482 HISTORY OF ENTOMOLOGY. 
Our learned author in subsequent works has stated 
every circle to be resolvable into two superior groups, 
which he denominates normal or typical, and three infe- 
rior ones, which he calls aberrant or annectent a . 
Before I conclude this account of the various general 
systems that have distinguished the different entomolo- 
gical eras, I must say a few words on those 'partial ones 
which have been founded on the neuration of the wings 
of insects. Frisch, who died in 1743, attempted some- 
thing in this way b : Harris, in his Exposition of English 
Insects published in 1782, had arranged his Hymeno- 
ptera and Diptera according to characters derived from 
this same circumstance c : Mr. Jones in the Linnean 
Transactions had made good use of it in dividing the 
Diurnal Lepidoptcra into groups d : and in the Monogra- 
phia Apum Anglicc, the characters exhibited by the va- 
rious groups into which Linne's genus Apis was resolv- 
able, as to the neuration of their wings, were described e . 
But M. Jurine was the first Entomologist who made that 
circumstance the keystone of a system ; which indeed he 
restricted to Hymenopterous and Dipterous insects, but 
which might be extended much further. As this system 
has been before sufficiently enlarged upon f , I need here 
only mention it. 
To particularize the various entomological works in 
every department of the science, that have appeared since 
the commencement of the era of Fabricius, would re-
