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 Lepidoptera into groups d : and in the Monogra- 

 phia Apum Anglite, the characters exhibited by the va- 

 rious groups into which Linne's genus Apis was resolv- 

 able, as to the neuration of their wings, w r ere 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-
