REVISION OF NEARCTIC TERMITES. 129 



Santa Catalina Mountains, Arizona, in alder. The tree was a large, 

 live tree, with a dead part at the butt; a mere shell of dead part was 

 left, being eaten out by the termites. 



The habits of this species are similar to that of Termopsis angus- 

 ticollis Hagen. 



SWARMING. 



This termite swarms in June or July; winged adults have been 

 collected in June and July at Garcia and during July at Palmerlee, 

 Arizona (C. R. Biederman); in the Santa Rita Mountains, Arizona, 

 elevation 5,000 to 8,000 feet, July (F. H. Snow) ; and in the Santa 

 Catalina Mountains, Arizona, July 8 to 20 (Lutz and Rehn).

Subfamily Kalotermitinae Holmgren. 



Genus KALOTERMES Hagen. 



The species of the genus Kalotermes are not subterranean and are 

 able to bore through hard, dry wood. Instead of following the grain 

 in their burrowing, they excavate longitudinal oval chambers, inter- 

 connected by narrow passageways. Their dry, impressed pellets of 

 excrement (pi. 10) sometimes pack these chambers or are expelled 

 and fall to the groun*^' 



Colonies are founai n dead trees, logs, dead branches, and stumps. 

 Sometimes two species w^ill live in the same tree, log, or branch. 

 Species of Kalotermes are also fouind associated with species of Neo- 

 termes and Cryptotermes. 



Often the colonies are of very large size and the tree or log is com- 

 pletely riddled by burrows. 



Moisture does not seem to be so necessary, since Kalotermes can 

 survive in dry wood. 



The species of Kalotermes swarm at night. After the swarm the 

 winged insects settle upon tree trunks and logs and either before or 

 just after shedding the wings they begin to burrow directly into the 

 wood (pi. 17), if imder loose bark, or enter crevices. 



Like the species of Termopsis, the species of Kalotermes, Neotermes, 

 and Cryptotermes, which are not subterranean, infest wood directly 

 through holes, the burrows of other insects, decayed areas in trees, 

 and under loose bark. 



In Florida, on the offshore coral reefs or keys, no species of the 

 subterranean genus Reticulitermes were found ; only species of Kalo- 

 termes, Neotermes, Cryptotermes, and Prorhinotermes. Species of 

 Kalotermes, Neotermes, and Cryptotermes were common both on these
