BLATTDm 13 



Suborder ORTHOPTERA GENUINA*. 

 Fam. BLATTIDiE f . 



For the classification of this family we have followed in a general way the excellent 

 work of Herr Brunner von Wattenwyl, ' Nouveau Systeme des Blattaires,' and his 

 'Revision du Systeme des Orthopteres, 5 in which he has introduced some modifications 

 of his former system. Nevertheless, we have been obliged to give here a Conspectus 

 of the tribes and genera, as it was necessary to introduce several modifications in the 

 method of the author, particularly in regard to the American Blattidae and to the 

 disposition of the new genera. 



Many species are very vagrant, finding their way into habitations, storehouses, 

 merchandise, and ships, and are thus readily transported from one country to another. 

 Some are quite cosmopolitan, and this has induced us to enumerate a number of 

 species inhabiting the Antilles and South America which may possibly be found in 

 Central America ; others we have mentioned to avoid confusion with allied species of 

 the central parts of America ; the names of these are placed within square brackets.
