Show 856 MR. R. I. POCOCK ON SCORPIONS, PEDIPALPS, [Nov. 14, oblong silvery patch of hair on the upperside between the ocular tubercle and the posterior vertical tubercles, and a silvery patch on the upperside of the lateral tubercles ; mandibles deep brown; sternum bluish black, with central silvery patch ; maxilla? and labium black ; coxa? of legs deep brown with bluish tint; trochanters and femora red ; remaining segments nearly black, with bluish lustre especially below; a white band at base of tibia? and protarsi below, the tibial band broad only on the 1st leg, also a conspicuous white tarsal band on 4th leg; palp with femur red, the other segments blackish with white spots above. Abdomen blackish above and below, yellow at the sides anteriorly, the upper-side with a vertically interrupted transverse silver band behind the anterior row of tubercles, and a series of silvery patches and lines forming a longitudinal median band extending over two thirds of the upper surface between the transverse silvery band and the posterior tubercle ; sides of upper surface wdth narrow transverse silvery stripes ; lower surface with a row of three silvery spots on each side, extending from the epigastric fold to the sides of the spinning-mammilla?. Cephalic tubercles long, subspiniform, much longer than ocular tubercle. Length of carapace equal to width of head, including ocular tubercles, and as long as protarsus of 1st leg, shorter than protarsus and tarsus of 4th leg by at least half the length of the tarsus. Abdominal processes normal in number, as, for example, in G. mitralis, and all small and tuberculiform ; the bifid projection above the spinners rather prominent. Tibia? and protarsi of legs normally impressed above. Vulva as in figure (Pl. L V . fig. 5 b). Measurements in millimetres.-Total length 14; length of carapace 6, of abdomen 10, width of abdomen 11. Loc. Benito Biver (67. L. Bates). Easily recognizable from the S. and E. African species of the genus by the form of the vulva, and by colour, the almost complete absence of the white band at the base of the tibia on the 2nd, 3rd, and 4th legs being exceptional. CcEROSTRIS ALBESCENS, sp. n. (Plate LVII. fig. 16.) Allied to the East-African G. nodulosa Pocock (P. Z. S. 1898, p. 514, pl. xii. fig. 7). Hairy clothing of head mesially white, laterally golden yellow; upperside of abdomen covered with greyish-white hairs, diversified with black spots on the tubercles, sigilla, and elsewhere, and with narrow transverse black lines which laterally unite, circumscribing transversely elongate pentagonal areas; lower side of abdomen black ; femora steel-blue; upperside of patella, tibia, protarsus, and tarsus covered with silvery-white hairs, and varied with pale golden yellow ; extremity of protarsus of 1st and in a lesser degree of 2nd leg slightly infuscate ; 3rd and 4th legs more diversified than 1st and 2nd : legs banded below as in G. nodulosa |
