'JUNE-BUG' (BEETLE). 



How does the size of the head compare with that of the 

 grasshopper? Can you find both ocelli and compound eyes? 

 Notice the antennse on the front of the head. Draw one. 

 \\Tiat changes would you need to make in the antenna of a 

 grasshopper to make it like that of the June-bug? Can you 

 find labrum, mandibles, maxilla, and labium as in the grass- 

 hopper? 



How many pairs of walking-legs do you find? Do you find 

 segments to correspond? What name must be given to the 

 large segment just back of the head? Examine a leg: Do 

 you find in it the same segments that occur in the leg of the 

 grasshopper? 



Lift one of the hard outer wings (elytra). Do you find 

 veins, like those of the grasshopper, in the elytron? Is there a 

 second pair of wings? Are they as long as the elytra? How 

 are they folded? 



Study the abdomen. Can you find the membranous portion 

 uniting dorsal and ventral halves of the somites? Are spiracles 

 present? Can you find any ' ears'? How many segments can 

 you count in the abdomen? Do you find anal cerci, or ovi- 

 positor Separate the flaps at the hinder end of the abdomen. 

 Can you find any additional segments? Draw a beetle from 

 above with elytra and wings extended.
