 part of Europe."* 



An alarm took place as to the arrival of the pest 

 about the beginning of the present century, which was 

 proved to be unfounded by evidence that it was another 

 kind of fly.f The well-known passages in Kirby and 

 Spence's ' Entomology ' as to the destructive character 

 of this pest if it gained footing give a long range 

 onwards of won-observation from about 1815 to the date 

 of the edition of 1855 ; and in 1845 John Curtis notices 

 the attack as one which, as it had then been detected in 

 Europe, it was well to mention. And, in the summary 

 of information given in the * Eeport on Hessian Fly,' 

 brought out by the United States Entomological Com- 

 mission, 1880-82, I find these statements: "We know 

 that the Cecidomyia destructor does not inhabit England 

 or Scandinavia. "t 



Throughout this course of years we do not find any 

 authentic notice of the Hessian Ely occurring on our 

 side the Atlantic until possibly 1833 in Hungary, but 

 the first sure statement of the existence of the Hessian 

 Fly in Europe is considered to be that of " its discovery, 

 by Mr. J. Dana in 1834, at Mahon, Toulon, and Naples " 

 ("Hessian Fly not imported from Europe," * Canadian 

 Entomologist,' 1880). 



It is how known to exist in the South of France, Austria, 

 Hungary, and during the last seven years its presence 

 has been reported in Southern Russia, and its original 

 habitat is considered most probably to have been 

 Southern Europe and Western Asia, i.e., about the 

 shores of the Mediterranean Sea. (Report of U.S.A. 

 Comm., previously cited). 



The past summer has shown its presence amongst our- 

 selves. On July 27th the first specimens of the peculiar

J The name of Hessian Fly was originally given in consequence of the 

 fly being noticed about the same time with the arrival of the Hessian 

 troops in America. Those who wish to see the evidence by which this
