[Hysteria]

I have a for loop that creates an amount of square sprites with random proprieties:

for (var i:Number=0; i<numBasicDots; i++) {
var mySprite:Sprite = new Sprite();
mySprite.graphics.beginFill(colorArray[randRange(0,colorArray.length)], 1);
mySprite.graphics.lineStyle(randRange(1,5), colorArray[randRange(0,colorArray.length)], 1, true)
mySprite.graphics.drawRect(randRange(0,300), randRange(0,300), randRange(1,600), randRange(1,600));
mySprite.filters = filterArray[randRange(0,filterArray.length)];
addChild(mySprite);
}

anyone knows how I can delete all of these sprites at the same time?
