OF THE DIURNAL LEPIBOPTBBA.

datse, nee metallo nobili ornatae;" and it will conveniently illus- 

 trate the utter wortlilessness of Scopoli's genera. Taking the 

 first six species in Scopoli's first section, "simpliciter ocellati," 

 we find they belong to the six foUowing genera— il/or;?/io, Far- 

 nassius, Tenaris, Colias, YptUma, Maniola. 



We will now pass on to Tabricius, who published his last 

 work on general entomology, the ' Entomologia Systematica,' 

 in the year 1793. In this work ho divides the Linnean genus 

 JPapilio as follows : — 



Papilio Equites Trojani. 



• Achivi. 



Festivi. 



• Nymphales. 



Hesperia (=Plebeii, Linn.). 

 Kurales. 



Papilio Heliconii. 



Parnassii. 



Danai. 



Satyr i. 



Urbicolae. 



If a later author has an indefeasible right to restrict the use 

 of a term, we are bound to retain the name Danaus for the 

 modern geuus JPieris, as Fabricius restricted the term Danai to 

 the Danai candidi of Linnseus, separating the Danai festivi, 

 which include the types of our modern Danaidcs, under the name 

 oi festivi. But it i^ not desirable to push a principle to its ulti- 

 mate limits in such a case as this. 



The next important systematic work was Schrank's ' Fauna 

 Boica,' published in 1801. His divisions of the butterflies, with 

 their Linnean and modern equivalents, are given below.
