beneath a flat scale of limestone rock on the north beach with 

 winged ■ females of Lasins claviger and Myrmica scabrinodis. 

 All four of these females were at the very edge of the water, 

 where the rock was cold and wet. Directly back of this spot, 

 under driftwood on the dry sand behind the outcrop, another 

 winged female was collected with two aleate females of M. 

 scabrinodis. 



The species was confined to the hardwood forest, except 

 for the emigrating females, where it inhabited both the low, 

 damp spots and the dry areas. The workers were not wide 

 ranging and were never noted away from the nests, which 

 leads the writer to believe that the species was more plentiful 

 than the records would indicate, the close restriction to the nest 

 rendering the colonies inconspicuous. 



16. Lasins (Acanthomyops) clainger Roger. — ^The only 

 record for this species is a single winged female taken under 

 beach debris on the north beach, September 21. This indi- 

 vidual might well have come from the mainland, if the flights 

 of L. americamis are any criterion. 



17. Formica pallide-fttlva I^atr. subsp. nitidiventris Emery. 

 — This species must have been very rare on the island as the 

 only record is a single isolated worker that was taken on the 

 bare sand of the high west beach. 



18. Formica fusca L. var. subsericea Say. — Notwithstand- 

 ing its wide geographical and habitat range, F. subsericea was 

 not common on the island. It nested without exception in rot- 

 ten wood, and preferably in that which was underground, i. e., 

 either roots of stumps or partially buried logs. On one occa- 

 sion a hill about eight inches high was found in the low hard- 

 wood forest, and this contained the largest colony found. It 

 was a dome-shaped mound, much as one would expect from 

 F. glacxalis, but on being opened it proved to be the site of
