Peckliam — Spiders of the Family Aitidae. 295 



There is a band around the anterior end, a pair of spots in front 

 of the middle, a large central spot, two oblique bands on each 

 side and a pair of spots in front of the spinnerets. The legs 

 and j^alpi are brown, with a good many white, scale-like hairs. 

 The first leg in the male has, at the inner, upper part of the dis- 

 tal end of the femur, a bunch of hairs, which are black w^ith 

 white tips. Running along under all the joints of this leg are 

 two fringes of hairs of mixed colors, white, dark, and rusty- 

 brovrn, these last growing white at the ends. 



This species was described and named, some years ago, from 

 a badly rubbed female specimen. It is, in reality, very distinct, 

 the male, especially, being distinguished from all others by the 

 hairs on the cephalothorax and f alces. 



We have one male from Xorth Carolina and several females 

 from Texas.

The cephalothorax is dark brown or black, with a crescent- 

 shaped w^hite band which curves forward from the dorsal eyes. 

 There are white hairs on the sides, and between the eyes of the 

 first row. The abdomen is velvety black, with a pure white 

 band around the front end, a white, central spot, two pairs of 

 white spots further back, and two oblique lines on each side, the 

 front one running lower down than the other. Behind the cen- 

 tral white spot a bronze band runs to the spinnerets, and in 

 front of the spot there is a less distinct bronze region, which 

 sometimes appears as three indistinct spots, as is represented 

 in the figure, and sometimes consists of a central band crossed 

 by a line, the dorsum being thus broken into four black patches. 

 The legs are black, barred with reddish brown, the first one hav- 

 ing a double black fringe under the femur, and a single fringe 

 of long hairs under the other joints. This fringe is white on
