A Reticulitermes Flying at Night in Arizona. 



On July 5, 1919, Mr. Hofer also collected several species of 

 termites that were attracted to light in Sabino Canyon. Among 

 the species of Kalotermes and Amitermes, which are normally 

 nocturnal fliers, were seven specimens of a small, pale yellowish 

 brown species of Reticulitermes which apparently is new. This 

 is the first instance known to the writer of any species in the 

 genus Reticulitermes flying at night. Ten species occur in the 

 United States; in the eastern States these termites "swarm" or 

 fly during the forenoon of a bright, sunny, warm day. 



This new species may be the winged adult of a manuscript 

 species described only from the soldier caste by Banks.
