INTRODUCTION. 



In presenting the Second Volume of our Magazine to the 

 public, we feel ourselves called upon to express our gratitude 

 for the liberal support which it owes to our Subscribers, 

 and for the valuable contributions with which they have 

 enriched it. 



We are particularly indebted to Mr. Ingall and Mr. 

 Raddon : the former engraves gratuitously for the Maga- 

 zine, and the latter has presented us this year with two 

 beautiful plates illustrating Deilephila Euphorbia. 



We are delighted to observe the increasing regard for 

 the study of insects, which is sufficiently manifested by the 

 Entomological Societies both at home and abroad. The 

 Entomological Society of London, warmly advocated in its 

 progress by this Magazine, has arrived at a degree of pro- 

 sperity never previously attained by an Entomological Society 

 in this country, although so many have been formed. The 

 first part of the Transactions of this Society has already 

 been published in a neat and compendious form, embellished 

 with seven copper-plate engravings, and is a work well worthy 

 the attention of entomologists. The Entomological Society 

 of France, contemporaneous with that in which this Maga- 

 zine originated, has continued publishing quarterly numbers, 

 keeping pace with our own, and containing papers of great 

 and rare merit. 



We trust that we have maintained the promises given in the 

 Introduction to our First Volume. We have alternated our 

 scientific essays with many of a popular character, or of 

 public utility. Our pages are free from party feeling; and in 

 our judgments we have been regardless of the approbation or 

 displeasure of others.
