114 SOCIAL LIFE IN THE INSECT WORLD 



insensate massacre continues I shall soon find my cage 

 depopulated. 



Are my beetles hoary with age ? Do they die a natural 

 death, and do the survivors then clean out the bodies ? 

 Or is the population being reduced at the expense of 

 sound and healthy insects ? It is not easy to elucidate 

 the matter, since the atrocities are commonly perpetrated

 protest except his futile efforts to escape, the victim is 

 forced to submit. The skin finally yields ; the wound
