Fernald ; to Bulletin No. 19 of the Hatch Experiment Sta- 

 tion, in which Professor Fernald gives a full description of 

 the moth ; and to ' ' The Massachusetts Ploughman " of Sat- 

 urday, April 9, 1892, volume LI., No. 28. 



We find that many parasites and flesh-eating insects prey 

 upon the gypsy moth, and that fowls and toads eat them ;

 gypsy moth : — ■
