 they can get their living. 



A great deal more could be said, but this will have to suffice 

 for the present. The following is a list of ants that I have found 

 to be associated together, but it should be remembered that 

 Ponera coardata Latr. sub. sp. pennsylvanica Buckley, Solen- 

 opsis molesta Say, Monomorium minutum Mayr, var. minimum 

 Buckley, are Myrmecophilous ants. Formica sajiguinea Latr. 

 sub. sp. rubicunda Em. is a slave-making ant, and may be classed 

 as a Myrmecophilous sp. 



Camponotus castaneus Latr. sub sp. americanus Mayr, have 

 associated with them Lasius niger Linn., L. niger \^. ameri- 

 tanus Em. 



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

 opsis molesta Say, Camponotus herculeanus Linn. sub. sp. and 

 var. pictus Forel. Workers of Tapinoma sessile Say and For- 

 mica fusca Linn. var. subsericea Say. 



Formica pallide-fulva Latr. have associated with them Lasius 

 niger Linn., L. niger Linn. var. americanus Em., Formica pal 

 lide-fulva sub sp. nitidiventris Em., Prenolepsis parvula Mayr, 

 Formica pallide-fulva sub sp, fuscata Em., Aphanogaster fulva 

 Rog. and Solenopsis molesta Say. 



Formica fusca Linn, have associated with them Ponera coarc- 

 iata Latr. var. pennsylvanica Buckley and Solenopsis molesta Say. 



Formica fusca Linn. var. subsericea Say have associated with 

 them Formica pallide-fulva sub sp. nitidiventris Em. and Solen- 

 opsis molesta Say. 



Formica pallide-fulva sub sp. nitidiventris Em. have associated 

 with them Premcetis parvula Mayr and Solenopsis molesta Say. 



Formica sanguinea Latr. sub. sp. rubicunda Em. have asso- 

 ciated with them as slaves Formica fusca Linn. var. subsericea 



Say. 



Lasius flavus Linn. sub. sp. my ops Forel, have associated with 

 them Aphcenogaster fuha Rog., Lasius niger Linn., americanus 

 Em. and Tapinoma sessile Say.
