Coloration, i . Cepbalo thorax liglit brown; a band of white hairs comes 

 up from between the middle anterior eyes and joins a white spot 

 which is found on the posterior cephaHc part; on each upper side is 

 a wide band of white hairs which extends from the anterior lateral 

 eye, surrounding the dorsal eye, to the posterior margin; there is a 

 white line around the lower margin; the entire face is covered with 

 thick snowy white hairs, which grow from the sides toward the m.id- 

 dle, surrounding the anterior eyes and growing downward on to the 

 upper part of the falces; just behind and below the anterior lateral 

 eyes are some small scattering tufts of black hairs. Abdomen light 

 golden brown, encircled by a wide band of white hairs. Falces (ex- 

 cepting the white hairs at the upper edge) and mouthj)arts dark red- 

 dish brown. Sternum, coxse and venter light brown. Legs all light 

 brown excepting the last three joints of the first pair which are dark 

 reddish . brown; all the legs tipped with black, g , Cephalo- 

 thoras light brown covered with short white hairs, which are easily 

 rubbed off, but usually show a white band coming up from between the 

 -middle anterior eyes. Abdomen covered with gray hairs and fine 

 red dots. Venter covered with gray hairs. Mouthparts pale. Legs 

 pale (excepting first pair which is light brown) all tipped with black. 

 Face and other parts as in male. In some cases the male retains the 

 coloration of the female. 



This species bears a strong general resemblance to Icius albo-vittatus Keys. 



Habitat: California.

Cephalothorax rather lo^v and nearly fiat, contracted slightly in front and 

 behind, one-fourth longer than wide, and a very little wider than the 

 third row of eyes. Cephahc part occupies two-fifths of the cephalo- 

 thorax; the thoracic part begins to slant near its posterior border, and 

 is rounded behind. Quadrangle of eyes nearly twice as wide as long, 

 and equally wide in front and behind. First row of eyes nearly 

 straight, m.iddle very nearly touching, and three times as large as 

 the lateral, from which they are just sej)arated. Second row of eyes 

 small and plainly nearer (two-fifths) the anterior lateral. Dorsal eyes 

 as large as lateral, and much further from each other than from the 

 lateral borders. Clypeus very low (one-fifth to one-eighth the height 

 of anterior middle eyes). Sternum oval, a httle longer than wide, 

 projecting between the coxse of the first pair, which are separated by 

 the width of the labium. Labium less than half as long as the max- 

 illae, and as wide as long. Falces short (as long as the face) but little 

 longer than wide. Legs 1, 4, 2, 3. First stoutest, second next. The 

 patella with tibia of the third shorter than patella with tibia of the
