Mr. J. Blackwall on newly discovered species of Araneidea. 21 



extremity, curvilinear : lip semicircular and prominent at the apex : 

 sternum broad, convex, glossy, and heart-shaped. These parts 

 have a dark brown hue, the maxillae being the palest. The first 

 pair of legs 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 slightly pectinated, and the inferior 

 one is inflected near its base. Eyes seated on black spots ; the four 

 intermediate ones describe a trapezoid whose anterior side is the 

 shortest, and those of each lateral pair are placed obliquely on a 

 tubercle and are nearly contiguous ; the anterior eyes of the tra- 

 pezoid are seated on a small protuberance and are much the 

 least of the eight. Abdomen oviform, pointed at the spinners, 

 thinly clothed with hairs, glossy, convex above, projecting over 

 the base of the cephalo-thorax ; the upper part is of a yellowish 

 brown colour mottled with dull white ; a narrow, dentated, black 

 band extends along the middle, whose continuity is frequently 

 interrupted, or broken into black spots, about one-third of its 

 length above the spinners, and from these spots fine oblique 

 lines of the same hue pass to the sides, which, with the under 

 part, have a brown-black tint ; a yellowish brown band mottled 

 with dull white extends along each side, and the two unite above 

 the anus ; the sexual organs are highly developed and very pro- 

 minent ; there is a process connected with their superior margin 

 which is enlarged at its extremity and curved downwards, and a 

 minute one occurs on the inferior margin ; their colour is brown 

 faintly tinged with red. Some individuals have the medial, den- 

 tated band much more perfectly defined than others. 



In their colours and in the design formed by them the sexes 

 closely resemble each other, but the male is rather smaller than 

 the female, and the anterior part of its cephalo-thorax, where the 

 eyes are seated, is provided with porrect hairs. The humeral 

 joint of its palpi is moderately long ; the cubital joint is short, 

 and has a long bristle projecting from its extremity, in front ; 

 the radial, which is larger than the cubital joint, has a long 

 bristle projecting from its base, in front, and is gibbous under- 

 neath ; the digital joint is somewhat oval, having two lobes on 

 the outer side ; it is convex and hairy externally, concave within, 

 comprising the palpal organs ; they are highly developed, pro- 

 minent, complex with projecting points and processes, one of the 

 latter, situated near the middle, and another on the inner side, 

 which is slightly bifid at its extremity, being the most conspi- 

 cuous ; their colour is red-brown. 



Mr. R. H. Meade found specimens of this Linyphia in May 

 1852, in a wood near Bingley, and in the neighbourhood of 

 Bradford, in Yorkshire.
