Europe confined to the Pyrenees, the Tyrol, and Switzerland. In 
the latter country it is common, hut always occurs in considerably 
elevated places. I have usually seen it at an elevation of not less 
than 5000 feet. PI. XII., 2. 
Laeva green, with a white stripe on each side, on which are 
yellow spots dotted with black. It feeds on Legimiiiosie, chiefly of 
the genus Vida, in June and July.

Expands on an average 1-75 in., sometimes reaching 2 in. 
Wings sulphur-yellow. Fore wings with a black discoidal spot, 
and a black hind-marginal band enclosing a row of conspicuous 
yellow spots, and ending rather abruptly, so as not to reach the 
inner margin ; as it approaches the latter it gradually becomes 
narrower, being widest at the costa. Hind wings yellow, blackish 
at the base ; faint traces of a black band are seen on the anterior 
part of the hind margin, and there is a large discoidal spot of a 
bright orange colour. The female exhibits the dimorphism so 
common in this genus, often having the wings nearly white, 
instead of yellow. Under side : — Fore wings yellow, darker at the 
apices ; a row of five or six black spots runs parallel to the hind 
margin ; the discoidal spot is black. Hind wings deeper yellow, 
with a large pearly discoidal spot surrounded by a dull red ring, 
and having a smaller spot similar in character placed above it. At 
the base of the wing is a dull red mark, which is not found in the 
preceding species. Parallel to the hind margin is a row of dull red 
crescentic spots, with their concave sides outwards, and a con- 
spicuous narrow reddish spot on the' costa. Head, prothorax, 
antennae, and legs dull red ; fringes of hind margins pink.

Times of Appeakance. — From July to the end of September; 
and again in the spring, after hybernation. 
Habitat. — The greater part of Europe, but not the northern 
regions ; the extra-tropical part of Asia and North Africa. On the 
Continent it is a very common insect, and may be seen throughout 
the summer in Germany, Switzerland, &c., frequenting clover
