I ate something similar a lot while I was in India. I think they're from the British influence. British biscuits are very yummy and not to sweet, which is good for me, because if something is very, very sweet, then I want to eat more and more!
My favorites are "digestive" biscuits, which are higher in fiber than most cookies, and are very yummy. McVities was the brand I would always get- there were about $2 a package over there, so I assume they can't be that much more here?
