" Lycana amyntas and coretas. Two very distinct seasonal forms of 

 Lycana amyntas occur in Brittany. The spring form is smaller than 

 the summer one. The female of the former has the wings on the 

 upper surface more or less dusted with hlue, whilst the upper surface 

 of the wings of the female which emerges in the months of July and 

 August is quite black, the hind wings having a small orange spot im- 

 mediately above the tiny tail. In Brittany both the spring and 

 summer forms have two or three small yellow marginal spots on the 

 under side, which are more strongly marked in the summer race. 

 Finally, in Brittany the two seasonal forms of amyntas present a 

 striking peculiarity in respect to their habitats. In May this Lycana 

 occurs in the meadows and grass rides in the woods, while in July it 

 is practically confined to the heaths where the heather is high. I am 

 inclined to consider that the two seasonal forms of amyntas occur in 

 the whole of the west and south-west of France as they do in Brittany. 



"In the Eastern Pyrenees, where we have collected more than sixty 

 specimens, some in the spring and some in the summer, the female is 

 invariably black above, without the orange marginal spot on the hind 

 wings. Both sexes, moreover, lack the yellow marginal spots on the 

 under side. As in Brittany, the summer is generally larger than the 

 spring form, and sometimes the tail of the hind wings is wanting. 

 This is the Lycama coretas of Ochsenbeimer and Gerhard. I am inclined 

 to think that coretas is a distinct species from amyntas. I have speci- 

 mens of both amyntas and coretas from the Basses Alpes. In the 

 neighbourhood of Digne these two Lycsenas are found in the same 

 localities, but in the Eastern Pyrenees (Villefrauche-de-Conflent and 

 Vernet-les-Bains) and in the neighbourhood of Rennes they seem to 

 inhabit different localities. 



" Amyntas is distributed over Manchuria, China (Chang-Hai), and 

 in Japau. Coretas, however, has not been found in Asia. 



"From Yunnam I possess a new variety (or possibly species) of 

 which the male has broad black margins to the fore wings. 



" In France it would be interesting to record the localities where 

 amyntas and coretas occur together and separately. I appeal to the 

 kindness of the readers of ' La Feuille ' to inform us on this point. 



" Hubner has figured under the numbers 319, 320, and 321, under 

 the name of tiresias, coretas of Ochsenheimer and Gerhard. 



" The same author has figured amyntas forma aestivalis under the 

 numbers 322, 323, and 324." 



The names used in the above article are not those of the last 

 edition of Staudinger and Kebel's ' Catalogue,' in which work 

 tiresias of Hubner is given as a synonym of polysperchon, Berg. 

 If this view be correct, tiresias must be a name for the form with 

 the yellow marginal spots on the under side, the spring genera- 

 tion of argiades = amyntas, and not of coretas of Ochsenheimer. 



Mr. Oberthiir refers to two most interesting but quite different 

 points, the first being that the spring and summer broods of 

 argiades = amyntas occur in quite different localities ; and the 

 second, that argiades = amyntas is a distinct species from coretas. 

 The occurrence of the two broods of the same species of butter-
