Lasius niger Linn. var. neoninger Em. have associated with 

 them Formica pallide-fulva Latr. sub sp. nitidiventris Em., La- 

 sius daviger Rog. , L. flaviis Linn, sub sp. myops Forel and /,, 

 niger Linn. var. americanus Em. 



Lasius daviger Rog. have associated with them Monomorium 

 minutiim Mayr, var. minimum Buckley, Solenopsis molesta Say 

 and Myrmecina latreillei Curt. var. brevispinosa Em. 



Lasius niger Linn. var. americanus Em. have associated with 

 them Formica pallide-fulva Latr. and Solenopsis molesta Say. 



Prenolepis parvula Mayr have associated with them Monomo- 

 rium minutum Mayr var. minimum Buckley and Solenopsis mo- 

 lesta Say. Aph<znog aster fulva Rog. have associated with them 

 Ponera coarctata Latr. sub sp. pennsylvanica Buckley and Solen- 

 opsis molesta Say. 



Myrmica lobicornis Myl. have associated with them Lasius 

 jiigcrvar. americanus Em. and Solenopsis molesta Say. 



Cremastog aster lineolata Say have associated with them Lasius 

 niger Linn. var. neoniger Em. I have also found mixed pupa 

 of Cremastogastcr and L. nuniger in the same nest together. 



From the literature that I have read before I commenced to 

 study Formicidae in their natural formicaries I was led to suppose 

 that all of our ants were deprived of their wings during or shortly 

 after their marriage flight or swarming period. But this seerns 

 not to be the case, for I find winged forms, as stated below, to 

 have lived through our cold Winter months, and further obser- 

 vations will, in all probability, add more to this list. In neither 

 case were there to be found any larva or pupa of the ants in the 

 nests at this time. 



WINGED FORMS. 



Camponotus herculaneus Linn, sub sp. ligniperdus Latr. I 

 have found winged forms of males and females April 2oth in a 

 rotten hard pine log. 



Camponotus castaneus Latr. sub sp. americanus Mayr. I have 

 found winged males and females to be quite common April 28th 

 under stones. 



Prenolepis imparts Say. I have found winged males and 

 females April I5th under stones. 



Prenolepis parvula Mayr. I have found winged males and 

 females May 4th under stones.
