towards extremities suffused with bright ochreous-orange, its upper margin 
rather deeply indented at 4, thence somewhat dilated, and again attenuated 
to apex : cilia reddish-ochreous brown, beneath anal angle ochreous-whitish 
suffused with orange. Hindwings dark grey ; cilia grey, extreme base pale. 
A very distinct and handsome species, in form of wing very closely 
approaching the preceding ; in colour it is approached by the much smaller 
and narrower-winged Cremnogenes oxyina, but the resemblance is analogous 
merely, and due in each case to protective imitation of the colouring of a 
- dead beech-leaf.
