 both parties are obliged and enriched by the la- 

 bours of each other. To those who collect for 

 their friends, it is suggested, that they should 

 send them as many different sorts, and as 

 many of a sort as possible. And it may not be 

 useless to state, that those who oblige their 

 friends, whose only object is to collect the indi- 

 genous insects of Britain, should never, on any 

 account, send them foreign species, nor any 

 that are doubtful, by being imported with mer- 

 chandize, timber, plants, seeds, or otherwise, 

 without separating, and labelling them^ accord- 

 ingly. 



The entomologist would be gratified by hav- 

 ing the date, habitat, locality, or any other par- 

 ticu]ars respecting captured insects : it would 

 make the labour of the collector doubly valu- 

 able. The young student will of course keep a 

 regular journal of the times of appearance, habi- 

 tat, locality, food, &c. &c. of the insects which 

 he captures.
