REVISION OF NEARCTIC TERMITES. 137 



Canyon, Santa Catalina Mountains. Eggs and winged, pigmented 

 adults were present. 



On June 13, 1918, at Sycamore Flat, Santa Catalina Mountains, 

 Arizona, two dead first form adults of K. minor were found by F. C. 

 Craighead in a small pocket filled with pellets of excrement in a stag- 

 top of Gwpressus arizonicus 75 feet above the groimd. No hole to 

 the exterior was observed. Both insects, dealated young parent 

 adults, were dead and shriveled and the pocket was healed over by 

 10 to 15 years of annual growth. 



SWARMING. 



This species evidently swarms in July in Arizona. Winged adults 

 were collected at hght in Sabino Canyon, Santa Catalina Mountains, 

 Arizona, flying with K. huhhardi Banks on June 20, July 10, 11, 12, 

 13, and 22, 1918, by George Hofer, and July 6, and 28, 1919. 



The colonizing adults have dark wings. The incipient colonies 

 are small. 



No enlarged reproductive forms have been found. The first form 

 queens found by the writer at Cypress Point and Los Gatos were only 

 about 10 mm. in length, with the abdomen slightly distended.

KALOTERMES HUBBARDI Banks. 



For taxonomy see pp. 28-29. 



This species was named in honor of the late H. G. Hubbard, of the 

 Bureau of Entomology, who, with E. A. Schwarz, was one of the 

 pioneers in studying the habits of our native termites. Kalotermes 

 huhhardi occurs in Lower California, California, Arizona, and prob- 

 ably in northern Mexico. 



One of the most triking characteristics of this species is the greatly 

 elongated, club-shaped third joint of the antennae in the soldier caste. 



K. huhhardi is associated with K. mmor Hagen in the dry wood of dead 

 Cottonwood, poplar, walnut, and ''palo verde" trees in canyons and 

 along streams in Arizona. It can be readily distinguished from minor 

 (which is dark bluish-black) by its pale brownish-yellow color. These 

 two species often completely riddle the wood of trees and logs. (PL 20.) 



Hubbard collected this termite near Tucson, Arizona, as early as 

 1896 (Dec. 30) in a hardened wound — a wood pecker's hole — in the 

 stem of the giant cactus {Cereus giganteus). The colony was entirely 

 isolated, being 5^ feet from the ground; this colony was small. Hub- 

 bard also found that this termite was the species commonly found 

 damaging the rafters of "adobe" buildings in the vicinity of Tucson. 

 (Pis. 21 and 22.) 



On December 17, 1901, Theo. Pergande notes that termites 

 (huhhardi) were received by the Bureau of Entomology; all
