This list of the types of Coleoptera in the Australian Museum has been compiled with the purpose of assisting workers in the Order, as many enquiries are received both from Australian and overseas students regarding the location of certain types.
With the ever-increasing number of described species and the consequent necessity for access to the types, a knowledge of their present location is imperative. The position is rendered difficult by the transfer of material from private collections to institutions such as this, as in the original descriptions the types are stated to be in the author's collection. Certain collections have been acquired by the Australian Museum, and the types are now housed in its collection, e.g., the A. H. Elston Collection, and types from the H. J. Carter Collection.
Especial difficulty is experienced in tracing the Macleay types, since these are to be found both in the Australian Museum and in the Macleay Museum, University of Sydney. The types contained in the Australian Museum might, perhaps, be described as type-series, but where they are stated to be Holotype and Paratype in the present list, the specimen bearing the original name label has been selected as the Holotype. Types in the Macleay Museum Collection are not specially indicated as such, and their determination is necessarily a matter of difficulty.
