 The Diptera, which are very numei'ous, are distributed amongst the

 Myrmicidce, and Chalcididce : and the Lepidoptera by one species* be- 

 longing to the Nymplialidce — Prodryas Persephone — the only fossil 

 butterfly yet discovered in the New World, and which is remarkable, 

 not only as being in more perfect condition than any of those obtained 

 from the Eui'opean Tertiaries, but, " in presentiug,t as none of the 

 " others do to any conspicuous degree, a marked divergence from 

 " living types, combined with some characters of an inferior 

 " organization." 



Arctic Pegions. 



From a number of fragments of fossil insects obtained from the 

 Miocene formation of Spitzbergen, in the Arctic Ocean, Dr. HeerJ has 

 determined 23 species, 20 of which belong to the Goleoptera, and are 

 distributed amongst the Families CarahidcB, Dytiscidts, Silpliidce, 

 HydrohiidcB, Elaferidcd, Chrysomelidee, and CurcuJionidce. Of the 3 

 remaining insects, one belongs to the Ortlioptera {Platta liyperhorea), 

 and 2 to the ILymenoptera {Tlymenopterites deperditus and Myrmicium 

 bore ale). 



Dr. IIeer§ has also described 7 species of insects from the Miocene 

 formation of Greenland. Of these 7 species, four belong to the 

 Coleoptera (^Trogositidce, Cistelidce, and ClirysomelidcB), one to the 

 Orthoptera (Blattidium fragile) , and two to the Semiptera {Gercopidium 

 rugulosum and Pentatoma horeale). 



Representatives of almost all classes of the Animal Kingdom have 

 been discovered in the rocks of this Period, but as the majority belong 

 to existing types, a very brief notice of them will be sufficient.
