PREFACE. 



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

 plete list of all the genera and species of Sphingidse 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.
