Notes on Strumigenys 
103 
with long thin erect hairs, slightly enlarged apically. Legs 
and antennal funiculi with thin reclinate hairs. Spongi- 
form processes as in S. pulchella. 
Color ferrugineus ; the gaster, darker. 
Type locality: Jackson, Ohio. 
We have compared S. reflexa with cotypes of S. missouri- 
ensis M. R. Smith and S. sculpturata M. R. Smith to both of 
which it is very similar. From S. missouriensis it may be 
distinguished by (1) the broad depression on the anterior 
portion of the head; (2) the much more strongly scalloped 
and sculptured head; (3) the less convex mandibles; (4) 
character of the pilosity. From S. sculpturata it differs in 
(1) the more robust head; (2) the rounded, non-truncate 
clypeus; (3) the slightly less abundant pilosity, particularly 
on the clypeus and gaster; (4) the appearance of the 6 large 
fringing clypeal hairs which are curved strongly backward 
— a feature by which this form may be easily recognized- 
A colony of this species was found in a small, punky, 
partly-buried board in moderate shade in a backyard in 
Jackson. The colony was within a meter of a large log pile, 
and workers were found foraging among the woody debris 
at the base. Stray workers were discovered at 2 other places 
in the yard. An early attempt to find the above colony gives 
a check on the feeding habits of the species. A dead spring- 
tail was placed in front of a worker which had been dis- 
covered beneath a piece of bark. Apparently not greatly 
disturbed, the ant continued to stalk among the debris 
until she came within about 1 mm. of the springtail. She 
then crouched and waited. After several minutes, the 
springtail was gently pushed toward the ant until it was 
partly on top of her head. The next instant the ant was to 
be seen holding the already dead springtail tightly in her 
mandibles and stinging it viciously. In a few seconds she 
started off at a rapid pace with the springtail. In the arti- 
ficial nest the hunting methods of the workers were similar 
to those of S. pulchella , but even more sluggish.
