and from this rock comes the almost complete specimen of 
Blapsium Eyertoni. Libdkda may also be noticed from the 
Purbeck Beds and from the Bagshot Beds of Upper Eocene 
age near Bournemouth. Tliese last-mentioned beds, as well 
as the Oligocene Bembridge Beds of Gurnet Bay in the 
Isle of Wight, have furnished a number of insects belonging 
to many modern families. 
Among the fossil insects from foreign localities we 
notice first some Orthoptera allied to the cockroaches, and 
some large Neuroptera, from the Coal Measures of Com- 
mentry, Allier, France ; a locality famous for the beautiful 
examples that it has yielded. The next series of importance 
is that from the Lithogi’aphic Stone of Solenhofen ; here

we may imagine that numerous insects lived on the islands 
around a lagoon, into whose placid waters they were 
constantly being blown. The Orthoptera are represented 
by the cricket Pseudogryllacris [Grullacris], by the locust 
Pi/cnophlcbia, and by Chresmoda \Pygolanipi^'\ obscura, a 
precursor of the Mantidae and Phasmatidae or stick-insects. 
Among the Neuroptera is the dragon-fiy Cgmatophlebia. 
Water-bugs allied to Neim and Bdostovia represent the 
Hemiptera. Beetles are numerous. The chief example of 
the Hyinenoptera is Pseudosire^v, one of the tailed wasps 
that bore into trees. Cretaceous insects are unrepresented, 
but there are many from Tertiary rocks, all of modern 
type. The Oligocene deposits of Aix in ITovence, the 
Miocene Beds of Florissant in Colorado and of Oeningen on
