The ribs or veins consist of a tube within a tube, the inner one forming an air-tube, the outer one carrying blood.

On the costal edge of the secondary wings we often find hooks (Fig. 2, h) to attach them to the front wings. The wings are moved by powerful muscles, compactly located in the thorax (Fig. 2S), the strength of which is very great. The rapidity of the vibrations of the wings when flight is rapid, is almost beyond computation. Marey found by his Fig. Hairs of Bees.âOriginal. ingenious and graphic method that they number in the bee 190 in a second. This may be far from the maximum. Think of a tiny fly out-stripping the fleetest horse in the chase, and then marvel at this wondrous mechanism. The legs (Fig. 1, g, g, £â ) are six in number in all mature insects, two on the lower side of each ring of the thorax. These are long or short, weak or strong, according to the habit of the insect. Each leg consists of the following joints or parts : The coxa (Fig. 67, cy, which moves like a ball-and- socket joint in the close-fitting coxal cavities of the body- rings. Next to this follow in order the broad trochanter (Fig. 67, T,) which is double in several families of Hymenoptera like the very valuable ichneumon and chalcid flies, the large, broad femur (Fig. 66, F), the long, slim tibia (Fig. 67, T), frequently bearing strong spines at or near its end, called tibial spurs, and followed by the from one to five jointed tarsi (Fig. 67, 1, 2, 3, 4, 5). All these parts move freely upon each other, and will vary in form to agree with their use. At the end of the.
