Mr. J. Blackwall on newly discovered species 0/ Araneidea. 99 



exterior angle. Lip semicircular, prominent at the apex, and, 

 like the sternum, which is heart-shaped, of a very dark brown 

 colour. Cephalo-thorax oval, convex, glossy, with an indentation 

 in the medial line of the posterior region, and some coarse hairs, 

 directed forwards, behind the eyes; its colour is dark brown. 

 Eyes disposed on black spots on the anterior part of the cephalo- 

 thorax ; the four intermediate ones form a trapezoid whose ante- 

 rior side is the shortest, and those of each lateral pair are seated 

 obliquely on a protuberance and are nearly contiguous ; the an- 

 terior eyes of the trapezoid are the smallest of the eight. Legs 

 long, slender, provided with hairs and spines, and of a red colour ; 

 the first pair is the longest, then the second, and the third pair 

 is the shortest ; each tarsus is terminated by three claws ; the 

 two superior ones are curved and minutely pectinated, and the 

 inferior one is inflected near its base. The palpi are short, and 

 resemble the legs in colour, with the exception of the digital 

 joint, which is dark brown ; the radial joint is stronger than the 

 cubital, and has some long hairs in front ; the digital joint is 

 somewhat oval, having a large lobe on the outer side, near its 

 base ; it is convex and hairy externally, concave within, compri- 

 sing the palpal organs, which are highly developed, complicated 

 in structure, with a broad, compressed, curved process projecting 

 nearly at right angles from their base, on the outer side, and are 

 of a dark reddish brown colour. Abdomen oviform, very spa- 

 ringly supplied with short hairs, convex above, projecting over 

 the base of the cephalo-thorax ; it is of a yellowish brown colour 

 on the upper part and sides, a series of black angular lines, 

 whose indistinct vertices are directed forwards, extending along 

 the middle of the former ; the extremities of the anterior lines of 

 the series are much the most strongly marked, and a small yel- 

 lowish white spot occurs immediately above the spinners; the 

 under part is of a pale brown colour. 



This species was found among juniper bushes at Southgate in 

 May.
