pointed process on the outer side ; and their colour is pale and 

 dark red-brown intermixed. The convex sides of the digital 

 joints are directed towards each other. The abdomen is oviform, 

 thinly clothed with hairs, convex above, projecting over the base of 

 the cephalothorax, and has a small conical prominence on each side 

 of its anterior extremity ; it is of a yellowish-brown colour, reti- 

 culated with fine brown lines ; a pale yellow longitudinal streak 

 in front of the upper part is followed by a large leaf-like band, 

 with sinuous margins, which tapers to the spinners ; this band 

 is soot-coloured, freckled with yellowish-brown, and is marked 

 with black transverse lines, whose extremities are curved forwards; 

 the anterior part comprises a transverse pale yellow band, reti- 

 culated with brown, whose pointed extremities are in contact 

 with the lateral conical prominences, and on each side of the 

 medial line there are two dark brown indented spots, disposed 

 in pairs, which describe a quadrilateral figure whose posterior 

 side is the longest; the sides are the darkest in the medial line, 

 and are marked with oblique black streaks ; the middle of the 

 under part is of a dark brown colour, freckled with yellowish- 

 white, and there are two conspicuous spots of the latter hue 

 placed transversely near the spinners.

The cephalothorax is compressed before, somewhat pointed in 

 front, rounded on the sides, thinly clothed with hairs, convex, 

 glossy, and has a large oblong indentation in the medial line ; 

 the fakes are powerful, conical, vertical, convex in front, near 

 the base, and armed with a few teeth on the inner surface ; the 

 sternum is heart-shaped, with minute eminences on the sides, 

 opposite to the legs ; the legs are robust, provided with hairs 

 and spines, the latter being the strongest and most abundant on 

 the inner surface of the tibiae of the second pair; the first pair 

 is the longest, the second and fourth pairs are equal in length, 

 and the third pair is the shortest ; the tarsi are terminated by 

 claws of the usual number and structure. These parts are of a 

 brownish-red colour ; the sternum is the palest, and the extre- 

 tremity of the joints of the legs, the middle of the anterior part 

 of the cephalothorax, and the medial indentation have a brown 

 hue. The maxilla? are short, straight, and enlarged at the ex- 

 tremity ; and the lip is semicircular, but somewhat pointed at 

 the apex. These organs have a reddish-brown hue at the base, 

 that of their extremities being brownish-yellow. The palpi arc 

 short, and of a reddish-yellow colour, with the exception of the
