HESPERIIDAE 
half are pale ochreous. The antennae are black and fulvous 
above, cream colour below, and the tips are deep black, which 
is the chief distinctive character of A . lineola ; the antennae 
tips in A. sylvestris (=thaumas) are orange-red. 
( Under Side.) The wings are fulvous, with a blackish 
cloud from the base along the inner margin ; the apex is 
pale ochreous ; the hind wing is pale fulvous along the costa 
and pale ochreous below the second median nervure; the 
rest of the surface is greyish-ochreous. Over the eye is a 
tuft of black curved hairs. The ventral surface of the body 
is ochreous-white. 
Life of Imago. A. lineola is comparatively short lived, its 
life probably not exceeding eighteen or twenty days. 
Aberration. Considerable aberration occurs in the depth of 
the ground colour and in the extent of the marginal borders ; 
in some the latter forms only a marginal line, while in others 
it is strongly suffused with the ground colour. Occasionally 
straw-coloured examples are met with. 
Genus ADOPOEA, Billberg , 1820 
THE LULWORTH SKIPPER 
Adopoea acteon (Rott., 1775 =actaeon). 
(Plate XXXI, facing page 340) 
This locally-abundant little butterfly was unknown as a 
British species prior to 1832, when in that year it was dis¬ 
covered by the late Mr. J. C. Dale at Lulworth Cove, 
Dorsetshire. Since that date it has been found in other spots 
along the southern coast. 
The Lulworth Skipper is an extremely active little insect 
and is one of the swiftest of the Skippers on the wing, darting 
about from flower to flower with remarkable rapidity. It is 
specially attracted to certain kinds of flowers such as Mar¬ 
joram, Rest Harrow and Thistles. During dull weather it 
rests with its wings tightly closed over its back, but while 
resting in the sunshine the hind wings are lowered in the 
same way as those of A. sylvestris and allied species.
