Leave the maxillae attached to the head till later. 4. Remove the head of the locust and pin it with the hinder side uppermost to a piece of cork or block of wood. 5. With the head in this position the flaplike lower lip or labium (la'bi-uni) can be easily seen. Like the maxillas, the labium consists of several parts. 6.

With the head in this position the flaplike lower lip or labium (la'bi-uni) can be easily seen. Like the maxillas, the labium consists of several parts. 6. Lift the free end of the labium with a pin and observe the tonguelike organ which arises from the inner side of it, and pro- jects between the maxillae; this is the hypopharynx (liy- po-phar'ynx). 7. Remove the labium and the hypopharynx and save them. 8. After the removal of the labium it will be easier to remove the maxillae than before. Remove them and save them. 9. Arrange the mouth- parts on a card as shown in Fig. 5 and gum them in place. 10. The five-jointed appendages of the maxillae are the maxillary palpi. The singular of palpi is palpus. 11. The three-jointed appendages of the lower lip or labium are the labial palpi. Review.—The mouth-parts of a locust consist of an upper lip, the labrunt; an under lip, the labium;.
