DEDICATION. 



To the late John O. Westwood (First Hope Professor of Zoology at the University of Oxford), M.A., F.L.S., 

 etc., etc., with many other distinctions and memberships of learned societies in all parts of the civilised world, which 

 were the natural results, fully merited, of the enormous amount of valuable work in many branches of Zoology and other 

 subjects, which he accomplished during a long and industrious life — to the memory of this great and faithful master of 

 Natural Science, I feel it an honour to dedicate this volume of my monograph. 



Professor Westwood's writings and drawings illustrative of every order of insects, in addition to his palseographic 

 and other works, are well known and highly valued throughout the world of Zoological and Archaeological Science. They 

 are so numerous that a list of them would fill a small volume ; and up to the period of his death he was as unwearied in 

 giving to the world the results of his investigations, as he had been in the earlier and middle portions of his long and 

 useful life. If he had produced only his great work "An Introduction to the Modern Classification of Insects," which 

 was published in two closely-printed volumes in 1839-40, the entomological world would have been laid under a deep debt 

 of gratitude to him ; for the work was such a masterpiece of learning, as to constitute it a valuable encyclopaedia in 

 itself of the subjects of which it treats. We need another man, gifted with Westwood's abilities and enthusiasm, to sup- 

 plement his labours, by giving us two or three additional volumes, constructed on the same plan, in which should be in- 

 corporated the wonderful results of the investigations in Entomology of the many workers among all nations during the 50 

 years that have passed away since Professor Westwood wrote the last line of his great treatise. Such a work must be 

 undertaken sooner or later — the sooner the better. Even then, amongst so much that has been splendidly 

 accomplished by others, his contributions quite down to the year of his death will be found to be so numerous> 

 and so valuable, as to bring him into continual remembrance. His work will be his monument while Entomology 

 is studied ; and no words of mine, or of others, are needed to enhance his fame. 



One of the rewards of those who strive to enrich the world with their talents, is that, while " their works do 

 follow them," they also remain with us and continually remind us of what it is possible for an earnest worker in any 

 department of heaven-inspired labour to be to his day and generation, and to the generations that are to come. 



And now, with the highest sense of the honour, I remind myself that Professor Westwood was one of 

 the earliest subscribers for a copy of this monograph ; that he took great interest in its progress, as his letters to me 

 evidence ; and that he willingly accepted my dedication of it to him. 



Therefore, whilst I regret that he was not spared to see its completion, I am glad of the privilege of dedicating 

 this First Volume to his memory, with the earnest hope that the beautiful Science which he adorned and advanced by 

 his gifted labours, may attract an ever-increasing number of equally gifted and devoted workers in the future of Zoologi- 

 cal investigation.
