pale yellow and gray. The cephalothorax is dark in the middle 
and light at the sides, with light gray spots over the coxe. The 
dark middle area extends forward between the eyes to the front 
edge of the head, dividing into two below the eyes. The mandibles 
are striped on the front with black. The abdomen is light at the 
sides, and the middle dark marks are united into a broad stripe 
with irregularly indented edges. The legs are marked with broken 
dark rings, the femur and the tibia having parts of four rings each. 
The sternum is dark around the edges, and the whole under side 
of the abdomen is gray, darkest at the sides, with two indistinct 
light lines converging toward the spinnerets. The tibia of the male 
palpus is as short as the patella. The process of the tibia is as 
long as the diameter of the joint. It is flat and widened at the 
end, hollowed in at the middle, and with the corners sharp, and 
sometimes two little teeth in the hollow. The palpal organ resem- 
bles that of the other species. 
A female just moulted, from Three Mile Island, Lake Winni- 
pesaukee, N. H., May 25, 1905. Cephalothorax 6.5 mm. and abdomen 
the same length; fourth and first legs 24 mm. Colors and markings 
like those of male. The epigynum resembles that of D. doneus 
with the middle portion not as prominent, and the pockets at the 
sides more open. 
At Three Mile Island, between May 20 and 27, 1905, one female 
and several males made their last moult. They were under stones 
and loose boards lying on the ground near the shore. 
Oxyopes scalaris (Hentz) Em. 
This species was found again at Durham, N. H., in June 1904. It 
resembles closely a species found commonly on the Pacific Coast 
from British Columbia to California.

2.5 mm. long, pale and translucent, with black spots on the head 
and legs and around the sides of cephalothorax and abdomen. The 
cephalothorax is as wide as long, and almost circular. The eyes 
are on the top of the head in two nearly straight rows, the front 
row shorter than the upper, and the front middle eyes farther apart 
than they are from the lateral eyes. The upper middle eyes are 
not round but irregularly oval, largest from front to back. The 
head extends forward a little beyond the eyes, and under this
