Geographical Distribution of Butterflies in Gt. Britain. 491 



extremity : three, however (Argynnis Euphrosyne and [A.] Selene, and 

 Syrichthus Alveolus), are not enumerated in a list of Irish butterflies (*) 

 with which we have lately been favoured by a correspondent. 

 The members of the " British Type "t are : 



Pieris Brassicae. 

 Rapae. 

 Napi. 



Anthocharis Cardamines. 

 Thecla Rubi. 

 Lycaena Phlaeas. 

 Polyommatus Alsus. 

 ,, Alexis. 



Argynnis Aglaia. 



,, Euphrosyne. 

 ,, Selene. 

 Melitaea Artemis. 



A few of these are local : Melitaea Artemis and Syrichthus Alveolus 

 affect marshy situations ; Polyommatus Alsus, Satyrus Semele, and 

 Thanaos Tages seem attached to a dry or calcareous soil ; Argynnis 

 Aglaia, A. Selene, and Thecla Rubi can hardly be called common. 



Small as this list is already, it is believed that by strictly following 

 Mr. Watson's definition several of its species might be transferred to 

 the next group. 



II. The "English Type" comprises twenty-four species, all of 

 which are more abundant in the Southern "Provinces," decreasing in 

 frequency northwards : 



Vanessa Cardui. 



Io. 



,, Atalanta. 



Urticae. 

 Satyrus Semele. 



,, Janira. 



,, ^Egeria. 



,, Hyperanthus. 



,, Pamphilus. 

 Thanaos Tages. 

 Syrichthus Alveolus.

 Vanessa Antiopa (E.) [S. I]) .\ 



Polychloros (E.). 

 C-album (E.). 

 Polyommatus Agestis (E.) [? !.].{ 

 Nemeobius Lucina (E.) [?S.]. 

 Argynnis Adippe (E. S.).

 Satyrus Megaera (E. S. I). 

 Pamphila Sylvanus (E.S.I). 

 Linea (E.S.I). 



The first four, though very local, seem to have their proper place p. 6024 

 here, and not in the "Germanic Type," as they do not evince a 



(#)This owing to westerly position, 

 t Thecla Quercus probably to be placed here. 



J Letters, &c., added in square brackets (here and elsewhere) were inserted 

 by Mr. More in pencil (W. F. K.). Said to occur in Ireland.
