over. The sternum is also rough. It extends backward between 
the fourth legs, where it is wider than the coxe. It extends also 
between the first and second, and between the second and third 
legs. The maxille are wider than long, and the mandibles stout, 
with four teeth on the front of the claw, and three small and one 
large one on the inner side. The eyes spread across the whole 
front of the head. The front row is straight, with the middle pair 
smallest, and the middle quadrangle is higher than wide. The ab- 
domen is round and a little pointed at the spinnerets as in Erigone. 
The abdomen is covered with short and fine scattered hairs. The 
coxe are long, extending beyond the border of cephalothorax, so 
that all are visible from above, and the legs are long and _ stout 
and covered with coarse hairs. 
The epigynum is very far forward and has a light colored middle 
lobe, longer than wide, at the sides of which the spermathece show 
through the skin. 
The palpal organs are very simple; the tube and two short ap- 
pendages showing only at the distal end. The tarsal hook is small 
and the tarsus short and round. The tibia is widened a little across 
the middle, and has a flat extension with a straight edge against 
the upper side of the tarsus. 
The relations of this species are doubtful as the male does not 
have the grooves and pits in the sides of the head which are char- 
acteristic of the males of most species of this genus. In other 
respects, however, its resemblance is close to L. /atum and L. cre- 
natum and still more to an undescribed species from Long Island, 
N. Y., for which the females are easily mistaken. The sternum in 
all of these is wide and convex and roughened all over the sur- 
face. The extension between the legs occurs in the same way in 
L. crenatum. The form of the epigynum is the same in all four 
species. The resemblance of the male palpi is equally close, all 
the species having the tarsus nearly of the same shape and the 
parts of the palpal organ small and with only slight variations 
among the species.

This species has been found again in March, 1907, under leaves 
in Allston, near Boston. The male and female are of the same size 
and much alike. They are pale in color, the legs and cephalo-
