[December 
terior median eyes are one-quarter diameter apart, one and one-half 
diameters from laterals. The second tibia is thick, slightly curved, 
with macrosetae on prolateral side, but only very slightly modified. 
The palpal patella has one strong and one very weak seta. There 
are eight black, sclerotized dorsal muscle attachments on the abdo- 
men. Except for the narrower carapace, the male looks like the 
female. Total length 5 mm. Carapace 2.2 mm long, 1.6 mm wide. 
First femur, 2.2 mm; patella and tibia, 3.4 mm; metatarsus, 2.3 
mm; tarsus, 0.9 mm. Second patella and tibia, 2.9 mm; third, 1.4 
mm; fourth, 1.9 mm. 
Variation. In some individuals only four black spots remain of 
the two abdominal bands, two anterior and two posterior. If present 
the soft projection from the terminal apophysis, seen in ventral view 
(Fig. 34), may be either a flap or a rod. Females are from 4.3- 
6.5 mm in total length, carapace 1.1-1.6 mm wide; males are from 
3. 6-5. 4 mm in total length, carapace 1.2- 1.8 mm wide. 
Diagnosis. Females are distinguished from those of S. keyserlingi 
by the smaller epigynum with a lobe on each side of scape (Fig. 25), 
as opposed to a sclerotized diagonal margin seen in S. keyserlingi. 
The median apophysis of the palpus has two hooks, one on each end 
(Figs. 33, 34). In the related S. nitidula of Europe the median 
apophysis is of different shape and the embolus narrower. 
Natural 'History. Wisconsin specimens came from open bottom- 
land forest, along backwaters of river edges, and edge of marsh ; 
Georgia specimens came from Spartina stems. Barrows (1918, 
Ohio J. Sci., 18: 310) reported that a Singa from Cedar Point, 
Ohio, almost certainly this species, made “a small orb in tops of 
dune grass (Andropogon) . During the day it stays in the hollow 
stems of dead grass.” The spiders have also been collected in Penn- 
sylvania by the wasp Episyron quinquenotatus (Say). The males 
are mature in September and October in the north. Adult females 
have been collected from May to October.
