differ from all the other butterflies in this respect, so far as known to 
me. The arguments of Mr. Wallace and Mr. W. H. Edwards as to 
the supremacy of Pafz/zo appear to me somewhat fanciful, but I agree 
that there 1s no good reason for altering the main Linneean arrange- 
ment of 1758, so far as a linear series is concerned. Only since I 
have demonstrated that the Parnassians are more specialised than the 
Papilionide, 1 would commence to arrange the Papilionides in a 
linear classification by the enumeration of the forms of the 
Parnassiidze, while I must insist that these two families are directly 
related. ‘They both have the curved internal vein of fore-wings and 
the suppressed vein VIII on secondaries. 
I venture to give here a list of the British day butterflies. I have 
taken asa basis the list published by Mr. Tutt in the “ Entomologists’ 
Record,” vol. vu, p. 300. The generic nomenclature is that corrected 
by Mr. Scudder, with the exception mainly of certain names in the 
Blues, where I follow Mr. Kirby. But I must protest, with Mr. 
Scudder, against the further use of the name ‘“ P/edezws,” and the 
crediting of such a name to Linné, in whose works it is not to be 
found. ‘The plural form “ //edezz” is not used by Linné in a sense 
corresponding with that of a genus. I have ventured to retain the 
name JZel/itea, since it dates from 1807, and cannot fall before 
Mehtea, which, according to Mr. Scudder (‘‘ Historical Sketch,” 
p- 215), dates from 1809. As between Lemonzas, Hubner, with the 
hardly certain date 1806, and JZe/ztea, we should prefer the Fabrician 
designation which has the sanction of established usage. It is to be 
regretted that there is no unanimity between Mr. Scudder and 
Mr. Kirby as to generic types in the Blues. The whole matter 
seems to depend on the type of /olyommatus, Latr., and Cupido, 
Schrk. The use of the former for corvzdon, and the latter for mznxzma, 
determines the use of ZLampides for boetica. Since Latreille figures 
coridon, and there is an argument, however “‘ far-fetched,” for Schrank’s 
intention, I follow Mr. Kirby.
