anus, and a less distinct, pale, unequal, violet band along each side. 

 The vulva is placed in a pale brown spot, and is itself pale brown, with 

 the lateral costse blackish. The mamilUe are pale greenish-yellow; the 

 upper pair violet above. The fine hair with which the body and ex- 

 tremities are covered is whitish; the thighs are sprinkled with black 

 hairs ; the spines are black. 



Length of body 6, of cephalothorax 2 millim. ; breadth of cephalo- 

 thorax 21 millim.; length of abdomen 4, breadth of same 3J millim. 

 Length of legs: I 8J, IL 10, III nearly 7^, IV 7^ millim.; pat. + tibia 

 I 3, II 3^, IV 2^ millim. 



The only example in the collection, a female, was captured at Golden, 

 Colo., July 3.

Cephalothorax dark l>rown, with a longitudinal short and rather nar- 

 row, pale middle band behind ; the eye-rows very slightly curved, the 

 lateral eyes of each row little, if at all, larger than the centrals of the 

 row; area of the central eyes slightly broader than long, broader be- 

 hind than in front; interval between the lateral and the central eyes of 

 the same row much smaller than that between the centrals ; legs dark 

 brown, with pale irregular rings; back of abdomen pale grayish-white 

 in front, with a lanceolate black band along the middle of this grayish- 

 white area, which is continued backward as a tapering grayish- white 

 band, on the sides of which the back is dark brown, mottled with black 

 and white; vulva consisting of a small, semicircular, pale brown de- 

 pression, with two short, longitudinal, parallel, black costse behind. — 9 

 ad. Length about 6 millim. 



Female. — Cephalothorax little longer than broad, as long as tibia of 

 the fourth pair, very strongly rounded in the sides, strongly sinuated and 

 narrowed just in front of the coxae of the first pair, rather thickly cov- 

 ered with coarse api^ressed hair ; the pars cephalica narrowing forward, 

 slightly rounded in front, the breadth of the clypeus not equaling half 

 that of the pars thoracica ; seen in profile, the back is nearly straight 

 from the rather short posterior declivity to the eyes, slightly sloping 

 between the eyes, the clypeus more abruptly sloping, with a transversal 

 depression just under the ej^es; its height is evidently greater than the 

 length of the area occupied by the central eyes. The cephalic furrows 

 and the hind central furrow are very distinct. Both the front and 

 the hind row of e^es but very slightly curved backward (upward); the 

 eyes of the front row appear to be a little larger than those of the hind row, 

 and to be of equal size, the central ones at least not larger than the 

 laterals ; the hind laterals are perhaps slightly larger than the hind 

 centrals. The area occupied by the central eyes is very nearly as long 

 as broad behind, broader behind than in front ; the interval between 

 the fore lateral and central eyes is nearly double as small as that 

 between these latter, which are separated by an interval about half
