with sparse, moderately long, thin, reclinate hairs. Petiole, 
postpetiole and gaster with sparse, long, thin, curved, erect 
hairs. Legs with thin, moderately long, reclinate hairs. 
Spongiform processes approximately as in S. pulchella. 
Color ferrugineus ; gaster darker. 
Type locality: Kitts Hill, southern Lawrence County, 
Ohio. 
Similar to S. pulchella Emery and S. creightoni M. R. 
Smith. From S. pulchella , S. venatrix differs in (1) the 
narrower anterior portion of the head, and correspondingly 
a proportionately wider posterior portion; (2) the differ- 
ently shaped clypeus; (3) the longer mandibles; (4) the 
different pilosity, particularly on the head. From S. creigh- 
toni, which it closely resembles in the shape of the head and 
mandibles, S. venatrix differs in (1) its entire and rounded 
clypeal borders; (2) the very different pilosity, especially 
on the vertex of the head and on the thorax. 
Described from a colony containing about 60 workers. 
Eight colonies and occasional scattered workers have 
been taken in Pike, Lawrence, Scioto and Adams Counties. 
The species is definitely a soil or humus dweller and forages 
for Collembola under the leaves and dead vegetable matter 
on the surface of the ground. So far as we can tell, it is not 
associated with other species for the purpose of obtaining 
the Collembola about their nest. Specific examples of the 
colonies may give a better idea of the habitus. A colony 
was found in a small opening near the edge of some young 
oak woods on a rather dry, gently-sloping hillside. The soil 
was a sandy clay. Several workers were first observed 
around a light cover of dead leaves. One of these, carrying 
a springtail in its mandibles, led to the nest, the entrance of 
which, was a tiny hole under a flake of stone in the middle of 
a small bare area 30 sq. cm. in extent. Just below the sur- 
face, this hole widened out into a spacious, elongate chamber 
5 to 10 mm. in diameter and 10 cm. in length, which ap- 
peared to be the hollow interior of a dead and decayed root. 
Another colony was found in the grassy humus on the edge 
of a bushy thicket in a field. A colony of Aphaenogaster 
fulva was under an adjacent stone. Four colonies, including 
the type, were found in a grassy clearing in some dry, open 
woods. Two of these colonies were on the surface in the
