CHAPTER X. 
THE SCIENTIFIC ARRANGEMENT AND DESCRIPTION 
OP THE GENERA, WITH LISTS OF OUR NATIVE SPE¬ 
CIES AND AN ACCOUNT OF THE HABITS AND ECO¬ 
NOMY OF THE INSECTS, WITH INCIDENTAL OBSER¬ 
VATIONS SUGGESTED BY THE SUBJECT. 
I now proceed to the treatment and description of the 
genera severally, and the enumeration of the species in 
due scientific consecutive order. 
The generic names adopted are those of the first 
describers of the genera; but the generic characters 
given by them could not be employed, they having been 
usually framed to suit special purposes. 
All the generic characters introduced into this work 
are therefore quite original, and have been made from 
a very careful autoptical examination of the insects 
themselves. 
The synonymy added to the lists of species is limited 
to the species described in Mr. Kirby’s work, where he 
is not the first describer, or to those of such other 
English works wherein the species may have been de¬ 
scribed in ignorance of its previous registration. 
The observations appended, wherein the habits of the 
insects are described, will be found to embrace discur-
