214 THE LIFE AND LOVE OF THE INSECT 



flings herself upon the saucy jade, buffets her and drives 

 her away. The moment the punishment has been ad- 

 ministered, she returns on guard and resumes her 

 sentry-go. 



Next comes the turn of a Leaf-cutter (Megachile Albo- 

 cincta, Perez), who, unskilled in the art of burrowing, 

 utilizes, after the manner of her kind, the old galleries 

 dug by others. Those of HaHctus Zebrus suit her very

 And so with the others who, by mistake or ambition, seek 

 to enter the burrow. 



The same intolerance exists among grandmothers. 

 About the middle of July, when the animation of the
