EEVISION OF NEAKCTIC TERMITES. 153 



ill an infested building at Seabreeze, Florida, as late as April 7, 1919. 

 This was probably not the first swarm from this colony. A swarm 

 occurred outdoors at Texarkana, Arkansas, at 9.30 a. m. on April 8, 

 1919. Winged adults were collected flying near Mammoth Cave, 

 Kentucky, on May 2, 1874 (F. H. Sanborn); Newark, Delaware, May 

 19, 1892; on May 16, 1914, this species swarmed at Kanawha Station, 

 West Virginia, from an infested building; in 1915 the insects emerged 

 on May 8 (Hopkins). At Kanawha Station, West Virginia, on May 

 5, 1919, there was a swarm from a sill of the house, south end; the 

 dogwood flowers were with first pollen falling. The swarm started 

 about 10 a. m. with the temperature at 71° and continued until noon 

 when it had ended. On the 6th there was another swarm at about 

 the same time. 



In the Northern States Jlavipes swarms later, usually during the last 

 of May or early Jmie. Hagen (1878) mentions an exceptionally large 

 swarm of Jlavipes occurrmg in Massachusetts on May 19, 1878. 

 Hagen states that this is an early appearance for the insects; they 

 commonly arrive in the middle of June. Winged adults were collected 

 at Wellesley June 1, 1892, and Jmie 4, 1900, at Dover, and June 8, 

 1917, at Forest Hills, Massachusetts. However, winged adults were 

 collected at Sherbom, Massachusetts, May 21, 1899, and in May, 1906, 

 by J. Barlow at Kingston, Rhode Island. Sexual adults came up 

 through cracks in the floor in a building on March 30, 1908, at Phila- 

 delphia, Pennsylvania. On May 25, 1913, the writer found winged 

 adults with mature pigmentation in a colony at Charter Oak, Pennsyl- 

 vania. A. B. Champlain found winged adults in colonies at West- 

 bury, Long Island, New York, on May 28, 1916. On May 16, 1916, 

 this species swarmed m an infested building at St. Louis, Missouri. 

 In 1918 Jlavipes swarmed on March 6, in an infested building at 

 Rural Valley, Pennsylvania. On May 12, 1918, C. T. Greene col- 

 lected winged adults of R. Jlavipes at Lyme, Connecticut, in a colony 

 under a stone; they had nearly acquired mature pigmentation. On 

 January 20, 1919, there was a swarm in an infested building at 

 Bloomfield, New Jersey. On March 6, 1919, there was a swarm in 

 an infested building at Williamsport, Pennsylvania. The swarm 

 occurred when the sun was high. 



The sexual adults usually emerge approximately one month earlier 

 in infested buildings than under normal outdoor conditions. 



Li infested buildings at Brooklyn, New York, adults swarmed on 

 March 30 and May 29, 1917. Winged adults in the United States 

 National Museum bear the label' 'Albany, N. Y., March 29, '99, W. G. 

 Lewis." 



Winged adults have also been found in the faU of the year: Bergen 

 Beach, New York, Sept. 14, 1908; at Meldrim, Georgia, Nov. 3, 1915
