ground under oak trees. Though only a small proportion were 
inhabited by ants, fourteen colonies of six forms of ants were 
found, including one that has not hitherto been recorded from 
New England. There follows a list of the species found. 
1. Myrmica punctiventris Roger. Woods Hole, five colonies. 
Workers, queens, males, eggs, larvae, and pupae. The four queens 
found were all dealated; three of these were in one colony, that 
also contained nineteen males and one male pupa. 
Identified by Prof. W. M. Wheeler who has also verified 
the identification of number 4 below. 
2. Leptothorax curvispinosus Mayr. Falmouth, one colony. 
One dealated queen, over 100 workers, numerous eggs and larvae, 
a few pupae. 
3. Leptothorax curvispinosus ambiguus Emery. Falmouth, 
one colony. Workers, a few eggs, larvae, and pupae. This gall 
was under the same tree as that containing the colony of the 
typical form of the species. 
4. Harpagoxenus americanus Emery. Tarpaulin Cove, 
Naushon Island, August 30; one colony. One dealated queen, 
nine workers; 152 workers of Leptothorax curvispinosus , several 
eggs, 21 larvae, 5 pupae. The pupae appear to be Leptothorax, 
and several of the Leptothorax workers are evidently callows. 
The species is recorded from the District of Columbia; Beatty, 
Pennsylvania; Bronxville, New York. L. curvispinosus is its 
usual host (see Wheeler, 1910. Ants, p. 494). 
5. Tapinoma sessile Say. Cotuit, Pocasset, Falmouth, 
Naushon Island; five colonies. Workers, dealated queens, eggs, 
larvae, pupae. One of the colonies contained fifteen dealated 
queens. 
6. Lasius niger, var. americanus Emery. Woods Hole, one 
colony. Workers, pupae. A populous colony (104 workers, 12 
pupae), but no eggs, larvae, or sexual forms were found.
