acute, the dorsal low and rounded and alternating with 
the ventral ones so that all may be seen from a position 
directly dorsad. The more basal of the two ventral 
teeth is the larger, and this fits into the notch mentioned 
above just lateral to the clypeal apron. The apical bor- 
der distad of the two large double teeth at the angle with 
two more blunt, massive double teeth, which are well 
separated; these followed by a smaller acute tooth just 
before the acute, stoutly spiniform apex. Seen from the 
side, the mandibles are nearly twice as thick dorsoven- 
trally as in pallipes, and not quite so strongly projecting 
anteriorly; the apices somewhat recurved. 
The alitrunk is very similar to that of small pallipes 
workers, but perhaps very slightly more slender; the 
rounded lamellae at the base of the propodeal declivity 
smaller. The petiolar node is very slightly longer than 
broad seen from above, much as in smaller workers of 
pallipes. 
Sculpture throughout less pronounced than in pallipes, 
the head and thorax shining to the naked eye. Seen at 
very high magnifications, the dorsum of the head is sown 
with very small, regular punctures which are separated 
from each other by plane, shining surfaces which do not 
form the fine longitudinal costulation or rugulation seen 
in the forms of pallipes. Clypeus very indistinctly and 
irregularly longitudinally striate ; mandibles striate 
longitudinally as in pallipes , but less regularly and dis- 
tinctly. Sculpture of dorsum of alitrunk much like that 
of the head, but the sides posteriorly are longitudinally 
striate as in pallipes ; propodeal declivity with a large 
central area devoid of transverse striae and smooth and 
shining. 
Color rather uniform medium ferrugineous. Other 
characters of structure and pilosity within the range of 
variability shown by small to medium-sized pallipes 
workers from the eastern United States. Male and fe- 
male unknown.
