A REVISION OF THE PISAURIDAE OF THE UNITED STATES A3 
hard ground. An immature male was found in May at Thacher 
Park, Albany county, halfway up a dry hillside on a log. Since 
immature specimens of all sizes have been found late in the fall, it 
is evident that neither this species or D. scriptus matures in 
one season; in fact immature specimens have been found in hiber- 
nation in November at Ithaca, N. Y. ‘The species in the north is 
not common compared with D. scriptus but farther south, in 
Virginia and Maryland they occur in great abundance. 
Various species of this genus have been recorded as capturing 
and feeding on fishes. McCook (v. I, p. 235) mentions a case in 
which a fish three and one-fourth inches long was captured and drawn 
from the water by a spider only three-fourths of an inch in length. 
More recently, Thomas Barbour has recorded the capture of small 
Cyprinodonts by spiders identified as Dolomedes tene- 
brosus (Psyche, 1921, 28:131-132).
