TO 



Dr. W. E. leach, F.R.S. &c. &c. 

 Sir, 



I may justly dedicate thcfullowiug pages to you, being 

 indebted for the most valuable part of their contents to your hiiuhicss and 

 liberality. I am happy in tlius liaving it in my power to acknouledge my 

 sense of the many obligations which I lie under to you : and at the satnc 

 time I trust the present work will be the means of aiding you in tlie very 

 praiseworthy cause in which you are engaged. It is also to be hoped that in 

 England, ere long, Entomology will stand on the same ground with Botany, 

 Chemistry, or Mineralogy ; and that your labours will eventually be as 

 duly appreciated in this country as they are now on the Continent. 



I remain, Sir, with the greatest respect. 



Your most obliged and obedient servant, 



GEORGE SAMOUELLE.
