III. — The Miocene Insect-fauna of CEningen, Baden. 



By Samuel H. Scudder, Cambridge, U.S.A. 



(PLATE VI.) 



THANKS solely to the labours of the late Oswald Heer, the fossil 

 insect-fauna of CEningen is better known than that of any 

 other locality or horizon in the world. But it is by no means so 

 well known as it should be ; for although Heer, in his latest 

 enumeration of the specimens seen by him (Urwelt der Schweiz, 

 2^ Aufl. 1879, p. 383), repeats preciselj' the same figures he has 

 already given in 1861 (Eecherches sur le climat du 'pays tert., p. 197), 

 indicating in an interval of eighteen years no addition to his 

 material (over 5000 specimens), his repeated additions to the 

 number of species from that locality show that he had not fully 

 worked over what he had. Indeed, thirty years ago, I arranged for 

 exhibition in the Museum of Comparative Zoology at Cambridge 

 a collection of nearly one hundred and fifty named species secured 

 by Prof. Louis Agassiz from Heer, of which more than forty still 

 remain undesoribed ; there are also a considerable number of merely 

 nominal species enumerated by Heer in his Urwelt der Schweiz and 

 elsewhere, duly catalogued by me in my Index to Fossil Insects 

 (Bull. U. S. Geol. Surv. No. 71), but as yet neither described nor 

 figured. In addition to this it may be noted that in the enumeration 

 referred to above Heer mentions 543 species of beetles, while less 

 than 270 nominal species have yet been published from CEningen, 

 and only seven species from the Swiss Miocene, included in the 

 enumeration.
