THE HONEY BEE 67 



Draw both wings (X4)- 



(3) Lay the wings in their natural order on a glass 

 slide. Examine the internal margin of the outer, or front 

 wing, and the costal margin of the inner, or hind wing. 

 Do you find there a method of attachment of the wings to 

 one another? Can you tell now how the wings are used? 

 These hooks are called hamuli. Make a drawing of these 

 margins showing how they are specialized. 



(4) Examine the attachment of the legs to the body. 

 Are all the segments present? Are all the legs alike. 

 What specializations do you notice in the second and third 

 pairs ? One joint of the tarsus and one of the tibia are en- 

 larged. This flattened portion is called the pollen basket. 

 The pollen basket is formed by an enlargement and curving 

 of two of the segments of the leg. Which segments are they ? 

 Have you ever seen a bee carrying pollen? How is the 

 pollen fastened to the leg? Does each leg have a pollen 

 basket ? 



Draw one of the third pair of legs (Xs)- 



The Abdomen. — (i) How many segments in the ab- 

 domen of the bee? Is the number the same on the dorsal 

 and ventral sides? 



(2) Find the sting by laying the bee on the dorsal side 

 and pressing on the abdomen about four segments from 

 the posterior end. The sting will appear between the seg- 

 ments. Seize the tip firmly with the tweezers and pull it 

 out with a quick movement. Lay the sting and the parts 

 that come with it on a slide and with the needles arrange 

 the parts carefully. 



The large part back behind the sting contains the poison 

 glands and the sac for holding the secreted poison. Look
