enumerated about 114 species, distributed amongst all tbe existing 

 Orders, as follows : — Coleojitera, 29 species ; Neuroptera, 46 species ; 

 Ortlioptera, 11 species ; Hemijjtera, 16 species ; Diptera, 5 species ; 

 Symenoptera, 5 species ; and Lepidoptera, 2 species. 



Tbe majority of the Coleoptera belong to existing genera, distri- 

 buted amongst the following families, yIz. : Scarahcdidce, Carahidce, 

 Hydropliilidce, Gyrinidce, S/lpJitdce, 8caphidiid(S, Trogositidce, Ilisferidw, 

 Meloidce, Buprestidce, ElateridcF, TcnehrionidcB, Curculionidce, Chryso- 

 melidce, Cassididcs, and Coccinellidce ; there are also several species 

 belonging to extinct genera. 



The Neuroptera are represented by Terinifidcs (Termes) ; Ephe- 

 meridce {Ephemera), HemerohiidcB {Hemerohius, Clirysopa, ApocJirysa, 

 and Nymplies) , Sialidce (CorydaUs), Myrmeleontidce {Myrmeleon), and 

 Libellulidce. Tbe great majority of tbe fossil Neuroptera* from 

 Solenbofen belong to tbe family last named {Lihellulidce) , wbicb is 

 represented by about 10 genera, including tbe following : Isop)hJehia, 

 StenophJehia, Heteropihlehia, EuphcBa, Agrion, Anax, PetaJia, Petalura, 

 and Lihellula. Many of tbe species belonging to tbe genera Hetero- 

 phlehia, Petalia, and Petalura, are of gigantic size ; two of tbem 

 having an expanse of wings of 7i — 8 inches, with bodies of 3| — 4 

 inches in length. 



The Ortlioptera include the following, viz. : Forjtcididce, {Eorficu- 

 laria), GryUidce (Gryllites and Acheta), LocustidxE {Locusta and 

 PJianeroptera), and Blattidce {Blattaria). 



The Heviiptera are represented by Notonectidce (Corixa), Ncjjidce 

 {Nepa, Nmcoris, and BeJostoma), Cicadidce (Cicada), Flat idee 

 (Bicania), Gerridce (Velia), By strides {Lystra), and Beduviidce 

 {Byyolampis and Fropygolaonpis) . 



The five species of Diptera are respectively referred to five 

 families, viz. : AsiUdce {Asilicus), Muscidce (Mitsca), Tipulidce {Tipu- 

 laria), Fmpid(B {Fmpidia'), and SyrpJiidcc (CJiilosia). 



The Hymenoptera include three species referred to the genus 

 Apiaria, of the family Apidce, and one species doubtfully referred to 

 the genus Bomhus, of the same family. 



The Bepidoptera are rejiresentcd by two species — Spliinx Snelleni 

 and Pseiidosirex Baricini — the former of which has been decribed and 

 figured by Herr Weyenbergh in the " Archives du Musee Teyler."t 

 Assuming the figure to be accurate the insect must be in a very fair 



* Dr. Hagen states that, out of 450 specimens of fos.sil insects in the Munich Collection, 160 

 belong to the Ifturoptera, and that 136 of these are Libeliulidm. See the " Entomologist's Auuual," 

 1862,, p. 5.
