The fore wings of the female have a broad blackish

 of dark spots along the outer margin. The ground 

 color is usually a lighter blue on the females than on

 and the spots on the basal part of the hind wings are 

 enlarged and run together so as to form a more or less 



complete triangular discal patch, as shown 

 in Fig. 78. This and Marginata are the 

 smaller forms. 



Form Marginata has the terminal band 

 of the under side as in Lucia, but the 

 spots on the basal part of the hind wings 

 do not coalesce. 



Form Violacea has the dark points 

 and crescents on the under side of the 

 wings quite prominent, but they do not coalesce, either 

 in the outer border or in the basal portion. The black
