noticed hitherto. They have a thick body, a large and strong 
head, and the antennae swollen and spindle-shaped at their ends, 
or hooked. Their legs are well developed ; the hind ones are 
particularly strong, and the others are spined. The wings are 
small in proportion to the size of the bodies, in these Lepidoptera , 
the metamorphoses of Pamphila aracynthus. 
and they are generally grey, brownish, or fawn in colour. The 
butterflies have a curious and hesitating flight, and are very pro- 
perly called Skippers. The caterpillars differ from those of the 
other Lepidoptera already noticed as much as the butterflies do ; 
they have a long and thin shape, with a large rounded head, 
and they are remarkable for their brisk movements. 
In order to hide safely, the caterpillars roll up the side of 
a leaf, and fasten it with some of their silk. Before the first 
metamorphosis they choose a safe hiding-place ; then they attach 
themselves by their extremity like the other diurnal forms.
