A COMPARISON OF THE FOSSIL INSECTS OF 

 ENGLAND AND BAVARIA. 



By Dr. Hagen. 



{Read before the Geological Section of the British Association at Manchester, 

 September, 1861.) 



I AM desirous of making a few remarks on the Fossil Insects 

 of the Lias and Wealden, as far as they have been described 

 and figured. Formerly the fossiliferous strata of Solenhofen 

 and Eichstadt in Bavaria were considered analogous to the 

 English secondary strata; later investigations have, however, 

 established that the English strata, are considerably older. 

 The sjDecimens that have hitherto been described and figured 

 from the Bavarian strata are not sufficiently numerous to 

 enable us to form a judgment on the Fauna of those strata. 

 I must especially call attention to the fact that the species 

 described by Germar in the Acta Academise Leopold., to 

 which hitherto reference has always been made, are described 

 from specimens, the outline of which has been artistically 

 painted and completed. I have often examined the types 

 carefully and can certainly maintain that this account of them 

 is correct. 



The Royal Collection in the Academy of Munich and the 

 collection of Dr. Crantz of Bonn contain together about one 

 thousand stones with insects, and, even deducting the double 

 stones, this represents at least six hundred specimens. 



A few weeks back I had an opportunity of studying very 

 carefully the collection at Munich, and was much surprised 



1862. B
