403 ME. J. BLAOKWALL ON SOME TUSCAN SPIDEES. 



immediately above the frontal margin, the two lateral ones being 

 rather the largest, and the two intermediate ones much the smallest 

 of the eight j the posterior row is greatly curved, with its convexity 

 directed forwards ; and each lateral eye is seated on a tubercle. The 

 cephalothorax is compressed before, rounded in front and on the 

 sides, convex, clothed with yellowish-grey hairs, and is of a dull 

 yellow colour ; a curved, soot-coloured line passes from each lateral 

 eye of the posterior row to a narrow indentation in the medial line of 

 the posterior region, where the two meet in an angle ; and in the 

 space between them there are a few irregular lines of the same hue ; 

 the lateral margins are soot-coloured ; and on each side there are lines 

 of the same hue describing a series of contiguous triangles whose 

 vertices are directed towards the middle, the area enclosed by each 

 being of a yellow-brown colour. The falces are powerful, conical, 

 vertical, and armed with strong teeth on the inner surface; the 

 maxillae are short, enlarged and rounded at the extremity, and some- 

 what inclined towards the lip, which is nearly quadrate, being rather 

 broader at the base than at the apex. These parts are of a very dark 

 reddish-brown hue, the falces being the darkest, and the extremity of 

 the raaxillaj and apex of the lip much the palest. The sternum is 

 nearly' circular, glossy, and of a dull yellow colour, with small pro- 

 minences on the sides, opposite to the legs, on which are seated 

 minute brown spots ; and two very obscure lines of the same hue on 

 the anterior part converge to the middle, where they meet in an 

 • angle. The legs are robust, and provided with hairs and long sessile 

 spines, two parallel rows of the latter occurring on the inferior surface 

 of the tibiic and metatarsi ; the coxbc, femora, and genua arc of a dull 

 yellow hue, with soot-coloured spots ; the tibiye, metatarsi, and tarsi are 

 of n dark red-brown colour, the tarsi, and the tibiic and metatarsi of 

 the third and fourth pairs being the palest ; the fourth pair of legs is 

 rather the longest, then the first, and the third pair is the shortest; 

 each tarsus has two curved, slightly pectinated claws at its extremity, 

 below which there is a small scopula. The palpi are of a dull yellow 

 colour, the base of the radial joint having a brown hue, and the 

 digital joint, which is terminated by a curved, dentated claw, having 

 a tinge of red. The abdomen is oviform, hairy, convex above, 

 and projects over the base of the cephalothorax ; it is of a dull )'ellow 

 hue, with a soot-coloured band extending along the middle of the 

 upper part, which is broad for rather more than a third of its length, 

 and has somewhat irregular lateral margins; it then becomes abruptly 

 narrower and tapers towards the spinners ; from each side of this 

 band broad irregular bands of the same hue, more or less confluent, 

 pass obliquely to the sides ; all these bands are densely freckled with 

 ,dull yellow ; the middle of the under part is soot-coloured, mottled 

 with dull yellow ; and the £exual organs, which are highly developed
