Titanodamon tibialis (Simon). 



Phrynus tibialis, Simon, Bull. Soc. Zool. Fr. 1876, p. 12. 



We have two examples that I refer to this species — one 

 ticketed Congo, the other West Africa. They were identi- 

 fied by Mr. Butler as bassamensis of Lucas ; but, judging 

 from the locality, it seems to me more probable that they are 

 to be referred to tibialis, the type of which also came from 

 the Congo. 



Titanodamon Johnstonii, sp. n. (PI. VIII. figs. 2-2 b.) 



Colour nearly black, with two whitish patches on the 

 femora and indications of spots of the same colour upon the 

 muscular impressions of the terga and upon the posterior 

 angles of these plates. 



Carapace thickly granular, the lateral margin spicular, the 

 front margin also slightly spicular ; distance between the 

 lateral eyes a little greater than half the median length of 

 the carapace and three times as great as the distance between 

 either of the lateral tubercles and the nearest point of the 

 anterior border. Median tubercle smooth, shining, on the 

 anterior border, the frontal process conspicuous, directed 

 downwards and forwards and ending in a bluntly rounded 

 apex. 



Mandibles granular above, with two enlarged distal 

 tubercles. 



Chelce. — Coxa granular distally ; trochanter armed with 

 an upper ridge of spinules, one longer inferior spine, and a 

 number of shorter spines of varying lengths ; femur granular 

 throughout, the granules of the anterior surface very fine, 

 those of the lower surface a little coarser, those of the upper 

 much coarser and pointed ; the upper anterior edge armed 

 with 6 spines, 1 and 2 close together, the latter longer, 3 and 

 4 about equal to 1, the space betweeen 2 and 3 equal to the 

 space between 3 and 4, 5 and 6 a little smaller than 3 and 4, 

 the space between them about equal to that between 4 and 5 

 and twice that between 3 and 4; the above described spaces 

 occupied by larger and smaller spinules, the 6th separated 

 from the distal end by a space which is greater than a third 

 of the length of the femur ; the lower edge armed with 5 

 longer spines, which gradually decrease in length distally, 

 the first being about twice the length of the fifth, which is 

 not much longer than some of the spinules which lie between 

 the spines ; between the first and the proximal angle of the 

 femur there are three of these spinules, the lower of which is
