VARIETIES. 
a. Syngrapha, female, Keff. Stett. Ent. Zeit., 1851, 308; ab. 
foem., maris colore, B. Gen., p. 12. This is a variety of the 
female in which the wings are more or less entirely suffused with 
blue, as in the male. It thus corresponds to the variety Cerouus of 
the last species. PI. XXVI., 7. 
Habitat. — The Pyrenees. 
h. Appenina, L. Is., 1847, p. 148. 
Habitat. — Italy. 
c. Hispana, H.-S. 500-1. — Arrayonensis, Gerh. 
Habitat. — Northern and Central Spain. 
Both these forms are local mountain varieties, and differ 
principally in being much paler than the type, between which and 
the following they form transitions. 
d. Albicans, H.-S. 494-5; Mill. i. 159, pi. 4, 2. In this 
remarkaljle variety the wings of the male are entirely dull white, 
without any trace of blue. PI. XXVI., 8. 
Habitat. — Andalusia.

Fringes of all the wings white. Male bright blue, with a 
narrow brown hind-marginal border; along the hind margin of the 
hind wings is a row of not very distinct brown spots. The female, 
aliove, very closely resenil)les that of L. JcariiH, but the wings are 
darker l)rown, the orange Itand on the fore wings less distinct, and 
the white marginal fringe broader. Beneath, the wings somewhat
