Nat. Rouen, 1903, p. 97) that it occurs in the Pont de l'Arche district 

 " with the type but scarcer ; it is more often taken at Deux-Amants, 

 where, in the forest, it is particularly beautiful; it has also been taken 

 at Chateau-Gaillard, near Andelys, where the type is extremely 

 abundant." One suspects the record of Neustadt and Kornatzki who 

 speak of it as " common " in Silesia.

 I should not be disinclined to consider it to be the ? of endymion, if it were not 

 that the latter was one of those species in which the orange is absent on the under- 

 side of the hind wings (Bergstrasser). 



Bergstrasser figures (Xow., iii., pi. lix., figs. 5-6, 7-8) two 2 A. cori- 

 don under the name corydonis. The first, represented in figs. 5-6, is 

 just typical 2 coridon, the second, represented by figs. 7-8, is the oldest 

 picture of the fairly common obsoletely-marked underside form, in 

 which only tbe discoidal spots and marginal lunules remain. This 

 form was not figured again for about 45 years, when Hiibner gave an 

 illustration of it {Eur. Schmett., pi. 167, figs. 830-831) and renamed it 

 cinnus. It was correctly referred, under this name, to A. coridon 

 as an aberration by Boisduval, Duponchel, Heydenreich, Doubleday 

 and Westwood, Herrich - Schaffer, Meyer-Dur, and Kirby, in fact 

 by all reputable authors until 1871, when Staudinger, evidently
