PEE FACE. 



The volume now issued as the Second Keport on Economic Zoology 

 contains a large part of the information furnished by the Director 

 of the Natural History Departments of the British Museum to the 

 Board of Agriculture and Fisheries between November, 1902, and 

 November, 1903. It also contains the replies given hj the Zoological 

 Department to other correspondents in connection with Economic 

 Zoology, as well as special notes and some longer papers dealing with 

 the subject. 



Mr. Frederic V. Theobald has carried on the whole of tliis worl^ 

 and drawn up the Eeports now printed. He has been assisted in 

 preparing certain replies to the Board and to other correspondents 

 by Messrs. C. O. Waterhouse, M. ii. Oldfield Thomas, F.E.S. and 

 R. 1. Pocock, of the Staft' of the Zoological Department of the Museum. 

 Mr. C. 0. Waterhouse lias carei'ully r<'ad the proof-sheets <tf the 

 present volume. 



Special acknowledgments are due to tliose naturalists not on the 

 Staff of the Museum who liave assisted Mr. Theobald in accomplishing 

 the work set forth in these Reports. To Mr. Rol)ert Newstead we are 

 indebted for valuable help in naming insects of the family Coccidy, 

 on whicli he is the leading authority, as also for his share in tbe 

 paper on Egyptian Scale Insects (p. 185), which is mainly from liis 

 pen. Mr. Albert Michael, Mr. Distant, Dr. Nalepa, of Vienna, 

 Professor L. 0. Howard, of Washington, and Professor Neumann, of 

 Toulouse, have also, in their several specialities, given us kind ami 

 valuable assistance. 



The amount and variety of the woik which it has been 

 Mr. Theobald's duty to put through have been very large, whilst the 

 energy and ability which he has l;rought to bear on the task deserve 

 special recognition and appreciation.
