Art. LXXVII. — Observations on the Analysis of ^ British Butterjlies^ 

 (Entomol. 265). By J. O. Westwood, Esq., F.L.S. 



Hammersmith, March 1, 1842. 

 Dear Sir, 



I crave a few lines' space in the next number of ' The 

 Entomologist,' to con-ect a few errors into which you have fallen in 

 your notice of ' British Butterflies and their Transformations.' 



1. Colias JEdiisa is not the Papilio Elect r a of Linnseus : see ' Brit. 

 But.' p. 130. 



2. The Linnasan name of Papilio Sinapis should not stand. The 

 insect has nothing on earth to do with Sinapis, or even with the tribe 

 of plants to which it belongs. 



3. Hubner divides our Vanessa into four (not three) groups, which 

 according to my views ought not to be adopted, being founded on cha- 

 racters far more trivial than those which characterize the groups of 

 our old genus Hipparchia. 



4. My new genus Lasiommata cannot become a synonyme of Hub- 

 ner's Pararge (not Pyrarge), as it also comprises his genus Dira. It 

 is not usual to call a compound of two things by the name of one of 

 them. Blue and yellow colours united form a distinct colour — green. 



5. Davus, Typhon, Polydama, &c. form the genus which I have
