DESCRIPTIONS OF NEW OR LITTLE KNOWN 
SPIDERS OF THE FAMILY ATTULE, FROM 
VARIOUS PARTS OF THE UNITED STATES 
OF NORTH AMERICA. 
WITH THREE PLATES. 
By G. W. and E. G. Peckham. 
In describing the following spiders we have used but three generic names; not 
because we consider all these species as properly belonging together, but inasmuch as 
we are now engaged in preparing a monograph of this family, we judge it best to defer 
any discussion of its classification until later. Meanwhile we shall hope to prepare 
the way for this discussion by shortly publishing a synopsis of the various genera thus 
far formed. Although we have many Attidae from different parts of the world, we shall 
feel greatly obliged to any arachnologists who will aid us in ourdilllcult undertaking by 
sending us collections of Attidae. For all such collections we will gladly send, in 
return, spiders of the United States. 
We are indebted to Mr. Rudolph Haessler for the drawings, which were made from 
nature. 
Milwaukee, Wis., October 10th, 1883. 
I. Arras ruTNAMii, new. 
(Plate I, Figures 1 to lb.) 
MALE— Length, 0 mm.; width of abdomen, 2.6 mm. ; length of ceph.th. 4.5 mm.; width 
of ceph.th , 3.3 mm. 
The cephalothorax is hijjh, highest and widest at the dorsal eyes, 
the thoracic part being longer than the cephalic. The color is reddish 
brown; there is a large white spot just behind the dorsal eyes, and 
a short white band on each side of the eye-region extending from the 
small median to the dorsal eye. Just back of the small median eye is 
a tuft of black hairs. There are thick, light brownish hairs above the 
anterior row of eyes. 
The quadrangle of the eyes is wider than long, and much wider 
behind. The dorsal eye is about as large as the lateral eye, and is 
placed higher, so that a straight line from its lower border cuts the 
upper border of the lateral eye. The small median eye is in a line 
with the dorsal eye, but is further from the dorsal than from the lat- 
eral eye. The anterior row of eyes is very slightly curved, a straight 
line from the top of the middle eyes cutting the upper borders of the ■ 
lateral eves. The lateral arc well separated from the middle eyes ; 
the middle eyes touch each other. The middle arc not quite twice as
