The Orders of Fabricius are equivalent usually to the 
primary groups of the Linnean Orders, and are regu- 
lated chiefly by the antenna:. 
In estimating the value of the above system, we must 
bear in mind that, according to the statement of its au- 
thor, it was intended to be partly artificial and partly 
natural : artificial as to its Classes and Orders ; natural 
as to its genera, species, and varieties 6 . He admitted, 
however, that natural Classes, &c. do exist; but he con- 
tended that artificial ones should be substituted for them, 
till further discoveries had cleared the way for their sa- 
tisfactory developement e . As therefore his system, in 
its primary and secondary groups, was confessedly arti- 
ficial, and the only use of an artificial system being to 
facilitate the study of any department of Natural History, 
its value must be estimated by the facilities it affords to 
the entomological student. But here, it must be allowed, 
that instead of enlarging the entrance to the temple of 
his science, it has made it narrower, and has placed 
most discouraging impediments in his way.
