Having had to look it up myself, I kept playing thinking "there has to be an easier way.
So far the "best" is:

   sudo route del -net $IP netmask $MASK dev $IFACE

If you have more than one network interface $IFACE may need to be determined with something like:

  michael at hive:~/play$ netstat -nr
  Kernel IP routing table
  Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
  64.105.252.40   0.0.0.0         255.255.255.248 U         0 0          0 eth0
  192.168.14.0    64.105.252.41   255.255.255.0   UG        0 0          0 eth0
  169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0
  0.0.0.0         64.105.252.41   0.0.0.0         UG        0 0          0 eth0

And the relevant clue stick from `man route` is:

    SYNOPSIS

       route  [-v] [-A family] del [-net|-host] target [gw Gw] [netmask Nm] [metric N] [[dev] If]
