PEARL SKIPPER. 
the under side. The female is usually larger than 
the male, and destitute of the discoidal black line 
which is invariably a sexual distinction. In this 
sex also the spots are whiter, and in the anterior 
wings they form an irregular band extending across 
the surface ; while in the hinder pair they are edged 
>vith black and somewhat notched behind. 
The caterpillar is obscure green mixed with rust 
red, and having a series of black dots on the back 
and sides. The head and neck are black, the latter 
with a white ring. On the continent it is said to 
feed on the Coronilla varta, but in this country 
probably has recourse to diadelphous plants or 
grasses. 
By no means so generally distributed as the pre- 
ceding, but found in some plenty in certain places. 
Miss Jermyn mentions chalky soils near Lewes in 
Sussex, as having afforded it plentifully ; it like- 
wise occurs near Dover, in the neighboiurhood of 
London, in "Wiltshire, in Eoxburgh and Drunfries- 
shire, &c. 
Besides the above species of Hesperidas, it is now 
ascertained that the Pamphila Actwon has occa- 
sionally been found in the south of England. Not 
having seen examples of this insect, we subjoin 
Godart’s account of it ; from the localities he cites 
for it in France, it seems no way improbable that 
it should inhabit some parts of Britain.
