Occurrence. — The material, consisting of 3 adult males, 

 I adult female and an immature specimen, was taken at Musola, 

 Island of P'ernando Poo, January 1902, in an altitude of 400 — 

 500 m. 



Parogovia n. gen. 



Cephalothorax anteriorly produced into a triangular plate 

 (fig. 2 a), which covers at least the inner part of the transverse 

 keel on first joint of the antennae. A median keel on cephalo- 

 thorax is not developed. 



Eighth and ninth abdominal sternites completeh^ fused, 

 and besides fused with the ninth tergite so that not even a 

 vestige of any furrow between these plates is seen (fig. 2 b) . 



No eyes. 



"Coni foetidi" moderately long, seen from above nearly 

 obUquely triangular, directed outwards and feebly upwards, 

 and about half as long from the lower margin of the cephalo- 

 thorax as the length of the basal diameter of the cone. The 

 end of each cone has a ver}' oblong and ^'ery convex, smooth 

 and shining area or piece, which looks almost as a single mode- 

 rately thick lobe. 



First joint of the antenna" (fig. 2 e) not reaching to the end 

 of the fenmr of the jjalps, considerably compressed, on the lower 

 side raised as a large, rounded tubercle, and above with the 

 proximal transverse keel well developed. The teeth on the mov- 

 able finger subsimilar in shape, moderately high, rounded; 

 on the fixed finger two kinds of teeth alternate (fig. 2 g), half 

 of them being larger than on the movable finger, moderately 

 high and rounded, while each interval between two such teeth 

 is occupied with an extremely low but somewhat broad tooth, 

 with the free margin a httle convex. 



The palps (fig. 2 h) have the trochanter proximally slender, 

 distally much thickened with some granules, somewliat shorter
