Fatal error: Class 'MY_Controller' not found in C:\xampp\htdocs\project\application\controllers\site.php on line 3

I have:

    function __construct()
    {
        parent::Controller();

    }

<?php

class Site extends MY_Controller {

    function __construct()
    {
        parent::MY_Controller();
    }

    function index()
    {
        echo 'working..';
    }
}
