Eocene insects from Denmark

The insect material from the Eocene deposits of Denmark which I have had for examination, and which will be treated on the following pages , comprises - to the best of my knowledge - all insect finds procured from the Eocene deposits of Denmark. All the finds originate from the lower Eocene Diatom-earth bed occupying a limited territory round the western part of Limfjorden in northern Jutland. With a single exception (Rhamphidia sp . which has been found in » Moler « (Diatom-earth proper) the rock from which all the finds have been produced is the hard, chalky »Cementsten « (cement-stone) 1 ) in which the impressions keep better than in the soft, loose Diatom-earth. Only few insects have been previously mentioned in the literature as originating from the Eocene deposits of Denmark, and then only in a few phrases or remarks.
