. American bee journal. Bee culture; Bees. cylindrical reservoir at its base (fig. s) which is entirely shut off from the hol- low (fig. h) in the more slender part of the awl, which latter serves no purpose, except to give strength and lightness. The reservoir connects at its base with the poison sack, and below by a slit with the opening (rig. n) made by the approximation of the three awls. The other two awls (fig. b, &, b) which we will call lancets, are also hollow (rig. i: i). They are barbed (fig. tt, a, u) much like a fish-hook, except that there are eight or ten barbs instead of one. Five of the barbs are large and Sting with Lancets dravm one side, cross-section of Sting and a Lancet, much magnified. c— Poison sack. 0,0—Openings from hollow m^Tube from sack to res- in lancet, ervoir. u, u—Barbs, s—Reservoir. h— Hollow in awl. a—Awl. i, i—Hollows in lancets. b, b—Lancets. t, t—Ridges in awl. e, e—Valves. V—Groove in lancet. These barbs catch hold and cause the extraction of the sting when the organ is used. Near the base of each lancet is a beautiful valvular organ (fig. e, e). The hollow inside the lancets (fig. i, i), unlike that of the awl, is useful. It opens anteriorly in front of the first six barbs (fig. o, o), as shown by Mr. Hyatt, and posteriorly just back of the valves into the central tube (fig. rt), and through it into the reservoir (fig. s). The poison then can pass either through the hollow lancets (fig. i, i) or through the central tube (fig. 71), between the three spears. The lancets are held to the central 543 piece by projections (fig. t, t) from the latter, which fit into corresponding grooves (fig. V) of the lancets. In the figure the lancets are moved one side to show the barbs and the valves. Nor- mally they are held close together, and thus form the tube (fig. n). The parts of the sting are moved by muscles connecting the bases of the parts and extending from the parts to the large chitinous supports
