Tlic Psciuloscorpions of South Africa. 117 



The specimen is of somewhat smaller size (g 2'6 mm. long) than 

 Tullgren's type (? 3'16 mm.) ; but the males of Oipium generally 

 are smaller than the females. The species seems to be recognisable, 

 among other things by having the femur of the palps somewhat 

 curved. 



35. IDEOBISIUM GODFKEYI nov. sp. 



No eyes. (Ideoblothrus.) 



Colour. Both specimens examined are very pale, especially the 

 body; the palps have somewhat more colour and are reddish. 



Cephalothorax about as long as wide, the lateral margins, which 

 are nearly straight or slightly convex, are convergent forwards 

 throughout the whole length, the front margin slightly convex, 

 with no central tooth. The surface smooth and glossy. No hairs. 



Abdomen. Tergites and sternites smooth and glossy. Some few 

 hairs left are short and pointed. 



Palps very robust, about as long as the body, with abdomen con- 

 tracted, smooth and glossy. The hairs of the inner side long and 

 pointed, those of the outer side short and pointed. Trochanter with 

 a very short stalk, about as long as wide, slightly convex in front, 

 centrally a little gibbous behind. Femur with a very short stalk, 

 robust, 2 times as long as wide, basally in front somewhat convex, 

 disdally distinctly concave, behind a little widened from the stalk, the 

 outer side nearly straight, centrally a little concave ; femur on the 

 whole slightly tapering towards the extremity, thus widest near 

 the base. Tibia with a short stalk, broadly oblong or subglobose, 

 rather equally and strongly convex on both sides, behind, however, 

 most so distally ; tibia considerably shorter and a little wider than 

 femur. Hand with a distinct stalk, and with the base nearly regular 

 and somewhat truncate ; the outer side nearly straight, except the 

 convex passage into the fingers, distinctly convex in front, passing 

 gradually into the fingers. Fingers very robust, slightly curved and 

 somewhat shorter than the hand. 



Mandibles proportionally of small size. Galea small, pointed, 

 straight, and simple. 



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

 legs broad. Claws simple. 



Length. One of the specimens with abdomen much contracted 

 is about 1 mm. long, the other specimen a little longer ; width of 

 abdomen O4 mm. 



Measurements. Cephalothorax : long. O34 ; lat. behind 0-33 ; 

 in front (viz., the length of the front margin) O21. Mandibles: 

 long. 0-14. Femur: long. O29 ; lat. at the base 0-11. Tibia: long.
