humeri and a pair on the mesonotum. The pilosity varies in different 
samples, however, and specimens are frequently partly denuded. 
Color usually medium ferruginous, but some samples are much 
darker; a Jamaican series is blackish-brown. 
The female is similar to the larger workers of the same nest series, 
apart from the usual caste differences, but the head averages a trifle 
broader (Cl 83-89), and the gastric dorsum is more or less distinctly 
shagreened over the basal segment, but usually not so strongly sculp- 
tured as is the eggersi female. Male unknown. 
Distribution: Occurs widely in countries bordering the Caribbean; 
actually reported from southern Mexico, Costa Rica and Panama ; 
Central America may be the original home of the species. It is well 
established in Trinidad and Tobago, Cuba and Jamaica, and southern 
Florida, doubtless after introduction through human commerce, at 
least in some of these places, but it has not been found on the South 
American mainland.

Biology: E. O. Wilson (unpubl. notes) kept a colony of gundlachi 
for over a month in Cuba, during which time it captured and con- 
sumed entomobryoid and sminthurid collembolans, but ignored podu- 
roids, a small cricket nymph, various mites and minute millipeds. 
Hunting is usually of the relatively immobile ambush type, which is 
to say that the ants approach the prey and, when close enough to de-
