same colour as the feet. Above the lateral line are placed the 
stigmata, which are black and very small, not well seen without 
the aid of a glass. The larva lives on the pods of Astragiilus 
Phijsodes, L. ; it ijrobably has the same habits as that of L. Bcetica.”

Small butterflies with the hind wings generally denticulated 
on the hind margin, near the anal angle. The colour of the wings 
is usually brilliant orange-red, with a metallic coppery lustre ; 
sometimes it is dark brown, and occasionally the wings are shot 
with violet. The upper surface has generally rows of black spots, 
though in some species the males have the wings unspotted. 
Beneath, the colour is grey, varying from blue to warm brown in 
tint, always with numerous black spots which are without ocelli. 
The females are larger than the males, and usually more spotted 
with black. The eyes are not hairy, as in Thestor ; the antennge 
are long, with an elongated club. 
The Larvse have the shape of those of the Lijccenidce generally 
— being woodlouse-shaped, with small and retractile head. Their 
food-plants are usually, but not exclusively, different species of 
Rumex. 
The butterflies frequent meadows, woods, and marshes ; and 
some species are found only in mountainous districts. 
Though this genus is represented in almost every part of the 
world, the more temperate regions are where the species most 
abound ; hence it is that a large proportion of these are found in 
Europe.
