Page 98 



The shafts bored in dead wood are divided into cells by partitions of agglutinated 



wood-fragments. These are provisioned with a mixture of honey and pollen and 



an egg laid in each. The cells show succeeding stages in development, beginning 



with the egg in the lower right-hand cell.
