SWARMING. 



C. tenuirostris Desneux swarms at night. E,. E. Kunze collected 

 winged adults flying as early as June 25, 1S99, in the Huachuca 

 Mountains, Arizona. E. A. Schwarz also collected this species in the 

 Santa Catalina Mountains, Arizona. F. H. Snow collected adults 

 swarming in July in the Santa Rita Mountains, Arizona, at an ele- 

 vation of 5,000 to 8,000 feet. Flying adults were also collected by 

 C. R. Biederman in July and August at Palmerlee, i\.rizona, also at 

 Garcia. Oslar collected adults swarming at Nogales, Arizona, on 

 July 1, 1903. M. Chiisman noted a swarm at Brush Corral Station 

 (elevation 3,520 feet) in the Santa Catalina Mountains, Arizona, in 

 July, 1915. The adults commenced flying at dusk on July 18, coming 

 readily to light. The ground was damp, since the first rain on July 12. 

 On July 20 adults were collected at 10 p. m., there being a fine drizzle 

 at the time. Prof. W. M. Wheeler collected adults in Post Canyon 

 in the Pinaleno Mountains, Arizona (elevation 5,000 to 6,000 feet), 

 on July 17 and 18, 1917. George Hofer collected adults at light in 

 Sabino Canyon, Santa Catalina Mountains, Arizona, on July 7, 1919.

CONSTRICTOTERMES (TERMES) CINEREUS Buckley. 



For taxonomy see pp. 73-75. 



Buckley described this species in 1862 from specimens of nasuti 

 and workers. The type locality is San Saba County, Texas. Wheeler 

 found this species common in the vicinity of Austin, Texas, according 

 to Desneux (1905), who redescribed the soldier and worker castes. 

 Desneux (1905) states that this species is a sort of a reduction of 

 tenuirostris, which is very nearly related but without doubt distinct. 

 The winged adults were unknown. Desneux states that Buckley's 

 descriptions are, for the most part, fantastical. 



Buckley (1862) writes: 



It was about sunset on the 22d of October, 1860, when I first saw this species, in 

 San Saba County, Texas, in a field where both workers and nasuti were carrying home 

 seeds of grasses and weeds. They marched in dense columns along pathways leading 

 to a hole near the base of a stump, into which they entered. Others were marching 

 outward in search of provender. The nasuti are about one-fourth to one-fifth of the 

 entire community. They dwell in the ground where they have rooms, seldom more 

 than one to two inches long, connected by tunnels. They march with heads erect 

 and thrown backwards over the thorax, carrying their loads with their mandibles. 



Subsequently, while engaged in the geological sm'vey of that and the adjoining 

 counties, I met them frequently. After rains, which are of rare occurrence in that 

 climate, they make semicylindrical tubes which lie on the surface of the ground to 

 the length of from 3 to 6 inches. These arched ways sometimes intersect each other, 

 being connected with chambers below. They rarely work by day above the surface
