The pupils will notice the well marked division of the 
body into head, thorax, and abdomen. 
General Description. The head bears the antennae 
—two mandibles—two compound and three simple eyes, 
and the mouth.- To the thorax, or chest, are attached on 
the under surface, three pairs of legs, and above these two 
pairs of wings. Hach pair of wings is firmly hooked 
together—the hooks occur on the upper margin of the lower 
pair, and fit into folds on the lower margin of the front and 
upper pair. The abdomen consists of a number of rings or 
segments. Hach entire segment is made up of two portions, 
an upper and a lower half, connected by an elastic mem- 
brane. Both the chest and abdomen are covered with 
hairs. At the lower end of the body is a sharp stabbing 
instrument known as the sting.
