Abstract

On July 21, 1955 a woman forty-three years old in London, Ontario experienced a sensation of peri-anal itching, and suspecting the presence of pin-worms, examined a stool following a bowel movement. In it was found a small, dead "worm". When examined by the writer this proved to be a larva, 7 mm. long, of a beetle of the genus Attagenus as identified with keys in B. E. Rees (1943. Classification of the Dermestidae (larder, hide, and carpet beetles) based on larval characters, with a key to the North American genera. U.S. Dept. Agric., Miscell. Publ. No. 511). It closely resembled the larva of Attagenus piceus figured by A. Gibson and C. R. Twinn (1939. Household insects and their control. Dept. Agric., Canada, Publ. No. 642). A. piceus is a beetle of cosmopolitan distribution and its larva feeds on furs, skins, woolen fabrics, stored grains and cereals (Busvine, J. R. 1951. Insects and Hygiene. Methuen and Co., London).
