Possible Phyciodes orseis herlani, California Crescent

This individual (both photos are of the same one) looks rather like pictures of Phyciodes orseis herlani to my eye, but also don't seem to be out of the range of of variation for the montane form of Field Crescent, Phyciodes pulchellus. Some field guides suggest orange-tipped antennal clubs eliminate Field Crescent, but I'm not convinced of this.
