Three were found under flat flakes of limestone so close to the 

 water that they barely escaped the higher waves which kept 

 the rocks wet and cool. The other three were found higher 

 up on the beach in drier places beneath beach debris. Aleate 

 females of Lasius m'mutiis and a single one of Lasiiis claviger 

 were taken with them. 



The species was noticeably confined to the driest areas, the 

 three winged males just noted obviously hardly counting as 

 exceptions. It was not common on the island, though probably 

 more plentiful than the records would indicate. The ants are 

 very secretive and the nests always concealed effectively, both 

 factors which would tend to cause the species to be overlooked.

10. Tapinoma sessile Say. — This species was first noted 

 on September 17, when a small colony was found in a decayed 

 log on the beach. The log was in the high grass and willow 

 bushes, well back from the water and near the forest, and was 

 very soft and so wet that water could easily be squeezed out 

 of it. Neither larvae nor pupae were found. The species was 

 next noted on the twentieth in the low hardwood forest. In the 

 bare earth in the path that ran through the forest, several 

 small mounds were noted, all appeared to be uninhabited, but 

 a single ant of this species was found in one. Later other col- 

 onies were found in the edge of the forest along the north 

 beach. These were in moist sandy loam and numbered about 

 three hundred individuals to the colony. There were usually 

 a number of yellow pupae, but larvae were rarely noted. A 

 single colony was found under a log in the low damp hardwood 

 forest, on September 22, and here, too, an abundance of yellow 

 pupae was noted.
