with five external teeth; intermediate and posterior tibiae with 
distal spurs prominent, the outer spur longer than the inner 
one; intermediate tibiae with two, posterior with three external 
spines. Female unknown, but as characteristic to the genus, 
may resemble the male very closely in habitus, with slightly 
modified mandibles. Dimensions; Length (excl. mandib.) 18.5 
mm.; mandibles (minus apices) 1.75 mm. 
Head 6.5 mm. wide; 3.25 mm. long 
Prothorax .... 7.0 mm. wide; 5.25 mm. long 
Elytra 7.25 mm. wide; 10.0 mm. long 
Holotype: S , West Africa, Coll. Harvard, in the Museum of 
Comparative Zoology, Cambridge, Mass.; type No. 25,913. 
Superficially resembling the Australian Figulus trilobus 
Westw., 4 assigned, subsequently, by Parry 5 to Nigidius ; it 
differs, however, from F. trilobus by the broader head (in 
trilobus more triangular in outline), mandibles, cylindrical 
body ( trilobus depressed), scutellum ( trilobus wedge-shaped), 
etc.; it can be mentioned here that F. trilobus Westw. is a true 
Figulus , and not a Nigidius , as Parry suggested.
