AUSTRALIAN DUNG BEETLES of the SUB-FAMILY COPRIDES By ARTHUR M. LEA, F.E.S., ENTOMoLocasr, S.A. Museum Plates vi-ix. In comparison with otlicr parts of the world Australia has but few Coprides, mostly below the aA'erag'e size of those occurring elsewhere; the largest species, Aiilacopris reichei, seldom reaching a body-length of an inch and a quarter. This, however, is only to be expected considering the dearth of large indigenous mammals. Dung beetles of several kinds have multiplied with the distribution of the cow and horse, and many European species have been introduced, especially in the Aphodiides and Staphylinidae. Some of our genera are of exceptional interest, such as Macropocopris, species of which live in the fur about the anal region of marsupials, and have developed extremely powerful claws; one species, M. sy))ihioticus, has been found in the cloaca of a Avallaliy. Dr. J. F. Tllingworth informed me that Pedaria goniiuifa habitually uses, for its own young, dung-balls formed by other species of Coprides.
