It Ikis been a source of no small CTatification to the writers of these Reports to receive 

 so many kind exjiressions of appreciation of their labours. The favourable notices toi, that 

 have appeared in many Kniilish and American publications, afford them mucli encouragement 

 in the pursuit of their Entomolopcal labours, to which thej' regret they are unable to dc 

 V jte more than a small proportion of their time : each of them being necessarily engaged in 

 other deeply engrossing pursuits, and having but little leisure at his command. The writers 

 would again remind their readers that they are responsible only for their individual portions 

 of the Report.
