speedily as possible. This basis is established for us by the 

 International Rules, and we are heartily in favor of working 

 out the standing of our genera according to these rules, accept- 

 ing whatever radical changes they produce, and turning a deaf 

 ear to the cries of those who would continue to make personal 

 opinion their ultimate guide. 



ASCIID^. 



AsciA Scopoli Logotype Papilio monuste Linn. 



1777. Scopoli, Int. Hist. Nat. 434; Crataegi, napi, sinapis, monuste, polybe. 



1872. Scudder, 4th Rept. Peab. Acad. 61, cites monuste as type. 



1875. Id., Hist. Sk. 121-2, confirms this citation. 



1918. Hampson, Nov. ZooL XXV, 385, cites crataegi as type. 



Owing to Scudder 's action in 1872 this genus must be regarded as 

 valid, and will replace Pieris in our fauna. As a result of this the 

 family name becomes AsciidcB. Hampson uses cratcBgi as type, following 

 the first species principle, which is not permissible under the Inter- 

 national Rules. He arrives, however, at the same conclusion regarding 

 the family name, which he spells Asciadce. 



SATYRID^. 



Megisto Hbn. Logotype Papilio eurytus Fab. 



1818. Huebner, Verz. bek. Schmett. 54; Cymelia (euritus), argante, eiiridice 



{canthus, camerta), acmenis. 

 1868. Butler, Cat. Satyr. B. M. 14, Cites eurytus (euritus, cymelia) as type. 

 ^1872. Scudder, 4th Rept. Peab. Acad. 27, follows Butler. 



^1875. Id., Hist. Sk. 213, says that this was incorrect because "eurytus is 

 strictly congeneric with penelope, the type of Cissia," and cites acmenis 

 as type. 



Butler's citation of eurytus was valid and Scudder's later citation 

 of acmenis ultra vires. As a result we must use Megisto to replace Cissia, 

 type penelope. 



Argus Scopoli. Logotype Papilio eurydice Joh. 



1777. Scopoli, Int. Hist. Nat. 432; a heterogeneous group including eurydice, 



1872. Scudder, 4th Rept. Peab. Acad. 27, cites eurydice as type. 



1875. Id., Hist. Sk. 118, discards this genus because of its original hetero- 

 geneous nature. This may have been a desirable course, but it seems 

 entirely indefensible, since the genus had already been given a valid 

 type and definite generic usage in the modern sense. 



1888. Id., Butt. New. Eng. I, 187, under Satyrodes, cites Argus Scudder (not 

 Scopoli). 



We see no way to avoid using this genus in place of Sat3Todes. 



Heliconius Linn. Logotype Papilio psidii Linn. 



1758. Linneaus, Syst. Nat. Ed. X, 458. Many species, including Danaidse, 



Parnassiince and HeliconiincB (of authors). 

 1810. Latreille, Consid. Gen. 440, cites polymnia and horta as types. Neither 

 of these species belongs to Heliconius Auct.
