THE CRICKET : LABORATORY WORK. 



Do you find the same regions as in the grasshopper ? 

 Are there the same number of segments in the abdomen ? 

 and in the thorax ? Are the wings and the feet the same 

 in number in the two forms ? In the place of the cerci 

 what do you find ? Could you call these jointed appen- 

 dages ? How many parts do you find in the ovipositor of 

 the female ? What changes in the grasshopper ovipositor 

 would be necessary to make it like that of the cricket ? 

 Can you split any of the parts of the ovipositor of the 

 cricket ? Can you find the ear ? 



In the head are there the same eyes, antennae, and mouth- 

 parts ? Do the mandibles work in the same way ? Look 

 on the second long joint (tibia) of the foreleg for the ear.
