REPRODUCTION OF INSECTS. 



DURING the period of transformation from egg 

 to imago the internal organs as well as the 

 external paits of the insect un- 

 dergo profound changes. 



Whoever has looked at a 

 caterpillar, and then at the 

 chrysalis or pupa, hair-less, leg- 

 less, quiescent, and then at the 

 winged imago, can easily believe 

 that the tissues have undergone 

 great alteration ; but while some 

 structures disappear entirely and 

 others come into existence, the rcpr 

 tivc glands are present from the 

 ning. They can be traced from one 

 of the line of development to the other; 

 in the larva they may be seen, and through the 

 pupa they persist to mature in the imago. 



This egg material, like the amoeba, seems to 

 have great power to live. 



The whole life of the insect appears to be one 

 vast, complex, stupendous preparation, whose end 

 is love.
