Butterfly: Sand-dune Widow

Here's another butterfly that I need ID help with. Seen in my garden in Darling in October 2011.

I believe that might be Tarsocera cassina; common name: sand-dune widow; and a member of the Satyrinae. Migdoll's field guide says it "has an unusual haunt in the sandy coastal strandveld of the south-western Cape lowlands….It is on the wing from October to early December….Recorded localities…extend from Malmesbury and Darling south-eastwards to the Bredasdorp district."

It seems it's found in just a few months, and in a relatively small area, so well spotted, arks.

I found that I took some far better pix of the sand-dune widow a few days later, so here are a couple :) Again, seen in my garden in Darling.
