Anterior wings brown-black, with darker black clouds, the hinder margin varied

 two pair of short white lines : cilia ashy at the base, black at the apex : pos- 

 terior wings black, with brown cilia ; the base with a black Une. 



Apparently very rare : I have once taken it at Coombe Avood, and

Anterior wings obtuse, black, with darker clouds, with an ill-defined, irregular 

 large ochraceous-wliite blotch in the middle of the inner margin ; cilia black :

 elms.

Rather scarce ; found at Coombe wood in June, and in Norfolk
