Peckham—Revision of the Attidce of North America. 563 
The middle of the back of the abdomen, is also yellow, mixed 
with yellow hairs. 
Mr. Emerton, from whom we have taken the description given 
above, has several specimens from Laggan, Alberta. We have 
only females. They are marked like Mr. Emerton’s specimens 
but are colored differently. In one from Laggan the spaces on 
the back of the abdomen between the central black-bordered 
white band and the oblique black and white bands on the sides, 
are filled in with hairs of a bright coppery-pink color, which 
also cover the clypeus. In a female from Denver, not only is 
the ground color pink but the white bands are strongly tinged 
with the same color. The legs are dark, contrasting with the 
palpi, which are of a very light brown. The falces are black. 
A young female has the upper surface of both cephalothorax and 
abdomen pink, the pattern being in a lighter shade. 
Montanus comes from Laggan, and from Denver, Colorado.

9 . Length 6.2 mm. Legs 3412, first pair stoutest. 
Under alcohol the cephalothorax is dark with four oblique 
white bands on the cephalic plate, and the abdomen and legs are 
light brown mottled with dark brown. When dry the white 
bands on the eye-region become more distinct, one on each side 
and two in the middle, which start from one point between the 
front eyes, and diverge so that their ends touch the dorsal eyes. 
The spaces between are filled with fawn-colored hairs. Whitish 
bands pass back from the dorsal eyes and encircle the lower sides, 
the upper sides and middle thoracic part being covered with 
dark, yellowish-brown hairs. The clypeus is white with two ob¬ 
lique dark bars which run outward from under the middle eyes. 
The abdomen is light fawn with dark mottlings, and shows an 
indistinct band of chevrons down the middle. 
One female in the Cambridge Museum Collection, taken by 
Mr. Henshaw at The Dalles, Oregon.
