It looks like it's knitted diagonally. Looks like a herringbone stitch of some form. You might try googling "diagonal herringbone knit stitch pattern". I have a herringbone pattern stitch at home in one of my books, just not like this one...will check for you later in the day. Mary

It looks more like a 'woven' fabric to me instead of being knitted. However, it is in the houndstooth pattern as others have mentioned.
