MEMBRA ClDAE. 
265 
Short Catalogue of the Sub-family : CENTROTIDAE. 
The annexed list, partly compiled from a more extended catalogue communicated 
by Mr. W. F. Kirby, must lose some of its usefulness by its necessary abridgment. 
It here states in alphabetical order the genera cited or erected by certain authors 
mentioned up to the present date. It also gives examples in a general way of 
species, many of which may be examined in the British Museum of London, but the 
number of species mentioned by authors is much larger than the limits of this 
treatise will allow to be given in full. 
An estimate of the named species of Membracidre, amounting to more than twelve 
hundred, is given in the introduction to this Monograph, but this estimate must be 
far below the limits actually existing in tropical and temperate climates. 
The alphabetical arrangement shows that no systematic series has been adopted 
in it, though some attempt has been made in the body of this work to construct such 
from the general external characters of the winged insects. 
In this subjoined list, as before noted, the habitats are given with the species, 
which are mostly typical ; but this is not meant to imply that the examples men¬ 
tioned are confined to the locality enumerated, nor of course to the genera or species 
there named 
Zoological genera descriptive in their very names are becoming more and more 
difficult to be found, they having been long since preoccupied. Some of the genera 
here proposed will be thought barbarous and unclassical, but a name, used simply as 
a label, has certain conveniences for future use, as it may not clash in the description 
of future species with possible immaterial differences, whilst showing characters which 
are clearly generic.
