Female: Carapace, sternum brown; legs lighter brown. Abdomen brownish white, sometimes with dusky ring around spinnerets and a dusky patch on each side of abdomen dorsum. Carapace, sternum heavily sclerotized, massive. Anterior median eyes smaller than others, one. diameter apart, one-quarter diameter from laterals. Posterior medians one. and one-third diameters apart, two-thirds diameter from laterals. Epigynum a heavily sclerotized plate with two dark spots side by. side (Fig. 25). Total length, 1.3-1.6 mm. A female from Wisconsin measured: total length, 1.6 mm.; carapace, 0.70 mm. long, 0.62 mm. wide; first patella and tibia, 0.59 mm; second, 0.55 mm.; third, 0.47 mm.; fourth femur, 0.58 mm.; patella and tibia, 0.65 mm.; meta¬ tarsus, 0.35 mm.; tarsus’ 0.35 mm. long.

Male: Ventral scutum illustrated by figure 27, palpus by figures 19, 20 and 21. Total length, 1.3-1.6 mm. Measurements of a specimen from Wisconsin: total length, 1.4 mm.; carapace, 0.71 mm. long, 0.65 mm. wide, 0.45 mm. high; first femur, 0.71 mm. long; patella and tibia, 0.75 mm. long; metatarsus, 0.39 mm. long; tarsus’ 0.39 mm. long; second patella and tibia, 0.67 mm. long; third, 0.52 mm. long; fourth, 0.72 mm. long.

The largest specimens examined all came from northern localities, the smallest from the south. Southern specimens more commonly have dusky patches on abdomen than do northern ones.

In Wisconsin this species is found only in leaf litter of climax maple and basswood forests. Wherever it occurs, it is very abundant. In other areas it apparently has been collected also from litter of climax maple and beech forests.

Type locality: Syntypes from Mt. Carmel, Hamden, Connecticut, in the Museum of Comparative Zoology .
