attain the length of about 16 to 18 mm. They live from three to 

 four years in the larval stage, and when full-grown are about 1 inch 

 to H inch in length, and about ] inch to inch in breadth. They

 third or last pair as the longest, whereas they are considerably the short-

 to a perfect insect in summer (fig. 46).
