Tibial process of palp stout, straightish, hooked at apex ; tibias of legs with 3 pairs of spines ; 2nd leg considerably longer than 1st and about seven times as long as carapace ; tibiae of palp with only 1 spine... ritfilatus, sp. n. Sparassus (Olios) alluaudi Simon (Ann. Soc Ent. Fr. 1887, p. 264), from Assinie, resembles S. batesi in certain characters, for example in having the carapace as wide as long and the mandibles black; but according to Simon the eyes of the anterior line are procurved in S. alluaudi, whereas they are straight in S. batesi and the upperside of the abdomen is ornamented with a longitudinal, lanceolate fuscous band. PALYSTODES, gen. nov. Carapace about one-third longer than wide, rather low, moderately convex, flat above longitudinally; the cephalic area not raised. Eyes of posterior line nearly equidistant, very slightly recurved, the medians larger than the laterals, which are sessile ; those of anterior line also equidistant, their lower edges on a level, the medians much smaller than the laterals, their diameter less than the radius of the latter; clvpeus low, less than the diameter of anterior medians ; quadrangle of median eyes much longer than wide, wider behind than in front, the eyes subequal. Mandibles armed below with 3 teeth in front and 3 behind. Legs 1, 2, 4, 3, completely laterigrade, very long and slender. Becognizable from Palystes, to which it is most nearly related, by having the carapace narrower and its upper surface flat from the eyes to the posterior end of the thoracic fovea. In Palystes the carapace is strongly convex longitudinally. PALYSTODES PLUMOSUS, sp. n. (Plate LVIII. figs. 31, 31a.) d. Colour. Carapace castaneous, covered with a coating of brownish hairs, mottled with darker and lighter patches; mandibles deep mahogany, clothed with mottled greyish-yellow hairs ; labium and maxilla? black ; sternum black, striped with red bands, which cross it transversely on a level wdth the coxa?; coxae covered with rich yellowish-red hairs, black in front; legs blackish, femora spotted with white below, white spotted with black above, with tufts of brownish hairs in front; patella? white below ; tibiae with two white stripes below, one median and one apical; uppers'de of tarsi and protarsi brownish, mottled with tufts of hair ; scopula? of tarsi and protarsi rusty red : the colouring of the 4th leg less distinctly marked than that of the others ; apex of femora, tibiae, and protarsi, especially of 4th leg, with short tufts of hair, somewhat as in some species of Pandercetes; palpi black, mottled above, the hairs more uniformly flavous below; tarsus covered with ferruginous hairs, fuscous apically below. Abdomen mottled with greyish-yellow above, with tufts of brown hairs, a short anterior mediau black stripe, and on each side of the middle line a large semicircular black stripe, the anterior aud posterior ends of which 57* |
