Quite a large quantity of a yellow seed unknown to me came in a 

 mixed lot of ants in one vial. Mr. Crew states that he does not 

 remember mixing any of the species found, but put each colony into 

 separate vials. The following are the species from one vial, that con- 

 tained the seeds : 



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



Formica fusca, L., var. subsericea, Say. 



Formica lasioides, Em., var. picea, Em. 



Myrmica scabrinodis, Nyl., var. Schencki, Em, 



The last species seemed to predominate greatly in numbers. So far 

 as I know, this is the first time that any of the species here mentioned 

 have been listed as being found in company with ants. In the determi- 

 nation of these insects I have received valuable assistance from Prof. 

 Herbert Osborn, Prof. L. O. Howard, Mr. Ashmead, Mr. Coquillett, and 

 Mr. Blanchard ; and not only for these, but for many others not yet pub- 

 lished that I have found to inhabit ants' nests in Massachusetts.
