vi PREFACE 



not systematic but aimless work that I deprecate 

 -work which springs from no real curiosity about 

 Nature, and attempts to answer no scientific questions. 

 I have great pleasure in acknowledging the advice 

 and contributions of several friends, and especially of 

 Messrs. W. F. Baker, T. H. Taylor, and J. J. Wilkinson. 

 The drawings made by Mr. Hammond, in most cases 

 direct from the Insects, are a valuable feature of the 

 book, and I could say more in their praise if they did 

 not speak for themselves.

 LEEDS, February 1895. 



Advantage is taken of a reissue to correct the 

 errors which have come to the author's knowledge, 

 and to add a few Additional Notes (pp. vii-viii).
