An examinination of the whole body will readily show three divisions — the head, thorax, and abdomen. The head, apparently one piece, contains the mouth, eyes, and the long horns, known as an- tennae; the thorax is the heavy central part of the body, furnishing attachments for the wings and legs; the abdomen is the slender portion extending backward from the base of hind wings. The head.— The accompanying figures show the head with mouth closed (fig. 12), but upper lip, labrum, removed to reveal comparative size of jaws and head. Fig. 13, with mouth open, illustrates the tongue, hypupharynx in the center, mandibles, and part of the maxillae on Fig. 12. (Original.) Front view of head, with clypeus and labrum removed to show mandibles in position, a, antenna; b, ocelli; B, compound eye; f, mandible; d, maxilla; e, maxillary palpus; /'.labium; g, labial palpus.
