POCOCK ON SCORPIONS, PEDIPALPS, [Nov. 14, But although there is thus a possibility of resuscitating Harpax-theria, it must be remembered that the apparently greater narrowness of the cephalothorax in P. belandana may be due to artificial shrinkage, and that too great stress should not be laid upon the tibial spine-armature, seeing that in the male of P. gregorii, which is apparently congeneric with P. antilope and P. occidentalis, the tibia of the 1st leg is armed with 5 spines, the 2nd with 3, and the 3rd and the 4th with 2 each. Again, before Harpaxotheria be rescued from the world of synonyms, it will have to be ascertained that it is distinguishable from Karsch's previously established genus Pelinobius, a point about which great doubt may be entertained. PHONEYUSA OCCIDENTALIS (Lucas). Mygale occidentalis, Lucas, Thomson's Arch. Ent. ii. p. 380 (1858). 2 . Colour. Integument of carapace, mandibles, and legs uniform deep reddish brown, covered with deep olive-green bairs; the distal segments of the palpi and of the first two pairs of legs much redder in the young; femora, patella?, tibiae, and protarsi with a fringe of yellowish-pink hairs at their distal extremities; abdomen greenish brown; the long bristles on the legs and abdomen reddish. Carapace considerably longer than patella aud tibia of 4th and 2nd legs, a little longer than those of 1st, longer than tarsus and protarsus of 4th, much longer than those of 1st, a little longer than patella, tibia, and tarsus of palp ; its width a little less than the area between the posterior emargination and the ocular tubercle, much exceeding the 4th protarsus and just exceeding protarsus and tarsus of 1st leg, a little longer than femur of 4th leg. Legs 4, 1, 2, 3 ; 4th exceeding 1st by one fourth the length of its tarsus; tibiae with a pair of distal spines below, protarsus of 1st with 1 median apical spine, of 2nd with 3 spines, of 3rd and 4th with about 9 spines in a transverse row. Measurements in millimetres.-Total length 62; length of carapace 32, width 26 ; length of palp 47, of 1st leg 78, of 2nd leg 69, of 3rd leg 63, of 4th leg 79, patella and tibia of 1st 30, of 4th 27, protarsus of 4th 21 (legs and palpi measured from base of femur). In younger females the legs are much longer as compared with the carapace than iu the adult. Loc. Benito Biver (G. L. Bates). This species has not been hitherto recognized since it was first established. It certainly differs from P. belandana Karsch (Berl. ent. Zeit. 1884, p. 348), from Niam Niam in Central Africa, in bavins: only a pair of spines at the apex of the tibia?, instead of a large number as in P. belandana ; that is to say, 9 on the 1st tibia, 8 on the 2nd, & c In P. belandana also the sternum is nearly twice as long as wide (15: 8), whereas in P. occidentalis the length is only a little greater than the width (9 : 7*5). In the character of the sternum P. occidentalis resembles P. biittneri Karsch (Berl. ent. Zeit. 1886, p. 83), from |
