 authorities on the continent and America. 



It is true much yet remains to be done ; thus, even the 

 ripe eggs and larval stages of such ubiquitous forms as the

 a store of knowledge is being gradually accumulated — know- 

 ledge not only of value now, but that will be permanently 

 advantageous to the department.
