Pollen, however, forms only one portion of the food of the larva, and it must be mixed with honey to form ' bee bread' of a proper composition. This honey is also gathered from flowers, and the mouth parts are modified to this especial end. We have two series of bees dis- tinguished by the character of the mouth parts,—the short-tongued and the long-tongued,—both of which may be either solitary or social. The short-tongued bees have the lower lip modified into a bladder-like structure, more or less pointed at the tip, and set with regular rows of short hair or flattened processes, an ideal tongue for gathering up the liquid nectar and bringing it into the mouth. Many of these bees are diggers, and build their nests in the ground, usually forming a single vertical burrow from which lateral branches diverge into
