The midgut of C. (G.) truncata accounts for half of the postgastric intestinal tract. The paired anterior midgut caeca arise just behind the pyloric stomach, on either side of the midgut. The unpaired posterior midgut caecum arises dorsally at the rear end of the midgut, where this joins the hindgut. The midgut and its caeca help in the digestive absorption of food. The hindgut is of ectodermal origin and is lined with chitin of a collagenous nature. The connective tissue of the anterior part of the hindgut is packed with tegumental glands whose secretion contains both sulphated and weakly acidic mucosubstances, which facilitate the passage of faecal matter and help to bind food particles. The digestive gland - the hepatopancreas - opens into the anterior part of the midgut, below the anterior midgut caeca. Histologically, its tubules contain three different types of cells - "F", "R" and "B" cells.
截形库蠓（C. (G.) truncata）的中肠占胃后肠道的一半。成对的前中肠盲囊在幽门胃后方、中肠两侧处发出。不成对的后中肠盲囊在中肠后端的背侧发出，此处中肠与后肠相连。中肠及其盲囊有助于食物的消化吸收。后肠起源于外胚层，内衬具有胶原性质的几丁质。后肠前部的结缔组织充满了皮腺，其分泌物含有硫酸化和弱酸性的黏液物质，这些物质有助于粪便的排出并帮助黏附食物颗粒。消化腺——肝胰腺——开口于中肠前部、前中肠盲囊下方。从组织学上看，其小管包含三种不同类型的细胞——“F”细胞、“R”细胞和“B”细胞。
