into the wood. Then they plug the opening, thereby sealing them- 
selves in. Colonies grow very slowly, are never confined to a single 
chamber and never contain more than a few thousand individu- 
als. Piles of pellets on the floor may be the first evidence of in- 
festations. Other tell-tale evidence consists of pitted and rough- 
ened surfaces of infested floor surfaces, door frames, and other 
wood. 
Nonsubterranean termites usually are less injurious than sub- 
terranean species in the United States. However, large public 
and other buildings in several Florida cities; New Orleans, Lou- 
isiana; Savannah, Georgia; Charleston, South Carolina; and less 
commonly elsewhere, have been seriously damaged (672). 
Incisitermes snyderi (Light) is the most widely distributed and 
injurious of the eastern nonsubterranean termites. It occurs from 
South Carolina to Florida and west to Brownsville, Texas, mainly 
along the coast. Infestations occur in the woodwork of buildings; 
in untreated utility poles, and in dead trees, logs, and branches. 
Winged adults have yellowish heads and are 11 to 12 mm. long. 
Soldiers are 7 to 8 mm. long and have the anterior margin of the 
pronotum dentate. 
Incisitermes schwarzi (Banks), the southern dry-wood termite, 
occurs in Florida south of Pensacola, where it is the commonest 
species. Infestations are found in the woodwork of buildings, in 
the bases and tops of utility poles, and in dead trees, logs, and 
stumps. Winged adults have yellowish heads and are 15 to 16 mm. 
long. Soldiers resemble the soldiers of J. snyderi except that the 
anterior margin of the pronotum is not dentate. 
Kalotermes approximatus Snyder has been recorded from 
northern Florida; New Orleans, Louisiana; and southern Vir- 
ginia. Infestations occur in the woodwork of buildings, in living 
and dead trees, and in logs and stumps. Winged adults are black- 
ish in color (249). 
Neotermes jouteli Banks occur in southern Florida, including 
the Keys. It occasionally occurs in the moist foundation timbers 
of buildings. In nature, it lives in dead trees and in logs and 
branches lying on the ground. Adults are yellowish or light cas- 
taneous and about 10 mm. long. .
