8. — IdeoMsium tacomense nov. sp. 



ISÌ0 eyes, but the animal is in the general appearance more 

 like an Ideoroncus than an Ideoblolhrus. 



Colour. Cephalothorax and palps reddish brown abdomen and 

 the other parts greyish brown. 



Cephalothorax considerably longer than wide, parallel-sided, 

 only a little contracted in front, the front margin slightly con- 

 vex, with no tooth in the middle. The surface smooth and glos- 

 sy, provided with some scattered, common hairs along the sides. 



Abdomen glossy, the skin provided with fine stripes forming 

 polygons, with rather long, acute hairs; one « tactile » hair left 

 on the last segment 



Palps about as long as the body, rather robust, glossy. Coxa 

 completely smooth; trochanter smooth below, the upper surface 

 somewhat rough, but not granulated; femur strongly granulated 

 round about, less strongly below; tibia and hand slightly granu- 

 lated, less so on the lower side. The hairs of the palps long and 

 fine, acute; the fingers with « tactile » hairs. — Trochanter rather 

 long, nearly twice as long as wide, the inner side slightly con- 

 vex, the outer side nearly straight. Femur with a short and in- 

 distinct stalk, this excepted nearly parallel-sided, the outer side 

 slightly convex near the base and the extremity, in the central 

 part nearly straight, the inner side nearly straight; femur in all 

 scarcely narrowed at the extremity. Tibia with a long and cur- 

 ved stalk, elongate, a little wider than femur, the outer side sli- 

 ghtly convex, most so in the distal half, the inner side somewhat 

 more strongly and regularly convex: tibia in all only a little 

 narrowing at the extremity. Hand with a rather long stalk, with 

 regularly rounded base, the outer side slightly convex, the inner 

 side somewhat more strongly so, tapering to the fingers. 



Fingers robust, rather strongly curved, about as long as the 

 hand, the inner margins provided with a dense row of truncated 

 teeth.
