to rear, and the posterior face is more or less concave and overhung 
by the slightly produced posterodorsal nodal border, but a tendency 
in this direction is seen in some northern specimens, for instance, in 
a worker from the Ouachita Mts. of southwestern Arkansas, and 
one from Schooler Lake, Choctaw Co., Oklahoma (W. L. Brown). 
The geographical gap between Honduras and eastern U. S. is now 
being filled in to some extent. Already in 1911, W. M. Wheeler had 
collected specimens in Guatemala (Quirigua and without locality 
except for the country), and now S. and J. Peck have sent samples 
from litter berlesates in Veracruz, Mexico: near Cordoba, and in 
the canyon of the Rio Metlac, near Fortin de las Flores. It should 
only be a matter of time until we have samples from east Texas and 
Tamaulipas. This case is paralleled by that of Cryptopone gilva, 
another ponerine that ranges from the U. S. down through the up- 
lands of Mexico and Central America as far as Panama. 
P. goliath was taken at Zent, Costa Rica by N. A. Weber, the 
collection being the first male known for the species, date 17 July 
1956. A worker apparently belonging to this species, but a little 
smaller than the types from Costa Rica, and with a very deep con- 
striction between postpetiole and succeeding segment, comes from 
Caves Branch, British Honduras (berlesate, S. and J. Peck).
