PREFACE. 



The object of the present Catalogue is to give a com- 

 plete list of all the genera and species of Pyralides known 

 to exist in the different collections. The letters a, b, c, 



I &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 



1 therefore desirable to be procured for the collection.
