REVISION OF NEAECTIC TERMITES. 165 



Winged pigmented adults of this termite were first found by the 

 writer on July 24, 1911, in the bases of telegraph poles at Kane 

 (Greene County), Illinois. 



R. Tiageni has been found from the vicinity of Washington, District 

 of Columbia, south to Florida (Osten Sacken). Winged adults are 

 in the Museum of Comparative Zoology at Cambridge, Massachusetts, 

 which were collected at Charleston, South Carolina. It is a southern 

 species, not being found farther north than southern Maryland, but 

 occurs as far west as Illinois and Texas. 



SWARMING. 



R. Jiageni is a species which swarms late in the season. As stated, 

 the writer found a few winged adults in a colony in the base of a 

 white cedar telegraph pole at Kane, Illinois, as late as July 24, 1911. 

 Apparently most of the colonizing adults had swarmed. On August 

 9, 1912, the writer found a few scattering adults flying at Washington, 

 District of Columbia. On August 11, 1913, Wm. Middleton collected 

 a large number of swarming winged adults and a few soldiers from a 

 colony in a small chestnut corner stake at Falls Church, Virginia. The 

 colony, which was not large, swarmed at 12.30 p. m. On August 17, 

 1913, the writer again collected winged adults at Chain Bridge, Virginia. 



At Richmond, Virginia, on August 11, 1916, E. W. Trafford found 

 winged adults in the base of a chestnut telegraph pole. On August 17, 

 1916, N. Banks collected a few flying adults at Great Falls, Virginia. 



On September 1, 1917, at the corner of Corby's and Bennings' 

 Roads, District of Columbia, A. F. McDermott collected an Asilid 

 fly feeding on winged sexual adults of this termite, which was swarm- 

 ing in large numbers. The fly is HolcocepJiala ahdominalis. 



Osten Sacken found adults in Florida in March, 1858; the label on 

 other winged adults is Jacksonville, Florida, April 29. 



H. S. Barber found adults flying on June 9, 1905, at Lake Drum- 

 mond, Dismal Swamp, Virginia. On October 30, 1918, Barber 

 found a pair of dealated adults in a cell under a log near Harrisburg, 

 Texas. They apparently represent a variety. 



This termite is similar in habits to others in the genus Reticulitermes. 

 It has been found destructive to telegraph poles, corner stakes, and 

 other wood in contact with the ground.

 Europe.
