162 BEES OF GREAT BRITAIN. 



cornis: large numbers of them have been obtained from the 

 cocoons of that bee. 



I have observed Stelis ph&optera entering the burrows of 

 0. hirta and 0. ccerulescens ; it is parasitic upon these species. 



Stelis octomaculata is parasitic on 0. leucomelana, and Stelis 

 minuta is parasitic on the same species. 



T trust it will not be considered that I have enlarged more 

 than is desirable upon the economy of these interesting insects ; 

 but who can reflect upon the variety of situations in which they 

 form their cells, the expedients to which they resort, and not 

 admire the patience, the skill, and the admirable ingenuity by 

 which these bees accomplish their purpose ?
