PREFACE 



The object of the present Catalogue is to give a list of 

 the Specimens received by the Museum or described by 

 Naturalists since the publication of the former Parts. The 

 letters a, b, c, &c, after the species, denote the specimens now 

 contained in the British Museum, followed bv the habitat and 

 the mode in which each of them was obtained ; the absence 

 of these letters indicates the species which are desiderata 

 for the Entomological collection.
