THE following pages are ail endeavour to give a 

 short account of the new crop-pest which has appeared 

 amongst us, so far as we have as yet traced its history 

 here. For the methods by which its ravages may be 

 counteracted we are under obligations to the observers, 

 and to the agricultural entomologists of other countries, 

 where these have long been studied, and especially to 

 those of the United States of America ; and in quoting 

 from their works, and to some slight extent making 

 use of their illustrations, I have endeavoured fully to 

 acknowledge the source, and also to separate these 

 observations clearly from the British experiences of the 

 past autumn. 



I beg also to express my sincere thanks to the eminent 

 entomologists, whose names I have given in the following 

 pages, for their kindness in examining into and con- 

 firming my identification of tho attack as that of 

 Cecidomyia destructor at a time when the task of identi- 

 fication and bringing forward a crop injury never before 

 known in the country was a most anxious responsibility 

 which they assisted greatly to lighten.
