Notes on the above Synonomy and Bibliography. — Although containing 

 over 230 references, the Bibliography is incomplete. The pest is so well 

 known, so widely distributed, and so destructive that it has attracted much 

 attention for more than 50 years ; and in consequence it has been often dis- 

 cussed in our economic entomological literature and in Agricultural periodi- 

 cals. I have had access to nearly all of the strictly entomological publica- 

 tions of the United States, but I have seen only a few complete files of agri- 

 cultural publications (the Country Gentleman is the only weekly general 

 farm paper among these). The reports in these periodicals are often valua- 

 ble, as they usually give the results of experiments with various substances ; 

 thus it is to be regretted that this part of the bibliography could not be made 

 more complete. It is also incomplete in respect to foreign publications as 

 only those are included to which I have had access. I believe, however, the 

 bibliography contains nearl}' all of the more important articles on this pest 

 in the world's literature. 



Economic writers on the pest have heretofore paid little orno attention to the 

 systematic phase of thesubject. Nearly every economic writer, whether Euro- 

 pean or American, has used, scarcely without question, the naxsx^ brassicce , 

 given to the insect by Bouche in 1833 ; while Schiner is the only Dipterolo- 

 gist, so far as I know, who has expressed any opinion on Bouche's species. 

 However the flies, which I bred in large numbers from Cabbage Maggots, 

 were determined by Mr. Meade as Phorbia floccosa Macq. Coupled with 

 this fact, I soon found that all the specimens of Cabbage, Cauliflower, Radish, 

 or Turnip Maggots or Flies to which I could get access through entomologi- 

 cal friends,* belonged to this same s^^cx^^— floccosa. These facts at once 



♦Messrs. G. C. Davis, J. Fletcher, L- O. Howard, and Dr. Lintner have kindly sent me 

 their material in this line for study. This has enabled me to settle many disputes and un- 

 solved questions.
