preface. 



Ix issuing a second Report dealing with those Injurious 

 Insects and other animals, which have been forwarded to me by 

 various correspondents in the Midland counties of England during 

 1904, I am pleased to learn that' my efforts on behalf of agri- 

 culturists f fruit growers, etc., are appreciated. 



My hearty thanks are here tendered to the County 

 Council of Worcestershire for a Grant of 10 aiding the publica- 

 tion of this Report ; and to the Council of the Birmingham 

 Natural History and Philosophical Society, for a Grant to assist 

 my work in Economic Zoology. 



I have pleasure in acknowledging the kind assistance 

 given to me as regards the figures illustrating this work : to 

 the Controller of His Majesty's Stationery Office and the 

 Secretary of the Board of Agriculture I am indebted for their 

 courtesy in supplying me with electros of figures I, V, VII 

 VIII, XVII, XVIII, XXII, XXIII, and XXV, all of which 

 are from illustrations which have appeared in the Board's leaflets, 

 numbers 4, n, 15, 16, 30, 49, 53, and 75 ; to Messrs. Blackie 

 and Son, Limited, of Glasgow, for a similar favour in respect 

 to figures X, XI, and XIX; and to the Editor of the " Journal 

 of Horticulture," for the loan of figure IV.

 Observers, Messrs. Herbert Thompson and F. H. Brownhill.
