NATURAL HISTORY OF THE TINEINA. 



Those who are contributing; to the progress of this work are 

 naturally anxious to know to what extent their help becomes 

 serviceable, and with the view of notifying to my coadjutors 

 and others the amount of assistance I have received in the 

 past twelve months, the following Table has been prepared. 



I had made known some time since, that assistance in the 

 discovery and forwarding to me of new larvae would be 

 recompensed in a peculiar manner, namely, by presenting a 

 copy of the entire series of the Natural History of the 

 Tineina to any one who should first discover and commu- 

 nicate to me the transformations of twenty species with which 

 I was previously unacquainted. 



Now, in finding new larvae, there are three distinct steps 

 the discoverer has to make : — 



The first, and most important, is the discovery of the 

 larva. 



The second is the sending such larva to me, in order that 

 it may be duly figured and described. 



The third is the rearing of such larva through its trans- 

 formations, so as to ascertain the perfect insect produced 

 from it. 



It will frequently happen that, whilst one person will first 

 discover a new larva, some other Entomologist will be the 

 first to send it to me, and a third will perhaps be the suc- 

 cessful breeder. Hence the reward offered for the discovery 

 and first communication of the transformations of a new 

 species may have to be divided into three shares. Accord-
