PLATE 1.29. QUEEN MIDDLE AND HIND LEG BASES

TOP RIGHT Ventral view of the middle and hind (rig t) leg bases. The coxae and trochanters of the bind (metathoracic) legs are on the right, those of the middle (mesothoracic) legs on the left. The rectangular plate between both sets of legs is the sternellum. The rhomboidal plate bounded by the four leg bases is the propodeal sternum; it is punctuated by a center apodeme. (x 47)

BOTTOM RIGHT Ventral view of the base of the metahtoracic leg. The major appendage here is the metathoracic coxa. The distal appendage that projects to the bottom of the field is the trochanter. ( x 55)

TOP LEFT. Sternal sclerite situated between the metathoracic coxae. This plate is more properly called the propodeal sternum. ( x 50)

MIDDLE LEFT Higher magnification of the propodeal sternum and the adjoining coxae of the mesothoracic legs. The hair plates (arrow) at the bases of the coxae are probably mechanoreceptors monitoring leg movement. (x 100)

BOTTOM LEFT Apodeme (cuticular invagination) and the surrounding propodeal sternum. ( x 300)
