It is roundish, with swellings at intervals, from four to seven inches long,white, with tints of green andviolet. This worm infests allthe hog kind. It is found inthe small intestine. This par-asite requires an alternatehost, which is supposed to bethe larva of the May Beetles,Lachnosterna, and other rela-ted insects.
