Fig 1. A six-cell colony of S^. geminat a. Two glass culture 

 tubes plugged with cotton and containing water or 

 dilute honey, a dish of insect pupae, and part of a 

 boiled egg are on the left. Alate sexuals are con- 

 centrated in the reat top cell. 



Fig 2. A miniature nest cell. The nest cell has a layer 

 of Castone (dental casting compound) in the bottom 

 and an entry port in the side. A wad of wet cotton 

 helps maintain high humidity. The wall of the large 

 petri dish is coated with Fluon to prevent escape 

 of the ants. The large petri dish top is normally 

 taped securely to the bottom and labeled.
