blackish markings, which are fused to form continuous dark patches on the cephalothoracic 

 area and first abdominal segment, the centre of these divisions of the 

 scutum being occupied by a well-defined and almost rectilinear band of fjjo 



yellowish ground-colour. Posterior segments with the dark markings TjULl 



more isolated ; the bases of the central spines of these segments are ringed # »■ '%;, '|||\ 

 round with black (Fig. 8). Ventral surface often darkened, but the coxae [i!jr\'V^I$ 

 and trochanters are pale in colour. Distal segment of chelicera pale- rj| W}£ '^'J 

 coloured ; palps slightly darkened ; the legs banded. %i> &jj£ m 



Scutum. Grooves of scutum rather indistinct. In addition to the ^^^T 



large anterior (unpaired) thorn, the cephalothoracic area is furnished F - g Iba i onius 

 posteriorly with a row of thorns and conical tubercles, and a somewhat flavopictus, n. 

 similar row is present on each of the abdominal segments. These projec- f body (Cheli- 

 tions usually diminish in size towards the outsides of the segments, the °er« diagram- 

 central pairs being of rather large size. The anterior (unpaired) thorn and 

 the central pair of the row in the hinder part of the cephalothoracic area are especially 

 long, and the thorns placed on either side of the central pair of the series on the third 

 abdominal segment are also very long, sometimes almost equalling them in length. The 

 projections of the row in the hinder part of the cephalothoracic are six in number, 

 the four outer ones being of very small size. Those of the first and second abdominal 

 segments number eight, the central pairs being of moderate size. The projections on the 

 third abdominal segment are also eight in number, but, as mentioned above, in this row 

 those placed next to the central pair are much the largest. Those of the fourth abdominal 

 segment are six in number, the central pair being of moderate size. Three large thorns 

 are present in the middle of the fifth abdominal segment, which is the last of the scutum. 

 A number of scattered granules are present, especially round the large anterior thorn, but 

 most of the surface is free from granules. 



Each of the free abdominal segments is furnished with a row of small thorns or 

 tubercles. 



Palp slightly longer than the body, its armature very similar to that of /. inscriptus, 

 Lom. Femur with a single inner spine at the distal end and with 4 — 5 outer spines 

 below ; patella with two inner and one outer, tibia with three inner and three outer, 

 tarsus with two inner and two outer, and with a pair of minute spines (at the distal end) 

 besides. 



Legs. Femur of first leg furnished with five long ventral spines, and with a number 

 of tubercles and spines above. Patellae of legs of all four pairs with a pair of small conical 

 tubercles at the distal end above, each of which bears a hair (smaller tubercles are some- 

 times present behind this apical pair, and at the apex of the femora). Number of tarsal 

 segments (in the adult example) 3, 9, 5, 5. 



Measurements in mm. Length of body 2 - 5, of palp 2 - 75. 



Material. An adult male example (the type) from Mare aux Cochons, Mahe, and 

 three young examples from the Foret Noire district, Mahe. 



Remarks. Very closely allied to /. inscriptus, Lom., chiefly differing in the coloration 

 of the dorsal surface, in the presence of a pair of small conical tubercles on the patellae of
