wood was so soft and wet that drops of moisture could easily 

 be pressed out between the fingers. The colony occupied 

 about one foot of the log, and was not a large one. Two 

 small chambers full of pupae were opened and a few immature 

 ants and a queen were found. The same day three individuals 

 of this species, all workers, were collected in a wet, decayed 

 pine log on the bare limestone outcrop on the north beach, less 

 than ten feet from the water's edge, where no other ants were 

 setn. On September 22 a single dealeate female was found 

 alone just beneath the bark of an oak log in the hardwood for- 

 est. The log was only slightly decayed, but the ant lay in a 

 small depression in the wood under the bark. It looked as if 

 the ant had excavated the place for herself. Xo other ants 

 Avere noted. The same day another small colony of this species 

 was found in a dogwood thicket at the edge of the hardwood 

 forest and the beach. It was located in the driest end of a 

 small pine log, where a few pupae, forty or fifty in number, 

 were uncovered, together with some pale, recently hatched 

 -workers and the queen. 



This completes the records for the species on the island. 

 It was not abundant and the workers were not wide-ranging. 

 With the exception of the three isolated workers found near 

 the water, the species was confined to the hardwood forest, and 

 preferred the noticeably dry places. 



21. Camponotus herculeanus L. subsp. ligniperda Latr. 

 var. novehoracensis Fitch. — A colony was found in a large 

 punky pine log beneath the willows on the east beach on Sep- 

 tember 17. The log was too large and sound to be opened, 

 but, though few ants were visible, there was evidence of con- 

 siderable work in the form of accumulations of small piles of 

 wood-dust at the ends cf the log. A few ants were at work 

 when the log was first noted, at six a. m. on a cold wet morn-
