" These are the only notices I have thus far been able to 

 find of the introduction of this insect into America. Mr. 

 Samuel Henshaw and Dr. Hagen of Cambridge have both 

 informed me that the entomologist who introduced this 

 insect was ISIr. L. Trouveh)t, now living in Paris, but at that 

 time living near Gienwood, Medford, where he attempted 

 some experiments in raising silk from our native silk worms, 

 and also introduced European species for the same purpose. 

 Dr. Hagen told me that he distinctly remembered hearing 

 jNlr. Trouvelot tell how they escaped from him after he had 

 imported them. 



"It seems, then, that this was an accidental introduction, 

 but that they have now become acclimated, and are spread- 

 ing and doing so much damaije as to cause verv irreat alarm. 



Disti'ibution. 



" The gypsy moth is abundant in nearly all parts of Europe, 

 northern and western Asia, and it even extends as far as 

 Japan. (In this country it has l>een found on\y in nineteen 

 cities and towns of Massachusetts. The whole of Medford, 

 Maiden and Everett and sections of Arlington, Melrose, 

 Somerville, Cambridge and Chelsea are thoroughly infested, 

 while in Stoueham, Winchester, Belmont, Saugus, Revere, 

 Lynn, Lexington, Swampscott, Wakefield, Burlington and 

 Charlestown they have been found more or less prevalent.) 



Food Plants. 



" The food })lants of this insect given in Europe are apple, 

 pear, plum, cherry, quince, apricot, lime, pomegranate, lin- 

 den, elm, birch, beech, oak, poplar, willow, hornbeam, ash, 

 hazel-nut, larch, fir, azalea, myrtle, rose, cabbage and many 

 others. Curtis, in his British Entomology, states that they 

 are sometim'es very destructive in gardens. Prof. W. P. 

 Brooks reported this insect as very abundant in Sapporo, 

 Japan, in 1883, and gave straw1)err3' as a food plant in 

 addition to those mentioned above. 



"(It has been ascertained by experiment at the office of the 

 Gypsy Moth Department in Maiden, Mass., that they will 

 feed on the following-named trees and plants : maple, elm.
