Eyes unequal, the central quadrangle scarcely broader than long, 

 the anterior side shorter than the posterior. The eyes of both 

 the anterior and posterior rows appear to be about equally sepa- 

 rated. The height of the retreating elypeus rather exceeds the 

 diameter of the fore-central eyes. The fore-lateral eyes are much 

 the smallest. 



Legs neither long nor very strong, 1-2-3— i, fiii'nished with 

 hairs and a few fine spines ; femora black, with a broad clear 

 whitish-yellow aunulus ni\ar their base ; this annulus does not 

 extend, in the first pair of legs, beyond the anterior part and 

 sides ; the rest of the legs is brown ; the tibiae semi-aunulated with 

 yellowish, the tarsi and metatarsi are palest, the hairs on the pale 

 annuli are grey. 



Palpi similar in colours and markings to the legs. 



Falces powerful, vertical, roundly prominent at their base in 

 front. Colour deep shining brown. 



Maxillce and labium deep brown, tipped with pale yellowish-white. 



Sternum deep brown, with small eminences opposite to the 

 insertion of the legs and clothed with adi)ressed grey hairs. 



Abdomen oval, obtuse anteriorly, broadest in the middle, slightly 

 prominent a -little way above the spinners. Colour sooty-black, 

 with a somewhat velvety look, marked on the upperside with 

 yellowish-white oval and round spots of different sizes, forming a 

 regular pattern ; tliese spots are all clotliied with silver}^ S^'^^y 

 hairs ; four form a square at the foi'e-side, followed by four other 

 smaller ones, towards the spinners, the tirst two in a transverse 

 line, and on each side of these are several others ; on each side of 

 the abdomen towards the spinners are some parallel irregular 

 white lines, and in front of them, near the spiracular plates, is a 

 rather large Avhitish-yellow patch. The underside is velvety black ; 

 at the middle on each side is a slightly curved longitudinal line of 

 small white spots, and across the middle are two parallel white 

 lines rather near to each other. Spinners short, compact, black- 

 brown, and on each side of their base are two yellowish-white 

 elongate spots. The genital aperture, in front of a small semi- 

 circular prominence, is rather inconspicuous but of characteristic 

 form.
