62 BUTTERFLIES OF THE RIVIERA 



LARVA. On Plantago, in April. 



VARIETY. v. Varia. 



This is the true Alpine variety of the species, and is 

 found at a higher elevation than the type. It is smaller 

 than Parthenie and the female is darker, and clouded 

 with greenish black. Both sexes have the central row 

 of spots on the u.-s. of the h.-w. white, instead of 

 yellow. 



I have found both type and variety, also & forma 

 intermedia, or intermediate form of the two species. 



It is common at these high elevations.
