>From the iptables man page:

-D, --delete chain rule-specification
-D, --delete chain rulenum

    Delete one or more rules from the  selected  chain.
    There  are  two  versions of this command: the rule
    can be specified as a number in the chain (starting
    at 1 for the first rule) or a rule to match.

so in this case it'd be:

/sbin/iptables -D INPUT -s 65.19.175.58 -j ACCEPT
