ginihus apicalihus fere verticalibus, sub-rhomboideis, cants, nigro- 
irroratis ; strigis basalihus conspicue nigris ; lineis primis costam 
versus obliquis ; secundis denticulatis, albido-margmatis ; margin- 
ibiis apicalibus punctatis ; ciliis saturatiore regulariter intersectis : 
posterior ibus candidis, sub-hyalinis, vix.fusco tinctis. 
Exp. alar, fceminis, 9i"'-10l"'; maris, 9"'-9f"'. 
Habitat : Surrey, Sussex, "Worcestershire. 
Fore-wings in both sexes broad, of rhomboidal shape, having

1. s. hasistrigam. 2. ,<:. ambiguaiu. streaks passiug from the 
base of the wing along the sub-costal and median nervui'es respectively, 
the edge to the space preceding the first line generally paler. First line, 
commencing obliquely from the costa, passes backwards and inwards to 
the orbicular stigma, thence forwards and inwards to meet the claviform 
stigma, which is incorporated with (not detached from, as in some of 
the genus) this line, and finally with an S-like bend, reaches the inner 
margin. Medial area; the orbicular and reniform stigmata are situated 
on patches of dark fuscous colour, the black outline of the latter (the 
reniform or 8 mark) forming an "B-like mark. Second line rather 
serrated, two of the serrations situated above the middle being promi- 
nently produced towards the hind margin. Apical area : in this space 
the edging of the second line is pale whitish-grey ; the upper and lower 
dark shades usually join ; hind margin of wing dotted ; the pale cilia 
cut up at regular intervals with square patches of dark-coloured scales. 
Hi/id-icings silky-white, with a very slight fuscous tint.
