Note. — “ I liave found this species in Madeira in 1879. It is 
common in gardens in February. It flies like Atalanta, and is often 
seen settling on a path or road with expanded wings, basking in the 
sun, in which position it is easy to aj)proach. The larva lives on 
nettle {Urtica dioica), and resembles that of Vanessa Atalanta; it 
lives, like Atalanta, in a rolled-up leaf, in which it changes to a 
pupa. I have now an empty pupa-case before me ; it resembles 
that of Atalanta, but is perhaps a little lighter in colour. I have 
found the larva and pupa in April.” — T. D. A. Cockerell, ‘ Science 
Gossip,’ July 2nd, 1883.

towards the base of all the wings. Fore wings with a marginal

centre of the wing placed irregularly. Hind wings fulvous along 
the hind margin, basal and central portion fuscous ; there is a 
submarginal row of black spots. Under side somewhat as above, 
but lighter ; there are some black transverse lines in the discoidal

distinct, but resembles Thore or Frigga perhaps more than any 
other Argynnis.
