Intestinal Coleoptera

of children by these very peculiar beetles. Whether they enter by the mouth as an egg and undergo development into larva and pupa and finally into the adult beetle within the intestines, or whether they enter per rectum while children defecate in the open is not certain. Senior-White was the first to note that Onthophagus bifasciatus. Fb. (Copridae) infested the intestines. I have since observed that some other species allied to the above may cause similar trouble. When we find out what species of beetles infest human intestines in this way, a study of their habits would throw light 011 the mechanism of invasion of these beetles. The proper identification of the beetles is therefore important.
