold, but when it finds itself on a smooth, slippery surface like glass the claws are of no avail and the empodia are provided for such emergencies as this. The terminal lobe is pressed down against the smooth surface and its lateral halves are flattened out and adhere by a sticky liquid excreted upon them by glands said to be situated in front of them, the muscle that flattens the empodial lobes the latter spring back into their original position by the elasticity of the chitinons band {gg) in their C Fig. .°>1.—A, outer view of hind claw of worker; B. same of queen; C, same of drone. On the relaxation of V. THE ABDOMEN, WAX GLANDS, AND STING. The abdomen of the worker and queen appears to consist of six seg- ments (figs. 1, 32, 33, II-VII). but it must be remembered that, as has already been explained, the thoracic division of the body in the Hymenoptera includes one segment, the propodeum or median seg- ment, which really belongs to the abdomen and is its true first seg- ment according to the arrangement in all other insects. Hence, counting the propodeum (
