REVISION OF NEARCTIC TERMITES. 163 



On March 30, 1914, winged adults of this termite were found in an 

 infested building at St. Augustine, Florida. At Homestead, Florida, 

 the swarm occurred on March 6, 1917 (C. A. Mosier). Winged adults, 

 mature and ready to swarm, were found in a log at Brickell Hammock, 

 Cocoanut Grove, Florida, on March 23 (T. E. Snyder). At South 

 Jacksonville, Florida, on April 13, 1917, the writer found adults ready 

 to swarm in a telephone pole (white cedar) as high up as 12 feet from 

 the ground. In 1918 virginicus colonies were found at Miami Beach, 

 Florida, under dead cabbage palmetto trunks on the ground. The 

 writer observed adults flying on April 9 at 12 m. On February 21, 

 1919, at Labelle, Florida, winged pigmented adults ready to swarm 

 were found in a saw palmetto tree by F. C. Craighead. On Decem- 

 ber 30, 1918, W. E. Brown found workers damaging a post supporting a 

 mail box at Miami Beach, Florida; these workers are probably of the 

 species virginicus. Damage by species of Reticulitermes in southern 

 Florida is not common, and colonies of these termites are of com- 

 paratively rare occurrence. 



F. C. Bishopp, on May 3, 1916, noted a swarm of this species at 

 Shreveport, Louisiana. He writes : 



At 5.30 this afternoon observed a tremendous flight of termites on the simnyside 

 (west) of a warehouse near the river. The greatest numbers were emerging from the 

 timbers of a coal bin built against the outside of the warehouse but they were also 

 emerging from the loading platform all along this side. These planks seem to be 

 largely consumed by their galleries. 



The air in places was filled with the flying insects and places several feet square 

 near where they were emerging were largely covered by them. In smaller patches 

 (6 inches square) the wood was completely covered by the silvery wings. A few 

 soldiers, yellow wingless specimens, were seen crawling among the others. I am 

 informed that a large flight also took place last week. The planks of the loading plat- 

 form on the south side are almost completely destroyed, and I am told the entire build- 

 ing is mined and will soon have to be reconstructed.

R. virginicus possesses the three different reproductive forms as 

 does Jlavipes. Besides the normal colonizing forms, both the second 

 form type with short wing pads and the apterous type or third form 

 occur in colonies. This latter type is apparently rare. On June 4, 

 1915, at Falls Church, Virginia, a portion of a colony of virginicus was
