ANTS COLLECTED IN BRITISH GUIANA BY 

 MR. C. WILLIAM BEEBE. 



By William ^Morton Wheeler, 

 Forest Hills, Mass. 



]\[r. C. William Beebe of the New York Zoological Park recently 

 sent me for identification a series of ants from British Guiana. The 

 specimens had been collected with an umbrella Sept. 15 to 20, 1917, 

 near the Penal Settlements in the Bartica District from an area of 

 only twenty square feet of bushes in a clearing. There are 156 spec- 

 imens representing 42 distinct forms. Most of these are well-known 

 neotropical species commonly found running over foliage, but fifteen 

 of them (indicated by asterisks in the list) have not before been re- 

 corded from British Guiana and two of them are new to science.
