REVISION OF NEARCTIC TERMITES. 169 



In Arizona, Barber and Schwarz collected winged adults at 

 Williams "29/7." 



At Lincoln, Nebraska, winged adults have been found in April and 

 September. 



In Kansas, R. tibialis has been found swarming in September (2 

 and 11), at Manhattan (F. A. Marlatt). 



In Texas, winged adults have been collected flying at Beeville, 

 November 1, 1895 (Schwarz); Uvalde, May 7, 1917 (Snyder); Dallas, 

 December 16, 1910 (Pinkus), during fair and warm weather after a 

 recent rain; Piano, October (Tucker); and December 19, 1917, at 

 Victoria (Mtchell). Mitchell's notes on this swarm are: 



White ants emerging by thousands from crevice in concrete sidewalk on Santa Rosa 

 Street, Victoria, Texas, December 19, 1917. 1917 has been very dry the entire year. 

 October and November have been unusually cold, freezing and frosting many times. 

 December 19 was a moderately warm day. The ants took wing as soon as they reached 

 the edge of the sidewalk. A few soldiers and workers were around the exit crevice 

 and seemed to be directing the winged ants to go in the same direction. 



At Uvalde, Texas, the writer found this species swarming on May 

 7, 1917, in moist bottom land along the Leona River. The swarm 

 occurred before 1.30 p. m., when flying adults were observed. On 

 May 3 the temperatm-e at Uvalde had been 97° F., with a humidity 

 of 40° to 50° (low barometer). On the 5th there were high winds, 

 hail, and heavy rain, which was continued in the morning of the 6th, 

 being markedly cool on the 6th and 7th. After this hot weather on 

 the 3d and the rain on the 5th, termites (R. tibialis Banks) were 

 ready to swarm, which occurred on the 7th. 



In southwestern Texas termites usually swarm after rainfall, 

 when the ground is in better condition for the establishment of 

 colonies. 



At Ponca City, Oklahoma, this termite was found injuring the 

 roots of a privet hedge on August 11, 1916, by Mr. A. Jackson. He 

 was successful in getting rid of the termites by the liberal use of 

 water around the roots, plowing a furrow with a cultivator on either 

 side of the hedge and running water in the furrows. 



Reproductive forms have been found by Harvey and Champlain. 

 On July 16, 1915, B. T. Harvey noted reproductive forms in a colony 

 which proved to be three females and two males of the type with 

 wing pads (second form). These were in a colony m a scrub white 

 oak root collected on April 26 in the Garden of the Gods and re- 

 moved to Colorado Springs for observation. These forms quite prob- 

 ably developed between April 26 and July 16, since the root was re- 

 moved. (PL 30.) 



A. B. Champlain, on April 12, 1915, at the Garden of the Gods, 



Colorado, found a small colony under a stone, which consisted of 



workers, soldiers, and a smaU apterous queen of the third form 



C'ergatoid"). This queen has the chitinized parts of a grey pig-
