first and larger than the last. @. wnidentaria (the Dark-barred Twin-spot Carpet) is a very variable insect, 
but can generally be distinguished at once by the very broad and dark band, bordered with light, which crosses 
the centre of the brown ground of the fore wings. @. ligustrata (the Large Twin-spot Carpet) is much like the 
preceding in the broad band, but the ground colour is more ochreous in the fore-wings and clearer in the 
hind wings, and the insect is considerably larger. C. olivata (the Beech-green Carpet) resembles the two 
last in the broad band, but the ground colour is green, the dark bands being bordered with cream colour 
or pale ochre, and there is a small patch of ochre in the centre of the dark band. C. propugnata (the 
Flame Carpet) is again very distinct, the ground being flesh colour, with the broad band deep olive with 
a patch of lighter tone in its centre, the hind wings being entirely of a pale reddish brown or flesh tone. 
C. munitata (the Red Carpet) is also very distinct, the ground colour being warm pale brown, with the broad 
and strong red-brown, approaching red. All these pretty species are tolerably common, and some very 
abundant ; C. olivate is found chiefly in birch woods ; C. salicata, a northern species, is the most rare.
