Be this as it may, we must now abandon the view that the large 

 paper nests occasionally found in North Carolina and Florida are 

 merely so many sporadic or local adaptations of C. lineolata col- 

 onies to living in flooded districts, and must regard them as the 

 work of a peculiar species whose method of nidification is unlike 

 that of any other Nearctic ant though very similar to that of many 

 of the tropical species of Crematog aster.
