slightly pitnky with decay. All of these were solitary, and 

 there was no colony in the vicinity. Collected with them were- 

 four w^orkers of another genus, Aphaenogastcr tennesseeiisis. 

 Both of these records were obtained in the dry hardwood for- 

 est, and later in the day, in the same habitat, a large colony of 

 the Camponotus was found. It was located in a dry maple 

 stub, ten feet high and fifteen inches in diameter. The center 

 of the stub was comparatively firm, but the outer part had 

 become punky and rather soft. To the height of six feet the 

 stub was a network of passages, the major ones being parallel 

 and vertical, with short, cross openings between them. The 

 colony was confined to the central part of the stub, in a cylin- 

 der of perhaps ten inches diameter in the best preserved part 

 of the wood. It required considerable effort to open the nest 

 with a light belt axe, and when the interior was laid bare a 

 large number of winged females were immediately seen. They 

 were very secretive and at once retreated to lower recesses of 

 the nesit. Specimens were secured including a single aleate 

 male — the only one seen. There was a surprisingly 

 small number of pupae, a few chambers in the lower half of 

 the nest being partially filled with them. It is interesting to- 

 note that there was not a trace of the presence of this large 

 colony on the exterior of the stub — no evident openings to the 

 surface, no accumulation of wood dust at the base, nor any- 

 other indication of so extensive an amount of work. It was 

 only by the presence of a few individuals at the foot of the 

 stump that the colony was found. It must have been an old- 

 one in which the construction period was nearly over, and nat- 

 ural processes had removed the evidences of the work. 



On September 20, in the lower and more damp hardwood 

 forest another colony was found. This occupied a badly de- 

 cayed poplar log, six feet long and six inches in diameter. The
