34*8 Mr. J. Blackwall's Characters of some 



Linyphia annulipes, 



Cephalothorax oval, prominent before, glossy, with an in- 

 dentation in the medial line of the posterior region; it is of a 

 pale yellowish-brown colour, with a fine line of black on each 

 of the lateral margins, immediately above which is a longitu- 

 dinal row of triangular, black spots, and along the middle 

 extends a black band bifid in front. Eyes placed on black 

 spots, their disposition and relative size being the same as in 

 the other species of the genus. Mandibles long, conical, 

 armed with two rows of teeth on the inner surface, and in- 

 clined towards the pectus, which is heart-shaped and of a pale 

 yellowish-brown colour. The maxillae and lip have the same 

 form as those of the Linyphia generally; their colour, and that 

 of the mandibles, is yellowish-brown, the maxillae being the 

 palest. Legs long and slender, provided with a few upright 

 spines; they are of a pale yellowish-brown colour with brown- 

 ish-black bands. Each tarsus has three claws at its extre- 

 mity ; the two superior ones are pectinated, and the inferior 

 one is inflected near its base, where there are one or two very 

 minute teeth. The palpi have numerous long, erect spines, 

 particularly on their ultimate and penultimate joints, and are 

 terminated by a single claw slightly curved, and minutely 

 dentated about a third of its length ; their colour is similar to 

 that of the legs. Abdomen oval, convex above, projecting 

 over the base of the cephalothorax; upper part greenish 

 white reticulated with fine, yellowish-green or greenish-brown 

 lines, and having along the middle a series of greenish-brown 

 bands of an angular form, whose vertices are directed for- 

 wards. A curved, black band, comprising four white spots in 

 front, extends from the anterior part of the abdomen, con- 

 tiguous to the cephalothorax, rather more than half its length 

 along the sides, and from each of its extremities a black line 

 stretches obliquely upwards and forwards; between the ex- 

 tremities of the curved band and the spinners are two, oblique, 

 black streaks united near the middle, and below the band and 

 streaks are numerous yellowish-white spots. Inferior part of 

 the abdomen reddish-brown marked with a few minute, yel- 

 lowish-white spots. Above the exterior margin of the spira- 

 cles, which are of a pale yellowish-white colour, a black streak 

 occurs. A long, depressed process of a red- brown colour, di- 

 rected backwards, is in connexion with the sexual organs.
