In the alimentary canal of the alder flea-beetle, Altica bimargimita Say, (Chrysomelidæ) as in insects generally, three primary divisions of the digestive tract are at once evident; the fore-intestine (stomodaeum), the mid-intestine (mesenteron or ventriculus), and the hind-intestine (proctodaeum). In this larva, the comparatively short alimentary canal, which is a nearly straight tube with few convolutions, is somewhat less than half again as long as the body. The writer has already published a figure showing the general structure (Woods 1916, Fig. 1).
