have been enumerated and described by Prof. Bronn,* Prof. G-ermar,t 

 Dr. Giebel,:]: Prof. Heer,§ Dr. Hagen,|| Herr Carl von Heyden,^ 

 and Herr Lucas von Heyden.** These 242 species are distributed 

 amongst the existing Orders as follows: — Coleoptera (126), Neuroptera 

 (16), Orthoptera (3), Hemiptera (10), Diptera (76), Hymenoptera (8), 

 and Lepidoptera (3). The majority of the Coleoptera belong to existing 

 genera of the Families, Garahidcs, Hydrophilida, DytiscidiB, Hydrohiidcs, 

 Stnp'hylinid(je,Buprestid(e,Sca7'a'bcBid(S,SilpMd(S,Trogositid<B,TenebrionidcB,

 thidcd, Cassididce, Elateridce, Dermestidce, Telephoridce, Oantharidce, Gur- 

 culionidce, Ghrysomelidce, and Goc cine] I i dee. -ff The Neuroptera belong 

 to the Families, Lihellulidce, Termitida, Sialidcs, and MyrmeleontidcB ; 

 and the Orthoptera to Locustidcd and Blattidce. The Hemiptera are 

 represented by Nepidce, Notonectidae, Lygceidce, and lassidce. Nearly 

 half the species of Diptera belong to the Bihionidce ; the remainder 

 are distributed amongst the Syrpliida, Culicidce, Cecidomyiidce, Ghirono- 

 midcB, MuscidcB, Empidce, Tip id idee, As Hides, StratyomyiidcB, and Myceto- 

 philidcB. The Hymenoptera are represented by Apidce and Formicidce; 



yand t\iQ Lepidoptera mcYu^e one species of Ti7ieidee {Nepticulafossilis), 

 and one butterfly, Vanessa vetula, which is the only specimen yet ob- 

 tained from the horizon of the Lower Miocene of Europe. 



From the freshwater strata of Auvergne, in Central France, fossil 

 insects have been obtained in several localities, and about 4S species 

 have been described by M. Oustalet,JJ and one species by M. Charles 



: Brongniart.§§ Of these 49 species, 31 belong to the Diptera (chiefly 

 Bihionidce), and 10 to the Goleoptera (Dytiscidce, ITydrophilidts, and 

 GiircuJionidce). The Neuroptera are represented by Libellulides, 

 Myrmeleontidce, and Phryganeidce ; and the Orthoptera by one species 

 (undetermined). Of the two remaining insects one belongs to the 

 Hymenoptera, and the other {Noctuites incertissima) to the Lepidoptera.
