invoke a prefab as child

invoke a prefab as a child, I need all the objects are invoked inside an empty object.
please, this my code

using UnityEngine;
using System.Collections;

public class Invoker : MonoBehaviour {
	public GameObject Objeto;
	// Use this for initialization
	void Start () {
		for (int Q=0; Q<10; Q++) {
			Instantiate (Objeto, transform.position+=new Vector3(0,-0.35f,0), transform.rotation);

Hi matey!

I was actually doing this the other day, funnily enough. Off the top of my head, it went a little like this:

    void Somefunction(){
        GameObject object_o= Instantiate (Objecto, transform.position+=new Vector3 (0f, -0.35f,0f), transform.rotation) as GameObject;

I hope this helps!
