Colias edusa. CLOUDED YELLOW. 



1. It is now, I think, quite settled that this butterfly is 

 an immigrant, and that all the Spring specimens are aliens ; 

 the second brood appearing in August is probably the 

 offspring of the Spring immigrants. 



Its head quarters in England are the South and South- 

 east coasts, but it is occasionally common in the Midland 

 counties. It occurs in the South of Ireland, and sparingly in 

 the South of Scotland. Very irregular in its appearance. 



He! ice is a variety of this species. 



2. -Non-such Trefoil (Mcdicago lupulina), Lucerne (M . 

 sativa), and two species of Clover (Tri folium pratcnsc and 

 T. rcpcns). 



3. August to October. 



4. Clover and Lucerne fields, railway banks, dry 

 flowery meadows, open downs, and grassy cliffs. 



Gonoptenyx nhamni. BRIMSTONE. 



1. A common and generally distributed species through- 

 out England, but most abundant in the South. It is 

 occasionally met with in the South of Ireland ; unknown in 

 Scotland. 



2. Two species of Buckthorn (Rhamnus frangula and 

 R. catharticus] . 



3. July to August, but occurs throughout the year.
