286 Mr. J. Blackball on new species o/Lycosa. 



armed with a curved fang at the extremity and a few teeth on 

 the inner surface : the maxillse are short, straight, and enlarged 

 and rounded at the extremity : the palpi are moderately long, 

 and are terminated by a curved, pectinated claw. These parts 

 have a red-brown hue, the maxillje being the palest, and the 

 palpi the darkest at their articulations. The lip is nearly 

 quadrate, being rather broader at the base than at the apex, 

 and is of a dark brown colour. The sternum is heart-shaped, 

 clothed with greyish hairs, and is of a red-brown hue, with an 

 oval space in the middle bounded by a fine, dentated, brown- 

 black line, and has spots of the same hue on the lateral margins. 

 The legs are long, moderately robust, provided with hairs and 

 sessile spines, and of a red-brown hue, with dark brown streaks, 

 spots and annuli ; the fourth pair is the longest, then the first, 

 and the third pair is the shortest ; each tarsus is terminated by 

 three claws; the two superior ones are curved and pectinated, 

 and the inferior one is inflected near its base. The abdomen 

 is oviform, haiiy, convex above, and projects over the base of 

 the cephalo-thorax ; it is of a reddish-brown colom-, the under 

 part being the palest, and has on each side of the upper part a 

 strongly dentated, brownish-black band; these bands taper to 

 the spinners, where they unite, and from some of theu' larger 

 exterior angles, rows of brownish-black spots pass obliquely to 

 the sides, which are marked with other spots of the same hue ; 

 in the anterior part of the space comprised between the dentated, 

 brownish-black bauds there is an oblong-oval, reddish-brown 

 mark, bounded by a fine black line having an acute angular 

 point on each side and its posterior extremity bifid ; the sexual 

 organs, which are highly developed and prominent, have a dark 

 reddish-brown colour, and that of the branchial opercula is 

 brown. 



Two adult and two immature females of this Lycosa were 

 forwarded to me in Wales in December 1856, by Mr. R. H. 

 ^Icade. The two former were discovered by 0. P. Cambridge, 

 Esq., of Bloxworth House, in Dorsetshire, under a stone, near 

 Pennsylvania Castle, in the Isle of Portland, on the 29th of 

 September 1854; and the two latter were captured in July 1854, 

 in Morden Park, near Bloxworth House, by the same gentleman, 

 who has kindly permitted me to describe the species.
