Psyche 
[June- September 
olepis parvula, and Formica difficilis. Lashes neoniger, 
Formica argentea, F. subaenescens , and Camponotus nove- 
boracensis here approach their southern limits at low ele- 
vations in the eastern states. 
This list may be compared profitably with Wheeler’s lists 
for New England (1906), Nantucket (1928a), and Penikese 
(1926), and with Davis and Bequaert’s list for Long Island 
and Staten Island (1922). 
1. Stigmatomma pallipes Haldeman. East Falmouth 
Waquoit, Mashpee. (Naushon, August 31). This species 
is usually found in the beech-holly association that occurs 
sporadically in eastern Massachusetts. 
2. Ponera coarctata pennsylvanica Buckley. East Fal- 
mouth, Brewster. Woods Hole (Wheeler 1906). Much less 
common than in the New York region. 
3. Monomorium minimum Buckley. Woods Hole, Wa- 
quoit, Pocasset, South Yarmouth, North Eastham, South 
Wellfleet, Truro. July 15 (mating flight). Common in 
sand; also nests on the mounds of Formica exsectoides. I 
have found it only in the latter situation in northern New 
Jersey. 
4. Solenopsis molesta Say. Woods Hole, West Fal- 
mouth, Sandwich. 
5. Crematogaster lineolata Say. Woods Hole, Falmouth, 
East Falmouth, Pocasset, Sandwich, Hyannis, South Har- 
wich, South Chatham, Brewster, South Orleans, Truro. 
July 24- August 29 (Rochester, July 22). 
6. Myrmecina graminicola americana brevispinosa 
Emery. Woods Hole. Two specimens, under fallen leaves. 
7. Aphaenogaster treats Forel. Woods Hole, Brewster. 
Darker colored than specimens from Mississippi. 
8. A. fulva aquia Buckley. Woods Hole, East Falmouth, 
Waquoit, Pocasset. August 6-18. 
9. A. fulva aquia picea Emery. Woods Hole, East Fal- 
mouth, Waquoit, Brewster, Provincetown. July 15-Sep- 
tember 8.
