lowish, the yellow on femora of anterior trochauters and the yel- 
divided by a strong black line. low lines on all the tibize. While 
there is no reason to doubt that 
the legs are much blacker always 
than in the typical forms, there is 
here and there just the faintest 
trace of yellow on the femora, the 
relics of a certain amount of that 
colour which has become gradually 
obliterated through age (see on 
this point the slight discrepancy 
in Mr. Lucas’s two descriptions). 
Abdomen beneath marked longitudi- Very broad black markings occupy 
nally with black. the greater part of each side of the 
ventral suture, the red being re- 
duced to mere streaks. Rounded 
spots near genitalia small. 
Black lateral longitudinal mark- 
ings much more strongly developed 
than in the typical forms. 
Hind wings 27-30 mm. Hind wings 25°5-27 mm. 
Two males (coll. W. Evans), Glen Aros, Mull (August 6th), 
and Morvern, Argyllshire (July), agree very well with the Mallaig 
examples, that from Mull being especially dark. A female from 
Moidart, Inverness-shire, in September (coll. Evans), has the 
thoracic spots rather larger, and the femora distinctly lined 
with yellow. 
A fine male from Talladale, Loch Maree, Ross-shire (August 
11th), which has the sides of thorax very darkly marked, has 
distinct narrow yellow lines on the femora, while a female also 
from the Loch Maree district is very similar to the Moidart 
female (male and female, coll. J. J. F. X. King). Two very 
small specimens (male and female, the latter teneral, hind wing, 
male, 24 mm.) are also in King’s collection, without label, but
