and scattered, pointed, those of the inner side long and strong, those 

 of the outer side very short and more slender. Trochanter with a 

 short stalk, and very short, of the shape usual in Chthonius, slightly 

 convex in front, a little concave behind. Femur long and slender, 5 

 times as long as wide, nearly parallel-sided, except in the distal third 

 which is somewhat widened on both sides, thus on the whole some- 

 what club-shaped ; the inner side at the stalk as usual with a sinuation. 

 Tibia very short and of the usual shape. Hand scarcely pedicellate, 

 very short and broad, with the base obliquely rounded, the outer side 

 slightly convex, the inner side somewhat more strongly so, slantingly 

 passing into the fingers. Fingers very slender, seen from above 

 nearly straight, a little more than twice as long as the hand ; seen 

 laterally the fingers are strongly curved, the movable finger regularly 

 curved throughout its whole length, most strongly so at the tip ; the 

 fixed finger is doubly curved like - ^.^ ; the fixed finger distinctly 

 longer than the movable one; the fixed finger has long, narrow, 

 pointed teeth with great interstices, centrally the teeth are longest 

 and have the largest interstices, basally and apically the teeth are 

 lower and placed more closely. The i)irl>/<' finger is practically 

 destitute of teeth ; the margin is, however, not quite entire, but has 

 some very low traces of teeth. 



Mandibles large and robust, shagreened ; the fixed finger provided 

 with 5 to 6 teeth, the central ones the largest, decreasing in size 

 backwards ; the movable finger with 8 to 9 very small teeth in the 

 distal half. On the outer side of the movable finger there is generally 

 the usual projection. 



Legs. The two posterior pairs of legs very robust, particularly the 

 femora. Claws simple.

NOTE. This species is related to Chthonins contractus Tullgren, 

 with, for instance, the same shape of cephalothorax, but differs from 

 it in several characters : The fingers of the palps, which are curved 

 and not of equal length ; the movable finger nearly completely lack- 

 ing teeth (Tullgren, as to ClitJiouius contract us, in this respect refers 

 to Chthonius terribilis With, which has distinct teeth on both fingers), 

 more precipitous passage from the hand to the fingers ; finally, the
