from November till March. The pupa is reddish brown, the wing- 
cases yellowish. I have found this species at Cannes and Hyeres. 
This species usually appears on the wing in March, about the 
15th, and after a fortnight few good specimens are to be seen. 
The time of appearance, however, varies much ; in forward seasons 
it appears in February, but in 1864 and 1865 it was not on the 
wing until April.” 
h. Ochracea, Stauch, differs from the type in having the ground 
colour dark ochre-yellow. This form occurs in the South of Europe 
and Asia Minor.
