Length, 2.5 mm. Legs, $ 1432, $ 4132, first pair a little 
the stoutest, spines very long, three pairs under the first tibia, 
two serially under the second tibia, and two pairs under the first 
and second metatarsi. 
The male cephalothorax is brown, darkening toward the front 
end. In the female there is a black band across the front and 
running back on the sides of the eye-region, while the rest of the 
cephalic plate is white except for two short dark lines which end 
in small black spots, in front of the middle. The thoracic part 
is brown. The abdomen has a pale ground covered with brown 
mottlings, which form a herring-bone stripe down the middle. 
The legs are brown except the proximal joints of the posterior 
three pairs, which are pale. They are marked with darker lines 
and spots, and the first pair is much the darkest. The palpi and 
underparts are pale in the female, dark brown, sometimes black, 
in the male. 
Mr. Banks has this species from Long Island, 1ST. Y., and he 
also describes it under the name Icius obliquus, from Olympia, 
Washington. We have it from the Canadian Rockies and from 
Pennsylvania, and Mr. Emerton says that it is common in Yew 
England. He also reports it from near Ottawa, Canada.
