These fossils have been referred to the Orders Neuroptera, 

 Ortliojptera, Coleoptera, and Hemiptera ; and one or two specimens 

 have been doubtfully referred to the Diptera. 



The Neuroptera* included the genera Ortlwphlehia, Hemerobms, 

 Ohmdiodes, Agrion, ^sch^ia, Lihelhda, Seterophlehin, and Epliemera ; 

 and the Ortlwptera were represented by GryJlus and Blatta. 



The Coleoptera — which was far more numerously represented than 

 any other Order — comprised specimens of the following Families, 

 viz. : ScarahceidcB (Melolonfha) , HydropTiilidce, Gyrinida, Buprestidce, 

 ElateridcB, LaonpyridcB, ClirysomelidcE, CurcidionidcB, Carahidcd, and 

 Telephoridcs. 



The few specimens of the Hemiptera which have been discovered 

 have been referred to the genera Clmex, Selostoma, and Cicada. 



No traces of Hymenoptera or Lepidoptera have been recorded, 

 and the remains which have been referred to the Dipt era are very 

 doubtful, t 



Although, as a rule, the insect remains from this formation are 

 very imperfect and fragmentary, the wings of some of the Neuroptera 

 are preserved in the greatest perfection. 



The majority of the species seem to have been of very small size, 

 and indicative, if considered apart from the other animal and vegetable 

 remains of the Period, of a temperate climate. 



Continental Europe. 



A few elytra of Coleoptera have recently been discovered in 

 HhseticJ beds, in the Province of Schonen, in kSweden. 



These remains have been referred by Professor Heer to seven 

 species, which he has described,§ and severally named — HydrophiUtes 

 Nathorsti, Suprestites rtiytdosus, Curculionites parvulus, Curculionites 

 Carlsoni, Wytridium Angelini, Elytridium Icevigatum, and Carabites 

 deplanatus. 



From the lower marls of the Lias at Schambelen, in the Swiss Alps, 

 some 2000 specimens of fossil insects have been obtained. These 

 fossils bave been carefully studied by Dr. Heer,|| who has referred 

 them to 142^ species which are distributed amongst the following 

 Orders, viz. : Neuroptera (7 species), Ortlwptera (7 species), Hemiptera' 

 (12 species), and Coleoptera (116 species).

t Of one of the supposed ZJip^cj-a from the Lias, Prof. Westwood observes, " seems like the 

 body of a Tipulideous insect ;" of another fr.agment, he says, "may possibly be Dipterous, allied 

 to Asilui." Brodie's " Fossil Insects," antea cit., p. 128.
