WASPS, SOCIAL AND SOLITARY

 fresh, but all quite dead. We have no doubt that punc- 

 tatus completely provisions one pocket and closes the

 other, making a series of six or eight independent cells. 

 The provision for one larva is probably twelve or four- 

 teen bees, the capture of which, in good weather, would 

 be a fair day's work. 



That the males do not always stay on in their ancestral 

 home is shown by an observation that we made on the

 Nothing was stirring at half past three o'clock in the 

 afternoon, and we had given up work and started for 

 home, when, in going up an inclined part of the field,
