70 LLOVDS NATURAL HISTORY. 



These moths come freely to flowers at dusk, flying over 

 them somewhat in the manner of Sphinges, which some of 

 them considerably resemble in shape. They are generally 

 called " Sharks " by collectors. 



At one time Ur. Butler proposed to transfer this family to 

 the Notodontidcc^ but has now decided to replace them in the 

 N'odiuz.
