all of the stump but a small portion on the north side, where 

 a small colony, two hundred or less, of Aphaenogaster ftdva 

 ^ubsp. aqida was found. (See notes under that species.) No 

 relations of any nature were visible between the two colonies. 



On the following day, September i8, a still larger colony 

 was found in an oak stub in the same habitat. This stub was 

 thirty inches or more in diameter at the base, and on the west 

 side was badly decayed, making a very soft section of perhaps 

 •one-third the volume of the entire stub. It was probably a 

 place that had started to decay previous to the death of the 

 tree. To a height of five feet this weakened region was liter- 

 ally filled with ants — workers, winged males and females — and 

 with pupae. Here, as in the former colony, the males predom- 

 -inated two or three to one, and were noticeably the more slug- 

 gish. The nest extended only a little distance into the earth, 

 less than six inches, and was well concealed as there were no 

 -openings or entrances except at the base of the stub and these 

 were in the earth close to the wood. No ants were seen out- 

 side the nest, a notable difference from the previous colony. 

 On the same stub were found a few specimens of Aphaeno- 

 gaster tenncsseensis, but no colony was discovered. 



A smaller colony was found in the low hardwood forest in 

 the interior of the island, in a large, badly decayed oak log, 

 on September 20. A single winged female was taken in this 

 colony. No males were noted, and no pupae were present. On 

 the same date a single aleate female was collected in a very 

 damp, rotten poplar stump in the same habitat, but at a distance 

 from the colony, and another aleate female was seen here but 

 not collected. The next day, in a clearing in the dry hardwood 

 forest near the beach, an isolated and very inactive dealeated 

 female was found in a small excavation in the earth beneath 

 a leaf. On September 17 another dealeated female was taken
