Ch. Canestrinü: Coxa entirely smooth and glossy, as also great 

 part of the hand below, tibia shorter and rather more regular, femur 

 3 — 4 times as long as broad, hand about as long as tibia, fingers a little 

 shorter or even considerably shorter than hand, the hairs of abdomen 

 slightly davate. 



Ch. proxinms: Coxa smooth and glossy except the front part, tibia 

 about alike that of ruf us, but a little more regular, femur similar to 

 that of rufus, hand distinctly shorter than tibia, fingers distinctly longer 

 than hand, about 1: 1,25; the hairs of abdomen rather long and slender, 

 but slightly davate. 



Genus : Ideohisiiim, 



Subgenus: Ideoroncus. 



Ideohisiiim chilense nov. sp. 



One small eye on each side, about 2 diameters from the front 

 margin. 



Palps, céphalothorax and sclerites jmle reddish, the other parts 

 greyish white. 



Céphalothorax much longer than broad, nearly paralldsided , the 

 anterior Y4, however, somewhat roundly narrowing forwards, front 

 margin distinctly sloping from the middle towards the sides (about as 

 in 2Iicrocreagris gigas Balzan , but not «piite so much) , in the middle 

 no point; minutely striped- shagreened, glossy, with some few simple, 

 obtuse hairs. 



Abdomen: tergites and sternites shagreened and glossy; there is a 

 tending to a fine longitudinal stripe on some of the tergites, at all events 

 the colour of the tergites is discontinued in the middle, on account of 

 w^hich a light, rather broad, longitudinal colour band is seen ; somewhat 

 before the hinder margins of the somites there are or have been some 

 few, rather long, pointed hairs. 



Palps longer than the body, but abdomen is somewhat contracted, 

 glossy; coxa and trochanter minutely granulated, femur more distinctly 

 granulated, except on the outer side, this being shagreened, tibia granu- 

 lated on the inner side, the rest shagreened, hand minutely shagreened 

 on the inner side, the rest smooth, the fingers smooth. The hairs pointed, 

 somewhat longer on the inner side than on the outer one. — Trochanter 

 stalked, a little longer than broad, the inner side somewhat convex, at 

 the extremity with a strongly swelled, semicircular ring (as in Ideobisiimi 

 imllidiim Balzan), the outer side strongly concave, in all calyciformed. 

 Femur a little longer than céphalothorax, with a short, but robust stalk, 

 in the central part strongly curved upwards and forwards, the inner side 

 somewhat convex, towards the extremity a little concave, the outer 

 side in the greater part slightly concave, towards the extremity a little 

 convex. Tibia with a long stalk, a little shorter than femur, somewhat 

 club-shaped (as in Id. pallidmn), the outer side very slightly and regu- 

 larly convex, the inner side somewhat more strongly so in the middle.
