PREFAC E . 
The object of the present Catalogue is to give a complete 
list of all the genera and species of Crambites, Tortricites and 
Tineites known to exist in the different collections. The 
letters a , b , c , &c., after the species, denote the specimens now 
contained in the British Museum, followed by the habitat and 
the mode in which each of them was obtained, and the absence 
of these letters indicates the species which are desiderata, 
and therefore desirable to be procured for the collection.
