In many situations, constructing off of the input archive like this 
works fine (assuming Foo is serializable):

Foo::Foo( InputArchive& archive )
{
     archive >> boost::serialization::make_nvp( "FooClass", *this );
}

This way, you could have additional constructor parameters besides the 
archive if you needed to, and your class doesn't have to have a default 
constructor.
