 Santa Maria 



The maps on the facing page and following page are indexes to the locations of colonies 

 within map 501, Santa Maria. Note that all colonies on the map are not numbered consec- 

 utively from north to south, since many previously unreported colonies have been added 

 since initial colony numbers were assigned by Varoujean (1979). On the pages following 

 these two maps, all colonies are listed sequentially and a detailed map of each is provided.
