The terrestrial Adephaga of Iowa (Part 1) by Fanny Chastina Thompson Wickham, 1895

The terrestrial Adephaga of Iowa by Fanny Chastina Thompson Wickham, 1895, Page 3

Coleoptera are readily distinguished from all other orders of insects by the thickened horny anterior wings which are not actively used in flight, the free thorax, the presence of never more that two ocelli and the masticatory mouth parts. The metamorphosis is always complete; the larva is mandibulate, and the pupa inactive.
In order to make more clear the exact meanings of the terms used in the following pages I have thought best to give as briefly as possible a description of the external anatomy of a beetle; following this by the general classification of Coleoptera so as to show more clearly the relation of terrestrial Adephagons Coleoptera to all other beetles; then the body of the work. As far as possible the original description of each species has been given followed by one pf my own where necessary. The life history has also been given when known. The localities in Iowa are from lists made by J. D. Putnam, Herbert Osborn, Mr. Wickham and Leng and Beutenmüller. The authorities for all being given in the body of the work.
