Cape Cod Ants 
75 
10. Myrmica punctiventris Roger. Woods Hole, East 
Falmouth, Waquoit, Mashpee. September 7-13. (Fairhaven, 
August 13). Mating flight, September 13. Common in old 
nuts and galls and under fallen leaves. 
11. M. Isevinodis bruesi Wheeler. Woods Hole. July 
29-August 28. This form was described from specimens 
taken in the woods adjoining the Fay Rose Gardens. It is 
now the dominant ant in these woods, but I have been 
unable to find a single specimen in any other place. The 
numerous nests seem to represent branches of a single 
family, since transfers of workers never lead to fighting — 
in spite of the fact that the species is very pugnacious and 
has the most painful sting of any ant I have encountered 
in the northeastern states. 
12. M. scabrinodis sabuleti Meinert. Woods Hole, Fal- 
mouth, Falmouth Heights, East Falmouth, Pocasset, Truro. 
August 14-September 6. 
13. M. scabrinodis schencki emeryana Forel. Woods 
Hole, Sandwich, South Harwich, Chatham. 
14. Harpagoxenus americanus Emery. Woods Hole, 
West Falmouth, Sandwich. July 12-August 14. Sexual 
pupse still present August 14. Found with Leptothorax 
curvispinosus and with L. longispinosus. I have taken 
this at three other unrecorded localities— Mendham, New 
Jersey; Cold Spring Harbor, Long Island, New York; Fair- 
haven, Massachusetts. 
15. Leptothorax longispinosus Roger. Woods Hole, 
East Falmouth, Sandwich, Mashpee. 
16. L. curvispinosus Mayr. Woods Hole, Falmouth, 
West Falmouth, Waquoit, Mashpee, Provincetown. August 
1-7. Sexual pupse present, July 4-August 7. Common in 
old acorns, nuts and hollow twigs.

Falmouth.
