to its liability of being distributed on nursery stock. It is a native 

 American species and evidently introduced into Europe on rhodo- 

 dendrons exported from America. It is reported from Holland and 

 England and may occur in adjacent countries where rhododendrons 

 are grown. The eggs have been found on rhododendrons received 

 in this country from Holland and England.

LIFE HISTORY OF A BOATMAN.

 regarding the life histories of some of them. 



However, the fact that our information concerning some of the 

 aquatic bugs has been meager, has not been due to a neglect on the 

 part of our best known workers in this group. For Dr. Kirkaldy, 

 Dr. Abbott, and Mr. de la Torre Bueno have endeavored to provide 

 the much needed information. 



The late Dr. Kirkaldy, though a taxonomist primarily, experi-

Among the most difficult of the aquatic insects to rear have been
