Cephalotliorax liigli, especially behind, convex, a little dilated in the mid- 

 dle, with sides vertical in front and a little rounded behind; cephalic 

 part plainly inclined; thoracic part slanting quite abruptly from a 

 little behind dorsal eyes, the cephalotliorax being evidently highest 

 in the middle. Ocular area occupying a little more than one-third 

 of cephalotliorax, one-third wider than long, a little wider in fi'ont 

 than behind. First row of eyes straight; middle eyes touching, lat- 

 eral more than one-half as large as middle eyes, (?) touching them, 

 ( 3 ) separated from them by one-fourth their own diameter; eyes of 

 second row half way between dorsal and lateral eyes; dorsal as large 

 as lateral eyes, ( S ) equally distant from each other and lateral bor- 

 ders, (?) a little nearer each other. Clyj)eus ( 8 ) one-fourth, (?) one- 

 fifth as high as middle eyes, ( ^ ) retreating, (?) vertical. Falces as 

 wide as the two middle eyes, ( ^ ) a little longer than face, ( ? )as long 

 as face, parallel, inchned backward; fang weak, maxillae parallel, nar- 

 row at base, enlarged at extremity, and truncated. Labium as wide 

 as long, less than one-half as long as maxillee, contracted at tip. Ster- 

 num nearly twice as long as wide, rounded in front, pointed behind. 

 Anterior coxge separated (?) by width of labium, {$) more widely. 

 Legs ( ,5 ) of the first very slightly stouter than the others, (?) equally 

 stout; femoral, tibial and metatarsal spines on the four pairs; ( ^ ) 

 with patellary spines; metatarsi of the fourth spined throughout 

 their length. 



Coloration: $ . Cephalotliorax pale in thoracic part, much darker in eye 

 region, probably originally covered with short "white hairs; marginal 

 line black ; middle anterior eyes surrounded by rings of white hairs. 

 Clypeus reddish brown. Abdomen with a black central longitudinal 

 line over the anterior part of the dorsum, which bifurcates posteriorly, 

 thus bounding a large triangular pale spot; this sjDot is limited beliind 

 by some irregular black marks; the sides are pale with black dots and 

 spots. Falces, mouthparts, sternura and coxae all light brown. Ven- 

 ter iiale with black dots. Legs brown with black rings and tii^s, the 

 color being considerably darker on the last three joints of the first 

 leg. ? . Cephalotliorax and abdomen black, almost covered with 

 mixed red and gray hairs; on the abdomen these hairs are thick at 

 the base, and form three wide longitudinal bands, one central and two 

 lateral, over the dorsum, and a large trirngular spot beliind the mid- 

 dle point; near the apex, on each side, are two white dots, the ante- 

 rior larger and a little external to the jposterior. Clypevis covered with 

 short white hairs. Falces dark brown. Mouthparts, sternum and 

 cox£e light brown. Legs and palpi brown with darker rings. Venter 

 pale with irregular black dots. 



Habitat: California.
