Characters. — Larvse fusiform, tapering towards the extremi- 
ties, smooth or pubescent ; very rarely, and only in some exotic 
species, hairy, and never spiny. The head is large and globular. 
The larvae of the European species feed on low-growing plants, 
chiefly those belonging to the orders Leguminosce, Malvacece, and 
Labiatce, and on grasses. They are in the habit of rolling them- 
selves up in leaves after the manner of the larvae of the heteroceous 
group Tor trices, spun together in a sort of cocoon. 
Pupae without angles, and tapering at the extremities, espe- 
cially at the caudal end ; they are never suspended or succinct, 
like those of the groups of butterflies already described, but are 
often enveloped in a slight cocoon made of loosely-spun filaments 
of silk. 
Imagines, small butterflies, the head large, almost as wide as 
the thorax, the antennae set widely apart from each other at their 
base. They have a small tuft of hairs at their base, the shafts are 
short, the clubs thick and often arched, and sometimes furnished 
with a terminal hook. All the four legs fully developed in both 
sexes ; the posterior tibiae furnished with four spurs in the majority 
of the European genera, but in Carterocephalus they have only two.
