Leptura, Linneus, 



The genus Leptura, according to the species 

 described in the Systema of Linneus, is a well- 

 defined family. It is true that some species of 

 Donacia and Callidium will be found united with 

 them ; it is nevertheless one of the best charac- 

 terized of all the genera established by the above 

 author, and by later writers. Pachyta, and other 

 various forms, are still considered as justly belonging 

 to the family. It seems almost peculiar to North- 

 ern Europe and America ; some species, however, 

 will be found extending far into South America, 

 and one or two denominated as belonging to Tox- 

 otus, will appear in catalogues as inhabiting Ma- 

 dagascar. They deviate certainly from the typical 

 genera. The metropolis of Leptura may justly be 

 considered Northern Europe or Northern America. 

 Many of our English specimens have their exact 

 representatives in the United States, and by various 

 Entomologists, some species are considered iden- 

 tically the same. Some appear to be found in both 

 hemispheres. 



Linnean Species. 



Sp. 6. Revestita* — This insect is certainly the 

 Lep. villica of Fabricius. It is remarkable that the 

 Baron De Jean, and other French writers, quote 

 Fabricius repeatedly, while they neglect the Sys- 

 tema of Linneus. Schonherr also, in his Synonymia 

 Insectorum, makes the name of Revestita secondary
