A LIST OF THE COLEOPTERA OF IOWA By H. F. WICKHAM. This catalogue has been prepared as a necessary-preliminary to a projected siirvej' of the beetles of the state. As matters now stand, no one can identify even a reasonable proportion of his captures in this order without the expenditure of a sum of money altogether disproportionate to the results attained. The writer hopes to render conditions somewhat easier by the prepa-ration of a series of memoirs upon Iowa beetles with the idea of assisting students of our local fauna to name their specimens properly. Unfortunately our knowledge of certain groups is insufficient for complete treatment, since collections from the northern and western parts of the state are but few. However, a beginning has to be made somewhere and it is hoped that this list win serve to show what parts need attention as well as to indicate what is already known. Several lists of our beetles have been printed in local publica-tions and numerous records exist in the current literature of North American entomology'. The first serious attempt in this direction was made by J. Duncan Putnam^ in three papei"s on the Coleoptera of Davenport, Monticello and Frederic, but the number of species is not large. This was followed by a "List of the Coleoptera of Iowa City and Vicinity'' by the present writer-in which 871 names were given. Soon after appeared a "Partial Catalogue of the Animals of Iowa'' by Herbert Os-born.^ comprising the species of the preceding lists reinforced by several himdred records from Ames and a few from other points. To this the present writer* printed additions numbering iProc. Davenport Acad. Sci., Vol. I., 1876, 169-173. 2 Bulletin Lab. Nat. Hist.. State Univ. of Iowa. Yol.
