face. The twig had become a mere shell through decay and 

 probably also by the work of the ants, and in the chamber so 

 formed weer a number of larvae and a few pupae. There 

 were also pupae on the ground beneath the leaves, which the 

 ants immediately carried into the nest when disturbed. Three 

 other species of ants were collected close to the nest in this 

 same habitat — a single specimen of Stenamma brevicorne, one 

 of Myniiica pimctiventris and six of Lasiiis minutus. This 

 one colony was the only record for the species in the habitat, 

 but numerous colonies were found in the higher, drier and 

 more open forest. Some of the nests were in dead wood 

 which had become punky from decay others w^ere in the earth 

 beneath sticks and logs. There seemed to be no choice be- 

 tween these two situations as nest sites, the nests recorded be- 

 ing divided about equally between them. 



On September 17 a nest was found in a stump occupied 

 also by Lasins minutus. The two nests were very closely ap- 

 proximated, but the writer believes the relation to have been 

 a very simple case of plesiobiosis. Old beetle larvae burrows 

 had been utilized by aqiiia and from them a number of pupae 

 were taken and a single aleate female. On the eighteenth a 

 single isolated winged female was taken under a pine log in 

 the dry hardwood forest, and on the same day a colony was 

 found in the root of a rotten pine stump in which was a single 

 winged male. On the nineteenth two aleate males were se- 

 cured under debris on the west beach. A colony found on the 

 twenty-first, in the moist sand under a log on the north beach, 

 contained a wanged female. This colony also occupied a por- 

 tion of the under side of the log. 



A rather curious nest of this species was found on Septem- 

 ber 17. The colony was a large one and had constructed the 

 nest in the earth under a large granite boulder which was sunk
