Bourlet's Memoirs on the Podurid^ and Smyntliuridse 

 in tlie 'Ann. de la Soc. Ent.de France' for 1841 and 1842, 

 contain merely sliort abstracts from his other works. 



In 1842 Mr. Westwood described and figured^ the 

 very interesting genus Campodea, which he correctly 

 described as " more nearly allied to Lepisma and Ma- 

 chilis than it is to any other group of annulose animals."" 

 It was also discovered independently by Gervais." 



M. Lucas, in the ' Annales de la Societe Entomo- 

 logique de France ' for 1843, pubhshed an account of 

 the memoirs on the Poduridce which had appeared 

 since the time of Latreille, and gives a list of all the 

 known species.^ 



The ' Histoire Naturelle des Insectes Apteres,' by 

 MM. Walkenaer and Gervais,* appeared shortly after- 

 wards.
