The alimentary canal of stored grain beetles is relatively simple compared to those of the higher orders of insects. But there are certain specializations from the generalized alimentary canal of the insect described by Snodgrass (1935). Striking similarities of structure have been observed in course of morphological investigation of the alimentary canals of two distantly related groups of beetles living on stored cereals. The differences between the two groups are few.
