The hindgut in Ips typographus (Linnaeus 1758) consists of an anterior part (ileum), and a posterior part (rectum). It is built up by the following elements: an inner cuticular lining, an epithelial layer, and an outer layer of muscles. The rectum is surrounded by the Malpighian tubules and a perinephridial membrane forming a cryptonephric system below a rectal pad. The structure of the cuticula and epithelial layer is variable in different parts of the hindgut. There are no specialized glandular cells connected to the hindgut, but there is evidence of secretory activity in the epithelial cells.
