EEVISION OF NEAECTIC TERMITES. 177 



M. Chrisman found a small colony of workers and soldiers of 

 R. liumilis in Bear Canyon, Santa Catalina Mountains, Arizona, on 

 August 6, 1913, in a small, standing dead Chihuahua pine. 



This termite occurs at high elevations in the Santa Rita and 

 Pinaleno Mountains, reaching as high as 5,000 to 8,000 feet in the 

 Santa Ritas (rather indefinite), and 5,000 to 6,000 feet (Post Canyon) 

 in the Pinaleno Mountains (Wheeler). In the Santa Catalinas the 

 writer found this termite in Sabino Canyon but could not find it or 

 its work at Soldiers' Camp on Mount Lemon, in May, 1917 (elevation 

 7,700 feet) — timber, white pine, Douglas fir, fir, and spruce — or even 

 in lower stands of yellow pine at 7,000 feet and lower. 



Near Nogales, where the vegetation differs from that near Sabino 

 Canyon — that is,giant cactus, and {Opuntia), "Palo Verde," mescal or 

 Agave, Spanish bayonet or Yucca, and ocotillo (Fouquieria splendens), 

 etc. — the writer found this termite in Calabasis Canyon (15 miles west 

 of Nogales) on May 20, 1917, in the hard wood of oak stumps and 

 logs. It also occurred in Potrero Canyon. The foothills are bare, 

 sand, rock, and gravel. The mountain canyons contain oak, mesquite, 

 walnut (rare), catclaw {Mimosa), and desert willow (Chilopsis 

 linearis). Along the Santa Cruz River, willow, sycamore, and cotton- 

 wood trees are found. 



George Hofer found this termite on February 3, 1917, damaging 

 the beams of an adobe building at Alamo Ranch, near Sabino Canyon, 

 Santa Catalina Mountains. The workers constructed their earth-like 

 tubes up over the adobe walls to Douglas fir roof joists and bearing 

 These covered passageways or tunnels were on the inner surface of 

 the adobe walls. There was only a single passageway to each section 

 of wood. The walls of these tunnels were of paper-like thickness. 



Prof. W. M. Wheeler collected this termite at Oracle (Pinal 

 County), Arizona, on March 13, 1919, and in Grant Canyon (Graham 

 County), on March 21, 1919.
