Middle Eocene. 



In the geological proceedings for 1854, Professor Westwood 

 describes and figures certain Buprestldce from the Leaf Beds at 

 •Creech, near Corfe, Dorset, belonging to the Bagshot series of the 

 Middle Eocene ; also Elytra of Helopida and Curculionidce from 

 the same formation. 



Mr. J. S. Gardner, F.G.S., has lately discovered remains 



of insects at Bournemouth, in the Leaf Beds of the Bagshot 



Sands ; they consist of Ebjtm of Cokoptera, wings of gnats and 



bees, Diptera, i.e., small and often fragmentary, and some others 



unknown. 



LoM'ER Eocene. 



In the list at the end of Mr. Brodie's last-mentioned paper, 

 " Elytra of Coleopfera " are recorded from the Lower Eocene of the 

 Isle of Wight, but are not named. 



Dr. Mantell, in his Geology of the Isle of Wight, mentions 

 that ]\Ir. Webster has observed traces of Coleopterous " Insects in 

 the London Clay, near Parkhurst," Isle of Wight. 

 Foreign Strata. 



On the Continent of Europe, discoveries of insect remains in 

 the Tertiary Strata have been made chiefly at (Eniugen in 

 Switzerland, Eadoboj in Gratia, Corent and ]\Ienat in Auvergne, 

 Siebengeberge on the Rhine, Aix in Provence, and at Monte 

 Bolca in Upper Italy. The remains of many species have also 

 been detected in Amber from various localities, but especially 

 from the Amber which the Baltic Sea throws up on the Coast of 

 Prussia. It is difficult to know to what geological epoch Amber 

 should be referred. By many geologists it is considered 

 antediluvian. Sir Henry de la Beche was of opinion that the 

 Prussian deposits] of Lignite and Amber belong to the Tertiary 

 rocks, and that its place was probably above the supracretacious 

 group. 



I wiU now proceed to notice, in descending order, the before- 

 named Continental localities and the principal species which 

 have been obtained from them.
