Convex, in the distai lialf very slightly concave, or the whole inner 

 side nearly straight, behind fronti the stalk gradually increasing in 

 width, the outer side nearly straight or even a little concave in the 

 middle. Tibia with a long stalk, distinctty shorter than femur and 

 a little broader, the stalk excepted somewhat longer than broad, the 

 outer side regularly and strongly convex, the inner side somewhat 

 swollen and convex near the base, towards the extremity somewhat 

 attenuated, sometimes rather concave, the upper surface flatteued, 

 below strongly convex. Hand with a distinct stalk, from rounded base 

 on the outer side moderately convex, on the inner side more strongly 

 so. Fingers distinctly longer than hand, but somewhat differing in 

 this respect in the dilferent specimens, rather robust, distinctly curved, 

 on the inner margins with numerous, minute teeth, sitting dose to- 

 gether, on the fìxed finger obliquely triangular, on the moveable oue 

 truncated. 



Mandibles: the moveable finger nearly twice as long as the trunk, 

 measured laterally, with a very little conspicuous protuberance at 

 the rounding of the point. 



Legs with pointed hairs. The femora of the two posterior pairs 

 of legs, especially those of the last pair, much broader than those of 

 the two anterior ones. Coxa of the first pair with a distinct, brown 

 point at the outer corner. Claws simple. 



Length e a. 3,5 nini. 



Measurements: Cephalothorax: long. 0,76; lat. 0,65. Femur: long. 

 0,79; lat. 0,24. Tibia: long, 0,07 (thereof the stalk 0,12); lat. 0,31. 

 Hand: long. 0,03; lat. 0,47. Fingers: long. 0,74 min. One of the femora 

 of the last pair of legs: long. 0,72; lat. 0,27 nini. 



Italy: Colle delle Finestre 15 specimens; Boves 1 specimen. France: 

 Vernet-les-Bains 17 specimens (Dr. A. Borelli). 



The specimens from Vernet-les-Bains are very small, the tooth of 

 the front margin of cephalothorax very minute, sometimes absent, the 

 granulation of femur less strong and, particularly on the upper sur- 

 face, less dense than in the animals from Italy. 



Subgenus: Blothrus, no eyes.

 No eyes. 



Colour: the whole animai pale yellowish.
