Dr. Williams took a dozen workers which are indistinguish- 
able from specimens from various parts of the American tropics 
(Southern Florida, West Indies, Mexico, Central and South 
America) in my collection. A variety of the species, quadri- 
dentata F. Smith, occurs in the East Indies.

3. Tetramorium guineénse (Fabricius) 
Seven workers and -three dealated females. This is a very 
common tropicopolitan species, which occurs also in the Gala- 
pagos Islands and even in hot-houses of temperate regions as 
it is frequently introduced with plants from the West Indies 
and the adjacent mainland. A portion of the rather extensive 
synonymy of this ant is given in my “Ants of the Galapagos 
Islands,” p. 274.
