The insects included in these genera were said by Marcel de 

 Serres, to be all of European forms, and to be mostly referable 

 to species still existing. 



A number of insects from this locality (including some 45 

 species, collected by Murchison and Lyell) were also described by 

 Mr. Curtis, in 1829. They consisted principally of Bipteru, 

 Hemiptem, and Coleoptera, with a few Hijmenoptcra, and one 

 Lepidopkrous insect. According to Curtis, several of the beetles 

 had their wings extended beyond the elytra, as if they had 

 been tiying and had dropped, and a Chn/somela had the elytra 

 expanded, from which it would appear that it had fallen upon 

 the water and been drowned. Other insects appear to have been 

 imbedded whilst in repose or Avhen walking. 



Some eight years later, when Bronn published his " Lethcea 

 Geognostica," a great number of other genera had been discovered 

 in this locality, for in the second volume of the last named work 

 the foUoAving are enumerated : —

besides the four Lepidnptem mentioned by Marcel de Serres. 



By the year 1844, the researches and inve.stigations of the 

 Rev. F. W. Hope in this locality, had raised the number of genera 

 enumerated by Marcel de Serres, Curtis, and Bronn, to one 

 hundred and thirteen, for twenty of which we are indebted to 

 Mr. Hope. 



For some years after the date of Mr. Hope's paper the fossil 

 • insects of Provence, which had for a time attracted a considerable 

 amount of attention from geologists and Paleontologists, remained 

 unnoticed. At length, in 1851, Professor Hecr commenced to 

 study them. In addition to the specimens he himself obtained 

 durino' his travels in Provence, he was enabled to study those in 

 the collection of M. Blanchet, of Lausanne, and those collected 

 by Sir Roderick Murchison, in 1829.
