The Life Processes of the Individual 135 is concave on the posterior surface to fit the rounded thorax. The three ocelli (0) in the worker are arranged in a triangle at the top of the head, the antennae (Ant) arise from the center of the face. On the posterior surface is the foramen magnum (For) through which pass nerves, oesophagus, dorsal blood vessel and tra- cheal tubes connecting the head and thorax. Below the foramen magnum is the fossa (PrbFs) where the proboscis is attached. The heads of the queen and the drone differ from that of the worker in size and shape (Fig. &9, A, B and C). The face of the queen (B) is more nearly round and is relatively wider. That of the drone (C) is larger and nearly circular, this being due to the unusual develop- ment of the compound eyes (E) which meet at the vertex of the head, crowd- ing the ocelli (0) to the front near the bases of the antenna. The head of the queen is smaller than that of the worker. The mandibles (Fig. 68, A, Md) or jaws, which are of special interest to the beekeeper, are situated on the sides of the mouth anterior to the base of the •proboscis, being attached to the cls^eus (Clp) and the postgena (Pge) by two articulations, so constructed that they serve only to crush or bite food and not to grind it. The mandibles of in- sects, when present, work sidewise and not up and down in a median plane, as do our jaws. The mandibles of the three types of bees differ in shape and size. Those of the worker (Fig. 70, A) are hollowed out and have smooth and rounded edges, while those of the drone (Fig. 70, B) and of the queen (Fig. 69, B) are pointed and Fig. 69. — Anterior view of heads of worker (A), queen (B) and drone (C). with front, anten- nae and proboscis removed from Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabili
