extent of the orange spots is very variable ; sometimes they are 
very small and separate, and in other specimens they form a 
rather broad snbmarginal band. The male has some black scales 
near the base of the fore wings beneath the median nervure ; 
these are absent in the female, which is larger and paler than the 
other sex. Under side : Fore wings light brown, speckled with 
grey at the apex ; there is always one black spot present near the 
apex, and sometimes one or two more below this ; hind wings 
smoky brown, mottled with light grey, the hind-marginal half 
lighter than the basal portion ; there is an angular dark central 
band and a black spot near the anal angle, which is sometimes 
ocellated. Marginal fringes greyish white and black. Nervures 
not differing from the ground colour of the wings. PI. LXIV., 4.

Expands from 1*60 to 2-0 in. Wings brown, the male with

have only one near the apex, sometimes one, two, or three more

and a much smaller one sometimes appears above it ; there are 
also occasionally two or three minute white spots. Hind margins 
darkish brown, with the fringes very distinctly brown and white.
