sawing out the section containing the nest it \v;is split open 

 with an ax. There were many hundreds of ants, and from t he 

 first blow to the last they were busy, each class to its own 

 work. The large, heavy-jawed individuals, comprising about 

 two-lhirds of the colony, came out to fight. They were 

 active and aggressive, spreading out 3 feet from the log in 

 every direction, seeking their enemy. In defense they were 

 far inferior to Neoponera villosa. The larvse were very few 

 and were cared for by small, slender workers. February 15, 

 1910, a colony was found in the center of a decayed willow 

 tree, clustered in several small connected cells, being packed 

 closely for hibernation. The colony consisted of four winged 

 forms, 45 nurses, 61 medium-sized workers, and 74 large 

 foragers. This colony was shipped to Dallas for observation 

 (Mitchell). The winged forms all died en route. The remain- 

 der were placed in a breeding-cage. On May 2 a cluster of 

 eggs was noticed surrounded by workers. The eggs hatched 

 in due time, but the larvae developed very slowly. They were 

 separated into groups June 3. July 9 a cocoon was observed 

 inclosing one of the largest larva. July 15 two more cocoons 

 were formed. July 29 a winged male hatched out (H. Pinkus). 

 September 28, 1911, a colony of approximately 1,000 adults 

 was located in a decayed willow log. The soft parts of the 

 wood had been removed from the inside of the log. making 

 irregular cells. The colony consisted of winged males and 

 females, one wingless female, soldiers, workers, nurses, and 

 pupte. The winged forms were more numerous than the 

 wingless. The nurses were very faithful to their charges. 

 On February 14, 1911, a colony was found in a fallen cotton- 

 wood with 300 or 400 winged ants. 



Camponotus planatus Roger. 



A few workers were found on low ground May 8, 1909. 

 They were shy and hid quickly. 



Camponotus fallax (Nyhtrider) rasilis Wheeler. 



This species was taken November 6, 1902, on cotton, and 

 also September IS, 1904 (W. K. Hinds). 



Camponotus fallax (Xyhtnder) discolor Buckley. 



A colony of this ant was found in a stem of Xanthinm, 

 December 29, 190X, consisting only of queens, males, and 

 workers. On January Hi, 1909, a similar colony was found 

 in the same species of plant. On May IS, 1909, a colony was 

 taken from an old live-oak twig gall of Anif>/ii(>(>/ip*. < >n 

 February 25, 1910, a large colony of winged males, females, 

 and workers was found under the bark of a dead willow tree
