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
