Potter Wasp

Same one was documented here: http://greenogreindia.org/balcony-bugwatch-the-moron-the-lightbulb-and-… however, I wasn't able to determinate the species, but it is probably a common wasp in India.
Probably Ichneumonidae, similar spotting was identify as that http://www.flickr.com/photos/25258702@N04/6828158018
