the opposite direction, so as to point towards the anal angle ; 

 cilia pale fuscous. Hind wings broad with the apex bluntly- 

 pointed, rounded behind ; pale grey tinged with yellowish 

 at the base and along the dorsal region, shading into dark 

 fuscous at the apex ; cilia yellowish grey. Female similar, 

 with fore wings rather longer, broader, and more pointed. 

 Underside of the fore wings dark fuscous ; nervures promi- 

 nent ; of hind wings yellowish fuscous ; body and legs grey. 

 Slightly variable in the number and distinctness of the black

On the wing in the latter part of July and through August. 



Larva f inch long ; rather stout, cylindrical, tapering very 

 little at either end ; the usual tubercular spots, on each

August to May on lichens, and probably mosses, in the 

 wettest fens. In confinement it has fed upon Lichen caninus,

Pupa short, stout, very blunt behind, shining dark chest- 

 nut brown ; in a thin, webby cocoon of greyish silk, outside 

 which is a finer and thinner cocoon of white silk ; in a 

 curled-up bramble leaf. (Buckler.)
