INTRODUCTION. 
Tur object of the present Supplementary Catalogue 
has been to give a complete list 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, 
&e., following the name of the species and its synonymes, 
and a description is given, if it appears to have been 
before undescribed.
