Do you have many inputs to add up to the 0.1BTC you're trying to send?  I just setup a transaction of 0.1BTC to see what the txn fee would be, and I got about $4 fee with 9 inputs.  In case you're wondering: Mycelium set for Economic send which now is 54 satoshis/byte

Edit- I see your transaction is 73600 bytes, which would be about $200 with my wallet above so I'd say that's it.
