bers during a slow, steady rain. Arnitermes (?) perplexus Banks 

 swarmed at the same time. Parman's notes are as follows: 



For the last few days there had been a low barometer, with rising humidity and an 

 occasional flurry of wind, temperature ranging from 98 and 73. To-day about 12:30 

 it began to rain, a moderate breeze following the rain, but quieted down soon after 

 the rain began to fall. About 2 inches of rain fell iintil about 2 p. m.; after this time 

 a slow steady rain followed until 4 p. m. During this time the air was full of the 

 swarming termites. Several hundred could be seen in any direction. After the rain 

 stopped no more termites could be seen, but the walks and the clean ground were 

 literally covered with wings; there was scarcely a square yard in which no wings 

 could be found in the vicinity of the laboratory. In many places from 300 to 500 

 could be found on a square foot. (It must be remembered that two species were 

 swarming.) Many earth cells have been noticed in the more moist places in yards 

 and irrigation places during the last month. 



The shedding of the wings was sometimes noticed while the insect was in the air. 

 A wing would break off and fly away from the adult, which, in an unsteady manner, 

 would finally fall to the ground. Some adults were observed to fall to the ground 

 with wings intact, but would later fly again unless the wings were loosened in the 

 attempt. 



Ants were observed to destroy large numbers of the termites after they lost their 

 wings. 



Near Uvalde, Texas, on May 3, 1917, tlie writer found colonies 

 with nymphs of the first form with long wing pads, and on May 5, 

 in a moist pasture near irrigation north of Uvalde, the writer found 

 a large colony under a cow chip on grass soil with winged mature 

 adults present ready to swarm. The}" occm-red under the cow chip 

 and in the soil. There were earthen tubes on the soil. The cow 

 chip was under a small bush. There was a heavy rain on May 5 

 and 6. 



The egg is white, slighth^ reniform, and approximately 0.55 to 

 0.60 mm. in length.

This termite, found in Arizona, apparently has similar habits to 

 A. tubijormans of Texas, which it closely resembles. A. arizonen&is 

 has been found at Fort Grant (Graham County) (Hubbard) ; Oracle 

 (Schwarz), (Wheeler) and Ray Junction (Barber) (Pinal County "); in
