Aedes twniorhynchus is reported by Theobald, on the authority of Miss Lud- 

 low, from localities in Arizona and Illinois; as the species breeds only within 

 tide-water, and the flight of the adult does not range beyond 40 miles at the 

 most, these records are clearly based on misidentifications. We are also inclined 

 to doubt the records from the same authorities of its occurrence at Fort Wright, 

 Washington, and Fort Morgan, Alaska. The species is also reported from 

 Florida, but the many specimens we have examined from various localities in 

 Florida have proved to be the closely related Antillean form A edes niger.
