somewhat from the base, and a minute denticle at the terminal 

 margin. Tarsal claw simple. 



Legs of middle length. First coxae with a considerably num- 

 ber of granules, each with a short, black seta; the other coxae 

 with the granules and setae more feebly developed. First pair 

 of legs with femur, patella and tibia considerably thicker than 

 in third or fourth pair, and much thicker than in second pair. 

 Femora of first pair only a little shorter than the body, conspi- 

 cuously clavate (fig. 2 d) and somewhat curved, with longitu- 

 dinal rows of well developed, triangular denticles and a number 

 of scattered denticles, but without any process at the end. Se- 

 cond femora considerably longer than the body; the three po- 

 sterior pairs of femora with rows of denticles distinctly smaller 

 than those on first pair. Patellae and tibiae of all legs with the 

 denticles conspicuously smaller than those on the respective 

 femora and partly rudimentary; tibiae more or less subangular. 



Colour of the body yellowish-grey, with some dark spots 

 above; palps light yellow, but their femora, excepting at the 

 end, the proximal part of tibiae and the end of the tarsi dark. 

 Legs in the main as the palps, with the distal part of the femora 

 and patellae brownish, while the subdistal part of the tibiae 

 is only slightly darker than the proximal part. 



Length of the body 5.6 mm.,' first legs (without coxae) 20 

 mm., second legs 34.5 mm. 



Remarks. This new species is more related to Dacno- 

 pilio Roewer than to any other genus. Roewer has described 

 two species, which differ much from one another in armature 

 and probably also in size of the mandibles in the male, and the 

 new species seems in some features to be intermediate between 

 the two other African forms. 



Occurrence. The single specimen, an adult male, was 

 taken in February 1902 in 1300 1400 m. above the level of 

 the sea at Moka on the Island of Fernando Poo.
