The alimentary canal can be divide into three parts including stomodaeum, mesenteron and proctodaeum. The stomodaeum is composed of mouth, phorynx, oesophgus, crop and proventriculus, while mesenteron is a simple straight pipe. The proctodaeum can also be divide into three, that is, ileum, colon and rectum. Moreover, there is a gastric caeca outside the joint of proctodeum and cardic valve inside the joint. Also at the joint of mesenteron and proctodeum, there has a Malpighian tubes outside and pyloric valve inside. On the wall of stomdeum there always exist teeth of various forms and shapes in different plasce. In the rectum, there are rectal pads. The salivary glands are in the shape of graph, composed of many secretory orbed bodies, some short small branches and two salivary pipes. The two pipes join into a general one.
