INTRODUCTION 



The object of the present Supplementary Catalogue 

 has been to give a complete Ust of the specimens of 

 Homopterous Insects contained in the collection of the 

 British Museum, received since the printing of the former 

 Catalogue, indicating at the same time the peculiarities 

 of each, as regards variation of- character, locality, and 

 the source from whence it has been derived. With this 

 view, the different individuals of each species contained 

 in the collection are indicated by the letters a, b, c, 

 &c., following the name of the species and its synonymes, 

 and a description is given, if it appears to have been 



before undescribed.
