PREFACE TO THE SECOND EDITION. 
The enthusiastic reception which “ The Entomologist’s 
Annual” has met with, from all classes of Entomologists, 
not only renders its continuance in future years a matter 
of certainty, but has rendered it necessary to bring out a 
Second Edition of that “ for 1855.” 
Of course, if the demand that has arisen for the book 
could have been foreseen, a larger “ first edition ” would 
have been printed, but, starting with so few data to go upon, 
I was as much mistaken, in the probable success of the un¬ 
dertaking, as were the originators of railroads respecting the 
probable speed to be obtained by locomotive engines. 
The object of this Annual is to record systematically the 
discoveries of each year. Every year new species are being 
added to our Fauna, and that these should be systematically 
chronicled is, in a science so vast as Entomology, of very 
great importance. That this may be efficiently done, it is 
essential that the writer, on each group or order of insects, 
be selected from those best acquainted with the subject. 
The present volume contains only three Orders: the Le- 
pldoptera, which, with the kind assistance of Mr. Double¬ 
day and Mr. Douglas, I have worked up myself; the 
Hymenoptera, for which no more able and thorough 
writer can be found in England (*/in Europe) than Mr. 
Frederick Smith, one. of the Assistants in the Zoological
