Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, B.C. Volnme 111 I960 Number 3425 NOTES ON LARVAE OF NINE GENERA OF APHODIINAE IN THE UNITED STATES (COLEOPTERA : SCARABAEIDAE) By Manohar Lal Jerath^ The coprophagus scarabaeid subfamily Aphodiinae contains a great many species of small to medium-sized beetles with a great diversity of habits. Most species are found in dung; some, however, are found in soil or sand feeding on organic matter or roots of living plants; others are said to be parasitic. The subfamily is worldwide in distribution. This study of the systematics of larval Aphodiinae, begun in November 1954, was undertaken because practically nothing was known of the American genera and species. It was suggested by Dr. Paul O. Ritcher, Department of Entomology, Oregon State College, Corvallis, Oreg., and is based on the study of larvae and adults loaned from the U.S. National Museum (USNM), Dr. Ritcher's personal collection (POR) and material collected by the writer. The assistance and encouragement of Mr. O. L. Cartwright of the U.S. National Museum are gratefully acknowledged. ' Hoshiarpur, Punjab, India. 43
